Step-by-step explanation:
When a number is multiplied by 5, the last digit of the product must be 0 (mod 5).
=> Last digit = 0 or 5.
Since 0 is not an option here, the answer must be 5. (C)
The LCD of 1/2 and 1/3 is 6
Rewriting input as fractions if necessary:
1/2, 1/3
For the denominators (2, 3) the least common multiple (LCM) is 6.
Therefore, the least common denominator (LCD) is 6.
Rewriting the original inputs as equivalent fractions with the LCD:
3/6, 2/6
Answer: X = 2
Step-by-step explanation:
Answer:
(- 1, - 1 )
Step-by-step explanation:
Given the 2 equations
y = 4x + 3 → (1)
x + y = - 2 → (2)
Substitute y = 4x + 3 into (2)
x + 4x + 3 = - 2, that is
5x + 3 = - 2 ( subtract 3 from both sides )
5x = - 5 ( divide both sides by 5 )
x = - 1
Substitute x = - 1 into (1)
y = 4(- 1) + 3 = - 4 + 3 = - 1
Thus x- value is - 1 and y- value is - 1
Answer:
£4113.70
Step-by-step explanation:
Given that:
143 people pay ; out of which 38 are under 16 ;
Hence ; 143 - 38 = 105 are over 16
Under 16 = £17.90
£17.90 * 38 = £680.20
16 and Over : = £32.70
£32.70 * 105 = £3433.50
£(680.20 + 3433.50) = £4113.70
