Answer:
A) f=8 8/9
Step-by-step explanation:
f+2/9=9 1/9
f+2/9=82/9
f=82/9-2/9
f=80/9
f=8 8/9
Answer: C
|x+5| = 7 (Spilt into 2 problems)
X+5=7
X+5=-7
Solve for x on both
x=2 and x=-12
60 seconds * 1.30 = 78. 78 seconds * 1.5 = 117 seconds.
117+78+60= 225 seconds.
225 seconds is your answer! :)
Hopefully this helped!
The answer is 18. The two sides are the same length, so you set the two sides equal to each other and solve for x. After finding x, you plug in the number into the base expression and you get the base length.
