Answer:

x=10

Step-by-step explanation:

Let's solve your equation step-by-step.

40−x=3x

Step 1: Simplify both sides of the equation.

40−x=3x

40+−x=3x

−x+40=3x

Step 2: Subtract 3x from both sides.

−x+40−3x=3x−3x

−4x+40=0

Step 3: Subtract 40 from both sides.

−4x+40−40=0−40

−4x=−40

Step 4: Divide both sides by -4.

−4x

−4

−40

−4

x=10

Answer:

w ≥ 1

Step-by-step explanation:

Given

5w ≥ - 6w + 11 ( add 6w to both sides )

11w ≥ 11 ( divide both sides by 11 )

Is 3 /47 a terminating or a repeating number

katrin2010 [14]

I believe you’re asking 3 divided by 47, but no it does not terminate, it’s a never ending decimal (irrational)

Answer:

Step-by-step explanation:

Using the similarity theorem;

AB/BC = AD/AB

x/7+3 = 7/x

x/10 = 7/x

x^2 = 70

x = √70

Hence the required value inside square root is 70

What is the distance between the longest dog in the shortest dog Short 7 over 8 longest 3 over 8 what is the difference

Step2247 [10]

Answer:

The distance between the longest dog and the shortest dog is 4 over 8 ( $\frac{4}{8}$ ) OR 1 over 2 ( $\frac{1}{2}$ )

Step-by-step explanation:

From the question,

Short is 7 over 8, that is,

Short = $\frac{7}{8}$

and longest is 3 over 8, that is

Longest = $\frac{3}{8}$

The distance between the longest dog and the shortest dog can be determined by finding the difference between the fractions. That is,

$\frac{7}{8} - \frac{3}{8} = \frac{7 - 3}{8}$

$= \frac{4}{8}$

$= \frac{1}{2}$

Hence, the distance between the longest dog and the shortest dog is 4 over 8 ( $\frac{4}{8}$ ) OR 1 over 2 ( $\frac{1}{2}$ ).
