Matthew threw 55 pitches in a baseball game. Of those pitches, 4/5 were strikes.
zlopas [31]
Hi there! The answer is 44.

To find our answer we have to multiply 55 by 4/5. Then we get the following:

55 \times \frac{4}{5} = \frac{55}{1} \times \frac{4}{5} = \frac{220}{5} = 44

Therefore, 44 of Matthew's pitches were strikes.

Answer:

Step-by-step explanation:

Putting values of x in equation

Y = 4(-3) - 4

= - 12 - 4 = - 16

Y = 4(-2) - 4

= - 8 - 4 = - 12

Y = 4(-1) - 4

= - 4 - 4 = - 8

Y = 4(0) - 4

= 0 - 4 = - 4

Y = 4(1) - 4

= 4 - 4 = 0

Y = 4(2) - 4

= 8 - 4 = 4

Y = 4(3) - 4

= 12 - 4 = 8
