Afootball team received 2 penalties for 15 yards each, 7 penalties for 5 yards each and 1 penalty for 19 yards. write and find the value of an expression to the change in the field position from those penalties

-84 yards

Step-by-step explanation:

The football team receiving a penalty will have negative number of yards.

For the first penalty, they received two 15 yard.

Total yards = 2(-15)

= -30 yards

For the second penalty , they received seven five yards

the total yards= 7(-5)

= -35 yards

for the last penalty, they received one 19 yards

Total yards= 1(-19)

= -19 yards

x= -30 + (-35) + (-19)

x = -30-35-19

x = -84 yards

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
