Which are true and which are false? 2+5=8-1. 4+2=9-1. 13-0=12+1
stiks02 [169]

Hi there,

I believe there are 3 questions.

  1. 2+5=8-1 It is true because 2+5 is 7 and 8-1 is 7. So, both sides have same value which means they are equal.
  2. 4+2=9-1 It is false because 4+2 is 6 and 9-1 is 8. So, the values are different.
  3. 13-0=12+1 It is true because 13-0 is 13 and 12+1 is 13. Both values are same. Therefore, they are equal.

Hope it helps :-)

If you got a 1.25% interest rate how long would you need to invest $6000 if you wanted to earn $105 in interest
gavmur [86]

Answer:

1.4 years

Step-by-step explanation:

Use the formula for simple Interest:

I = P * r * t

Where I is the interest gained (in your case $105),

P is the principal (in your case $6000),

r is the annual interest rate in decimal form (in your case 0.0125)

and t is the time (in years) you need to find.

Therefore, we 105 = 6000 * 0.0125 * t = 75 * t\\t = \frac{105}{75} = 1.4 yearssolve for "t" in the following equation:
