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.

I'll give you the linear equation:

y = mx + b ; where m is the slope of the line ; b is the y-intercept.

y = -5x - 2

m = -5
b = -2

-5 is the slope of the line while -2 is the y-intercept. Choice 1.) -5

Answer:

-5

Step-by-step explanation:

because -5 is the answer and it is choice 1 i didi quiz and -5 is good answer

What would the answer for X be ??

Answers

Answer:

140°

Step-by-step explanation:

The external angle is half the difference between the intercepted arcs. One arc is shown as 30°. The other will be the difference between 180° and (30°+x). Then we have ...

(30 -(180 -(30+x)))/2 = 10

x -120 = 20 . . . . . . . multiply by 2 and simplify

x = 140 . . . . . . . . . . . add 120

The measure of arc X is 140°.

Plz help i beg i will give 20 points and give brainlist ALEX tried to find the value of x. FIND HIS ERROR AND CORRECT IT.

Answers

it’s a 90 degree angle. So the equation so be 28+2x =90 and find x from there.

28+2x=90
-28 -28
2x= 62
x=31

His error was he put 180 rather than 90 because it’s and acute angle so the number you minus by would be 90 done and then you finish the equation like he did
