Solve for u.
|5u + 15| = 10
Answer:
-1 and -5
Step-by-step explanation:
You must account for negative u values (which the abs nullifies).
So [tex]5u+15=10[/tex] and [tex]5u+15=-10[/tex] is what we have to solve for.
As for usual equations, isolate the u variable.
5u + 15 = 10
5u + 15 (-15) = 10 (-15)
5u = -5
[tex]\frac{5u}{5}=\frac{-5}{1}[/tex]
u = -1
Now you can do the same operation for the other equation and you should get u = -5.
Let's make sure we did it right by replacing u with one of our solutions (-1 or -5).
[tex]|5(-1)+15| = 10\\10 = 10[/tex]
That's true. What about the other one?
[tex]|5(-5)+15|=10\\10=10[/tex]

5x+10y=30
solve for y
Answer:
y= 3 -0.5x
Step-by-step explanation:
5x + 10y = 30
subtract 5x from each side to get 10y by itself
10y= 30-5x
divide each side by 10
y= 3 - 0.5x

a paint store makes three batches of a color called Sunset Orange using the recipe shown.
1/2 of the paint is red
1/3 of the paint is yellow
1/6 of the paint is white
Each batch contains a different total amount of paint.
Drag numbers to show how much of each color should be used in each batch of Sunset Orange
Answer:
Suppose that the batch has N liters of paint.
we know that the recipe is:
1/2 of red paint
1/3 of yellow paint
1/6 of white paint.
Then, out of the N liters, 1/2 is red.
This means that we must use:
N/2 liters of red paint.
And the same for the other two colors:
N/3 liters of yellow paint
N/6 liters of white paint.
When we add those 3, we have:
(N/2 + N/3 + N/6) = (3*N/6 + 2*N/6 + N/6) = N.
Now, if for example N = 2
Then the batch has 2 liters of paint, this would mean that we must use:
2/2 liters of red paint
2/3 liters of yellow paint
2/6 liters of white paint.

Find the slope of the line. On a coordinate plane, a line goes through (0, negative 2) and (2, negative 4). a. -1 c. -2 b. 2 d. 1
Answer: Choice A) Slope = -1
==============================================
Explanation:
The two points given to us are (x1,y1) = (0,-2) and (x2,y2) = (2,-4)
Subtract the y coordinates
y2-y1 = -4-(-2) = -4+2 = -2
Subtract the x coordinates in the same order
x2-x1 = 2-0 = 2
Divide the two results to get the slope m
m = (y2-y1)/(x2-x1)
m = -2/2
m = -1

Answer:
x = -3, y=2
Step-by-step explanation:
x+3y =3
3y -2x =12
Solve the first equation for x
x = 3-3y
Substitute this into the second equation
3y -2(3-3y) =12
Distribute
3y -6 +6y =12
Combine like terms
9y -6 =12
Add 6 to each side
9y-6+6 =12+6
9y =18
Divide each side by 9
9y/9 =18/9
y = 2
Now find x
x = 3 -3y
x = 3-3(2)
x = 3-6
x = -3
Answer:
x = -3 y = 2
Step-by-step explanation:
x + 3y = 3
2x - 3y = -12
3x = -9
x = -3
Solve the system of equations using substitution.
3x + y = 12
y = 3x
Answer:
y=3x⇒equation 1
substitute equation 1 in 3x+y=12
3x+3x=12
6x=12
x=12/6
x=2

A triangle has three sides(4x),(2x-6),and(10-x). Using the variable x, write an expression to define the perimeter
Answer:
5x+4
Step-by-step explanation:
well the perimeter is the sum of all sides
so we have
[tex]P=4x+2x-6+10-x\\\\P=(4x+2x-x)+(-6+10)\\\\P=5x+4[/tex]
Answer:
P = 5x+4
Step-by-step explanation:
To find the perimeter, sum the sides
A triangle has 3 sides
P = 4x+ 2x-6 + 10-x
Combine like terms
P = 4x+2x-x -6+10
P = 5x +5
Solve for Q
8q+12=4(3+2q)
Answer:
q = infinite amount of solutions
Step-by-step explanation:
Step 1: Write equation
8q + 12 = 4(3 + 2q)
Step 2: Solve for q
Distribute 4: 8q + 12 = 12 + 8qSubtract 8q on both sides: 12 = 12--------------------------------------------------------------
Distribute 4: 8q + 12 = 12 + 8qSubtract 12 on both sides 8q = 8qDivide both sides by 8: q = qWe see here that you can plug in any number q and it would render the equation true. You can also look at it as 2 linear lines that are same, and the same line has infinite amount of solutions.
Step 3: Check
Plug in q to verify it's a solution.
8(0) + 12 = 4(3 + 2(0))
0 + 12 = 4(3 + 0)
12 = 4(3)
12 = 12
8(1) + 12 = 4(3 + 2(1))
8 + 12 = 4(3 + 2)
20 = 4(5)
20 = 20
We also see in the check step that any value q works.
The solution to the equation 8q + 12 = 4(3 + 2q) is Q can be any real number.
We have,
To solve for Q in the equation 8q + 12 = 4(3 + 2q), we can follow these steps:
Step 1: Distribute the 4 to the terms inside the parentheses:
8q + 12 = 4 * 3 + 4 * 2q
Simplifying further:
8q + 12 = 12 + 8q
Step 2: Combine like terms on both sides of the equation:
8q + 12 = 12 + 8q
Step 3: Subtract 8q from both sides of the equation to isolate the q term:
8q - 8q + 12 = 12 + 8q - 8q
Simplifying further:
12 = 12
Step 4: Since both sides of the equation are equal, the equation is true for all values of q.
This means the solution is all real numbers.
Therefore,
The solution to the equation 8q + 12 = 4(3 + 2q) is Q can be any real number.

Lamont has purchased 20 trading cards and wants to have at least 50 trading cards. Write and solve an inequality to nd the number of trading cards Lamont needs. Select all of the true statements.
Given:
Lamont has purchased 20 trading cards.
He wants to have at least 50 trading cards.
To find:
The inequality for the number of trading cards Lamont needs and solve it.
Solution:
Let x be the number of trading cards Lamont needs.
He has 20 trading cards. So,
Total cards = x + 20
It is given that, he wants to have at least 50 trading cards. It means, total card must be greater than or equal to 50.
[tex]x+20\geq 50[/tex]
Subtract 20 from both sides.
[tex]x+20-20\geq 50-20[/tex]
[tex]x\geq 30[/tex]
Therefore, the required inequality is [tex]x+20\geq 50[/tex] and solution is [tex]x\geq 30[/tex].
The number of trading cards that Lamont needs will be at least 30 trading cards.
From the information given, we are informed that Lamont has purchased 20 trading cards and wants to have at least 50 trading cards.
Therefore, the number that will be needed more will be:
= 50 - 20 = 30
Therefore, he'll need at least 30 more cards.
