Answer:
Chucks spent 8 minutes running and 15 minutes swimming
Step-by-step explanation:
Here, we want to know the amount of time Chuck spends on individual activities.
since the total time spent for the burning is 23 minutes;
then ;
r + w = 23 ••••••••(i)
Now, the number of calories burnt to running for r minutes will be r * 35 = 35w calories
The number of calories burnt to swimming for w minutes will be w * 30 = 30w calories
The addition of both gives the total calories burnt;
Hence;
35r + 30w = 730 ••••••••(ii)
So we have two equations to solve simultaneously ;
From i; r = 23-w
Substitute this into ii
35(23-w) + 30w = 730
805 -35w + 30w = 730
35w -30w = 805-730
5w = 75
w = 75/5
w = 15 minutes
but r = 23 - w
r = 23 -15
r = 8 minutes
Answer:
The chance of rain during the day is 1/10
Step-by-step explanation:
Probability is given by number of possible outcomes ÷ number of total outcomes = 3/30 = 1/10

Answer:
2nd answer choice No, 6/2 does not equal 2/24 :)
Step-by-step explanation:
6/2=3 while 24/10=2.4
Another way you could think about it:
6*2=12
2+2=4
6*3=18
4+2=6
6*4=24
6+2=8
So 24 ounces of the shake would only be 8 grams of protein.
It is wrong because the equation is missing parentheses around the sum
When it says "the quantity of..." it always means parentheses. The correct equation is 2(3x+4)
