Answer:
x=36
y=6
Step-by-step explanation:
Let the numbers be x and y
Condition 1
x=6y ----------(1)
Condition 2
x-y=30 ------------(2)
Putting 1 in 2
6y-y=30
5y=30
Dividing both sides by 5
y=6
Now
Putting y=6 in 1
We get
x=6(6)
x=36
Answer:
C
Step-by-step explanation:
3x + 3y = -x + 5y
3x + x = 5y - 3y
4x = 2y
Divide both by 2
2x = y
(1,2) when x=1, y=2
2(1)=2 is a true statement
(2,4) when x=2, y=4
2(2)=4 is a true statement
2.5 yards is $15 so you divide 15 by 2.5 and you would get the cost of each yard, which is $6 per yard :)
