M is correct, at the end your answer will be 5m
All you have to do here is replace f(x) with x + 2 and h(x) with 1/x-1.
It's like plugging in a number for x, but instead you are plugging in a whole function instead of just a number. Whenever you are pluging something in, whatever it is, make sure it is in parentheses: ( ) always!
Until your understanding of algebra becomes stronger.
2f(x)-hx
First lets plug in x + 2 for f(x). It's gonna look like this:
2(x + 2) - h(x)
Notice how I put x + 2 in parentheses next to the 2, you
a l w a y s want to do this. Now we just do the same for h(x):
2(x + 2) - (1/x - 1)
And that's it. That's all you have to do.
Answer:
8.8
Because you can devide 66 by 7.5
Step-by-step explanation:
Answer:
27 t-shirts
Step-by-step explanation:
First, set up an equation. Using T as the unknown number of t-shirts, we see:
50 + 3T = 131
3T = 81
T=27 t-shirts
Hope that helps!
(2.75 x 10⁵ ) / (2.25 x 10² )
= (2.75 / 2.25) x 10⁵⁻²
= 1.2 x 10³ times .
(That's 1,200 times as many.)
