R =
I think “represent” is asking you to solve to a number.
10r + 4 = 8
Subtract 4 from both sides of the equation:
10r = 4
Divide both sides by 10:
r = 0.4
Check the math:
10(0.4) + 4 =
4 + 4 = 8
Answer:
(A) 10
Step-by-step explanation:
Let age of Marco's be "x" years
then according to question
Yolanda age will be "2x - 5"
Also in the question it is given that age Yolanda is 15 years.
then, 2x - 5 = 15
Adding 5 both sides of the equation, we will get
2x = 20
Dividing both sides of the equality by 2, we get
x = 10
therefore, Age of Marcus will be 10years
Option (A) is the correct option.
47. 12388980384689 would be the exact circumference of a circle witha diameter of 15 inches :)
<span>3x - 5 < 4.
Add 5 to both sides,
3x < 9
Divide 3 from both sides,
x < 3
Hope this helps!</span>
Cody because 18 out of 20 is %90 and 24 out of 30 is %80
