Emily attends a Film Festival. The admission fee is $10. Each movie ticket cost $5 each. Emily wants to determine how many movie tickets she can buy if she has a total of $40 before she pays the admission fee.
Answer:
Emily can buy 6 movie tickets after paying the admission fee
Step-by-step explanation:
Let x be the number of movie tickets
If each movie ticket costs 5 dollars then the cost of x movies will be 5x
And the admission fee will be a constant.
She has $40 in total
So the equation can be written as
[tex]10+5x = 40\\5x = 40-10\\5x = 30\\\frac{5x}{5} = \frac{30}{5}\\x = 6[/tex]
Hence,
Emily can buy 6 movie tickets after paying the admission fee

Mia has $50 on a gift card to her favorite coffee shop. Each time she visits the coffee shop she spends $3.75 on her favorite drink. Write an equation to represent the relationship between x, the number of times she visits the coffee shop, and y, the total amount on her gift card.
Answer:
y=$3.75x
Step-by-step explanation:
$50 is equal to 'y'. 'x' is the number of days Mia goes to the coffee shop. For every day Mia goes to the coffee shop, she spends $3.75 on her favorite drink
The required expression for the balance gift card is y = 50 - 3.75x.
Given that,
Mia has $50 on a gift card to her favorite coffee shop. Each time she visits the coffee shop she spends $3.75 on her favorite drink. To determine an equation to represent the relationship between x, the number of times she visits the coffee shop, and y, the total amount on her gift card.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
Here,
Total money spent on the drink = 3.75x
Money left in the gift card after paying 3.75x from the $50 gift card is = 50 - 3.75x.
So,
y = 50 - 3.75x
Thus, the required expression for the balance gift card is y = 50 - 3.75x.

Donna is on the swim team. Each week she swims a total of 8000 meters. How many kilometers does she swim each week? Be sure to include the correct unit in your answer.
Answer:
Donna swims 8 km each week.
Step-by-step explanation:
To be able to find the answer, you have to consider that 1 km is equal to 1000 meters and with this, you can use rule of three to find the kilometers in 8000 meters:
1 km → 1000 meters
x ← 8000 meters
x=(1*8000)/1000=8 km
According to this, the answer is that Donna swims 8 km each week.

PLEASE HELP I DON'T UNDERSTAND! A florist is making regular bouquets and mini bouquets. The florist has 118 roses and 226 peonies to use in the bouquets. Each regular bouquet has 5 roses and 11 peonies. Each mini bouquet has 3 roses and 5 peonies. Reply to this post by doing the following: 1. Write an equation that shows the total number of roses to be used in both kinds of bouquets. 2. Write an equation that shows the total number of peonies to be used in both kinds of bouquets. 3. Find how many of each bouquet can the florist make.
Answer:
The florist can make 11 regular bouquets and 21 mini bouquets
Step-by-step explanation:
The number of roses the florist has = 118 roses
The number of peonies the florist has = 226 peonies
The number of roses in each regular bouquet = 5 roses
The number of peonies in each regular bouquet = 11 peonies
The number of roses in each mini bouquet = 3 roses
The number of peonies in each mini bouquet = 5 peonies
1. The equation that gives the total number of roses to be used in both kinds of bouquet is given as follows;
Let r represent the number of regular bouquet the florist can make and let m represent the number of mini bouquet the florist can make, we have;
5·r + 3·m = 118...(1)
2. Similarly, we have;
11·r + 5·m = 226...(2)
Making m the subject of the formula of both equations, and equating both values of m to find a common solution, we have;
m = (118 - 5·r)/3
m = (226 - 11·r)/5
(118 - 5·r)/3 = (226 - 11·r)/5
5 × (118 - 5·r) = 3 × (226 - 11·r)
590 - 25·r = 678 - 33·r
33·r - 25·r = 678 - 590 = 88
8·r = 88
r = 88/8 = 11
r = 11
The number of regular bouquet the florist can make = r = 11
m = (118 - 5·r)/3 = (118 - 5×11)/3 = 21
m = 21
The number of mini bouquet the florist can make = m = 21
The number of regular bouquet the florist can make = 11 bouquets
The number of mini bouquet the florist can make = 21 bouquets.

Answer:
Check whether the two ratios form a proportion or not: (i) 6 : 8 and 12 : 16; (ii) 24 : 28 ... 3. The first, third and fourth terms of a proportion are 12, 8 and 14 respectively. ... 5. If a : b = 4 : 5 and b : c = 6 : 7; find a : c. Solution: a : b = 4 : 5. ⇒ a/b = 4/5.
Answer:
Let the fourth term be x
7/14=25/x
7x=14*25
x=350/7
x=50

Mr.Martin states that in order for the solution to the equation 3x + q = 6 to be positive, the value of q must be less than 6. Select a value of q that is less than 6 and show that the solution to the equation 3x + q = 6 is positive. Select a value of q that is not less than 6 and show that the solution to the equation 3x + q = 6 is not positive
Answer:
Mr. Martin's statement is correct.
Step-by-step explanation:
First we select a value of q that is less than 6:
q = 3
Then we write the equation:
3x + 3 = 6And solve for x:
3x = 6 - 43x = 3x = 3/3x = 1The solution is positive because x > 0.
--
Then we select a value of q that is not less than 6:
q = 9
Then we write the equation:
3x + 9 = 6And solve for x:
3x = 6 - 93x = -3x = -3/3x = -1The solution is negative because x > 0.
