3 (x + 2) + 4(x - 5) = 10

Simplify.

3x + 6 + 4x - 20 = 10

Add like terms.

(3x+4x) + (6-20) = 10

Simplify.

7x - 14 = 10

Add 14 to both sides of the equation.

7x = 24

Divide both sides by 7 so that X is by itself.

x = 24/7, or 3 3/7

~Hope I helped!~

How many solutions will this system of equations have? (2 points)
Agata [3.3K]
The answer is infinitely many solutions

If you divide the 2nd equation by 3, you get the first equation, meaning they are identical. That means that any value of x will be true, which means there are infinite solutions

Solve for w. | – w|≥2 Write a compound inequality like 1 < x < 3 or like x < 1 or x > 3. Use integers, proper fracti
Eduardwww [97]

Answer:

-2 \geq w \geq 2

Step-by-step explanation:

Given

|-w| \geq 2

Required

Solve for w

|-w| \geq 2

In absolution functions;

|-w| = |w|

So, the given expression can be rewritten as

|w| \geq 2

Removing the absolute sign, will gibe

w \geq 2 or w \leq -2

When the second inequality os rewritten, it gives

w \geq 2 or -2 \geq w

Reorder both inequalities

-2 \geq w or w \geq 2

Lastly, both inequalities are combined

-2 \geq w \geq 2

1.5/4x+1=0.4/x+4 PLEASE HELP ITS PROPORTIONS
Serhud [2]

Answer:

Proportion states that the two fractions or ratios are equal

Given the equation:  \frac{1.5}{4x+1} = \frac{0.4}{x+4}

By cross multiply we get;

1.5(x+4) = 0.4(4x+1)

Using distributive property; a\cdot (b+c) = a\cdot b+ a\cdot c

1.5x + 6= 1.6x + 0.4

Subtract 0.4 from both sides we get;

1.5x +5.6= 1.6x

Subtract 1.5x from both sides we get;

5.6= 0.1x

Divide both sides by 0.1 we get;

x = \frac{5.6}{0.1}

Simplify:

x = 56

Therefore, the value of x that satisfy the equation \frac{1.5}{4x+1} = \frac{0.4}{x+4} is, 56
