Determine the number of solutions for the equation 1 - 3(x - 2) = 7 - 3x

2 answers:

8 0

I would say you have an infinite number of solutions for this equation. This is because when you expand the bracket on the left, you get 1 - 3x + 6 which is 7 - 3x, which is the same as on the right. The reason the solutions would be infinite is because they're multiplied by the same thing and added to the same thing, so they're always gonna be the same.

I hope this helps!

1/2x=5/4 solve the equation and inequalities

aivan3 [116]

The equation is simplified to x = 3/2

<h3>What are linear equations?</h3>

Linear equations are equations with the highest power of a variable as 1

Given the equation;

1/ 2x = 5/ 4

cross multiply

4 × x = 2 × 5

4x = 10

Make 'x' the subject

x = 10/ 4

Reduce to simplest term

x = 3/ 2

Thus, the equation is simplified to x = 3/2

1. What is the area of a circle with a diameter of 12.6 in.?

Rudik [331]

Answer:

Part 1) $A=124.63\ in^{2}$

Part 2) Option b

Part 3) As n increases, ns get closer to $2\pi r$

Part 4) Option c $16\pi\ ft^{2}$

Part 5) Option b. $12.25\pi\ m^{2}$

Step-by-step explanation:

Part 1) What is the area of a circle with a diameter of 12.6 in.?

we know that

the area of a circle is equal to

$A=\pi r^{2}$

we have

$r=12.6/2=6.3\ in$ -----> the radius is half the diameter

substitute the values

$A=(3.14)(6.3^{2})=124.63\ in^{2}$

Part 2) Which explanation can be used to derive the formula for the circumference of a circle?

First find the relationship of the circumference to its diameter by finding that the length of the diameter wraps around the length of the circumference approximately π times.

Use this relationship to write an equation showing the ratio of circumference to diameter equaling π

$\frac{C}{D}=\pi$
