Solve this PLZ!<br> 4 - 7 (v - 9) = -7 -6(v - 10)
Arisa [49]
I maybe wrong, but I think it is 14

Simplify both sides of the equation
(Do distributive property)
Add 6v to both sides
Subtract 67 from both sides
Divide both sides by -1

Answer: Plane AEF

Step-by-step explanation: Parallel means equal or same as. If you follow the letters BCD you can see that it sorta makes a triangle shape. So if you follow the answer choices you could see that AEF is the only one that does what BCD does if that makes sense :)

suppose you have $55 in your bank account. You start saving $10 each week. Your friend has $20 in her account and is saving $15
zhenek [66]
The equation is:
55 + 10 x = 20 + 15 x, where x is number of the weeks.
55 - 20 = 15 x - 5 x
35 = 5 x
x = 35 : 5
x = 7
Answer:
The same amount of money in both accounts will be after 7 weeks.
