Answer:

x = -7

Step-by-step explanation:

6/x + 8/x + 5 =3

5x + 14 /x =3

Step 1: Multiply both sides by x.

5x+14=3x

5x+14−3x=3x−3x(Subtract 3x from both sides)

2x+14=0

2x+14−14=0−14(Subtract 14 from both sides)

2x=−14

−14

(Divide both sides by 2)

x=−7

Explain how finding 7x20 is similar to finding 7 x 2,000. Then find each product

Sphinxa [80]

7×20 and 7×2000 are similar. The amount of zeros are the dependent factor.

7×20= 140
7×2000= 14000

The base equation is 7×2=14
Any additions of zeroes in this formula will be added at the end result.

Ex.
7×2=14
7×20=140
7×200=1400
70×200=14000
700×200=140000

John deposited $2860 in a bank that pays 9% interest, compounded monthly. find the amount he will have at the end of 3 years ?

7nadin3 [17]

To find that you first need to find what 9% is. You can multiply the number, 2,860 by .09 to find out your answer. That should be equal to 257.40. Since you now have that number, you can multiply it by 36. 257.40 is your average per month and you want to know by 3 years. So then your next step is 257.4*36 (there is 36 months in 3 years) which should be equal to 9,266.40.
