Step-by-step explanation:
what is the problem ? this is very straight forward with a calculator :
cos(64°) = y/8
y = 8×cos(64°) = 8×0.438371147... = 3.506969174... ≈
≈ 3.5
Step-by-step explanation:
given

as equation 1, and

as equation 2.
Now, multiply equation 2 by 2.

now let's this equation be equation 3.
We now use equation 1 + equation 3 to eliminate y and find x.

Now substitute x = 7 into equation 2.

Given that the ski club sold 42 Italian hoagies and 53 roast beef hoagies, they sold a total of 95 hoagies. The ratio of Italian hoagies to total number of hoagies sold is obtain by dividing 42 by 95. Mathematically,
ratio = 42 / 95
Answer:
Step-by-step explanation:
25x = 300
Rearrange to solve
x = 300 divided by 25 = 12
