So, Mary Lou took\frac{5}{6} of an hour, that is \frac{5}{6}*60 mins=50 mins

Heather took \frac{9}{10} as much time as Mary Lou, so she took \frac{9}{10} of 50 minutes, that is \frac{9}{10}*50=45

45 minutes is less than 50, so Heather was faster and Mary Lou was slower and took longer!

after x + 1 / 3 - x + 2 / 2x have been combined using the least common denominator of 6x, what is the numerator?
olganol [36]
Answer: The numerator will be 2x^2 - x - 6.

For the first fraction, we need to multiply it by 2x. So we will have:

2x(x + 1) = 2x^2 + 2x

For the second fraction, we need to multiply it by 3. So we will have:
3(x + 2) = 3x + 6

Now, we just have to subtract the numerators.
2x^2 + 2x - 3x - 6
2x^2 - x - 6

Solve the equation 4 x - 6 = 6- 2x​
Greeley [361]

Answer:

x=2

Step-by-step explanation:

4x-6=6-2x

(add 2x and 6 to both sides)

6x=12

(divide by six)

x=2

Double Check:

4(2)-6=2

6-2(2)=2

4(2)-6=6-2(2)
