Chemical company makes two brands of antifreeze. the first brand is
60%
pure antifreeze, and the second brand is
85%
pure antifreeze. in order to obtain
140
gallons of a mixture that contains
70%
pure antifreeze, how many gallons of each brand of antifreeze must be used?

the correct answer is 828.07

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.
