10 less than twice a number w
If the number is, say, N, then “10 less than twice the number” is 2N - 10.
Pretty simple. take the number given, multiply it by 2, then subtract 10 from the answer.
If N is 7, then “10 less than twice the number” is 2*7 - 10 = 14 - 10 = 4.
Oil prices are projected to increase by 75% by next May. A quart of oil currently costs $2.15. What is the projected cost of a gallon of oil next May?
Answer:
$3.7625
Step-by-step explanation: I may be wrong but...
If you find 75% of $2.15 it is equal to $1.6125.
Since in "increases" we are going to add $1.6125 to $2.15.
You get the answer of $3.7625.

Jamal wrote the inequality x/16 <6 . Which situation best represented by this inequality Helpppppp
Given problem;
Inequality equation;
[tex]\frac{x}{16}[/tex] < 6
Before we solve, let us first translate this problem.
It simply states that for what value(s) of x will the expression be less than 6.
To find this value, we can simply carry out the normal mathematical simplification.
Simply multiply both sides by 16 to reduce the fraction;
16 x ([tex]\frac{x}{16}[/tex]) < 6 x 16
On the left hand side, 16 will cancel out;
x < 96
Any value for which x is less than 96 will make the solution of this problem less than 6.
For example, 95;
[tex]\frac{95}{16}[/tex] = 5.93
This value is less than 6

The length of a rectangle is 4cm more than three times its width. If the
perimeter is more than 56 cm, what are the minimum possible dimensions
of the rectangle?
Answer:
22cm by 6cm
Step-by-step explanation:
Width = x
Length = 3x + 4
x + x + 3x + 3x + 4 + 4 = 8x + 8
Perimeter = (8x + 8) cm
56 - 8 = 48cm
48/8 = 6
6 = x
Width = 6cm
Length = 22cm
Please mark as Brainliest, thank you!
The required possible dimensions are the length of a rectangle is 22 cm and the width is 6 cm.
What is the perimeter of the rectangle?The perimeter of a rectangle is defined as the addition of the lengths of the rectangle's four sides.
The perimeter of a rectangle = 2(L+W)
Where W is the width of the rectangle and L is the length of the rectangle
Let the width of the rectangle is x
So the length of the rectangle= 3x + 4
The perimeter of a rectangle = x + x + 3x + 3x + 4 + 4
The perimeter of a rectangle = 8x + 8
The perimeter of a rectangle = (8x + 8) cm
56 - 8 = 48cm
48/8 = 6
6 = x
So the width of the rectangle = 6 cm
So the length of the rectangle = 22cm
Thus, the required possible dimensions are the length of a rectangle is 22 cm and the width is 6 cm.

3x^5 + 12x^4 − 36x^3
Answer: 3x^3(x - 2)(x + 6)
Step-by-step explanation:
For this problem, you find a GCF first
The GCF in this case is 3x^3 since each term can be divided by both 3 and x^3
3x^3(x^2 + 4x - 12)
x * x = x^2
(-2 + 6) * x = 4x
-2 * 6 = -12
Since -2 and +6 work for the factors, the answer is 3x^3(x - 2)(x + 6)
A pool measuring 12 meters by 30 meters is surrounded by a path of uniform width, as shown in the figure. If the area of the pool and the path combined is 1144 square meters, what is the width of the path?
The width of the path is __ meters?
Answer:
7 meters
Step-by-step explanation:
Notice that the figure has already been labeled. The variable x is used to represent the unknown width of the path
It is given that the area of the pool and the path combined is 1144 square meters.
Notice that the length of the combined area is 30 +2x and the width of the combined area is 12+2x
Recall that the formula for the area of a rectangle is A = L* W
Use the figure and the information given to write an equation for the area of the pool and path combined.
(12+2x)(30+2x) = 1144
Thus, solve the equation (12+2x)(30+2x) = 1144. The solutions to this equation are the values of x that satisfy the condition given in the problem.
Begin by rewriting the equation in the standard form
ax^2 + bx + c=0 First, multiply the binomials on the left side of the equation using the FOIL method.
(12+2x)(30+2x) = 1144
4x^2 + 84x +360 = 1144
Then move all terms to the left side of the equation, obtaining zero on the right side.
4x^2 + 84x +360 = 1144
4x^2 + 84x -784 = 0
Now that the quadratic equation is in standard form, factor the quadratic completely. First, factor out the greatest common factor (GCF). Then factor the trinomial.
4x^2 + 84x -784 = 0
4(x^2 + 21x -196 = 0
4(x - 7) (x + 18) = 0
Next, apply the zero-product principle and set each factor equal to 0. Solve each equation for x.
x - 7 = 0 or x + 28 = 0
x = 7 or x = -28
Remember that x represents the width of the path. Therefore, the proposed solution -28 does not make sense. The width of a path cannot be negative. Eliminate this proposed solution.
Check the solution -28 by substituting it into the original equation, (12+2x)(30+2x) = 1144 , and verifying that a true statement results.
The solution checks. Therefore, the width of the path is 7 meters.

