This is the concept of proportionality, we are required to calculate for the number of hours two crews can use to paint the house altogether.
Here proceed as follows;
number of hours new crew can paint=12 hrs
portion of work painted by new crew in 1 hour= 1/12

number of hours experienced crew can paint=6 hours
Portion of work painted by experienced crew in 1 hour=1/6

Portion of work painted by the two crews altogether in 1 hour will be:
1/6+1/12=1/4

thus the total amount of hours that the two painters will take to paint will be:
4 hours

Solve for y 4.2x - 1.4y = 2.1
NeX [460]
4.2x - 1.4y = 2.1
-1.4y = -4.2x + 2.1
y = (-4.2/-1.4)x + 2.1/-1.4
y = 3x - 1.5 <==

What is the slope intercept of y/2-4=x/3
Ierofanga [76]

Answer:

Step-by-step explanation:

y/2 - 4 = x/3 can also be written as 1/2y - 4 = 1/3x

slope intercept form is y = mx + b

1/2y - 4 = 1/3x....multiply entire equation by 6, to get rid of fractions

3y - 24 = 2x ...add 24 to both sides

3y = 2x + 24....divide both sides by 3

y = 2/3x + 6 <===
