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

If the production increased the current amount, then is double what the current amount is, and therefore it increased by 100%. If twice as much, then by 200% and so on.
The answer is 0.77777777777778. Also here is my work, so you divide 7 by 9, and 9 can go into 7 0 times so now add a decimal to 7 and you get 7.0, so 9 can go into 70, 7 times so 9 times 7 equals 63 and keep doing it for infinity.
