Answer:
3x+4=y
x+y=32
Step-by-step explanation:
x= magazine book price
y=history book price
you need to multiply the price of the magazine by 3 and add 4 to get the price of the history book, 3x+4=y.

Step-by-step explanation:
L / 240 = C / 2π
Your answer is x = 7 – 2y
Answer:
(-2, 3)
Step-by-step explanation:
<u>Substitute 2x + 7 for y in y = -2x - 1</u>
- <u></u>

Add 2x to both sides
Subtract 7 from both sides.
Divide both sides by 4.
<u>Substitute -2 for x in y = 2x + 7</u>
- <u></u>

Simplify both sides.
Therefore, the answer is (-2, 3).

Answer: 2.18 kilometres
Step-by-step explanation:
First we take down the information given to us
Maria's house to library (distance) = 3.56 km
Simon's house to library (distance) = 1.38 km
Now to get how farther Maria lived from the library compared to Simon, we subtract the distance between the library and Simon's house from the distance between the library and Maria's house
i.e
3.46km - 1.38km = 2.18km
there for Maria lived 2.18 kilometres farther from the library compared to Simon.
