Answer:

14

Step-by-step explanation:

You solve this problem by subtracting 3 from 10 because you have to solve it inversely. After doing this you get 7. Since that is 1/2 a number the number is 14

Answer:

14

Step-by-step explanation:

Let's call the number x.

\dfrac{x}{2}+3=10

Subtract 3 from both sides:

\dfrac{x}{2}=7

Multiply both sides by 2:

x=14

Hope this helps!

<h3>Answer: Everything but the lower right hand corner</h3>

==============================

Explanation:

Notice for the corners mentioned, we have the figures with corresponding angles that are the same (shown by similar arc markings) and they have congruent corresponding sides as well (aka they are the same length shown by similar tickmarks). Rotating one figure has it transform into the other.

The only time this does not happen is with the pair of figures in the bottom right hand corner. One square has side lengths of 20, the other has side lengths of 25. The two figures are not congruent due to the side mismatch.

riadik2000 [5.3K]

Answer:

3) 0.326

Step-by-step explanation:

Total Number of surveyed households =125

We want to determine the probability that a randomly selected household would have a laptop given that it does not  have a tablet.

Written in Probability notation: P(Laptop|No Tablet)

P(Laptop|No Tablet)=\dfrac{P(L\cap T')}{P(T')} \\=\dfrac{31/125}{95/125}\\=\dfrac{31}{95}\\\\=0.326

The correct option is C,

A student solved 3/x−4=x/7 in six steps, as shown.
Stolb23 [73]

Answer:

Option A.

Step-by-step explanation:

The given equation is

\dfrac{3}{x-4}=\dfrac{x}{7}

Step 1: Multiply both sides by (x-4).

3=\dfrac{x(x-4)}{7}

Step 2: Multiply both sides by 7.

21=x(x-4)

Step 3: Using distributive property.

21=x^2-4x

Step 4: Isolate all terms on one side.

0=x^2-4x-21

Step 5: Find factors by splitting the middle term.

0=x^2-7x+3x-21

0=x(x-7)+3(x-7)

0=(x-7)(x+3)

Step 6: Using zero product property, we get

x=-3, x=7

It means student solved the equation correctly.

Therefore, the correct option is A.
