Step-by-step explanation:
Which expression represents the number 867?
A. 80 + 60 + 70
B. 800 + 6 + 7
C. 500 + 300 + 50 + 10 + 7
D. 500 + 300 + 60 + 70
Checking the answer choices by adding the expression
A. 80 + 60 + 70
= 210
No correct
B. 800 + 6 + 7
= 813
Not correct
C. 500 + 300 + 50 + 10 + 7
= 867
Correct
D. 500 + 300 + 60 + 70
= 930
Not correct
Therefore option C. 500 + 300 + 50 + 10 + 7 is the correct answer
Answer:
r = 7
Step-by-step explanation:
Given
r + 15 = 4r - 6 ( subtract 4r from both sides )
- 3r + 15 = - 6 ( subtract 15 from both sides )
- 3r = - 21 ( divide both sides by - 3 )
r = 7
Answer:
The answer is B. 70
Step-by-step explanation:
First, since K is the midpoint of line segment JL, JK must equal KL.
So, set 9x-1 = 2x+27 and solve.
7x=28 so x=4
Then, since they are asking for JL, using x=4, add together JK and KL.
So, 9x-1+2x+27 = 11x+26 = 11(4) + 26 = 44+26 = 70
