A is x=7.5 and B) is x=1
sergeinik [125]2 years ago
5 0

Step-by-step explanation:

a⟩. (4x - 1)/2 = x + 7

⇛(4x - 1)/2 = (x+7)/1

By doing cross multiplication, we get

⇛1(4x - 1) = 2(x + 7)

⇛4x - 1 = 2x + 7

⇛4x - 2x = 7-1

⇛2x = 6

⇛x = 6÷2 = 6/2

∴ x = 3 Ans.

b⟩. 3x + 2 = (2x + 13)/3

⇛(3x + 2)/1 = (2x + 13)/3

⇛3(3x + 2) = 1(2x + 13)

⇛9x + 6 = 2x + 13

⇛9x - 2x = 13-6

⇛7x = 7

⇛x = 7÷7 = 7/7

∴ x = 0 = 1 Ans.

If you have any doubt, then you can ask me in the comments.

Subtract (8.4 x 108) − (9.5 x 106).
Step2247 [10]

Based on the fact that the expressions to be subtracted have the same base, the result is 8.305 x 10⁸.

<h3>What is the result of the subtraction?</h3>

The first number in standard form is:

= 8.4 x 10⁸

= 840,000,000

The second number in standard form is:

= 9.5 x 10⁶

= 9,500,000

The result is:

= 840,000,000 - 9,500,000

= 830,500,000

In scientific notation this is:

= 8.305 x 10⁸

What is 3x^2-2n-5=0<br> please help me!!!
expeople1 [14]
The answer to your question is: 
It is a quadratic equation in 'x', with 'n' mistakenly typed in the second term..

Although you didn't ask for the solutions to the equation, I'm already here
so I might as well go through it and find them:

<span><u>3x² - 2x - 5 = 0</u></span>

In terms of the generic quadratic formula:
A = 3
B = -2
C = -5

Plug those into the quadratic formula, and you discover that

<u>x = -1</u>
and
<u>x = ⁵/₃</u>
