Answer: a=36; b=18
Step-by-step explanation:
1. You know that the sum of two numbers is 54, then, you have:
a+b=54
2. According to the problem, the larger number is 18 more than the sampler number, this can be expressed as following:
a=b+18
3. Then, you must substitute the second equation into the first equation and solve for b:
b+18+b=54
b=18
4. Then the value of a is:
a+18=55
a=36
Since they are working together, you need to add the 5 hours and 3 hours together which if 8 hours.
Then you need to divide the 8 hours to 2.
The answer is 4 hours if Jay and David paint a house together.
5 * 3
= 8
8/2
=4
I hope my answer helped you.
Have a great day!
Plot a point at the y-intercept of -2 or y = -2
--------------------------------------------------------------------
From there make a straight horizontal line
---------------------------------------------------------------
Then Shade the upper-half of that line one color This shaded part stands for
Y > -2
-----------------------------------------------------------------------
Shade the lower half a different color, this stands for y ≤ 6
-------------------------------------------------------------------------
That should be it!
