Answer:
3.370459909
Step-by-step explanation:
Figure out the arithmetic mean of the numbers (22.8)
Subtract the mean from each number and square the difference
Add up the squared differences and divide the number by 5
Square root answer
The answer is B. 6.5f+2.5 because 13/2 is 6.5 and 5/2 is 2.5
As you can see, this is a multiplication root.
y = 4 · x
x = 7 · 3
So solve for x first to solve for y.
x = 7 × 3
x = 21
y = 4 · x
y = 4 × (21)
y = 84
Answer: The answer is d=2x+3(x+1.5)=12
Step-by-step explanation:
Answer:
They are equivalent
Step-by-step explanation:
We can do cross products for this one
17/3 = 68/12
17 times 12 = 68 times 3
204 = 204
