Answer:
2⋅18−18 is less than 2⋅[28−3⋅(2+4)]
Step-by-step explanation:
Answer:
Probably 128 km/h, but maybe 98.5 km/h. See below.
Step-by-step explanation:
What does "at the same time" mean?
If it means that he covered the 240 km in the same time as he convered the 80 km, then this is how you solve it:
80 km in 1.25 hour
240 km in 1.25 hour
Total distance: 80 km + 240 km = 320 km
Total time: 1.25 hour + 1.25 hour = 2.5 hour
average speed = (total distance)/(total time) = 320 km / 2.5 hour = 128 km/h
If it means he covered the 240 km in the same time he covered the 80 km plus the rest, then this is how you solve it:
80 km in 1.25 hour
240 km in 1.25 hour + 45 min = 240 km in 1.25 houir + 0.75 hour = 240 km in 2 hour
Total distance: 80 km + 240 km = 320 km
Total time: 1.25 hour + 2 hour = 3.25 hour
average speed = (total distance)/(total time) = 320 km / 3.25 hour = 98.5 km/h
Answer:
See attachment for graph
Or
The slope intercept form is ![y=4x+18](https://tex.z-dn.net/?f=y%3D4x%2B18)
Step-by-step explanation:
Assuming you want to graph the straight line given in point-slope form as
![y+2=4(x+5)](https://tex.z-dn.net/?f=y%2B2%3D4%28x%2B5%29)
Then we need at least two points on this line
When we compare to the point-slope formula
then we obtain (-5,-2) as a point on this line so we plot it.
When x=0, y=4(0+5)-2=18 so we plot (0,18)
We then draw a straight line through as shown in the attachment.
On the other hand, if you had wanted the equation slope intercept form, then we expand to obtain:
![y+2=4x+20](https://tex.z-dn.net/?f=y%2B2%3D4x%2B20)
![\implies y=4x+20-2](https://tex.z-dn.net/?f=%5Cimplies%20y%3D4x%2B20-2)
![\implies y=4x+18](https://tex.z-dn.net/?f=%5Cimplies%20y%3D4x%2B18)
Answer:
Cost of 18 pounds candy = $22.5
Cost of 10 pounds candy = $12.5
Cost of 1 pound of candies = $1.25
Step-by-step explanation:
6 pounds of butterscotch candies cost $7.50
⇔ 1 pound of same candy costs
$1.25
Now, we need to find the cost of 18 pounds of candy:
as, the cost of 6 pounds candy = $7.50
⇔ Cost of 6 x 3 = 18 pounds candy = $7.50 x 3 = $22.5
Cost of 10 pounds candy = 10 x (Cost of 1 pound candy)
= 10 x ($1.25) = $12.5
The unit rate for butterscotch candies = Cost of 1 pound of candies
= $1.25
Hey -- I'll answer it for you but my vision is not that great... Could you just type the question in a reply, or DM it to me? Sorry, it's just really small on the picture, even when I tried to zoom it in.
