2. james is 14
3. 30-14=16
OR
4. 14+16=30
5. kevin is 16 years old
Let speed of water leaking out = x/h
water left in the tank after 24h=20-(speedxtime)
=20-(24x)
=14
20-24x=14
24x=6
x=1/4
Therefore, answer is (a).
Solution:
<u>Note that:</u>
- Given equation: 4(k + 1) = k + 10
- To find: 3k
<u>Simplifying the LHS:</u>
- 4(k + 1) = k + 10
- => (4 x k) + (4 x 1) = k + 10
- => 4k + 4 = k + 10
<u>Subtracting k and 4 both sides:</u>
- 4k + 4 - k - 4 = k + 10 - k - 4
- => 3k = 6 (No further solution required)
The value of 3k is 6.
<span>A number divided by 5 is 3 more than –6.
Let the number be "x".
x/5 = -6 + 3
First combine like terms.
x/5 = -3
Now multiply both sides by 5 to get x on one side.
x = -15
The answer is
C. -15
