Answer:
B
Step-by-step explanation:
To make this equation easier, we can just divide the data by 2, so that the exact number of eggs that survived, is the percentage that survived.
Explanation:
200 = 200 Total Eggs
136 = 136 Eggs That Broke
So, the ratio of eggs that broke to total eggs is:
136 / 200
So, subtract the number of eggs that broke to the total eggs, to find the amount that survived.
200 - 136 = 64
So now we know that, 64 eggs of 200 survived.
Which means, that 32% off the eggs had survived.
Answer:
Step-by-step explanation:
x - 30 = 14 - 3x
4x = 44
x = 11
Let's call the unknown number x
Now let's decrease it by 30, that is x-30
Now let's write out "14 decreased by three times the number", that is 14 - 3x
The problem says these are the same, that is x - 30 = 14 - 3x
We now want to isolate, or solve for, x
Move the x to one side of the equation by adding 3x to both sides
3x + x -30 = 14 - 3x + 3x
4x -30 = 14
Now move the 30 to the right hand side by adding 30 to both sides
4x - 30 + 30 = 14 + 30
4x = 44
Now all we have to do to get x is divide both sides by 4
4x/4 = 44/4
x = 11
It is 35 degrees a piece. Check the previous answer between both of us for clarification.
