360/18=20
So, your answer is 20 unit rate.
Hope this will help you!
(2/5)+(3/(5x))=(x+5)/10
nasty fractions, we hates it forever
so
get rid of all those nasty fractions
multiply both sides by 10x
4x+6=x(x+5)
distribute
4x+6=x^2+5x
minus (4x+6) from both sides
0=x^2+x-6
factor
0=(x-2)(x+3)
set each to zero
0=x-2
2=x
0=x+3
-3=x
x=-3 and 2
3rd option is answer
Answer:
The middle number would be (14+15)/2 = 14.5
How I found that is I did (14+15)/2.
pls mark as branliest
I always prefer factoring, if there are simple factors.
There are simple factors here.
x² + 11x + 18 = 0
(x + 2) (x + 9) = 0
The left side is zero if either factor is zero.
First factor:
x + 2 = 0
<u>x = -2</u>
Second factor:
x + 9 = 0
<u>x = -9 </u>
the answer is 75 minutes/1h 15m
15 pages × 350 words = 5250 words
5250 ÷ 70 = 75 minutes (1h 15m)
hope this helps!!
