The decimal equivalent of 1/4 is 0.25.
The concept that is useful to answering the question above is the ratio -proportion. Let x be the number of white paint that should be used in the mixture. The ratio - proportion expression of the given above is ,
5 parts / 2 parts = 8.5 quarts / x quarts
Solving for x gives an answer of x = 3.4. Thus, 3.4 quarts of white paint should be used for the mixture.
Answer:
x = 7
Step-by-step explanation:
A triangle's total interior angle measurement will equal 180°.
Set all measurements equal to 180:
(82) + (9x - 6) + (6x - 1) = 180
Simplify. Combine like terms:
(82 - 6 - 1) + (9x + 6x) = 180
(82 - 7) + (15x) = 180
(75) + 15x = 180
Next, isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and stands for:
Parenthesis
Exponents (& Roots)
Multiplication
Division

First, Subtract 75 from both sides of the equation:
15x + 75 = 180
15x + 75 (-75) = 180 (-75)
15x = 180 - 75
15x = 105
Next, divide 15 from both sides of the equation:
(15x)/15 = (105)/15
x = 105/15
x = 7
7 is your value for x.
