Let's solve by eliminating
x
. Since 18 is the lowest common multiple , let's multiply the first equation by 3 and the second by -2.
Add the two equations.
Divide by -11 to isolate
y
y= -2
Substitute
y
=
−
2
into either of the 2 equations, I'll just use the second one.
x = -1

Step-by-step explanation:
To find the total number of carbohydrates, you need to find what fraction 6 is of 100, so you can do 100/6, but I just did 18* 100/6 right away, so that you can find 18* the fraction that 6 is of 100. The answer that I got is 300 grams. Hope this helps!
Answer:
Total number of painters = 25 painters
Step-by-step explanation:
Interior painting = 10 painters
These painters made up 40% of the painting crew
how many painters in all worked on this job?
Let
Total number of painters = x
Interior painters = 40% of x
10 = 40% * x
10 = 0.4 * x
10 = 0.4x
x = 10/0.4
x = 25 painters
Total number of painters = x = 25 painters
