katovenus [111]

Answer:

C

Step-by-step explanation:

3y - 5x = 15 ... A

y = 5/3 * X +15 .... slope 3/5 , y intercept 15

6y - 10x =30

(6y - 10x) /2 = 30 / 2

3y - 5x = 15 ... B

y = 5/3 * x + 15 ..... slope 3/5 , y intercept 15

∴ Answer is C

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 .
