250

Step-by-step explanation:

The cost is 7 times y, the number of yearbooks, plus 150, the upfront cost.

7 times 100 is 700, plus 150 is 850.

1900-150 is 1750 divided by 7 is 250

Step-by-step explanation:

There are 12 children tickets did the group buy.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The group bought 20 admission tickets for $340.

And, Adult tickets cost $20, and children’s tickets cost $15.

Let number of children = x

And, Number of adult = y

Hence, We get;

The system of equations are,

x + y = 20  

y = 20 - x .. (i)

And, 15x + 20y = 340

3x + 4y = 68 .. (ii)

Substitute the value of y from (i) in (ii);

3x + 4(20 - x) = 68

3x + 80 - 4x = 68

80 - 68 = x

x = 12

Thus, There are 12 children tickets did the group buy.

Answer: a

Step-by-step explanation:

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:

$26320

Step-by-step explanation:

Percentage solution with steps:

Step 1: We make the assumption that 172000 is 100% since it is our output value.

Step 2: We next represent the value we seek with x.

Step 3: From step 1, it follows that 100% = 172000.

Step 4: In the same vein, x% = 13760

Step 5: This gives us a pair of simple equations:

100% = 172000(1).

x% = 13760(2).

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left-hand side) of both equations have the same unit (%); we have

100% / x% = 172000 / 13760

Step 7: Taking the inverse (or reciprocal) of both sides sides

x% / 100% = 13760 / 172000

=> x = 8%

Therefore, 13760 is 8% of 172000.

Now, I would multiply 329,000 by 8%(or 0.08) to get the answer 26320

Hope this helps!

He pays in property taxes $26320 if they live in a $329,000 home in the same area.

We have the following information available from the question is:

The property taxes on a home varies directly with the value of the home. Jack currently lives in a home worth $172,000 and pays $13,760 in taxes.

We have to find the how much would someone pay in property taxes?

Lets assume that:

The home worth cost is $172,000 is 100%

Let the property taxes be x

So, We equal to the value are:

$172,000 = 100%

Similarly, x% = $13,760

This gives us a pair of simple equations:

100% = $172000___(1).

x% = $13760___(2).

By simply dividing equation 1 by equation 2, we get:

100% / x% = 172000 / 13760

Taking the inverse (or reciprocal) of both sides sides

x% / 100% = 13760 / 172000

=> x = 8%

Therefore, 13760 is 8% of 172000.

They live in a $329,000 home in the same area, So

Multiply 329,000 by 8%(or 0.08)

=> 26320
