Answers

Answer 1

Answer: 27 - 15 = 12
Adding 15 to both sides, we have,
27 - 15 + 15 = 12 + 15
i.e. 27 = 12 + 15
Answer: C [12 + 15 = 27]

To calculate by estimation, round each number to the nearest ten, hundred, ets as the case may be.
Here, rounding to the nearest ten, we have,
267 - 154 = 270 - 150 = 120.
Answer: C

Quotient of 18 and 2 = 18/2 = 9
Sum of 22 and 9 = 22 + 9 = 31
Subtracting the quotient of 18 and 2 from the sum of 22 and 9, we have:
31 - 9 = 22
Answer: D

Simplify 3j - {2k - [5h - (3j + k)]

Answers

Simplification:

$3j-[2k-[5h-(3j+k)]]$

= $3j-[2k-(5h-3j-k)]$

= $3j-(2k-5h+3j+k)$

= $3j-2k+5h-3j-k$

= $3j-3j-2k-k+5h$

= $0-3k+5h$

= $-3k+5h$

= $5h-3k$

Answer: the correct answer is 5h-3k
