Serena wants to solve the following system of equations in the most efficient way.
Marianna [84]

Answer:

Serina should have solved for x in the second equation because it has a coefficient of 1.

Step-by-step explanation:

we have

2x+3y=18 ----> equation A

x+7y=31 ---> equation B

we know that

To solve the system of equations in the most efficient way, solve for x equation B and then substitute the value of x in equation A

so

x=31-7y ----> equation C

substitute equation C in equation A

2(31-7y)+3y=18

solve for y

62-14y+3y=18\\11y=62-18\\11y=44\\y=4

Find the  value of x

substitute the value of y in the equation C

x=31-7(4)=3

The solution is (3,4)

therefore

Serina should have solved for x in the second equation because it has a coefficient of 1.

Let d(t) be the total number of miles Joanna has cycled, and let t represent the number of hours after stopping for a break duri
katrin [286]
For this case we have the following equation:
 d (t) = 12t + 20

 The variables are:
 t: time in hours
 d (t): distance traveled in miles.
 We evaluate the distance traveled after 4 hours.
 So we have that for t = 4:
 d (4) = 12 (4) +20

d (4) = 48 + 20

d (4) = 68
 Answer:
 
d (4) = 68
 
This means that after 4 hours Joanna cycled for 68 miles total
