Answer:
Distributive
Step-by-step explanation:
You distribute the 5 into 3x+18, multiplying it by each part of the equation (each part is separated by one of these signs: +, -, x, or /) to get 15x (from 5 x 3x) plus 60 (from 5 x 18).
Work out the top subtraction first:
3/9 - 8/12
= 1/3 - 2/3
= 1/3
and the bottom part:-
3/8 * 2 = 6/8 = 3/4
so now we divide -1/3 by 3/4
= -1/3 * 4/3 = -4/9
Answer:
The answer is 21.10
Explanation:
If her bill in July was $52.75 and her bill in August was only 60% of July
60% of 52.75 is 31.65
and they asked how much more she paid:
52.75-31.65 = 21.10
hope this helps!
Answer: 378
-------------------------------------
-------------------------------------
Work Shown:
f(x) = x^2 - 3x
f(x) = ( x )^2 - 3*( x )
f(-18) = ( -18 )^2 - 3*( -18 ) ... replace every x with -18; now use PEMDAS
f(-18) = 324 - 3*( -18 )
f(-18) = 324 + 54
f(-18) = 378
