Hi there!
We need to add the total together, including the socks and the total needs to be less than or equal to 100. The inequality we would use is 3(29.57) + 8.95s <= 100 | 88.71 + 8.95s <= 100.
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
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
Answer:
1. -2+2x=y
Step-by-step explanation:
You only need to try the first two lines of the table to determine which equation works.
Only equations 1 and 4 work for the first line of the table (x=0).
- 1. -2 +2·0 = -2 . . . . . . . this works
- 2. 2 -2·0 = 2 ≠ -2
- 3. 2 +2·0 = 2 ≠ -2
- 4. -2 +0 = -2 . . . . . . . this works
Of those, only equation 1 works for the second line of the table (x=1).
- 1. -2 +2·1 = 0 . . . . . . . this works
- 4. -2 +1 = -1 ≠ 0
The equation that is true for the table values is ...
-2 +2x = y
After 3 hours, you will be on 450 mile marker.
Step-by-step explanation:
<u>step 1:</u> At start, the number in the mile marker is 100
<u>step 2:</u> After 4 hours, the number in the mile marker is 300
<u>step 3:</u> The difference of 300-100= 200. In 4 hours you crossed 200 mile markers.
<u>step 4:</u> Therefore, for 1 hour you can cross= 200/4= 50 mile markers.
For 3 hours, the number of mile markers crossed= 3*50= 150 mile markers.
<u>step 5:</u> After 3 hours, the number in the mile marker will be= 300+150= 450
Answer:
Step-by-step explanation:
the formula is C=2√πA
so simplifying that would give us c=2(4π)
simplify again and we get c=8π
