Giovanna used the calculations below to determine the height of a stack of 7 books that are each 2 and StartFraction 5 over 8 En
cluponka [151]

Answer:

She didn't do the multiplication of 7 times the fraction 5/8 by using distributive property.

so the correct answer is the one that looks like:

Seven was not multiplied by StartFraction 5 over 8 EndFraction.

in your list of options.

Step-by-step explanation:

If one has a stack of seven books each 2\frac{5}{8} \,\,in thick, one should first convert the mixed number to an addition of an integer plus a fraction

2\frac{5}{8} =(2+\frac{5}{8})

as she did, and then multiply 7 by the addition, making sure to use distributive property and multiply both terms:

7\,\,(2+\frac{5}{8})=7\,*\,12+7\,*\,\frac{5}{8}=14+\frac{35}{8}

and she didn't do the multiplication of 7 times the fraction 5/8

Find the value of x:
nadya68 [22]

Answer:

x = 3

Step-by-step explanation:

These angles are vertical angles. Vertical angles equals to on another but on the opposite side. Since they equal to another you do:

(10x + 1) = (12x - 5)

Add 5 on both sides:

10x + 6 = 12x

Subtract 10x on both sides:

6 = 2x

Divide 2 on both sides:

3 = x
