1.5(x+4)-3=4.5(x-2)

First, distribute 1.5 into x and 4, and 4.5 into x and -2, to get rid of the parentheses. Everything that we do to solve this equation is to isolate x to solve for its value.

1.5x+6-3=4.5x-9

Combine like terms on both sides (6-3).

1.5x+3=4.5x-9

Subtract 1.5x from both sides.

3=3x-9

Add 9 to both sides.

12=3x

Divide both sides by 3.

4=x

The answer is 4.

I hope this helps :)

A circle has an area of 497 square inches. What is the circumference of the circle?
Aleksandr-060686 [28]

Answer:

easy peasy

Step-by-step explanation:

we have, area = 497 sq. units

that is, (pi) (radius)^2=497

=> (22/7) x r^2 = 497

=> r^2 = 158.13

=> r = √158.13

=> r = 12.57

now we also have radius, soooo

=> circumference = 2 (pi) (radius)

=> (2) (22/7) (12.57)

=> 79.01 inches

What would be the value of $100 after 10 years if you earn 11 percent interest per year
uysha [10]
10 times 11% is 11 dollars, so 11 times 10 equals 110. Then 110 plus 100 equals 210. So you'd have $210 after ten years with 11 percent interest.

Is there any combination of education and post-graduation? Write the five basic objectives of education
Degger [83]

Answer:

3

Step-by-step explanation:

Actually 'post-graduation' is a type of education. Education only means learning, so post graduation is a type of education.

<u>OBJECTIVES OF EDUCATION:</u>

Usually an educational objective relates to gaining an ability, a skill, some knowledge, a new attitude etc. rather than having merely completed a given task.
