Answer:
Step-by-step explanation:
Let's solve together :)
Solving for a.
First, add 56 to both sides to get this:
8ab+2a=−56b+6
Factor out variable "a".
a(8b+2)=−56b+6
Divide both sides by 8b+2.
a = -28b+3 / 4b+1
Have a great day. :)
Answer:
No
Step-by-step explanation:
Given that:
Total time spent exercising = 38 minutes
Walk time = 6 minutes
Run duration = (38 - 6) = 32 minutes
Running rate = 8 minutes per mile
Number of miles covered over 32 minutes :
Running rate per minute ; Miles covered per minute :
1 / 8 miles
Total Miles covered :
Rate * duration
1/8 * 32
= 4 miles
From the result above, Matteo is wrong as he will only cover 4 miles during the period.
The equations y=55x+50 and y=65x represents Rick's and Betty's trip.
Step-by-step explanation:
Given,
Head start of Rick = 50 miles
Speed of Rick = 55 mph
Let,
x be the number of hours
y be the total miles
Distance covered by Rick in x hours = Speed * Time + Head start
y = 55x + 50
Speed of Betty = 65 mph
Total miles = Speed*Time
y=65x
The equations y=55x+50 and y=65x represents Rick's and Betty's trip.
