Answer: x = -7

Step-by-step explanation:

4(1 - x) + 2x = -3(x + 1)

First, use distributive property

4 - 4x + 2x = -3x + -3

Combine like terms

4 - 2x = -3x - 3

Add 3x to each side

4 + x = -3

Subtract 4 from each side

x = -7

Answer:

-2

<h2>Step-by-step explanation:</h2>

1. Equation at the end of step 1  ((4•(1-x))+3x)-(0-2•(x-1))  = 0

2. Equation at the end of step 2 (4 • (1 - x) +  3x) -  -2 • (x - 1)  = 0

3. Equation at the end of step 3  x + 2  = 0

4. End of equation Solve  :    x+2 = 0

As a sales person Jonathan is paid 50 per week +3% of the total Amount he sells. This week he wants to earn at least 100. Write
steposvetlana [31]

Answer:

The Inequality with integer coefficient for the total sales is 5000+3x\geq 10000

Hence Jonathan should make total sales of at least <u>1667</u> to earn at least 100.

Step-by-step explanation:

Given:

Amount paid per week = 50

Addition amount = 3% of Total sales.

Let the Total sales be 'x'.

∴ Additional amount = \frac{3}{100}x

Amount he wants to earn this week  \geq 100

We need to write the inequality with integer coefficient for the total sales and also to find the total sales.

Solution:

We cans say that;

Amount paid per week plus Additional amount should be greater than or equal to Amount he wants to earn this week.

framing in equation form we get;

50+\frac{3}{100}x\geq 100

Now we will make the denominator common using LCM we get;

\frac{50\times100}{100}+\frac{3}{100}x\geq 100

\frac{5000}{100}+\frac{3}{100}x\geq 100

\frac{5000+3x}{100}\geq 100

Multiplying both side by 100 we get;

100 \times\frac{5000+3x}{100}\geq 100\times 100\\\\5000+3x\geq 10000

Hence The Inequality with integer coefficient for the total sales is 5000+3x\geq 10000

On solving the above equation we get;

Subtracting both side by 5000 we get;

5000+3x-5000\geq 10000-5000\\\\3x\geq 5000

Dividing both side by 3 we get;

\frac{3x}{3}\geq \frac{5000}{3}\\\\x\geq 1666.67

Hence Jonathan should make total sales of at least <u>1667</u> to earn at least 100.

Hoochie [10]
Based on the given information, let x represent the grade for the fifth quiz.

(79+88+95+71+x)/5=85
(333+x)/5=85
333+x=425
x=92

Jackson would have to earn a 92 on his fifth quiz to earn an average of 85.
