Answer:
C. The two quantities are equal
Step-by-step explanation:
Column A
Substitute the numbers with the letters
an = a1 + (n - 1) d should be an = 2 + (8 - 1) 5
Work it out, you should get 37
Column B
Substitute the numbers with the letters again
an = a1 + (n - 1) d should be an = 13 + (9 - 1) 3
Work it out, your answer should be 37 as well
Tada, done. The answer is C.
Answer:
9 blocks
Step-by-step explanation:
The total of what John has already walked and the number more he must walk will be equal to the number he has to walk to get to school.
12 + more = 5 + 9 + 7
more = 9 + 5 + 7 - 12 . . . . . subtract 12 from both sides
more = 9
John must walk 9 blocks more.
_____
We recognize that 5+7 = 12, so that last part of the sum totals zero.
Answer:
m=-7/2
Step-by-step explanation:
(5 • (m + 2) - m) - (2m + 3) = 0
2m + 7 = 0
3.1 Solve : 2m+7 = 0
Subtract 7 from both sides of the equation :
2m = -7
Divide both sides of the equation by 2:
m = -7/2 = -3.500
