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

Step-by-step explanation:
Area of a triangle
The area of a triangle can be calculated using the formula
A = bh/2 where b = base length and h = height
Finding the area by plugging in the values of the height and base length
Looking at the triangle we can tell that the base length is 8 and the height is 10. ( so b = 8 and h = 10 )
So we have A = bh/2
==> plug in b = 8 and h = 10
A = (8)(10)/2
==> multiply 8 and 10
A = 80/2
==> divide 80 by 2
A = 40
