Answer:y= -2x/3 + 2
Step-by-step explanation:
ANSWER:
As they are alternate exterior angles, so they must be equal.
8x + 13 = 12x + 7
8x - 12x = 7 - 13
- 4x = - 6
x = 3/2.
Answer:
Isolate one variable in one of the equations and substituting it into the other equation. *note* in example the first substitution is given to you
Step-by-step explanation:
For example:
-3x-4y=-2
y=2x-5
Substitute -4y with second equation
-3x-4(2x-5)=-2
PEMDAS
-3x-8x+20=-2
-11x+20=-2
Subtract 20 on both sides of the = sign
-11x=-22
Divide both sides
x=2
Plug that into the second equation
y=2(2)-5
y=4-5
y=-1
Answer:
The parking rate at the hospital a parking garage are 50 cents for the 1st hour and 25 cents for each additional hour if guan part in the hospital parking garage for 8 hours how much will the total of charge for parking be
I always had trouble doing percents, but my last algebra teacher taught me an easy way, where you turn the percent into a decimal.
Maria: to find 25% of 26.50, you multiply 26.50 by 0.25 to get 6.625. now, you subtract 6.625 from 26.50 to get 19.875. which would round to 19.88$. To find the 10% sales tax, you multiply 19.88 by 0.10 or 0.1 to get 1.988. that would round to 2.00. She would then add 19.88 and 2.00 to get 21.88$.
Edwin: I am not even sure how to figure out Edwin's math, his is not even comprehendible for me.
When I'm shopping, I always use Maria's method to figure out the price of things, therefore, I am 99% sure she is correct and Edwin is not. If it said that they both came with 23$, and the price of the book is now only 21.88, then yes, they have enough money to purchase the book.
and sorry this took long, I'm multitasking.
