- 1) 4 = 16 divided by n
- k + 5 = 11
- x - 2 = 7
- 7 times a = 42
- 6 = 1/3 times s
- r times 13 = 17
- b - 5 = 16
- No. It should be 24 = 8 times x
- 217 - x = 36
- p = 8180 - 6780
Step-by-step explanation: Cause it is
Knowing the halfway point (which is 5) helps you so you know wither or not the hundred thousands place goes high or stays the same.
So, for this problem 138,202 would round out to 100,000 because the 3 is below 5 so the hundred thousands place stays the same.
Answer:
A
Step-by-step explanation:
The inverse of the statement "if a, then b" will always be "if b, then a". In this case, a = I do my homework and b = it will snow so the inverse is if it snows, then I will do my homework.
Answer:
B. <em>60x⁸</em>
Step-by-step explanation:
(trust me, I got it right on edmentum)
----------------------------------------------
Define x:
----------------------------------------------
Let x be the number of students in the second class:
⇒second class = x
There are 3 more students in the first class than in the second class:
⇒first class = x + 3
There are 2 more students in the third class than in the second class:
⇒third class = x + 2
----------------------------------------------
Expression for each class:
----------------------------------------------
First class = x + 3
Second class = x
Third class = x + 2
----------------------------------------------
Expression for total number of students:
----------------------------------------------
Total = x + 3 + x + x + 2
Total = 3x + 5
----------------------------------------------
Find x:
----------------------------------------------
There are 80 students in total, so
3x + 5 = 80
3x = 75
x = 25
----------------------------------------------
Find the number of students in each class:
----------------------------------------------
First class = x + 3 = 25 + 3 = 28
Second class = x = 25
Third class = x + 2 = 25 + 2 = 27
--------------------------------------------------------------------------------------------
Answer: There are 25 students in the second class.
