Answer:
10/35 84/35
Step-by-step explanation:
2/7 12/5
7 × 5 = 35
2 × 5 = 10
12 × 7 = 84
10/35 84/35
11 = -3k - 22 - 8k
11 = -11k - 22 <em>added like terms (-3k and -8k)</em>
<u>+22</u> <u> +22 </u>
33 = -11k
-3 = k
Answer: k = -3
Amount in compound interest = p(1 + r/t)^nt where p is the initial
deposit, r = rate, t = number of compunding in a period and n = period.
Here,
Amount after t years = 103(1.02)^t
i.e. 1 + r = 1.02
r = 1.02 - 1 = 0.02
Therefore, annual interest rate = 0.02 x 100 = 2%
Answer:
1: 7/10
2: 3/10
3: 4/8 (2/4 or 1/2 if you need to simplify it)
Step-by-step explanation:
1: Convert 2/5 to tenths by multiplying the denominator and numerator by two. 3/10 plus 4/10 is 7/10
2: Convert 4/5 and 1/2 to tenths.
4/5 is going to be 8/10, 1/2 is going to be 5/10.
Subtract 5/10 from 8/10 to get 3/10
3: Convert 1/4 to eighths to get 2/8. Then add 2/8 and 2/8 to get 4/8.