What is the solution to the inequality 28 > 4 – 2p?
{p | p > –12}
{p | p 12}
{p | p < 12}
Answer:
The answer is
{p | p > –12}Step-by-step explanation:
[tex]28 > 4 – 2p[/tex]
Subtract 4 from both sides of the equation
That's
[tex]28 - 4 > 4 - 4 - 2p \\ 24 > - 2p[/tex]
Divide both sides by - 2
[tex] \frac{24}{ - 2} > \frac{ - 2p}{ - 2} \\ p < - 12[/tex]
Since the denominator was negative the sign will change
We have the final answer as
p > - 12Hope this helps you

Drag each angle measure to the correct location on the image. Each angle measure can be used more than once. In the figure, two parallel lines are cut by two other parallel lines. The measure of one of the angles is labeled. Find the measures of the other angles and label them. 137° 52° 128° 38°
please help asap!
Answer:
Basically, all the wide (obtuse) angles are 112. the smaller(acute) ones are 52.
Step-by-step explanation:
Reasoning: 180-52=128. After that, just lots of reflection across angles.
From the figure, the measures of all the angles are:
A = 128
B = 52
C = 52
D = 52
E = 128
F = 52
G = 128
H = 52
I = 128
What are corresponding, alternate, and vertical angles?Corresponding angles are the angles that are formed when two parallel lines are intersected by the transversal.
Alternate angles are angles that occur on opposite sides of the transversal line and have the same size.
Vertical angles are angles that are opposite of each other when two lines cross.
We have,
A pair of vertically opposite angles are always equal to each other.
Corresponding angles are equal.
Alternate angles are equal.
B and C are vertically opposite angles.
So,
C = 52
B = 52
We know that from the figure,
1 + B = 180
1 + 52 = 180
1 = 180 - 52 = 128
1 and A are alternate angles so,
A = 128
Now,
D and C are corresponding angles.
D = C = 52
D + E = 180
E = 180 - D
E = 180 - 52
E = 128
E and I are interior alternate angles.
E = I = 128
I and G are vertical angles.
I = G = 128
F + I = 180
F = 180 - 128 = 52
F and H are vertical angles.
F = H = 52
Thus,
From the figure, the measures of the angles are:
A = 128
B = 52
C = 52
D = 52
E = 128
F = 52
G = 128
H = 52
I = 128

A tank has 55 gallons of water in it. The water drains from the tank at the rate of 3 gallons per minute. The function f(x) models the number of gallons of water in the tank after x minutes. Find f^-1(15) and explain what it represents.
Please help!!!!
Step-by-step explanation:
The initial amount is 55 gallons, and the rate is -3 gal/min. So using slope-intercept form, the equation is:
f(x) = -3x + 55
To find the inverse function, switch x and y, then solve for y.
x = -3y + 55
3y = -x + 55
y = (-x + 55) / 3
f⁻¹(x) = (-x + 55) / 3
Evaluated at x = 15:
f⁻¹(15) = (-15 + 55) / 3
f⁻¹(15) = 40 / 3
The original function told us number of gallons f(x) at time x.
The inverse function tells us time f⁻¹(x) at number of gallons x.
So there are 15 gallons in the tank after 40/3 minutes, or 800 seconds.
Brooke found the equation of the line passing through the points (–7, 25) and (–4, 13) in slope-intercept form as follows. Step 1: m = StartFraction 13 minus 25 Over negative 4 minus (negative 7) EndFraction = StartFraction negative 12 Over 3 EndFraction = negative 4. Step 2: y = negative 4 x + b. 25 = negative 4 (negative 7) + b. 25 = 28 + b. 25 minus 28 = 28 + b minus 28. b = negative 3. Step 3: y = negative 3 x minus 4 What was Brooke’s error? She found the incorrect slope in step 1. She mixed up the x- and y-coordinates when she plugged in the point in step 2. She found the incorrect y-intercept in step 2.
