James is running late to his cousin's wedding and drives the 45 miles between his house and the wedding location 20 miles per ho
netineya [11]

Answer:

(r + 20)t = r

Step-by-step explanation:

Distance is constant in the scenario above, distance from home to wedding and wedding back home is the same.

From wedding back home. :

Recall : Distance = speed * time

Distance = r * 1 hour

From home to wedding :

Speed = 20 mph more ; r + 20

Time = t

Distance = (r + 20)* t = (r +20)t

Since the distance are the same, we can equate both :

(r + 20)t = r * 1

= (r + 20)t = r

Carl spent $140 in six days. He spent $20 on the first day. He spent the same amount of money during the next five days. 4a.Writ
expeople1 [14]

Answer:

20 + 5m = 140

$24 on each day of the last five days

Step-by-step explanation:

Total amount to spend in 6 days = $140

He spent:

First day = $20

Balance = Total amount to spend - Amount spent on first day

= $140 - $20

= $120

He spent the same amount of money during the next five days.

Amount spent each day in the last 5 days = Balance / 5 days

= 120 / 5

= 24

Amount spent each day in the last 5 days = $24

The equation is

20 + 5m = 140

Where,

m = amount spent in the last five days

20 + 5m = 140

5m = 140 - 20

5m = 120

m = 120 / 5

m = $24
