The list that shows all the factors pairs of 30 is A
Answer:
$80 per T.V.
Step-by-step explanation:
First you want to multiply 25 by 19, the amount of televisions sold with an extended warranty.
Next you want to subtract that amount from the total earnings, this way you can find out the amount he earned in total from selling 19 televisions without their warranty.
After that divide that number by 19 to find out how much each television was worth each.
In the proportional theory,
28 units is the total measurement that includes 8 units.
So, 10 + 3x - 5 is the total measurement that includes 10 units proportionally.
This means,
28 = 10 + 3x - 5
Now solve for x,
28 = 10 + 3x - 5
28 - 10 = 3x - 5
18 + 5 = 3x
23 = 3x
23 / 3 = x
So x = 23/3 or 7.6666....
Answer:
b = 4
r = 3
Step-by-step explanation:
r + b = 7
solve for 'r' to get r = 7-b
now substitute '7-b' for r in the second equation:
3.75(7-b) + 2.75b = 22.25
26.25 - 3.75b + 2.75b = 22.25
-b = -4
b = 4
r = 3
