Question 4 of 10

Mathematics
1 answer:
VARVARA [1.3K]3 years ago
5 0

Answer:

A. x=3

Step-by-step explanation:

4(5x+3)=14x+30

multiply 4 to 5x and multiply 4 yo 3

20x+12=14x+30

move terms

20x-14x=30-12

subtract 20x to 14x and subtract 30 to 12

6x=18

divide both sides by 8

x=3

I have a maths problem :<br> Simplify x+x+y x y<br> I’m not sure how to work it out! Please help!
maks197457 [2]

Answer:

2x+y^2

Step-by-step explanation:

For this, you check to see if any of these variables are the same. There are two x's, and 2 y's. So, you have to multiply x and x, which gives you 2x, and since you multiply the y's it will give you y^2.

So the answer will be 2x+y^2

0.25÷3=x÷1 1/2 That fraction is one and a half.
Sladkaya [172]

Answer:

<h2>x = 1/8</h2>

Step-by-step explanation:

Given the expression 0.25÷3=x÷1 1/2, we are to look for the value of x from the given equation. Rewriting the equation we will have;

\dfrac{0.25}{3} = \dfrac{x}{1\frac{1}{2} }

On simplification;

0.25 * \frac{1}{3} = x * \frac{2}{3} \\ \\ \frac{25}{100}*\frac{1}{3} =\frac{2x}{3}\\\\ \frac{1}{4} *  \frac{1}{3} = \frac{2x}{3}\\\\ \frac{1}{12} = \frac{2x}{3}\\\\cross \ multiply\\\\2x * 12 = 3\\\\24x = 3\\\\Divide \ both \ sides \ by \ 24\\\\24x/24 = 3/24\\\\x = 1/8

Hence the value of x in the expression is 1/8

Solve for y. 3.2 = 2y. please answer thanks :)
PilotLPTM [1.2K]

Answer:

Simplifying

3.2 = 2y

Solving

3.2 = 2y

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-2y' to each side of the equation.

3.2 + -2y = 2y + -2y

Combine like terms: 2y + -2y = 0

3.2 + -2y = 0

Add '-3.2' to each side of the equation.

3.2 + -3.2 + -2y = 0 + -3.2

Combine like terms: 3.2 + -3.2 = 0.0

0.0 + -2y = 0 + -3.2

-2y = 0 + -3.2

Combine like terms: 0 + -3.2 = -3.2

-2y = -3.2

Divide each side by '-2'.

y = 1.6

Simplifying

y = 1.6

Step-by-step explanation:
