Answer:
x = 5
y = 4
Step-by-step explanation:
1. 2x + 2y = 18
2. x + 3y = 17
Multiply the first equation by 1 and the second equation by 2 to eliminate x
We have
2x + 2y = 18
2x + 6y = 34
Subtract equation 2 from equation 1
-4y = -16
Divide both sides by -4 to isolate y
-4y/-4 = -16/-4
y = 4
Now substitute 4 for y in either equation to get x. Using equation 2 we have
x + 3y = 17
x + 3 x 4 = 17
x + 12 = 17
Subtract 12 from both sides
x + 12 - 12 = 17 - 12
x = 5
x = 5 and
y = 4
Answer:

Step-by-step explanation:
Area is the width (6/7 yd) multiplied by the height (1 yd).
6/7 x 1 = 6/7 
a=6, b=2
Step-by-step explanation:
Use simplification into substitution



We can now plug this value of <em>a</em> into the second equation.

Get rid of fractions in the numerators and/or denominators

Then we can match the denominators

Combine

Divide both sides by three

Get rid of fractions

Single out <em>b</em>


Now we can plug it into the equation



Now we can check it;

Answer:
8,935,200 minutes
Step-by-step explanation:
24x60 is 1440 (minutes in one day)
1440x365 is 525,600 (minutes in one whole year)
525,600x17 is 8,935,200 (minutes in 17 years)
