Answer:
(-3, -4).
Step-by-step explanation:
-4x + y = 8
x - 5y = 17 Multiply this by 4:
4x - 20y = 68 Add this to the first equation:
-19y = 76
y = 76/-19
y = -4.
Plug this into the second equation:
x - 5(-4) = 17
x = 17 - 20
x = -3.
CHECK this result in equation 1:
-4(-3) + -4 = 8
12 - 4 = 8
8 = 8 <------ OK.
Answer:
She will not meet her goal.
Step-by-step explanation:
There are 5 weekdays, so she will run for 0.5 * 5 = 2.5 hours over the weekdays
There are 2 weekends, so she will run for 2 * 1 = 2 hours over the weekend.
In total, this means she will run for 4.5 hours.
4.5 hours * 550 calories per hour = 2475 calories.
She will not meet her goal.
