Tom is going to the fair in town and wants to eat lunch. A hot dog costs 2$ and a cheeseburger costs 3$.write an equation that represents the possible combinations of how many of each he can buy for 10$

Let's define the variables:

x = number of hot dogs he buys

y = number of cheeseburgers he buys.

Each hot dog costs $2, then the price of x hotdogs is:

x*$2

Each cheeseburger costs $3, then the price of y cheeseburgers is:

y*$3

The total price is:

x*$2 + y*$3

And we want to find an equation to see how much he can buy for exactly $10, then we have:

x*$2 + y*$3 = $10

Or, if he can use $10 or less than $10, the inequality would be:

$0 ≤ x*$2 + y*$3 ≤ $10

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."

they go with it happens or they mite give a chance?
