Answer:
10w ≥ 30
Step-by-step explanation:
First, the variable w represents the "sum of a number and 15", so we don't know the missing value. Therefore the first part is 10w. The inequality is ≥ because it represents "at least 30". Your inequality should be 10w ≥ 30
Hope this helps!
F(g(x)) where you see an 'x' in f(x) put a g:
f(g(x)) = 1/(g-7), now step by step: g - 7 = 6/x+7-7=6/x, and 1/(g-7)=1/(6/x)=x/6!
I let the second one for you. Sorry if you disagree!
1. A) 19 ; 2. B) 5,5 ; 3. D) 10
There are 16 glasses, 7 are large and the rest are small
Since we assume the rest are small:
16 glasses - 7 glasses = 9 glasses left
Therefore 9 glasses are small
x^4-2 I think, because you can add your exponents, then you subtract them when you divide, then you just take 2 / -1.
