Remember pemdas

First simplify the expression -3(2x)+5x=-9

Next multiply -3•2x=-6x
Now the expression is -6x+5x=-9

Add the alike variables it would be the same as 6x-5x now u just have x

X=-9

Hope that helps and u should download Photomath it helps a lot

Answer:

$1017.19

Step-by-step explanation:

First find the fraction of how much of Paulo's money is spent on his rent and car. Add 1/4 and 1/8, which is 3/8 because 1/4 = 2/8. Then multiply 3/8 by Paulo's monthly spending, which is $2712.50. Multiplying those numbers will get you $1017.1875. which you have to round up to $1017.19 because you can't spend three quarters of a cent.

Answer:

Let R be the greater radius and r be the smaller radius

A) Area of the sidewalk = R^2 - r^2   - This can be the expression

B)  = 3.14

=(R^2-r^2)

=(11^2-9^2)

=(121-81)

=*40

That was the simplified expression

Answer = 3.14 * 40 = 125.6m^2

An angle is 26.2° more than its complementary angle what is the measure of each angle
Mila [183]

Answer:

58.1 and 31.9 degrees

Step-by-step explanation:

x + other angle = 90 because complementary angles add up to 90

x = the angle

x = 26.2 more than the other angle

subtract 26.2 from both sides

x - 26.2 = other angle

x + other angle = 90

plug x - 26.2 for other angle

x + (x-26.2) = 90

2x - 26.2 = 90

add 26.2 to both sides to isolate the variable and its coefficient

2x = 116.2

divide both sides by 2 to find x

x = 58.1

other angle = x - 26.2 = 31.9
