Question

Q. Evaluate each algebraic express
On.
i. (-10m - 7) +(-20 - 14)
ii. (150m + 100) + (90m + 6)
iii. (- 3n + 4) + (6 + 7)
iv. (4m + 3) + (-2m-3)
v. (3k + 2) + (-3k +5)​

Answer 1

Step-by-step explanation:

i. (-10m - 7) +(-20 - 14)  = -10m - 7 - 20 - 14 = -10m - 41

ii. (150m + 100) + (90m + 6)  = 150m + 90m + 100 + 6 = 240m + 106

iii. (- 3n + 4) + (6 + 7)  = -3n + 4 + 6 + 7 = -3n + 17

iv. (4m + 3) + (-2m-3)  = 4m - 2m + 3 - 3  = 2m + 0 = 2m

v. (3k + 2) + (-3k +5)​ = 3k - 3k + 2 + 5 = 0 + 7 = 7
