Answer asapA football team lost 9 yards on its first play. It then gained 9 yards on its second play.


Explain A. What expression can be written to represent how many yards the football team is from where it started? Explain your reasoning.

Explain B. How many yards is the football team from where it started?

Explain C. Suppose that, instead, the football team had gained 9 yards on its first play and lost 9 yards on its second play. Would the team’s position on the field have been any different than it actually was after the first two plays? Why or why not

Answers

for A:  Do -9+9.  It is negative because they LOST yards,  which means backwards momentum xDD
For B:  They are right where they started.  -9+9=0.  They lost 9,  then gained the 9 they had lost.
C:  It would not have been different.  No matter what way you add it,  it would have been the same thing.  Instead it would be 9-9,  which is still 0.

How to solve mp-5p when m=-4 and p=2

Answers

You can substitute in the values. So m=-4 so put that in instead of m. And p=2 so put that in instead of p.
The problem is then (-4)(2)-5(2). Simplify to -8-10 And your final answer is -18. Wasnt aware you could edit these after you made them haha. I did correct my math in my comments riaght after the post. Sorry about that guys ^.^
so everyone knows, xy means x times y, not the digits themselves

so mp-5p
subsitute -4 for m and 2 for p
(-4)(2)-[(5)(2)]
-8-[10]
-18

Need help please, thanks! A map has a scale of 1 inch:18 kilometers.

Three distances on the map are listed in the chart below. Drag an actual distance into each box to match the corresponding distance on the map.

0.8 in.___________________

1.4 in.____________________

2.1 in.____________________


I don't know, please explain! :(

Answers

Given:
1 inch : 18 kilometers

Let us use the ratio and proportion method:

a:b = c:d where ad = bc

0.8 inches is 14.4 kilometers

1 : 18 = 0.8 : x
x = 0.8 * 18
x = 14.4 km

1.4 inches is 25.2 kilometers

1: 18 = 1.4 : x
x = 18 * 1.4
x = 25.2 km

2.1 inches is 37.8 kilometers

1 : 18 = 2.1 : x
x = 18 * 2.1
x = 37.8 km
