Answer:
r = -20
Step-by-step explanation:
–7r= –8r−20

r = -20
I think you have to find the value of x and y before u can simplify it.
Mai - 6 and 3/4 is 6.75 miles
Noah - 4 and 1/2 is 4.5 miles
To find out how many times the length of Noah’s bike ride was Mai’s, you would divide so
6.75/ 4.5 = 1.5
Therefore the answer would be
b) 3/2 times as far
Answer:
2x - y = -2
Step-by-step explanation:



She earns ($9.70x40) for a 40 hour week=$388
She earned $489.85-$388 extra= $101.85
She gets paid $9.7x1.5 for every extra hour=$14.55
She worked $101.85/$14.55 hours extra=7hours
She worked 7+40 hours that week=47 hours
