Answer:

x=4

Step-by-step explanation:

I used cross multiplication

7+2x/3=5

7+2x/3=5/1

7+2x(1)=5(3)

7+2x=15

2x=15-7

2x=8

x=4

Answer:

x = 4

Step-by-step explanation:

The goal is to get x by itself.

1. Multiply both sides by 3 and you are left with:

7 + 2x = 15

2. Subtract 7 from both sides and you are left with:

2x = 8

3. Simplify by dividing each side by 2 and you are left with the answer:

x = 4

Someone plz help me with this
Phoenix [80]

Answer:

5y^{6}\sqrt{2}

Step-by-step explanation:

We want to  simplify:

\sqrt{50y^{12}}

We rewrite as:

\sqrt{2\times25 \times (y^{6})^2}

We split the radical sign to obtain:

\sqrt{25} \times \sqrt{(y^{6})^2} \times \sqrt{2}

Simplify the square root for the perfect squares to get:

5y^{6}\sqrt{2}

Therefore the simplified form is: 5y^{6}\sqrt{2}

An unfair die is twice as likely to roll an even number than an odd number. what is the probability of it rolling an odd number?
Anarel [89]
The probability is always expressed as a part of the whole. So, it can be in terms of fraction or percentage. The numerator is the number of possible events while the denominator is the number of total events. Let x be the number of times you roll an odd number. So, the number of times you roll an even number would be 2x. The total rolls would then be x + 2x. Thus, the probability of rolling an odd number is

Probability = x/(2x + x) = x/3x = 1/3

which of the following represents the area of a rectangle whose length is 5x-3 and whose width is x+7​
Neko [114]

Answer:

The answer is 5x^2+32x-21

Step-by-step explanation:

To find the area of a rectangle, you have to multiply the length by the width. Then, you will get the equation of (5x-3)(x+7). Then, multiply these two together, therefore getting 5x^2+32x-21.
