Someone please help me !!

Step-by-step explanation:

s=b×h/2

h=3.3

s=3.3b/2

s=22.4

22.4=3.3b/2

22.4(2)=3.3b

3.3b=44.8

divide both sides by 3.3

b=44.8/3.3

b=13.57

to the nearest tenths

b=13.6

a=c×h

h=10

c=x

a=10x

a=59.7

59.7=10x

divide both sides by 10

x=59.7/10

x=5.97

to the nearest tenths

x=6

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
