Answer:
A. Simon's unit rate is 2 more miles per hour than Eric's unit rate
Step-by-step explanation:
We are concerned with the number of miles each runs in 1 hour.
For Eric, that means x=1 in his equation, so his mileage is ...
y = 6×1 = 6 . . . . miles
__
For Simon, it means we want to find time = 1 hour on the horizontal axis at the bottom of the graph. Then we want to see where the graphed line crosses that vertical line. The point of crossing has horizontal line that goes over to 8 on the vertical distance axis. That is, Simon runs 8 miles in 1 hour.
__
Eric's unit rate (miles in 1 hour) is 6 miles per hour.
Simon's unit rate (miles in 1 hour) is 8 miles per hour.
Simon's unit rate is 2 more miles per hour than Eric's unit rate.
Answer:
the first one must be 39.5 and the other 42.5
Step-by-step explanation:
multiply 35 by 6 and subtract 32 x 4 you are left with 82. Divide that by 2 and make the difference 3.
Answer:
The options are not shown, so i will answer in a general way.
Let's define the variables:
h = number of hats
m = number of mugs.
We know that a total of 1000 items were ordered, then:
h + m = 1000
We also know that we have 3 times more mugs than hats, this can be written as:
m = 3*h
Now we have the system of equations:
h + m = 1000
m = 3*h
To solve these, we usually start by isolating one of the variables in one equation and then replace that in the other equation, but in this case, we already have m isolated in the second equation, then we can replace that in the first equation to get:
h + m = 1000
h + (3*h) = 1000
Now we can solve this equation for h, and find the number of hats ordered.
4*h = 1000
h = 1000/4 = 250
There were 250 hats ordered.
