Step-by-step explanation:
Given that the mean of the numbers is 12

so here
let's that one as x and another one as 2x since it is given that one is twice the other
Therefore we get

Given mean = 12




Hence it's 11 and 22
For Y=2x+10 X=y/2 -5. Second x/3
Answer:
x=40
Step-by-step explanation:
you have to get a answer of 60
(40)+20=60
and 2(40)-20=60
Answer:
The table should measure diagonally about 41.23 inches.
Step-by-step explanation:
To find the diagonal of a rectangle we use the formula :
+
= 
A and B both represent the side lengths of the rectangle, while C is the diagonal part. Knowing this formula, let's plug in the values for A and B and see what happens.
+
= 
1024 + 676 = 
1700 = 
The square root of 1700 is (rounded to the hundreth's place) = 41.23
Answer: Use the formula (base1+base2)/2 multiplied by height(3 in)
Step-by-step explanation: I can't see what the bottom base is, but lets say it is 12. 5+12=17, and 17/2=8.5. 8.5*3=25.5
Answer:25.5
