Need to attach graph for me to answer.
Answer:
4
Step-by-step explanation:
4d + 1 = 17
1 + 4d = 17
Move all terms containing d to the left, all other terms to the right.
1 + -1 + 4d = 17 + -1
0 + 4d = 17 + -1
4d = 17 + -1
4d = 16
d = 4
Answer:
the cost of each book = $24
Step-by-step explanation:
(if all the books have the same price)
Let x be the price of one book
“She had $157 and After buying 6 books ,she was left with 13$“ means
“157 = 6x + 13”
now we have an equation to solve :
157 = 6x + 13
⇔ 157 - 13 = 6x
⇔ 144 = 6x
⇔ 24 = x
I believe the answer is A.
i think it is 27 i did 5+4 then i did 9x3 and got 27
