1. Sarah and Maya both need notebooks and pencils. The equation that represents Sarah's
purchases is y = 13- 3x. The equation that represents Maya's purchases is y = 7 -x. If y
represents the price of notebooks, and x represents the price of pencils, what are the prices of
the notebooks and pencils?
a) pencils: $4 notebook: $3 go to card 4
b) pencils: $6 notebook: $1 go to card 3
c) pencils: $3 notebook: $4 go to card 5
d) pencils: $1 notebook: $6 go to card 7
e) pencils: $4 notebook: $4 go to card 2
Answers
Step-by-step explanation:
We have y = 13 - 3x and y = 7 - x.
=> 13 - 3x = 7 - x
=> 2x = 6, x = 3.
Then y = 7 - (3), y = 4.
Hence the price of a pencil is $3 and the price of a notebook is $4. (C)
answer is c) pencils: $3 notebook: $4 go to card 5
solve for x in the following question 2x - 3 = 1
Answers
Answer:
x = 2
Step-by-step explanation:
2x-3 = 1

2x = 4
use division property of equality (divide both sides by 2)
4/2 = 2
so,
x = 2
Please mark me brainliest, and I really hope you have a great day!
2x - 3 + 3 = 1 + 3
2x = 4
2x/2 = 4/2
X = 2
So, in conclusion, X is equal to 2.
