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.

It is shown as a sum of each digit multiplied by its matching place value<span> (units, tens, hundreds, etc.) For example: 4,265 = </span>4<span> x 1,000 + 2 x 100 + 6 x 10 + 5 x 1.</span>
Answer:
x = 36.45
Step-by-step explanation:
set up equation
2x + 8.8 = 81.7
subtract 8.8 from both sides
2x = 72.9
divide 2 from both sides
x = 36.45
For infinitely many solutions, you must get each side of the equation to equal itself. So solve the first equation: 7 - 5 + 3x - 1
2 + 3x - 1
1 + 3x
Now make the blanks 3x and 1. For no solution, you can have anything other than x = an integer or x itself. If x = 2 + x, then it will have no solution. We have the solved equation: 1 + 3x. Fill in the blanks with 3x + any integer other than 1. For one solution, make it so x equals an integer. For example, you could fill in the blanks with 2x + 4, or anything other than 3x + 1 or 3x + any integer other than 1.
