A chemical company makes two brands of antifreeze. The first brand is 70% pure antifreeze, and the second brand is 95% pure anti
Paul [167]
Let a be the amount needed of 70% pure antifreeze, and let b be the amount needed of 95% pure antifreeze.
0.7a + 0.95b = 180 * 0.9 .........(1)
a + b = 180 .............................(2)
b = 180 - a ..............................(3)
Plugging the expression for b in equation (3) into equation (1), we get:
0.7a + 0.95(180 - a) = 162 ......(4)
Solving equation (4) gives the value a = 36, and plugging this value for a into equation (2) we get b = 144.
Amounts needed are therefore 36 gallons of 70% pure antifreeze and 144 gallons of 95% pure antifreeze.

Answer:

Q1. 20x = 200. The value of x is 10

Q2. 7 - 3x = 1. The value of x is 2.

Step-by-step explanation:

In order to find an equation, you have to let the number be any variable, such as m or n or z. So I will let the number be <em>x variable</em>. Then the question says a number is multiplied by 20 is equals to 200 :

Let number = x,

x \times 20 = 200

20x = 200

20x \div 20 = 200 \div 20

x = 10

Same for the next question. Given that a number multiplied by 3 :

Let number = x,

x \times 3 = 3x

Then subtracted by 7 equals to 1 :

7 - 3x = 1

7 - 3x - 7 = 1 - 7

- 3x =  - 6

- 3x \div  - 3 =  - 6 \div  - 3

x = 2
