Distance=amount of gas times miles per gallon
distance=y
amount of gas=x
mpg=?
given
y=300
x=10
300=10 times ?
divide both sidesj by 10
30=?
equation is
y=x times 30 or
y=30x
Answer:
D. All of the above
Step-by-step explanation:
A is right, 3(g) = 3g
I don't know about b, but c is right, so it is all of the above
They have to pay the 30$ fee first then it depends on how many people are coming with you
Well, what's the diffrence from 5/4 to 3/8?
![\bf \cfrac{5}{4}-\cfrac{3}{8}\qquad \stackrel{\textit{LCD is 8 clearly}}{\implies }\qquad \cfrac{10-3}{8}\implies \cfrac{7}{8}](https://tex.z-dn.net/?f=%5Cbf%20%5Ccfrac%7B5%7D%7B4%7D-%5Ccfrac%7B3%7D%7B8%7D%5Cqquad%20%5Cstackrel%7B%5Ctextit%7BLCD%20is%208%20clearly%7D%7D%7B%5Cimplies%20%7D%5Cqquad%20%5Ccfrac%7B10-3%7D%7B8%7D%5Cimplies%20%5Ccfrac%7B7%7D%7B8%7D)
so, if we take 5/4 to be the 100%, what is 7/8 off of it in percentage anyway?
Answer:
The constant of proportionality is option D i.e 5.
Step-by-step explanation:
Variation:
Variation problems involve fairly simple relationships or formulas, involving one variable being equal to one term. There are two types of variation i.e.
- Direct variation
- Inverse variation
Direct Variation:
Mathematical relationship between two variables that can be expressed by an equation in which one variable is equal to a constant times the other.
Example ![y=kx](https://tex.z-dn.net/?f=y%3Dkx)
where, k is constant of proportionality.
The above given example is of Direct Variation
∴ y = 5 x
∴ k = 5 = constant of proportionality.
Inverse Variation:
Mathematical relationship between two variables which can be expressed by an equation in which the product of two variables is equal to a constant.
Example ![yx=k](https://tex.z-dn.net/?f=yx%3Dk)
where, k is constant of proportionality.
