Solve 4x + 2 = 20 klkllk

Mathematics
1 answer:
Archy [21]3 years ago
6 0

Answer:

x = 4.5

Step-by-step explanation:

First, we can subtract 2 from 20 (20 - 2) to get 18.

Now we know that x has to be multiplied by 4 and have a product of 18.

We can divide 18 by 4 to figure out what x is.

18 ÷ 4 = 4.5

We can check our answer by solving the equation:

4(4.5) + 2 = 20

18 + 2 = 20

20 = 20

(sorry if this is confusing but I hope it helped)

Joseph has a job walking dogs and gets paid per dog. He needs to walk 45 dogs to earn enough money to pay for his soccer team fe
rusak2 [61]

Using proportions, it is found that it will take him 22.5 hours to walk the 45 dogs.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

He walks 3 dogs in 1 hour and 30 minutes, we means that the time in hours it takes for him to walk a dog is:

t = 1.5/3 = 0.5 hours.

Hence the time it will take him to walk 45 dogs is given by:

45 x 0.5 = 22.5 hours.

PLZ HELP FAST the bank at which shareko deposits his money pays 5 1/4 % simple interest annually . How much interest will he ear
NemiM [27]

Answer:

Step-by-step explanation:

Simple interest rate applies only to the principal amount deposited and not the compounded amount. The formula for simple interest is expressed as

I = PRT/100

Where

I is the interest.

P is the principal or initial amount deposited.

R is the interest rate.

T is the duration in years.

From the information given,

P = $300.00

R = 5 1/4% = 5.25%

T = 6 months = 0.5 years

Therefore,

I = (300×5.25× 0.5)/100 =787.5/100

I = 7.875

The balance in the account at the end of this time will be

300 + 7.875 = $307.875
