An American football team is on their own 35-yard line they lose 5 yards on each of the next three plays at what yard are they now

Answers

If they lose 5 yards on each of the three plays, that would be -15. 35 - 15 will give you 20 (unless they are on the opposite side, which then will give you 50 yards).
Dang, those must've been horrible plays.

the answer is 5×3-35 would be 5x3=15 35 -15=20

PLS HELP 1. The expression 0.08x+(x−200) models the final price of a computer with an instant rebate in a state that charges a sales tax.

Enter the expression in the box that represents the amount of tax that is paid on the computer.

2.The expression 937(1+x) gives the markup price of a computer, where x is the percent of the markup written in decimal form.

Which part of the expression represents the percent, in decimal form, of the initial price that is being paid?

Enter your answer in the box.

Answers

Answer:

#1) 0.08x; #2) (1+x)

Step-by-step explanation:

#1) 0.08 is read as 8 hundredths. This can also be written as 8/100. Percent means out of 100; this means 8/100 is 8%. This means 0.08x is taking 8% of the original amount; this would represent the sales tax that is paid.

#2) In this problem, x is the percent of markup written in decimal form. This means that adding 1 to this number gives us 100% plus the percent of markup. This will give us the percentage of the original price that was paid, since we are paying 100% of the original price plus the markup.

Hippalectryon Points U, V, and W are plotted on a number line. The coordinate of point V is –2. Points U and W are the same distance from point V.

What could be the coordinates of U and W?

A.
U = –11, W = 7

B.
U = –8, W = –6

C.
U = –6, W = 6

D.
U = 0, W = 2

Answers

Checking answer A:
distance from U to V = -2-(-11)=9
distance from U to W =7-(-2)=9 -> same distance !

checking answer B:
distance U-V : -2-(-8)=6
U-W : -2-(-6)=4 -> not the same distance

answer C :
U-V : -2-(-6)=4
U-W : 6-(-2)=8 -> not the same distance

answer D :
U-V : 0-(-2)=2
U-W : 2-(-2)=4 -> not the same distance

Conclusion : answer A

D. 0, 20 is 2 away for -22 is 4 away from -2
C -6, 6-6 is 4 away from -26 is 8 away from -2
You have to find out which two points are the same distance from -2.

Can someone help me please!!!!!1.Grace and Allie are going to meet at the fountain near their houses.They both leave their houses at the same time. Allie passes Grace's house on her way to the fountain.
* Allie's walking rate is 2 meters per second.,* Grace's walking rate is 1.5 meters per second.
A-How many seconds will it take Allie to reach the fountain.
b-Suppose Grace's house is 90 meters from the fountain. Who will reach the fountain first,Allie or Grace explain why.

Answers

Well, if the fountain is 90 meters from the fountain, to find Allie's distance, simply divide 2 by 90.
90/2 = 45

It will take Allie about 45 seconds to reach the fountain.

Obviously, Allie will reach the fountain first because she is walking more meters per second.
