Beth and Pranav are selling cheesecakes for a school fundraiser. Customers can buy New York
Advocard [28]

Answer:

Cost of one New York style cheesecake  = $5

Cost of one apple cheesecake = $9

Step-by-step explanation:

Let cost of one New York style cheesecake be = x

Let cost of one apple cheesecake be = y

Given:

3 New York stile cheesecake and 7 apple cheese cake were sold for a total of $78.

Cost of 3 New York style cheesecake be = 3x

Cost of 7 apple cheesecake be = 7y

Total = $78

We have:

A) 3x+7y=78

12 New York stile cheesecake and 12 apple cheese cake were sold for a total of $168.

Cost of 12 New York style cheesecake be = 12x

Cost of 12 apple cheesecake be = 12y

Total = $168

We have:

B) 12x+12y=168

Dividing each term in equation B by 12.

\frac{12x}{12}+\frac{12y}{12}=\frac{168}{12}

x+y=14

Solving for x in terms of y

Subtracting y both sides.

x+y-y=14-y

x=14-y

Substituting x=14-y in equation A.

3(14-y)+7y=78

Using distribution:

42-3y+7y=78

42+4y=78

Subtracting both sides by 42.

42+4y-42=78-42

4y=36

Dividing both sides by 4.

\frac{4y}{4}=\frac{36}{4}

∴ y=9

Substituting y=9 in x=14-y

∴ x=14-9=5

∴ Cost of one New York style cheesecake  = $5

∴ Cost of one apple cheesecake = $9

A radius is an angle that connects any point on the circle to the center of that circle.
Flura [38]

The answer is false.

A radius is a segment that connects any point on the circle to the center of said circle. An angle requires two lines, and a radius only consists of one line, which further proves that this statement is false.

The Girl Scouts collected $90 for charity while the Boy Scouts collected $60.
Ostrovityanka [42]

So first you’ll have to find the total or the sum of collected.

$90+$60= $150

Because you’re finding the percent of the total collected by girl scouts, divide the amount collected from the girl scouts by the total.

$90/$150= .6

Multiply that by 100 to get %60.
