Answer:

There are 9 boys in the choir

Step-by-step explanation:

To solve this, create two equivalent fractions with the information given

boys      3         x

------- = ------ = ------

girls       4         12

Then, cross-multiply

4x = 3(12)

4x = 36

x = 9

Use the slope formula to find the missing coordinate: R(0,_), S(-4,2) m=5
Delicious77 [7]

Answer

The missing value is 22

step-by-step explanation

The slope formula is

m =  \frac{y_2 - y_1}{x_2 - x_1}

From the question,

m=5

x_2=-4

y_2=2

and

x_1=0

We substitute these values to get,

5=  \frac{2 - y_1}{ - 4- 0}

Simplify

5=  \frac{2 - y_1}{ - 4}

5 \times  - 4=2 - y_1

- 20=2 - y_1

- 20 - 2=- y_1

22= y_1

y_1 = 22

The missing value is 22

Can you describe multiplying and dividing signed numbers in the real world? plz Explain
elena-14-01-66 [18.8K]

The example I would be using is the level of a see-saw and take a point 1 /x of the way amid the middle and the left end. If you change the point vertically by f feet, the far right finish transfers vertically by f×−x feet. If you push down, f would be negative then you are multiplying two negative numbers for a positive result, this means that the other end moves up.

Craig likes to collect video records last year he had 10 records his collection now has 12 records what is the percent increase
algol [13]
I believe the answer is a 20% increase because 12-10 equals 2. there is a 2 record difference so 2 out of 10 is 1/5 of the whole, but you have to convert the numbers and 1/5 of the whole of 100 is 20. sorry if that didn’t make much sense
