Answer:

x=1

Step-by-step explanation:

To solve this question we will have to open the bracket first

So let's solve the question

5(2x-8)+15=-15

Bracket first

10x-40+15=-15

We will have to solve the question further

10x-25=-15

Add 25 to both sides

10x=10

Let's make x the subject of formula by dividing both sides by 10

x=1

Therefore x is 1

Answer:

x = 1

Step-by-step explanation:

5(2x - 8) + 15 = -15

Subtract 15 both sides

5(2x - 8) = -30

Divide both sides by 5

2x - 8 = -6

Add 8 both sides

2x = 2

Divide both sides by 2

x = 1

almond37 [142]

35300 tons of sugar beet we need in order to get 7,413 tons of sugar.

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

Given that  in sugar beet, there is 21% of sugar.  Need to find out how much sugar beet we need in order to get 7,413 tons of sugar. Let we need x tone of sugar beet. So, according to the asked data, we have

                        21 \% \text { of } x=7413

                        \frac{21}{100} \times x=7413

                        0.21 \times x=7413

                        x=\frac{7413}{0.21}

                        x = 35300 tones

First order equations include linear equations. In the coordinate system, the linear equations are defined for lines. A linear equation in one variable is one in which there is a homogeneous variable of degree 1 (i.e., only one variable). Multiple variables may be present in a linear equation. Linear equations in two variables, for example, are used when a linear equation contains two variables. Examples of linear equations include 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, and 3x - y + z = 3.

Total books borrowed = 8+4 = 12

No. of non - fiction books = 7

No. of fiction books = 12 -7

                                    = 5
