Answer:
its the second one
Step-by-step explanation:
Answer:
x=-1
Step-by-step explanation:
x − 7 = 46 − 9(x + 7)
distribute
x-7 = 46 - 9x -63
Combine like terms
x-7 = -9x-17
Add 9x to each sid
x-7+9x = -9x+9x -17
10x-7 = -17
Add 7 to each side
10x -7+7 = -17+7
10x = -10
10x/10 = -10/10
x = -1
As you can see, this is a multiplication root.
y = 4 · x
x = 7 · 3
So solve for x first to solve for y.
x = 7 × 3
x = 21
y = 4 · x
y = 4 × (21)
y = 84
She can write 3/8 of a page in 1 minute.
basically, she writes 1/8 of page in 1/3 of a minute. So, that means she can write 1/4 of a page in 2/3 of a minute.
1/4 + 1/8 = 3/8.
I really hope this makes sense to you.......sorry I'm not that great at explaining it.
