Divide 33 photos into two groups so the ratio is 4 to 7

jeka57 [31]

33 photos in a 4x to 7x ratio

4x + 7x = 33
11x = 33
x = 3

33 photos can be put in a 4(3) to 7(3) ratio

which is a 12 to 21 ratio

so 12 photos on one side, and 21 on the other side to get the ratio of 4 to 7

Emma goes miniature golfing. She pays $7.50 for an admission ticket and $6.25 for each round she golfs. The total amount Emma pa

sergiy2304 [10]

Answer:

The equation that can be used to determine the number of rounds that Emma golfs is:

x=(c-7.50)/6.25

Step-by-step explanation:

From the information given, the total amount Emma pays to go miniature golfing is equal to the price of the admission ticket plus the result of multiplying the price per round of golf for the number of rounds and according to this, the equation would be:

c=7.50+6.25x, where:

c is the total cost for Emma to go miniature golfing

x is the number of rounds

Now, you can solve for x to determine the equation that can be used to find the number of rounds that Emma golfs:

x=(c-7.50)/6.25

You can replace c with 26.25:

x=(26.25-7.50)/6.25

x=18.75/6.25

x=3

Naddik [55]

Answer:

horizontal line with a open circle at (20,10) and an closed circle at (30,10)

$ 207.50

Step-by-step explanation:

20.75 is between 20 and 30

From the given table , we can see that

for more than 20, up to 30 pounds, the cost per pound is $10

This means, the pounds greater than 20 and less than 30 cost per pound is $10

More than 20 means pounds not equal to 20. its close to 20

So there is a open circle at 20

Cost per pound remains the same from 20 to 30

So horizontal line with a open circle at (20,10) and an closed circle at (30,10)

Total cost of 20.75 pounds of almonds = 20.75 * 10 = 207.50
