Answers:

21.75

1.37

10

15

Step-by-step:

Dozen flyers:price

4:7.25

12:x

To solve this mulitply 7.25 by 3 (because this is what we multiplied 4 by to get 12) 7.25*3=21.75

Question 2:

We can write teh following equation

.49+.22(x-1)=price

This is essentially saying that we pay .49 for the first ounce and .22 for every ounce after that

We can plug in an x value to get

.49+.22(5-1)

.49+.22(4)

.49+.88

1.37

Question 3:

We can write the following equation

x+2=y

We need to find out what happens when x=8

8+2=10

Question 4:

We can solve this with ratios

x:y

1.5:4.5

5:x

To solve just multiply 4.5 by 10/3 and get 15

We can just multiply

Answer:

1. 7.25/4=1.8125 so 1.8125x12=21.75

2. 0.49+(0.22x4)=1.37

3. rule is x+2=y so x=8 then y=10

4.rule is 3(x)=y so x=5 then y=15

Answer:

question a: yes, at a rate of .01923 (52 if you divide the other way)

question b: C. 6.25/377 = y/72

Step-by-step explanation:

a) 5.25/273 = .01923

   6.25/325 = .01923

   7.25/377 = .01923

   9.25/481 = .01923

b) C. 6.25/377 = y/72

Answer:

Ariana is correct. The difference in the price is $3. So the percentage that you saved has to equal $3.

Step-by-step explanation:

$15.00 x .10 or 10% = $1.50

$1.50 x 2 will give you 20%

$1.50 x 2 = $3.00

$15.00-$3.00 = $12.00

Answer:

$38.50

Step-by-step explanation:

so there are a hundred centimetres in a meter so u have to divide the 250 by 100

250 / 100 = 2.5 meters

and its 15.40 for 1 meter and she bought 2.5 so multiply those

15.40 * 2.5 = 38.50

she paid $38.50 for 2.5 meters of fabric

Answer:

$38.50

Step-by-step explanation:

There are 100 centimetres in a meter. If Mimi bought 250 centimetres of fabric, that is 2.5 meter. So then we do 2.5 x 15.40 = 38.50. Make sure you add the $ sign!

Step-by-step explanation:

Answer: Harvey has $174 per week to spend on entertainment.

Step-by-step explanation: first Add the money he has throughout the week which is $200 + 85 =285 and just subtract $459 and 285.

A fraction is a way to describe a part of a whole. The money that Harvey has to spend on entertainment per week is $58.

A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.

Harvey earns $459 per week and spends $200 per week on rent and utilities, also $85 per week on food. Therefore, the amount of money left with Harvey,

Amount left with Harvey

= Earning - spending on rent and utilities - spending on food

[tex]\text{Amount left with Harvey} = \$459 - \$200 -\$85 =\$174[/tex]

From the leftover money, Harvey deposits 2/3 of the amount leftover into a savings account. therefore, the amount in the saving account is,

[tex]\text{Amount in the saving account} = \dfrac23 \times (\text{Amount of money left})[/tex]

                                                [tex]= \dfrac23 \times ($174)\\\\=\$116[/tex]

Now, the amount left for spending on entertainment is,

[tex]\text{Amount left for spending on entertainment} = \$174 - \$116 = \$58[/tex]

Hence, the money that Harvey has to spend on entertainment per week is $58.

Answer:

they each get 8/10 of the pizza, equal to 4/5 simplified

The fraction of pizza each friend gets is A = 4/5 of the pizza

An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.

Given data ,
