I am not good in this kind of question so maybe 84?

suppose the full marks for each of them is 100 so for 5 of them it will be 500 cause if you if you multiply 100 full marks by 5 it will be 500

so the answer to this question is maybe 84?

cause if you add all of them with 84 the outcome will be 400 and if you divide the 400 by 5 it will be 80

zmey [24]

Answer:

3 pencils

Step-by-step explanation:

We are given Zayed is helping his classmates get ready for their math test by making them identical packages of pencils and calculators.

Number of pencils=72

Number of calculators=24

If Zayed creates the greatest number of identical packages

Then , we find GCF of 72 and 24

$72=2\times 2\times 2\times 3\times 3$

$24=2\times 2\times 2\times 3$

GCF= $2\times 2\times 2\times 3$

Hence, Zayed creates 24 packages.

Number of pencils in each package= $\frac{72}{24}=3$

Hence, 3 pencils and one calculator will be in each package .

Answer:

22x + 100 = 25x + 70, 10 yards

Step-by-step explanation:

Set the number of square yards of carpeting as x.

So, the cost of Country Carpets is: 22 * x + 100

And the cost of City Carpets is: 25 * x + 70.

In order for the costs to be the , the equations need to be equal.

22x + 100 = 25x + 70

Subtract 22x from both sides.

100 = 3x + 70

Subtract 70 from both sides.

3x = 30

x = 10

10 square yards
