Answer:
x = 58
Step-by-step explanation:
trust me i got the same question today on khan and apparently i accidently pressed next
so...
the person that answered first had the right set up but miscalculated
anyway...
you have to subtract on both sides because 32 was positive and two different signs would be 0:
x+32 = 90 degrees
-32 -32
then 32 and -32 gets crossed out and then you do
90-32 = 58
you subtract because different signs...
therefore:
x=58
here's another way to solve it:
We simplify the equation to the form, which is simple to understand
x+32=90
We move all terms containing x to the left and all other terms to the right.
+1x=+90-32
We simplify left and right side of the equation.
+1x=+58
We divide both sides of the equation by 1 to get x.
x=58

We gotta mess with those exponents and their bases!
Remember that [tex]2^2 = 4[/tex]
So [tex]4^2[/tex] can be written as [tex](2^2)^2[/tex]
We just substitued 4 for [tex]2^2[/tex].
Now remember that that lonely 2 has a hidden exponent of 1. [tex]2 = 2^1[/tex]
So we have [tex]2^1 + (2^2)^2[/tex]
Remember what we do with exponents raised to exponents? We MULTIPLY them, so we get. [tex]2^1.+ 2^4[/tex]
Now we can just add the exponents.
[tex]2^{1+4} = 2^5[/tex]
I think I spot a winner.
Answer:
3^2 + 9Step-by-step
Since 2+4^2 is 16+2 which is 18 you need to find the expression equivalent to 18.25 doesn't work so eliminate that right away. 9^2=81 so that isn't right either. 2^3+9=17 so that is incorrect. Lastly, 3^2+9=18 so that is the correct answer.

Kendrick’s bill for lunch was $24.50. He left the server an 18% tip. What is the total amount that Kendrick paid for lunch including the tip?
Answer:
$28.91
Step-by-step explanation:
The first step is to calculate the amount of the tip. You multiply the price (24.50) by the tip amount (18% or 0.18). The product is 4.41. Then, you add the tip to the bill. 24.50+4.41=28.91.
Answer:

A triangle has a perimeter 12 cm and area 6 cm^2.
It is enlarged by a scale factor of 3 to produce a
similar triangle. What is the perimeter and area
of the new triangle?
Answer:
The new triangle will have a perimeter of 36 cm, and an area of 18 cm2.
Step-by-step explanation:
Given that the triangle whose perimeter is 12 cm and its surface is 6 cm2, and is lengthened by a scale factor of 3 to produce a similar triangle, the perimeter and surface of the new triangle arise from the following calculation:
Perimeter = 12 x 3 = 36 cm
Area = 6 x 3 = 18 cm2
Thus, the new triangle will have a perimeter of 36 cm, and an area of 18 cm2.

6(2 + y) - 2y
solve the problem
Please help, I will give brainliest. I am struggling badly.
Answer:
C) y = -1/4x
Step-by-step explanation:
find slope by selecting two points -- I used (0, 0) and (-4, 1)
slope is the difference of the y-values: 1 - 0 = 1
divided by the difference of the x-values: -4 - 0 = -4
slope = -1/4
the other thing you need to know is the y-intercept, which in this case is zero
so the equation is y = -1/4x
The sum of two numbers is 56. The difference of the 2 numbers is 16. What
is the product of the two numbers?
OA) 720
B) 735
OC) 748
OD) 759
Please help me!
Answer:
X+y=56 equation 1
X-y=16 equation 2
X+y+x-y=56+16
2x=72(divide Both side by 2)
X=36
X+y=56(from equation 1 to find y)
36+y=56
Y=56-36
Y=20
So their product is xy
36×20
720
So the answer is 720

check the solution.
y=x-7
y=-4+3
solution: (2,-5)
check in first eq:
check in 2nd eq:
Answer:
Both equations, when we replace the solution, generate identities.
Step-by-step explanation:
We are given the following system:
y = x - 7
y = -4x + 3
We are given the following solution.
(2,-5).
First equation:
We have to show that when x = 2, y = -5. So
y = x - 7
-5 = 2 - 7
-5 = -5
So ok
Second equation
We have to show that when x = 2, y = -5. So
y = -4x + 3
-5 = -4(2) + 3
-5 = -8 + 3
-5 = -5
We generate both identities, so the solution is checked.

A small company is selling a new board game, and they need to know how many to produce in the future. After 12 months, they sold 4 thousand games; after 18 months, they sold 7 thousand games; and after 36 months, they sold 15 thousand games. Could this information be reasonably estimated using a single linear model? If so, use the model to estimate the number of games sold after 48 months. If not, explain your reasoning.
Answer: yes and after 48 months they would sell about 16 thousand games
Step-by-step explanation:
The equation of line is y = 500x - 2000 and after 48 months , the company will sell 22,000 games
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
Let the first point be P ( 12 , 4000 )
Let the second point be Q ( 18 , 7000 )
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = ( 7000 - 4000 ) / ( 18 - 12 )
Slope m = 3000/6
Slope m = 500
Now , the equation of line is y - y₁ = m ( x - x₁ )
Substituting the values in the equation , we get
y - 4000 = 500 ( x - 12 )
On simplifying the equation , we get
y - 4000 = 500x - 6000
Adding 4000 on both sides of the equation , we get
y = 500x - 2000
Now , when x = 48 ,
y = 500 ( 48 ) - 2000
y = 22,000 games
And , Since this line's percentual error is so low, it provides a very accurate estimate of the relationship between the number of months and the number of games sold.
Hence , the equation of line is y = 500x - 2000

What is the side length of this square if the perimeter is 28 units and the area is 49 square units?
Answer:
7
Step-by-step explanation:
a square's sides are all the same length.
since the area of the square is 49 square ints,
√(49)=7.
You can check this by doing 7(4)=28, since the perimeter is 28 units, and a square has 4 sides.
