Answer:
u=50
Step-by-step explanation:
the angles of a triangle must add up to 180 degrees so set up the equation:
180=(u+48)+(u-14)+(u-4)
180=3u+30
150=3u
u=50
Answer:
Singer A tours made $226 million.
Singer B tours made $200 million.
Step-by-step explanation:
If Singer be made x million then Singer B made x - 26 million .
Total made = $426 million so
x + x - 26 = 426
2x = 426 + 26 = 452
x = $226 million for Singer A.
Singer B made 426 - 226
= $200 million.
So 5 1/2 pages in 12 minutes
rewrite as eleven/2
Make a proportion
pages over minutes = pages over minutes
in an hour, there are 60 minutes
11/2 / 12 = x / 60
cross multiply
(11/2 * 60) = 12x
330 = 12x
divide both sides by 12
27.5 = x
She will read 27.5 pages in an hour.
How many pages in 3 hours?
that is 60 * 3 minutes
180 minutes
Use the proportion of pages/minutes = pages/minutes
plug in what you are given
<span>11/2 / 12 = x / 180
Cross multiply
(11/2 * 180) = 12x
990 = 12x
divide both sides by 12
82.5 = x
She will read 82.5, or 82 1/2, pages in 3 hours (or 180 minutes ;) )
Hope this helps </span>
The answer would be f = -7 for the question.
f (-1) = 4 (-1) + 11
