Zinaida [17]

Answer:

$\dfrac{5}{6}$ hour or 50 minutes

Step-by-step explanation:

Last week:

Claire mowed 5 lawns

She mowed each lawn in $\frac{7}{12}$ hour.

She spent

$5\cdot \dfrac{7}{12}=\dfrac{35}{12}=2\dfrac{11}{12}$

hours to mow 5 lawns.

This week:

Claire mowed 5 lawns

She mowed each lawn in $\frac{5}{12}$ hour.

She spent

$5\cdot \dfrac{5}{12}=\dfrac{25}{12}=2\dfrac{1}{12}$

hours to mow 5 lawns.

Difference:

$2\dfrac{11}{12}-2\dfrac{1}{12}=\dfrac{11}{12}-\dfrac{1}{12}=\dfrac{10}{12}=\dfrac{5}{6}$

hour or 50 minutes.

2x-x+2=2-x+1
Combine like terms so
x+2=3-x
Get terms on the same side so
2x+2=3
Subtract 2
2x=1
Divide
X=1/2 or .5
