His answer works ... it gives 150, which is the same as (60 + 90) ... but he didn't deliver exactly what the problem asked for.

It asked for the <u>GCF</u> to be outside the parentheses, and he put  '3'  there.

'3'  is certainly one common factor of 60 and 90, but it's far from being the
greatest one. 

The GCF  of 60 and 90 is actually  30 .  So the absolutely positively technically correct response to the instructions in the problem would be  30(2 + 3).

The most likely number of bags of peanuts she

sold is 20 bags of peanut at at $4 each

<h3>Equation</h3>

Kiyo:

94 = 10 + x

94 - 10 = x

84 = x

Aleja

94 = 14 + y

94 - 14 = y

80 = y

  • Find the highest common factor of 84 and 80

80 = 1, 2, 4, 5, 8, 10, 16, 20, 40 and 80.

84 = 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42 and 84

  • The highest common factor is 4

80 ÷ 4 = 20 bags of peanut

84 ÷ 4 = 21 bags of peanut

masha68 [24]

We have been given that Grant spent $2.50, $4.00, $4.25, and $3.25 on breakfast in one week. The next week he spent $6 more in total for the 4 breakfasts than the week before. We are asked to find increase in the mean of second week.  

Since Grant spent $6 more than last week, we will divide 6 by 4 to get how much mean of second week breakfast expenditures increased with respect to first week expenditures.

\text{Mean increase in second week breakfast expenditure}=\frac{6}{4}

\text{Mean increase in second week breakfast expenditure}=1.5

Therefore, mean of second week breakfast expenditure will be $1.5 more than first week.
