12) -6n – 20 = -2n +4(1 – 3n) What’s the first step

Mathematics
1 answer:
EastWind [94]3 years ago
4 0

Answer:

n = 3

Step-by-step explanation:

-6n - 20 = -2n + 4 (1-3n)

First distribute the 4 (1-3n)

-6n - 20 = -2n + 4 - 12n

Combine like terms on the right side

-6n - 20 = -14n + 4

Get 'n' on one side by adding -6n to both sides

-20 = -8n + 4

Subtract 4 to both sides

-24 = -8n

Divide -8 to both sides

3 = n

A bin has 382 red, yellow, blue and green balls. It has three times as many red balls as yellow balls, 52 more blue balls than y
Ksivusya [100]

The bin containing 382 red, yellow, blue and green balls have a total of 32 green balls.

Let x represent the number of red balls, y represent the number of yellow balls and z represent the number of green balls.

Since ther is a total of 382 balls, hence:

x + y + z = 382   (1)

There is three times as many red balls as yellow balls:

y = 3x

3x - y = 0    (2)

52 more blue balls than yellow balls, hence:

z = y + 52

- y - z = -52    (3)

Solving equations 1,  2 and 3 gives x = 62, y = 186, z = 134

Hence there are 62 red balls, 186 yellow balls and 134 blue balls

Green balls = 62 - 30 = 32 balls

Which values are solutions to the inequality?
Lerok [7]

The solution of the inequality 3r ≤ 4r - 6 is  r ≥ 6.

<h3>How to solve inequality?</h3>

In Mathematics, the relationship between two values that are not equal is defined by inequalities.

An inequality have the symbol <, >, ≤ and ≥. Hence, the inequality can be solved as follows:

3r ≤ 4r - 6

subtract 4r from both sides of the inequality,

3r ≤ 4r - 6

3r - 4r ≤ 4r - 4r - 6

3r - 4r ≤ - 6

- r ≤ -6

divide both sides of the inequality by -1

Therefore, the solution is r ≥ 6
