Answer:
9 7/12
Step-by-step explanation:
12 is a suitable common denominator.
(7 3/4) + (1 5/6) = (7 9/12) + (1 10/12) = (7+1) +(9/12 +10/12)
= 8 + 19/12 = 9 + 7/12 . . . . . . change 19/12 to 1 7/12
= 9 7/12

Answer:
0.7475
Step-by-step explanation:
A suitable calculator can show the area under the curve is 0.7475.
$25 per item sold + $100 per week = 700 total goal in 1 week
X is our items sold variable. We only use 100 since our goal is for only one week.
25x + 100 = 700
Subtract 100 from each side.
25x = 600
Divide by 25.
x = 24

Answer by stanbon(75887)
Step-by-step explanation:
You can multiply either the top or bottom equation by -1 so lets say you apply it to the bottom equation it’ll look like this:
-9x + 9y = 18
6x - 9y = 12
then the +9y and -9y will cancel out
-9x = 18
6x =12
then you add the two equations together
-3x = 30
divide both sides by -3
x = -10
