The answer is 10
The equation would look like
5(4)-4(3)+2
And if you solve it, you’ll get 10 as your answer
Answer:
8
Step-by-step explanation:
18-12
12-X
X=12*12/18
X=8mm
E. 72
6 feet long cast shadow = 24 feet pole
18 feet long cast shadow = 72 feet pole
18/6=3
24x3=72
Answer:
17.) x = 3
18.) x = -5
I couldn't do 19.) and 20.) for you because there are weird symbols that I believe you mistakenly input. But I'm sure you now get the gist of how to solve such problems. Peace <3
Step-by-step explanation:
All you really have to do for all of the problems is substitute your value of "x" for the function.
17.) f(x) = 8x - 7; f(x) =17
17 = 8x -7 ---- substitute 17 for f(x), add 7 on both sides
24 = 8x ------ divide 8 on both sides
x = 3
18.) g(x) = -4x + 7; g(x) = 27
27 = -4x + 7 substitute 27 for g(x), subtract 7 on both sides
20 = -4x
x = -5
