Answer:
Each person pays $12.
Step-by-step explanation:
$10 + $2 = $12
"Jeannie is 8 years older than her younger sister April"
this translates to
J = A + 8
"added together, their ages equal 198"
this translates to
A + J = 198
Plug the first equation into this one and we get
A + A + 8 = 198
add like terms
2A + 8 = 198
subtract 8 from both sides
2A = 190
divide both sides by 2
A = 190/2 = 95
Therefore April is 95 years old
the first one is 8. the second one is 18. the third one is 15.
834.39 is the answer because you take .27 and add 1 since its an increase since your working backwards to find the answer and when you get 1.27 you times that by the discounted price of 657.00 to get 834.39
Answer:
B ±sqrt((y-k)/a ) + h= x
Step-by-step explanation:
y=a(x-h)^2+k
Subtract k from each side
y-k = a(x-h)^2+k-k
y-k = a(x-h)^2
Divide by a
(y-k)/a = a(x-h)^2/a
(y-k)/a = (x-h)^2
Take the square root of each side
±sqrt((y-k)/a )= sqrt((x-h)^2)
±sqrt((y-k)/a )= (x-h)
Add h to each side
±sqrt((y-k)/a ) + h= (x-h+h)
±sqrt((y-k)/a ) + h= x
