What is the value of a in the equation 5a - 10b = 45, when b = 3?

a=15

5a−10b=45 , when b=3

Substitute the value of b into the equation.

5a−10(3)=45

Solve for a.

5a−10(3)=45

5a−30=45

5a=75

a=15

What is the value of a in the equation 5a – 10b = 45, when b = 3?

3

15

21

39

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.

.25 times 180= 45

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
