Serhud [2]
Of 5 out of 12 (5/12) are sports games and 3 out of 12 (3/12) are educational, then you would add these together because you need a total for both because it would include one or the other, so both.

5/12 + 3/12= 8/12 or 2/3 are one or the other.

(Number 5)help plzzz
EleoNora [17]

Answer:

See below.

Step-by-step explanation:

So we want to prove that:

\sqrt8+\sqrt2=3\cdot 2^{\frac{1}{2}}

First, simplify √8. This is the same as:

\sqrt8=\sqrt{4\cdot 2}=\sqrt4\cdot\sqrt2=2\sqrt2

Therefore, our equation is now:

2\sqrt2+\sqrt2=3\cdot2^{\frac{1}{2}}

Combine like terms on the left:

3\sqrt2=3\cdot 2^\frac{1}{2}}

The square root of something is the same as taking that number to the one-half power. Thus:

3(2)^\frac{1}{2}}=3\cdot 2^\frac{1}{2}}

Rewrite:

3\cdot2^\frac{1}{2}}\stackrel{\checkmark}{=}3\cdot2^\frac{1}{2}}

And we're done!

State true or false. If 9 is the solution of variable x in the equation fraction numerator 5 straight x space minus space 7 spac
Gekata [30.6K]

Answer:

False

Step-by-step explanation:

Based on what is stated in the question :

Expressing the worded equation Mathematically,

(5x - 7) / 2 = y

If y = 28

(5x - 7) / 2 = 28

Cross multiply

5x - 7 = 28 * 2

5x - 7 = 56

5x = 56 + 7

5x = 63

x = 63 / 5

x = 12.6

Hence, x ≠ 9
