Answer:

63

Step-by-step explanation:

If the 2 in the ratio translates to 14, 14/2=7. So the scale factor is 7. Now we multiply the 7*(Scale Factor)(7)= 49. In the end we add 14+49 to get 63.

Answer: 63 people in total

Step-by-step explanation:

if the ratio is 2:7, then there are 2 chaperones per every 7 students. If there are 14 chaperones then 2 * 7 = 14, so you'd multiply 7 * 7 and get 49. Then add 49 and 14.

2:7

14:?

2/7 = 14/?

2 * 7 = 14

7 * 7 = 49

2/7 = 14/49

6. 6

Which equals x = greater than or equal to six


It has to be greater than or equal to because it had the line under it which means equal to and has the open mouth of the comparison sign facing the left which is greater than. Combine them together

The sum of two numbers is 40 and their difference is 6.5 what is their product
Klio2033 [76]
Let x = first number, and y = second number. 
x + y = 40 (1)
x - y = 6.5 (2)

Rearrange (2) 
y = x - 6.5 (3)

Sub (3) in (1)
x + (x - 6.5) = 40 
2x - 6.5 = 40
2x = 33.5 
x = 16.75 (4)

Sub (4) in (1) 
16.75 + y =40
y = 23.25 

x * y = 16.75 * 13.25 = 221.9375

The product is 221.9375
