Answer:
-7.2
Step-by-step explanation:
Since -3.2 is the first number, this will be the starting point in the number line.
Since we are subtracting, we are going to go 4 units to the left.
-3.2 - 4 = -7.2
Best of Luck!
Answer: Plot a point at (-6,5) then just go start up. That is your graph

Answer:
- 64 gallons 30%
- 96 gallons 55%
Step-by-step explanation:
The amount of each brand can be found by writing and solving an equation that makes use of the given relations.
<h3>Setup</h3>
Let x represent the quantity of 55% pure antifreeze needed in the mixture. Then the quantity of the 30% brand is (160-x). The amount of pure antifreeze in the mixture is ...
0.55x +0.30(160 -x) = 0.45(160)
<h3>Solution</h3>
Subtracting 0.30(160), we have ...
x(0.55 -0.30) = 160(0.45 -0.30)
x = 24/0.25 = 96 . . . . . simplify, divide by the coefficient of x
96 gallons of the 55% brand, and 64 gallons of the 30% brand must be used.
