Well first you would start by setting up with a proportion.
In total, the girls paid $54+$22= $76
Thus 1 sister contributed $54/$76=x/100
The other sister contributed $22/$76=x/76
For each proportion, cross-multiply and simplify to get the percentage. The percentage will be the x

You and your sister bought your mom a gift.
You paid $54 and your sister paid $22.
Because 54 + 22 = $76, the gift cost a total of $76.

To figure out what percentage each sister paid, you divide what they paid by the total cost.

Thus, because you paid $54, the percentage of the gift that you bought is 54/76 ≈ 0.71 = 71%

Therefore, because your sister paid $22, the percentage of the gift that she bought is 22/76 ≈ 0.29 = 29%

You bought 71% of the gift and your sister bought 29% of the gift.

We need to get a common denominator of 10

-1/2 *5/5 = -5/10

2/5*2/2 = 4/10

-5/10 +4/10 = -1/10

Which ordered pair would form a proportional relationship with the point graphed below?
jolli1 [7]

Answer:

(5, 20)  

Step-by-step explanation:

We can find the slope of the line

m = (y2-y1)/(x2-x1)

    = (40-0)/(10-0)

    = 40/10

    =4

Since the line goes through (0,0) the y intercept is 0

y = mx+b

y = 4x

Lets check the points  by substituting into the equation

40, 10)     10 = 4*40   10 =160  no

(–5, –10)    -10 = 4*-5    10 = -20   no

(5, 20)       20 = 4*5    20 = 20  yes

(–10, –20)    -20 = 4*-10    -20 = -40   no
