What value of x makes this equation true?

Mathematics

Alex73 [517]3 years ago
4 0

Answer:

x=9/4=2.25

Step-by-step explanation:

The model is essentially saying:

3(-x)+10(1)=5(x)+8(-1)

Simplify:

-3x+10=5x-8

Subtract 5x from both sides:

-8x+10=-8

Subtract 10 from both sides:

-8x=-18

Divide both sides by -8. The negatives cancel:

x=18/8

Reduce:

x=9/4=2.25

And we're done!

Doss [256]
Let P be the number of kids,
we know P>57
take 1-(1/2)-(1/5)=3/10
therefore 57 is 3/10P
3/7P=57
P=57*7/3=133 is the answer
it would be incorrect if we didnt get a positive integer.
