Answer:
T = 4B + 10C
Step-by-step explanation:
Since there are 4 doughnuts in a bag then there are 4B doughnuts in B bags
Since there are 10 doughnuts in a carton then there are 10C doughnuts in C cartons, thus summing the two quantities gives
T = 4B + 10C
Answer:
Graph: Refer to attached image
Solution: (-5,-3)
Step-by-step explanation:
First graph to two equations.
Refer to the image attached to see what the equations would look like when graphed.
Wherever they intersect is the solution.
They intersect at (-5,-3) therefore (-5,-3) is the solution to the system of equations
Sub
105=700*0.05*t
105=35t
divide both sides by 35
3=t
t=3
Answer: -7x-6
Step-by-step explanation:
Multiply the number of packages by the mean. Then subtract the two totals:
400 x 4 = 1600
500 x 5 = 2500
weight of 5th package = 2500 - 1600 = 900kg
answer: 900 kg
