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: 199.5
Step-by-step explanation: 9.5 x 10.5 hours x 2 weeks
My guess would be x = -30
Hello from MrBillDoesMath!
Answer:
32 ft^2
Discussion:
You solved it yourself. The area of a parallelogram of base "b" and height (altitude) "h" is b*h. In this case
Area = 8 * 4 = 32 ft^2
Thank you,
MrB
13 feet
Pythagorus is used
25 + 144 = 169
169 is 13 to the second power etc
