PLS I NEED THIS ASAP I WILL GIVE BRAINLIEST TO WHOEVER ANSWERS CORRECT!! 100 points to whover answer correctly with good explanation for a 7th grader Working together, two ants named Aran and Beatrice can build an ant hill
in 10 hours. Aran and Charlie can build the ant hill in 12 hours. Beatrice
and Charlie can build the ant hill in 15 hours. How long, in hours, will it
take to build the ant hill if Aran, Beatrice, and Charlie work together?

They complete the hill in 8 hours

Step-by-step explanation:

We will need to solve these equations with a system of equations, so we need to isolate one variable in one of the equations and then replace it with another equation. After this, this means that Beatrice alone would construct the hill in 24 hours and Charlie 40. So, after finding the value A we will need to add A with B and C. This would get us . We will then divide  . This will leave with 8h.

A= 7/120h

C=1/40h

B= 1/24h

yes

step-by-step explanation:

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
