On Sunday, 370 people bought tickets to the county fair. Tickets cost $7 for adults and $3 for children. The total revenue from
STALIN [3.7K]
Number of child tickets: x
Number of adult tickets: y

1) x+y=370
2) 3x+7y=1750

Using the method of substitution
a) Isolating y in the first equation:
1) x+y=370→x+y-x=370-x→y=370-x

b) Replacing y=370-x in the second equation:
2) 3x+7y=1750→3x+7(370-x)=1750

c) Solving for x: Distributive property:
3x+7(370)-7x=1750
3x+2590-7x=1750

Adding similar terms:
-4x+2590=1750

-4x+2590-2590=1750-2590
-4x=-840

Dividing both sides of the equation by -4:
-4x/(-4)=-840/(-4)
x=210

Replacing x=210 in the first equation:
1) y=370-x→y=370-210→y=160

Answer:
The number of child tickets was 210 and
the number of adult tickets was 160

John withdraws $40.00 from her savings account each month. What integer represents the net effect on her balance after 5 months?
lina2011 [118]

Answer:

The net effect of amount in John account after 5 months is  $A - $200

Step-by-step explanation:

Given as :

The amount of money withdraws by John each month from his account = $40

Let The total amount of  money did John had in his account = $A

Let the amount left in John account after 5 months of withdraw = $x

<u>So, According to question</u>

∵ Each month the money withdraw from account = $40

∴ In 5 months , the money withdraw = $40 × 5

I.e In 5 months , the money withdraw = $200

So, The left money in account after withdraw in 5 months = $A - The amount withdraw in 5 months

I.e x = $A - $200

So, The balance in account after 5 months = x =  $A - $200

Hence, The net effect of amount in John account after 5 months is             $A - $200  Answer

Simplify (1/4 ad^3)^2
Dima020 [189]
That "ad^3" bothers me; I'm not sure what you mean here.

I'm going to assume that you have     (1/4*a*d^3)^2.

If that's the case, then you have (1/4)^2 * a^2 * d^6 = (1/16)*a^2*d^6.

If this is not what you were hoping for, double check to ensure that you have copied down this problem exactly as it was presented.
