1 yard = 3 feet
So you simply simplify 7\3 which is 2 1\3
So 7 ft. = 2 1\3 yards
Answer:
a = 12 years
Step-by-step explanation:
Mark is 6 years older than his brother Sam. Now, we are asked to represent Sam’s age by a. This means that if Sam is a years old, Mark is (a + 6) years old.
The sum of their ages is 30, this means that when we add their ages together, we get the sum of thirty.
Mathematically this means a + a + 6 = 30
2a + 6 = 30
This is the equation needed to get a. To get a , we proceed to solve the equation to completion.
2a = 30 - 6
2a = 24
a = 24/2
a = 12

Answer:
x=−4y+10
Step-by-step explanation:
Let's solve for x.
−x−4y=−10
Step 1: Add 4y to both sides.
−x−4y+4y=−10+4y
−x=4y−10
Step 2: Divide both sides by -1.
