you need to add for number one you need to subtract for number two you need to add for number 3 you need to subtract for number 4
7x - 3y = 24
7x - 24 = 3y
(7x - 24) : 3 = y
Total ratio = 4+7 = 11
33/11 = 3
4x3 = 12
7x3 = 21
so the two groups are 12:21
which is also = 4:7
therefore, the Correct choice is d) 15
Answer:
1.5x=6
x=4
Step-by-step explanation:
The area is length times width so 1.5 times x is the correct equation. Make x equal to one by dividing both sides by 1.5. x=6/1.5. Simplify this to get x=4.
