x + y = -9
x + 2y = -25
Rewrite the first equation as x = -9-y
Relace x in the second equation:
-9-y + 2y = -25
Simplify:
-9 +y = -25
Add 9 to both sides:
y = -16
Now you know y,, replace y in the first equation and solve for x:
x -16 = -9
Add 16 to both sides:
x = 7
Answer: x = 7
It would take him four and a half days, or you could round it up to five if that's what you need. Either way, he would then have 3/4 of the fence done
Answer:
Step-by-step explanation:
Given
per copy
Solving (a): Linear Equation
The total charges (y) is: the base charge + the rate * number of copies (x).
So, we have:
<em>The 0.44 is 44 cents converted to dollars</em>
Solving (b): Purchase if he budgets $76.16
This implies that y = 76.16
So, we have:
Collect like terms
Solve for x
Answer:
C) 6 inches
Step-by-step explanation:
(√72)² = x² + x²
72 = 2x²
72/2 = x²
36 = x²
√36 = √x²
6 = x
x = 6 inches
