The other person did not explain so I will:
(68+79+74)= 221/3 =73.7
80 x 4 = 320
320-221 = 99
He must get 99 on his 4th test.
Thanks
Answer: 36 months
Step-by-step explanation:
total for car $26,800
down payment - <u>$ 1,600</u>
amount leased $25,200
700 monthly divided into $25,200
700/25200 = 36
Answer:
There are 14 pairs of Brand A sold.
Step-by-step explanation:
In order to find this, you need to set up a system of equations. You can set up on equation for the number sold:
A + B = 32
And you can set up one for the amount made:
30A + 35B = 1090
Now, in order to solve for the amount of A sold, multiply the first equation by -35 and add the two equations together.
-35A - 35B = -1120
30A + 35B = 1050
----------------------------
-5A = -70
A = 14
You will multiply A by 5 and B by 2.
A: 5(2x - 3y) = -6(5)
B: 2(-5x - 9y) = 15(2)
Simplify.
A: 10x - 15y = -30
B: -10x - 18y = 30
When you add down:
10x + (-10x) = 0 <--- Eliminates the x-value.
(-15y) + (-18y) = -33y
(-30) + 30 = 0
Your ending solution will be -33y = 0
Hope this helps! :)
<span>X/4 + 6 < x + 8
Step 1: Mult all terms by 4 to eliminate the fraction 1/4:
x + 24 < 4x + 32
Subtr. x from both sides; result is 24 < 3x + 32
Subtr. 32 from both sides: result is -8 < 3x, or 3x > -8, or x > -3/8</span>
