Answer:
Leah has 15 stickers left.
Step-by-step explanation:
The total number of stickers that Leah had was 50. Leah gave 1/2 of the stickers to her sister. This means that the number of stickers that Leah gave to her sister was: 1/2 × 50 = <u>25 stickers</u>
.
Of the amount left, she gave 2/5 to her brother. This means that the number of stickers that Leah her brother was
: 2/5 × 25 = <u>10 stickers
</u>.
Therefore, the number of stickers that Leah have left for herself is
:
50 - (25 + 15)
= 50 - 35
= <u>15 stickers</u>
I hope this helps you!
Have a great day! :)
The constant of the proportional relationship graphed in this problem is of 10.
<h3>What is a proportional relationship?</h3>
A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:
y = kx
In which k is the constant of proportionality.
In this problem, the points on the graph are: (0,0), (2,20), (4,40), ..., hence the constant is:
k = 40/4 = 20/2 = 10.
