Answer:
Hot dogs - 27, soda - 81
Step-by-step explanation:
Soda to Hot dog ratio = 3:1
If the total is 108, we can divide 108/4 ---> 27
now, multiply 3 and 1 by 27 and there you go!
edit: also if you don't know why I divided 108 by 4, its because you add together both sides of the ratio
Answer:
y = -32
Step-by-step explanation:
-6 (y+15) = -3y + 6
-6y - 90 = -3y + 6
-3y - 90 = 6 + 90
= -3 = 96
y = -32
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx
so
That means it's the equation of a line passing through the origin.
case a) and case d) are discarded because the line does not pass through the origin
<u>case b) we have</u>
for x=2 y=4
y/x=k-------> 4/2=2------> k=2
y=2x-------> in this case the value of y is two times the value of x
<u>case c) we have</u>
for x=4 y=2
y/x=k-------> 2/4=1/2------> k=(1/2)
y=(1/2)x-------> in this case the value of y is one-half of the value of x
therefore
the solution is the case c) see the attached figure

Answer:
- Cameron is 13 and Avery is 8 years old
Step-by-step explanation:
Let Cameron's age be x and Avery's age be y.
<u>The difference is 5 and the product is 104:</u>
<u>Solve by substitution:</u>
- xy = 104
- y(y + 5) = 104
- y² + 5y - 104 = 0
- y = (- 5 ± √(5² + 4*104))/2 = (- 5 ± √441)/2 = ( - 5 ± 21)/2
<u>Taking the positive root as age can't be negative:</u>
<u>Find x:</u>
