Answer:
x=2
Step-by-step explanation:
In order to solve this problem, you need to find the scale factor. This is done through cross multiplying proportions. In this instance, you have to cross multiply x/4 by 3.5/7. When you multiply x and 7, you get 7x. When you multiply 3.5 and 4, you get 14. Simplify by isolating the variable, and you get 2.
when you add two negatives its just like regular number, -3+-5=-8 same as 3+5=8
2 hours = 45 pages
1 hour = 45 ÷ 2 = 22.5 pages
12 hours = 22.5 x 12 = 270 pages
Answer; 270 pages
-2x + 8 = -4x + 1
- 1 -2x
7 = -6x
—
-6x
7/-6 or -7/6
Answer:
y = 2/5 x - 3/5
Step-by-step explanation:
2x = 5y + 3
Rewrite
5y + 3 = 2x
Subtract 3 from both sides
5y = 2x - 3
Divide both sides by 5
y = 2/5 x - 3/5
