The number is 84. If you find numbers that equal 12 that are both one digit numbers, you have 9 and 3, 8 and 4, and 7 and 5. If you put 48, together they equal 12. If you divide 84 by 7, you will get 12. 84 reversed is 48, which is 4 times 12. So if you times 84 by 4/7, you will get 48.
<span>So, the formula for this problem is 10/x =40/64. You can solve for x by cross multiplication so, you end up with 40x=640 with x=16. So Justin should charge his friend $16.00.</span>
Answer:
D
Step-by-step explanation:
a⁶ - b⁶
(a³)² - (b³)²
(a³ - b³)(a³ + b³)
[(a - b)(a² + ab + b²)][(a + b)(a² - ab + b²)]
(a - b)²(a² + ab + b²)(a² - ab + b²)
The slope is -5. Find two lattice points (points with integer coordinates) and find (y1-y2)/(x1-x2) with the two points being (x1,y1) and (x2,y2). The equation would be

, or -5.
Answer:
x=22, y=45
Step-by-step explanation:
y=45 by definition (180-90)/2
180 = 46 + 2x
x = 22
