Answer:
57 tickets
Step-by-step explanation:
This is because 650-200= 450 and 450/8 is 56.25
so round the answer up and you get 57
Answer:
(exact 56.25) rounded, more realistic 57 tickets
Step-by-step explanation:
650 total
650-200=450 this is the price removing the 200 as the starting investment.
450÷8 = 56.25 people would need to buy movie tickets.
since there can not be 0.25 of a ticket then, a rounded 57 people would have to buy tickets and they would have 456$
they only need 450 (56.25×8) so they have an extra 6 dollars to buy KitKats and candy or something.

Help me find Z in the diagram
Answer:
z=68°
Step-by-step explanation:
z is congruent to the given angle
hopefully this helps :)
Answer:
z = 56°
Step-by-step explanation:
Since the 2 sides are congruent then the triangle is isosceles, thus
The base angles are congruent, then
z = [tex]\frac{180-68}{2}[/tex] = [tex]\frac{112}{2}[/tex] = 56°
simplify 6-12b divided by 3a-6ab
Answer:
[tex]\frac{2}{a}[/tex]
Step-by-step explanation:
Given
[tex]\frac{6-12b}{3a-6ab}[/tex] ← factor both numerator and denominator
= [tex]\frac{6(1-2b)}{3a(1-2b)}[/tex] ← cancel common factor (1 - 2b) on numerator/denominator
= [tex]\frac{6}{3a}[/tex] ← cancel 6 and 3 by 3

Answer:
1. 3 cookies
2. 2 cups
3. 300 calories
4. $35 per month
5. k = y/x
6. If there is no constant (k)
Step-by-step explanation:
1. The number of cookies the factory makes in one minute = (The number of cookies the factory makes in 12 minutes)/(12 minutes)
∴ The number of cookies the factory makes in one minute = 36 cookies/(12 minutes) = 3 cookies/minute
The correct answer is 3 cookies
2. The number of cups of water that leak every minute = (The number of cups of water that leak in 1/4 minute) × (The number of 1/4 minute per minute)
The number of cups of water that leak every minute = 1/2 cup per 1/4 minute × 4_1/4 minute per minute
The number of cups of water that leak every minute = 1/2 × 4 = 2
The number of cups of water that leak every minute = 2 cups
3. 5 glazed donuts contains 750 calories
∴ 1 glazed donuts contains 750/5 = 150 calories
2 = 2 × 1 glazed donuts will contain 2 × 150 = 300 calories
4. The charge of the cell phone company for 2 months = $70
The charge of the cell phone company for 6 months = $210
The constant rate per month = The rate of change of the cell phones companys charges
∴ The constant rate per month = (210 - 70)/(6 - 2) = 140/4 = 35
The constant rate (per month) for the service = $35 per month
5. The formula to find the constant of a chart, k = y/x

1. Stacey earns $15 each week plus 5.50 for each customer on her paper route. She wants to earn at least $25 each week. What equation can
she use to find the number of customers she needs to make exactly $25?
Step-by-step explanation:
Let the no. Of customers be N.
25 = 15 + 5.5N
This is the required eqn.
Stacey can use the formula, 25 = 15 + 5.50x to find out the number of customers she needs to make $25 weekly.
Stacey makes $15 in a week without having any customers. She will however, make $5.50 for every customer on her paper route.
The expression for the amount she makes per customer and assuming the number of customers is represented by x is therefore:
= Amount per customer × Number of customers
= 5.50 × x
= 5.50x
When this is added to the amount she makes without customers it is:
= 15 + 5.50x
Stacey wants to make $25 per week using the above expression so the full expression would be:
25 = 15 + 5.50x
In conclusion, Stacey can find the total number of customers she needs to make $25 per week by the expression 25 = 15 + 5.50x.

How do you solve the equation above using substitution? Please show work :)
Answer:
the solution is (21/2, 19/2)
Step-by-step explanation:
The first equation, x = y + 1, has already been solved for x. We can eliminate x in the second equatin by substituting y + 1 for x:
y = -(1/3)(y + 1) + 6
Let's eliminate fractions by multiplying all three terms by 3:
3y = y + 1 + 18
Combining like terms results in:
2y = 19, so that y = 19/2.
Substituting this 19/2 for y in the first equation, we get:
19/2 + 2/2 = x, or
x = 21/2
Thus the solution is (21/2, 19/2)
