Answer: 90.2
Reasoning: You add all grades together. Next you dived by 5 because their are 5 grades. You then revive an average of 90.2
Answer: Divide distance by speed to get time.
Speed and time are inversely proportional. As speed increases, time decreases.
Distance = speed × time So distance is the the constant of variation.
Step-by-step explanation: Divide distance by speed to get time.
180km÷50km/h = 3.6h by Car
180km÷45km/h = 4h by Bus
180km÷40km/h = 4.5h by Truck
180km÷25km/h = 7,2h by Bicycle
Answer: 15
Step-by-step explanation:
6/5 x 3/3 =18/15
GIVEN: y = 3x + 5
--> slope of given line = 3
--> This means that your equation must have the same slope, or "m"
FORMULA OF A LINE: y = mx + b
--> Use point-slope form to find "b"
POINT SLOPE FORM: y - y₁ = m ( x - x₁ )
--> Plug in your given point AND the slope of the given line
y - 5 = 3 ( x - 4 )
y - 5 = 3x - 12
y = 3x - 7

ANSWER: y = 3x - 7</h3>
Answer:
the answer is y=8.5x
Step-by-step explanation:
because x would equal the hours and y would equal the money.
so you divide y by x, so in this case it would be 127.50/15 and that equals 8.5
so the multiplier or constant of proportionality, if thats what you guys call it, is 8.5.
