X = 7
The angles are congruent so you’d do, 4x-5=23 and you’d get x = 7
Answer:
5040
Step-by-step explanation:
-1 × -2 × -3 × -4 × -5 × -6 × -7 × -8 = 40320
40320 ÷ 8 = 5040
(not 100% sure this is right)
The formulas:
Expand the expression:
Plug the values into the expression:
Answer:
g(x)=5x+7
Step-by-step explanation:
f(x)+g(x)=9x+4
We are given f(x)=4x-3.
So we insert 4x-3 for f:
4x-3+g(x)=9x+4
Subtract 4x on both sides:
-3+g(x)=5x+4
Add 3 on both sides:
g(x)=5x+7
Check:
f(x)+g(x)
=(4x-3)+(5x+7)
=(4x+5x)+(-3+7)
=(9x) +(4)
=9x+4
Bingo. We did it! :)
Answer:
not really
Step-by-step explanation:
The number of friends (x) is expected to be an integer. 6.5 friends does not really make sense.
_____
There are all kinds of ways this might make sense, but none of them are supported by the information given in the problem statement.
