Answer:
1st one does
Step-by-step explanation:
Using proportions, it is found that $1,225 is earned from nachos.
- This question is solved by <em>proportions</em>, using a rule of three.
- The measures have an inverse relationship, hence line multiplication is applied instead of cross multiplication.
- When the theater makes $1,540 from popcorn sales, it makes $1,330 from nacho sales. How much is earned from nachos when $1,672 is earned from popcorn?
The <em>rule of three</em> is:
$1,540 - $1,330
$1,672 - $x
Applying line multiplication:



$1,225 is earned from nachos.

1) x + 3.2= -3.5
subtract 3.2 from both sides
x+ 3.2 - 3.2= -3.5 - 3.2
it cancels out on the left
x= -6.7
2) 8/9x= 32
divide both sides by 8/9
8/9x ÷ 8/9= 32 ÷ 8/9
it cancels out on the left
to divide on the right, multiply fraction by its reciprocal/inverse
x= 32 * 9/8
multiply numerators (top)
x= (32*9)/8
x= 288/8
x= 36
ANSWER: 1) x= -6.7; 2) x= 36
Hope this helps! :)
