Answer:

d. y = 4 x

Step-by-step explanation:

A direct variation

1. has no y-intercept

2. has a constant positive slope.

Out of

y = 4 x + 1   [has y-intercept of +1]

y = 1/4 x       [direct variation with a slope of 1/4, not 4]

y = -4 x        [has a negative slope]

y = 4 x         [direct variation with slope of 4]

fomenos

Answer:

Bert has $45.

Step-by-step explanation:

I have no real strategy, except for that I used guess and check. How did I do this? Well, since I am in 5th Grade, I don't know algebra very well, so I made an organized chart and checked all the numbers that had to be a multiple and  could be divided equally by 5, 3 and when a third of that number was subtracted by 6, it was a fifth of the orginal number. Thats how I got 45.

Checking this answer:

It is always important to check your answer after finishing the problem, so this is how I checked my answer:

1. 45 divided by 3 = 15

2. 15 - 6 = 9, and 9 is 1/5 of 45

Bert has $45.

The distance between Dallas and Fort Worth on a map is 7.5 centimeters. The map uses a scale in which 1 centimeters represents 3
anyanavicka [17]

Hi There


To find the distance, you have to make them proportional to each other.


1 cent.  / 30 kilo. = 7.5 cent. / x


Then you cross multiply.


30 x 7.5 = x


225 = x


The distance between the two cities is 225 kilometers.


Hope that helps:)
