Answer:
8
4 --
11
Step-by-step explanation:
The gear ratio for the original gear system was 4/22. To get the 22 inch wheel to 26 inches, you have to multiply it by 26/22, so to keep the same ratio, you will also need to multiply 4 by 26/22. You get 104/22, which simplifies to 52/11 which simplified further to 4+8/11. You can check your answer by comparing the original ratio to the new ratio.
Answer : 3m^6-12m^5-14m^4+15m^3-12m^2-6
Answer:
B
Step-by-step explanation:
Given
(4x² - 3x - 4) - (3x² + 4x - 8) ← distribute by - 1
= 4x² - 3x - 4 - 3x² - 4x + 8 ← collect like terms
= x² - 7x + 4 → B
Answer:
x = 29
y = 13
Step-by-step explanation:
Write 2 equations:
x + y = 42
x - y = 16
Isolate x in the first equation:
x = 42 - y
Substitute this in for x in the second equation:
42 - y - y = 16
42 - 2y = 16
solve for y:
-2y = -26
y = 13
Plug in 13 for y in either equation:
x + 13 = 42
Solve for x:
x = 29
