Alright! So the easiest way for me personally is to make the fraction over a number like 10 or a 100. So... for 5/20, I would multiply both numbers by 5. That gives you 25/100.

Then you could just divide.

Hope that makes sense! Let me know if you any more help!!

Answer:

x=0

Step-by-step explanation:

I must assume that your goal is to "solve for x." State your goal explicitly each time you post a problem.

Combining like terms, we get 4x = 0, so that x = 0.

Check: Is 5(0) - 13 = 0 - 13 true? YES

Paula goes to the store and buys a binder, a folder, and a highlighter. The highlighter's cost is half the cost of the binder, a

tatyana61 [14]

Answer:

Cost of the binder = $5

Cost of the highlighter = $2.5

Cost of the folder = $2

Step-by-step explanation:

Let

Cost of the binder = x

Cost of the highlighter = 1/2x

Cost of the folder = x - 3

Total cost = $9.50

Total cost = Cost of the binder + Cost of the highlighter + Cost of the folder

9.50 = (x) + (1/2x) + (x-3)

9.50 = x + 1/2x + x - 3

9.50 + 3 = x + 1/2x + x

12.50 = 2x + 1/2x

12.50 = 2 1/2x

12.50 = 5/2x

x = 12.50 ÷ 5/2

= 12.50 × 2/5

= 25/5

x = $5

Cost of the binder = x = $5

Cost of the highlighter = 1/2x = 1/2*6 = $2.5

Cost of the folder = x - 3

= 5 - 3 = $2

Amaiya purchased a box of 36 pencils to donate to Ms. Annunziata’s class, but not all pencils were used. The ratio of pencils th

deff fn [24]

15 pencils were left from the box of pencils Amaiya bought.

Step-by-step explanation:

Number of pencils in box = 36

Ratio of used pencils to not used = 7:5

Let,

7x be the total pencils used.

5x be the total pencils not used.

Therefore,

7x+5x=36

$12x=36$

Dividing both sides by 12;

$\frac{12x}{12}=\frac{36}{12}\\x=3$

Therefore,

Used pencils = 7x = 7*3 = 21

Not used pencils = 5x = 5*3 = 15

15 pencils were left from the box of pencils Amaiya bought.
