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: $358.8 to the nearest tenth
Step-by-step explanation:
Compound interest is calculated by Where: A = P(1 + r)t
Where P= 300, r= 12% = 0.12, t= 1.5 years
Slot in the figures
300 (1 + 0.12) 1.5
300 (1.12) 1.5
300x 1.12
336e1.12
A = $ 358.84
Recall that the sum of all 3 angles of a triangle is 180. So,
82 + 45 + x = 180>> 127 + x = 180
>> x = 180 - 127
>> x = 53 (final answer)
Answer:
Movie cost $3.5 and the video game cost $5.5
Step-by-step explanation:
Given data
Let the cost of movies be x
and the cost of video game be y
12x+2y= 53----------1
and
3x+5y= 38-----------2
solve 1 and 2
12x+2y= 53X 5
3x+5y= 38 X2
60x+10y= 265
- 6x+10y= 76
54x= 189
x= 189/54
x= $3.5
put x= 3.5 in 1
12(3.5)+2y= 53
42+2y= 53
2y= 53-42
2y= 11
y= 11/2
y= $5.5
Hence the movie cost $3.5 and the video game cost $5.5
