Answer:
1/8
Step-by-step explanation:
If you add 1/3 +1/8 to get the housing this year you get 11/24 then add that by 1/3 and 1/4 and you will get 25/24 or 1 1/24 then you add last year 1/3+1/4+1/3 and get 22/24 at last you subtract 25/24 by 22/24 and get 3/24 which equals to 1/8 I hope this helps
56.7 because it is on the hundredths place.
The answer is $10 because 123=$6 and 4 hours is =$4 6+4=10
Answer:
The best estimate for the given calculation is 2.8.
Step-by-step explanation:
To determine the correct option regarding the result of this calculation, the mathematical resolution of the same must be developed:
-14 x 1 /9 x (-2 x 9/10) = X
-14 x 1 / 9 x (-18 / 10) = X
-14 x 1 / 9 x -1.8 = X
-14 / 9 x -1.8 = X
-1.555555 x -1.8 = X
2.8 = X
Therefore, the best estimate result for this mathematical operation is 2.8.
Answer:
Question 1: 71 and 72
Question 2: Child 1: 60 lbs, Child 2: 15 lbs
Step-by-step explanation:
Question 1:
Consecutive numbers are 2 numbers right next to each other.
You know the numbers will have to be double digits number.
71 and 72 are consecutive numbers. The sum of them is 143.
71+72=143
Question 2:
For this problem, we can use system of equations to find the mass of the 2 children. Let's say x is the first child and y is the second child.
Equation 1
x+y=75
This equation comes from the combined mass of the 2 children.
Equation 2
x=4y
This equation comes from the first child being 4 times the mass of the second child.
Since we know the value of x, we can use substitution to find y.
4y+y=75
5y=75
y=15
Now that we know the second child is 15 lbs, we can plug this into any of the 2 equations to find the mass of the first child.
x=4(15)
x=60
