We have been given that Lydia uses 15 grams of protein powder to make a 22-ounce shake. She decides to make shakes for the week and plans to make 198 ounces. We are asked to find the grams of protein powder Lydia will use.
We will use proportions to solve our given problem.
Therefore, Lydia will use 135 grams of protein powder for the entire week.
Remove parentheses; it's the same thing with addition and subtraction.
2+11+y
13+y
2+(11+y) is equivalent to 13 + y.
The answer for the equation: 1x1 is 1
The mean is calculated by adding up all of the given numbers and dividing by the number of numbers.
Lets, for ease of understanding, say that the first three number were 64...
Mean=(64+64+64)/3=192/3=64
Now, lets solve for the mean where 'x' is the unknown fourth number and 128 is the mean. (since, the answer said that when the fourth number was added the mean, 64, was doubled '64*2=128')
128=(64+64+64+x)/4
128=(192+x)/4
Multiply both sides by 4
512=192+x
subtract 192 from both sides
320=x
The missing number is 320..
Now lets double check our work.
Mean=(64+64+64+320)/4=512/4=128
Answer=320
Answer:
because she "made up time"
Step-by-step explanation:
When she increased her pace, she basically made up for lost time standing at the location. assuming that she made it in the same amount of time if she didn't stop, you can assume that she did not waste anymore time because she picked up the pace.
