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
in such cases where 2 line intersect each other, opposite angels are equal
so
2x+2 = 3x - 52
now subtracting 2 from both side
2x +2 -2 = 3x - 52 - 2
2x = 3x - 54
subtracting 3x from both side
2x -3x = 3x -54 - 3x
-x = -54
drividing by -1 both side
-x/-1 = -54/-1
x = 54
