1 meter is 100 centimeters, and there are four rolls. so 4x100 equals 400, and you multiply that by the length that you didn't provide.
Answer:
30 ounces
Step-by-step explanation:
You first have to write out the two equations:
5+0.25x=y
2+0.35x=y
Then simply equal the equations to each other:
5+0.25x=2+0.35x
Subtract the 2 from both sides:
3+0.25x=0.35x
Subtract the 0.25x from both sides:
3=0.10x
Divide the 0.10 on both sides:
30=x
So, 30 ounces is your answer!
You can check by plugging 30 back into the equations to make sure that they are equal to each other.
5+0.25(30)=12.5
2+0.35(30)=12.5
Answer:
16a - 6b + 6
Step-by-step explanation:
5a + 5b - 5 + 11a - 11b + 11 = 5a + 11a + 5b - 11b - 5 + 11 = 16a - 6b + 6
Answer:
b + (-a)
