Answer:
Step-by-step explanation:
y - 72 = 8(y - 3)
Distribute the 8 into (y - 3).
y - 72 = 8y - 24
Subtract 8y from both sides.
-7y - 72 = -24
Add 72 to both sides.
-7y = 48
Divide both sides by -7.
y = -48/7 or approxametly -6.9.
Proof:
y - 72 = 8(y - 3)
Substitute variable.
-48/7 - 72 = 8(-48/7 - 3)
Subtract.
-552/7 = 8(-69/7)
Multiply 8 by the inside term -69/7.
-552/7 = -552/7.
Answer: The square root of 18 divided by square root of 50 is 5 square root of x divided by 5.
Answer:
1. 10x + 14
2. 2x + 11y - 7
3. -10x - 11
Step-by-step explanation:
1.
2.
3.
4/5. 4/5 is the correct answer
Multiply by 4 on both sides. This results into:
24 = a + 8
If 8 is substracted in both sides then a would be:
16 = a
