Answer:
a=1
Step-by-step explanation:
7(5a-4)-1=14-8a
Distribute
35a - 28 -1 = 14 -8a
Combine like terms
35a -29 = 14 -8a
Add 8a to each side
35a+8a -29 = 14 -8a+8a
43a -29 = 14
Add 29 to each side
43a -29+29 = 14+29
43a = 43
Divide each side by 43
43a/43 = 43/43
a =1
Answer:
x=-3/5y+3
Step-by-step explanation:
Let's solve for x.
5x+3y=15
Step 1: Add -3y to both sides.
5x+3y+−3y=15+−3y
5x=−3y+15
Step 2: Divide both sides by 5.
5x/5 = -3y+15/5
Answer
x=-3/5y+3
Answer:
Step-by-step explanation:
The length can be found by setting up a proportion. If the width is reduced by some ratio, then the length will share the same ratio.
3 / 8 = x / 10 Multiply both sides by 10.
3 * 10 / 8 = x Multiply first
30/8 = x Divide next. You don't need to do it in this order.
3 6/8 Simplify
3 3/4 Give another choice
3.75
The length = 3.75 inches
If none of these are correct, please leave a note with your choices.
