Twice a number m minus three equals the sum of m and five

Answers

The value of 'm' for the given equation as per linear equation will be 8.

What is a linear equation?

Linear equation is an equation where the variable has the highest degree of 1.

Given, twice a number m minus three equals the sum of m and five.

Therefore, the linear equation will be:

2m - 3 = m + 5

⇒ 2m - m = 5 + 3

⇒ m = 8.

The value of 'm' is 8.

2m - 3 = m + 5

m = 8

2(8) - 3 = 13

(8) + 5 = 13

m = 8

A doghouse is to be built in the shape of a right trapezoid, as shown below. What is the area of the doghouse? A right trapezoid with top side 7 feet and height 7 feet. The bottom side is extended to the right with 5 more feet.
45.5 square feet 63 square feet 66.5 square feet 84 square feet

Answers

Answer:

Area of of the doghouse which is in the shape of right trapezoid is 66.5 square feet.

Step-by-step explanation:

Consider a right trapezoid with top side AB is 7 feet and height AD is 7 feet. The bottom side DC is extended to the right with 5 more feet.that is (7+5) 12 feet.

We have to find the area of the doghouse which is in the shape of right trapezoid .

$\text{Area of trapezoid}=(1)/(2)* (\text{sum of parallel sides})* {\text{(Height)}}$

that is,

$\text{Area of trapezoid}=(1)/(2)* (AB+DC)* (AD)$

Substitute the values, we get,

$\text{Area of trapezoid}=(1)/(2)* (7+12)* 7$

$\Rightarrow \text{Area of trapezoid}=(1)/(2)* 19* 7$

$\Rightarrow \text{Area of trapezoid}=(1)/(2)* 133$

$\Rightarrow \text{Area of trapezoid}=66.5$

Hence, Area of of the doghouse which is in the shape of right trapezoid is 66.5 square feet.

How many solutions does the equation 9x+27=27 have ?

Answers

First we rearrange to make x = a number

9x + 27 = 27 <- subtract 27 from both sides
9x = 0

When x ='s a number there is 1 solution.
The answer is 1 solution.

Here are some examples to distinguish how many solutions something has:
> No solution, 0 = 12
> One solution, Y = 6
> Infinite solutions, 0 = 0
