Step-by-step explanation:
Hello there.
Question: <span>Mr. Nicolas is putting up strings of blue and white lights for the holidays. The ratio of blue to white lights is 5 to 6. If he has 77 strings, how many strings are white lights?
Answer: 5:6
Add the numbers:
5 + 6 = 11
Divide this number by the total:
77/11 = 7
Multiply values by this number:
5 x 7 = 35
6 x 7 = 42
To check:
35 + 42 = 77.
Therefore your answer is 42.

Simplify 7x + 2y = -23
Solving
7x + 2y = -23
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation.
7x + 2y + -2y = -23 + -2y
Combine like terms: 2y + -2y = 0
7x + 0 = -23 + -2y
7x = -23 + -2y
Divide each side by '7'.
x = -3.285714286 + -0.2857142857y
Simplifying
x = -3.285714286 + -0.2857142857y
7+d=19 is the answer
subtract 7 from each side d=19-7
d=12
