Question

Can someone help please thank you

Answer 1

Answer:

The length of a pencil is 4.5 inches. The length of a crayon is 2.1 inches.

Step-by-step explanation:

Let pencils be p

Let crayons be c

6 pencils and 5 crayons are 37.5 inches. This will be:

6p + 5c = 37.5 ........ equation 1

7 pencils and 6 crayons are 44.1 inches. This will be:

7p + 6c = 44.1 ........ equation 2

Multiply equation 1 by 7

Multiply equation 2 by 6

42p + 35c = 262.5 (3)

42p + 36c = 264.6 (4)

Subtract 4 from 3

c = 2.1

Plug the value of c into equation 1

From equation 1

6p + 5c = 37.5

6p + 5(2.1) = 37.5

6p + 10.5 = 37.5

6p = 37.5- 10.5

6p = 27

p = 27/6

p = 4.5

hope this helps
