Answer:
C
Step-by-step explanation:
to get to 18 from 15, you add three.
You keep adding three to every number for the y values since it it a linear function. The x values went up by 1 and the y values went up by 3.
It would be three feet. Hope this helps.
The monthly salary = $1130 plus 10% commission from the sells
The sales of the last month = $37,200
so, the amount of commission = 10% of 37,200 =

So, the gross pay = 1,130 + 3,720 = $4,850
A is the concentration of the first container, B the second container.
300a+600b=900·(15)=13500
1.3a+6b=135
100a+500b=600·(12.5)=7500
2.a+5b=75
Multiply eq. 2 by (-3) and add to eq. 1 to eliminate A.
3a+6b-3a-15b=135-225
-9b=-90
b=10
Then from eq. 2,
a+50=75
a=25
The first container is a 25% solution and the second container is a 10% solution
Answer:
The area of the trapezoid:
A = (base1 + base2) x height/2
= (6 + 12) x 8/2
= 18 x 4
= 72
Hope this helps!
