Answer:

4x = 48

Step-by-step explanation:

Since x = 8,

4x = 48

4 * 8 = 32

So 32 is the LHS and 48 is the RHS.

Since the LHS is not equal to the RHS, x=8 is not a solution to the equation 4x = 48

Hope this answer is helpful!!

Answer:

b. 4x = 48

Step-by-step explanation:

If you look closely an multiply 4 x 8, it equals 32, not 48

The other equations:

8 x 8 does equal 64

10 x 8 does equal 80

9 x 8 does equal 72

It's pretty simple once you try each problem first

Hope this helps!

the ratio of the sides of a certain triangle is 2:7:8 if the longest side of the triangle is 40cm how long are the other two sid

Zigmanuir [339]

The length of the other two sides is 10 and 35 respectively.

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

A ratio is a quantitative relation showing the comparison between two or more numbers. It can also be written in the fractional form where the first part is the numerator and the second part is called the denominator.

From the given information:

The sides of the triangle = 2:7:8
The total sides of the triangle = 2+7+8 = 17

We are being told that the longest side is the triangle is equal to 40.

i.e.

$\mathbf{\to\dfrac{8}{17}\times x = 40}$

$\mathbf{x = 40 \div \dfrac{8}{17}}$

$\mathbf{x = 40 \times \dfrac{17}{8}}$

x = 85

Now for the other two sides 2 and 7, their length is as follows.

$\mathbf{\dfrac{2}{17}\times 85 = 10}$

$\mathbf{\dfrac{7}{17}\times 85 = 35}$

Therefore, we can conclude that the length of the other two sides is 10 and 35 respectively.

Check my work 3(x+1)-8=14-2(3x-4)

jeyben [28]

The value of x is 3

Step-by-step explanation:

<u>Equation:</u>

3(x+1)-8=14-2(3x-4)

<u>1. Open the brackets</u>

3(x+1)-8=14-2(3x-4)

3x + 3 - 8 = 14 - 6x + 8

<u>2. Bring all x variables on the left side</u>

3x + 6x = 14 + 8 + 8 - 3

<u>3. Solve</u>

9x = 27

x = $\frac{27}{9}$

x = 3

Therefore, the answer of x is 3.

PLZ HELP!!!!! D: D: IM FAILING PLZ HELP ;cccc

Arada [10]

-2 is larger than -5
or
-2 is greater than -5

-----------------------------------------------------------------------------------------------------------

a loss of 5 points is greater in magnitude than a loss of 2 points
meaning that the person who lost 5 points had a bigger loss (even though -5 is smaller than -2)

Another way to think of it: -5 is further away from 0, compared to the distance from -2 to 0. I recommend drawing a number line if you're having trouble visualizing it.

[ Please help ] The graph of a function f(x) is shown below.

Slav-nsk [51]

we know that

Domain:

Domain is all possible values of x for which any function is defined

For finding domain from any graph , firstly we will find smallest x-value and then largest x-value of curve

and that would be domain

Here , we have

smallest x-value is -3

but there is a hole at x=-3

so, function is not defined at x=-3

largest x-value is 1

so, domain would be

$-3$ .................Answer
