Pine Hill Middle School has 300 students. In
Zoey's class, two out of five students belong to
a club. Use this ratio to predict how many
students in the school belong to a club.

Answers

120



Step by step explanation

There are 120 students in the school Pine Hill Middle School who belong to a club.

What is a ratio?

A ratio describes a comparison between two or more quantities in simplest form.

Given that Pine Hill Middle School has 300 students.

Also given two out of five students belong to a club.

∴ We can conclude that (2/5)th of the total students belong to the club which is numerically,

= (2/5)×300.

= 120 students.

We can also solve this by ratios if in a total of 5 students 2 students belong to a club that means 3 students doesn't belong to the club and their ratio is 2:3.

∴ The no. of students belonging to the club is 2/(2+3)×300.

= (2/5)×300.

= 120 students belong to the club.

Please help- A bakery sells cakes for $18 each and pies for $15 each. Last weekend the bakery sold 118 total items and earned $1,932. How many pies were sold last weekend?

Answers

Answer:

64 pies sold

Step-by-step explanation:

x = number of cakes sold

y = number of pies sold

Last weekend the bakery sold 118 total items

x + y = 118

Last weekend the bakery earned $1,932.

18x + 15y = 1,932.

Get rid of one of the terms, in this case x.

x + y = 118 becomes

18x + 18y = 2124

Subtract the equations from each other

(18x - 18x) + (18y - 15y) = 2124 - 1932

3y = 192

y = 64

Subsititue y into the orginal qeuation to solve for x and check it's right.

x + 64 = 118

x = 118 - 64 = 54

18(54) + 15(64) = 1932

64 pies were sold last weekend

How do you convert 18x − 17y = 18 into slope intercept form?

Answers

Answer:

[tex]y=-\frac{18}{17} + \frac{18}{17} x[/tex]

Step-by-step explanation:

First move x terms and numbers on one side, keep y on the other side.

y = mx+b is the form

18x -17y = 18

subtract 18x from both sides

-17y = 18 - 18x

divide both sides by -17

y = -18/17 + 18/17x
