-8(-8+2)-4
1) Simplify <u>inside the parenthesis</u>: (-8+2)
-8(-6)-4
2) Multiply -8 and -6:
48-4
3) Simplify:
44
Answer: 
, Less
<u>Step-by-step-explanation:</u>
This year: 
Last year: 
= 
Compare this year's with last years by converting the fractions to decimals:
This year: = 0.288
Last year: = 0.300

Answer:
Its 6.45
Step-by-step explanation:
we first need to know how much is one pane of glass so i divide
15.05÷ 7 and got $2.15
so each one pane of glass is $2.15
than i multiply 2.15 x 3 and got 6.45
So the cost is 6.45
Answer:
3 Pages
Step-by-step explanation:
- Let the pages of economics read = e
- Let the pages of psychology read = p
- Let the total time taken on each instance=t
In the first instance, the student has time to read 50 pages of psychology and 10 pages of economics.
The student could read 30 pages of psychology and 70 pages of economics.
Since the two situations take the same amount of time, we have:
50p+10e=30p+70e
Collect like terms
50p-30p=70e-10e
20p=60e
Divide both sides by 20
p=3e
Therefore, in the time it will take the student to read 1 page of psychology, the student can read 3 pages of economics.
Answer:
-The equation for the problem:
Step-by-step explanation:
-First, you need determine the slope of a line:
(where 
is the first coordinate and 
is the second coordinate).
-Use both points 
and 
for the formula:
-After you have found the slope, use the point-slope formula and use the slope 
and the first coordinate, which is , to solve the equation and put it in slope-intercept form:
-Solve:
So, therefore the equation is .
