Answer:

$\frac{1}{3}x - 4x$

Step-by-step explanation:

La tercera parte = 1/3

Cuando dicen "de un número" se refieren a una literal (variable) = X

Y el cuádruple de un número = 4X

Answer:

$x = - 6$

$x = 12$

$x = 8$

$x = - 21$

$x = 18$

$x = - 2$

$x = 40$

$x = - 3$

$x = -21$

$x = 2$

$x = - 18$

$x = - 7$

$x = 6$

$x = 10$

$x = 3$

Step-by-step explanation:

$1.$

$- 7x + 16 = 58$

$- 7x = 58 - 16$

$- 7x = 42$

$\frac{ - 7x}{ - 7} = \frac{42}{ - 7}$

$x = \frac{ 42}{ - 7}$

$x = - 6$

$2.$

$- 2x + 15 = - 9$

$- 2x = - 9 - 15$

$- 2x = - 24$

$\frac{ - 2x}{ - 2} = \frac{ - 24}{ - 2}$

$x = \frac{ - 24}{ - 2}$

$x = 12$

$3.$

$5x - 4 = 36$

$5x = 36 + 4$

$5x = 40$

$\frac{5x}{5} = \frac{40}{5}$

$x = \frac{40}{5}$

$x = 8$

$4.$

$25 - 3x = 88$

$- 3x = 88 - 25$

$- 3x = 63$

$\frac{ - 3x}{ - 3} = \frac{63}{ - 3}$

$x = \frac{63}{ - 3}$

$x = - 21$

$5.$

$- 11 = 7 - x$

$7 - x = - 11$

$- x = - 11 - 7$

$- x = - 18$

$\frac{ - x}{ - 1} = \frac{ - 18}{ - 1}$

$x = \frac{ - 18}{ - 1}$

$x = 18$

$6.$

$65 + 15x = 35$

$15x = 35 - 65$

$15x = - 30$

$\frac{15x}{15} = \frac{ - 30}{15}$

$x = \frac{ - 30}{15}$

$x = - 2$

$7.$

$\frac{1}{2} x - 18 = 2$

$\frac{1}{2} x = 2 + 18$

$\frac{1}{2} x = 20$

$\frac{1}{2} \times 2x = 20 \times 2$

$x = 40$

$8.$

$\frac{2}{3} x - 10 = - 12$

$\frac{2}{3} x = - 12 + 10$

$\frac{2}{3} x = - 2$

$x = - 2( \frac{3}{2} )$

$x = - 3$

$9.$

$6 - \frac{1}{3} x = - 1$

$- \frac{ 1}{3} x = - 1 - 6$

$- \frac{1}{3} x = - 7$

$x = - 7( - \frac{3}{1} x)$

$x = 21$

$10.$

$4 - 9 x= - 14$

$-9x = - 14 - 4$

$-9x = - 18$

$\frac{-9x}{-9} = \frac{ - 18}{-9}$

$x = \frac{ - 18}{-9}$

$x = 2$

$11.$

$11 - x = 29$

$- x = 29 - 11$

$- x = 18$

$\frac{ - x}{ - 1} = \frac{18}{ - 1}$

$x = \frac{ 18}{ - 1}$

$x = - 18$

$12.$

$- 9- 11 x= 68$

$- 11x = 68 + 9$

$- 11x = 77$

$\frac{ - 11x}{ - 11} = \frac{77}{ - 11}$

$x = \frac{77}{ - 11}$

$x = - 7$

$13.$

$45 + \frac{5}{6} x = 50$

$\frac{5}{6} x = 50 - 45$

$\frac{5}{6} x = 5$

$x = 5( \frac{6}{5} )$

$x = 6$

$14.$

$- 5x + 17 = - 33$

$- 5x = - 33 - 17$

$- 5x = - 50$

$\frac{ - 5x}{ - 5} = \frac{ - 50}{ - 5}$

$x = \frac{ - 50}{ - 5}$

$x = 10$

$15.$

$95 = - 4 + 33x$

$- 4 + 33x = 95$

$33x = 95 + 4$

$33x = 99$

$\frac{33x}{33} = \frac{99}{33}$

$x = \frac{99}{33}$

$x = 3$

Determine the equation of the circle graphed below.

Diano4ka-milaya [45]

Answer:

$(x - 6)^2 + (y - 2)^2 = 4$

Step-by-step explanation:

Required

The equation of the circle

The equation of a circle is:

$(x - h)^2 + (y - k)^2 = r^2$

Where:

$Center = (h,k)$

$radius \to r$

From the graph, we have

$(h,k) = (6,2)$

$r = 2$

So:

$(x - h)^2 + (y - k)^2 = r^2$ becomes

$(x - 6)^2 + (y - 2)^2 = 2^2$

$(x - 6)^2 + (y - 2)^2 = 4$

Hi can you help with some ratio and proportion questions

pochemuha

Answer:

1a. 12 : 40

1b. 15 : 21

1c. 24 : 44

1d. 2 : 25

2. 40 boys and 100 girls

3. 96 girls

4. £71.43

5a. 9 : 4

5b. 3 : 1

5c. 3 : 5

6. 210 : 90

7. Sorry, I couldn't figure out how to solve this question :(

Step-by-step explanation:

Since I'll be using a similar method to solve these questions, I won't go into a detailed explanation for how I solved every single question. If you do need extra help, please ask in the comments below my answer.

1. Let's use part (a) as an example. The ratio is 3:10. To new ratio is ?:40. So, 10 becomes 40. What number multiplied by 10 equals 40? The answer is 4. If 10 is multiplied by 4, then 3 must be multiplied by 4 as well. 3*4 = 12, so the ratio is 12:40.

In part b the ratio is multiplied by 3, part c is 4, and part d is 1/2.

2. To solve this, add the values on both sides of the ratio together: 2 + 5 = 7. Now, divide the total number of pupils, 140, by 7: 140/7 = 20. Finally, multiply 20 by both sides of the ratio: 2 * 20:5 * 20 = 40:100. There are 40 boys and 100 girls.

3. To solve this I used the same method as the one I used in question 1.

4. The ratio is 5:140, where 140 becomes 2000. To solve, use the method used in question 1.

5. Simplifying ratios is the same as simplifying fractions. Find the greatest common factor of the values on both sides of the ratio and divide both sides by that factor. For example, in part a the factor for 45:20 is 5. 45/5 = 9 and 20/5 = 4. The ratio becomes 9:4.

For part b the factor is 9 and for part c the factor is 50.

6. Same method as was used in question 2.

Hope this helps :)
