Answer:
Subtracted 3 from (24+3)
Step-by-step explanation:
3m - 3 + 3
24 - 3 + 3
Since the adding and subtracting go left to right, you can do them in that order.
21+3 = 24.
Now which one gives us 24?
(24+3) - 3
Answer:
D
Step-by-step explanation:
If you look at the right side of each piecewise function, you will see the x-values. That is what we will be focusing on in this explanation. All four equations have x <u>></u> 4, and we know that to be true. If you look at the equation on the graph going South West, you will see that the endpoint is at x=1. Only 1 equation, D, has this in the piecewise function. To confirm it is D, you can see that 1<x<4 is also in the piecewise function, and all the values line up with their corresponding y-values.
Hope this helps! :)
Answer:
0.4kg, 1.4kg and 1.8kg
Step-by-step explanation:
Given parameters:
Mass of alloy = 3.6kg
Ratio of elements in the alloy = 2:7:9
Unknown:
Mass of each element in the alloy = ?
Solution:
To find the mass of each element in the alloy, first find the sum of the ratio;
2+7+9 = 18
Mass of nickel = 
x 3.6 = 0.4kg
Mass of zinc = 
x 3.6 = 1.4kg
Mass of copper = 
x 3.6 = 1.8kg
The mass of each metal is 0.4kg, 1.4kg and 1.8kg
0.75 miles in 12 minutes
0.75 * 5 miles in one hour
15 / 4 miles in an hour
