Answer:
Step-by-step explanation:
This system of equations is convenient, because the second equation already expresses y in terms of x. Now, you can substitute that in.
Multiplying both sides by -1 and bringing the 5 over:
Combining like terms and factoring out 5:

Answer:
She should start making the batter at 1:17 p.m.
Step-by-step explanation:
The cake will take 46 minutes to bake. Subtract that time from 2:41 p.m to get 1:55 p.m. Subtract 38 minutes from that to get 1:17p.m. That is the answer I got. Good luck :)
Answer:
2.) 48 Inches
Step-by-step explanation:
Mean = average so to find the average you add all the numbers together and divide by the number of subjects there are so -
49 + 47 + 46 + 45 + 53 = 240
240 ÷ 5 = 48 in
have a good day! :)
x = -2
y = 1
let's multiply second equation by 4 to get a common coefficient of y variable.
16x-8y=-40
add the equations
3×+8y=2
16x-8y=-40
----------------
3x+16x = -38
19x = -38
x = -2
substitute x
3×-2 + 8y = 2
-6 + 8y = 2
8y = 2+6
y = 1
check the answer
-6+8 = 2
-8-2= -20
I believe the answer is -4 3/4 meters
Because if she is 2 1/4 above and it drops -2 1/2 below you add
