This situation can be represented by
y = 33x + 223
y = 32x + 239
I still like substitution, so let’s plug in 33x + 223 into the second equation
33x + 223 = 32x + 239
Move the terms into appropriate sides
33x - 32x = 239 - 223
Combine like terms
x = 16
Then plug in x for any equation
y = 32(16) + 239
y = 751
Erin will have to swim 16 laps for a total of 751 meters
Given:
A figure.
To find:
The values of x and y.
Solution:
We know that, in a right angled triangle,



Multiply both sides by 16.


And,



Multiply both sides by 16.


Therefore, the missing side lengths are
and

Jane walked a quarter of the distance she walked on Monday, so that means she walked 4 times less hoped this helped. :]
12 months in a year
2300/12
we can round 2300 to 2400 (because it is an estimate) and divide by 12 to give an approximation of $200 each month
