Answer:
25
Step-by-step explanation:
Each of the 16 "ratio units" representing all 80 dancers must stand for ...
(80 dancers)/(16) = 5 dancers
Then 5 "ratio units" representing seventh-grade dancers will stand for ...
5 × 5 dancers = 25 dancers
___
Another way to figure this is to write the proportion ...
(seventh-grade dancers)/(all dancers) = 5/16
seventh-grade dancers = (all dancers)×(5/16) = 80×5/16
seventh-grade dancers = 25
Answer:
28
Step-by-step explanation:
20,24,n,32
We add 4 to get from 20 to 24
Add 4 to get from 24 to n
24+4 = 28
Add 4 to get from 28 to 32
This is correct so n = 28
1 recipe ......2 5/8 = 21/8
1/2.................?
21/8 * 1/2
= 21/16
= 1 5/16
Answer:
R (1 1/3 , 3) or (1.333 , 3)
Step-by-step explanation:
R (x,y)
x = 3 - (3 - (-2))/3 = 3 - (5/3) = 3 - 1 2/3 = 1 1/3
y = 2 + (5-2)/3 = 2 + 1 = 3
R (1 1/3 , 3) or (1.333 , 3)
