Answer:

(4x + 3)/11

Explanation:

2y -x = 3/4(-y + 1) Multiply both sides by 4

8y – 4x = 3(-y + 1) Remove parentheses

8y – 4x = -3y + 3 Add 3y to each side

11y -4x = 3 Add 4x to each side

11y = 4x + 3 Divide both sides by 11

y = (4x + 3)/11

Answer:

Step-by-step explanation:

We know that a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse

5^2 + 12^2 = c^2

25+144 = c^2

169 = c^2

Taking the square root of each side

sqrt(169) = sqrt(c^2)

13 =c

The height of a distance marker is 8 2/13 feet. 4/5 of the pole is painted white and rest is painted blue. How much of the pole

Mashcka [7]

1) Convert the mixed number 8 and 2/13 into a fraction:

8 and 2/13 = 8 + 2/13 = (8*13 + 2) / 13 = 106 / 13

2) Calculate 4/5 of 106 / 13

(4 / 5) * ( 106 / 13) = (4*106) / (5*13) = 424 / 65

That is (390 + 34) / 65 = 390/65 + 34/65 = 6 + 34/65 is painted white

3) Calculate the rest

(1/5) * (106 / 13) = 106 / 65 = 1 + 41/65 is painted blue

Seven x's and 3y's cost as much as 4z's. One z costs as much as 1x plus 1y together. How many x's cost as much as 1y?

Pie

Answer:

Step-by-step explanation:

Equations

7x + 3y = 4z

<em>Second equation</em>

x + y = z Multiply the entire equation by 4

4[x + y = z] Now distribute the 4 through the equation

4x + 4y = 4z Both equations = 4z. Equate the lefts.

<em>Third equation </em>

7x+3y = 4x + 4y Subtract 3y from both sides

7x + 3y -3y = 4x + 4y -3y

7x = y + 4x Subtract 4x from both sides

7x - 4x = y + 4x - 4x Combine

3x = y

Answer: 3x = y

Hey can you please help me posted picture of question

Sergeeva-Olga [200]

Total number of chips = 4+ 6 = 10
Number of white chips = 4

Probability of picking a white chip = $\frac{4}{10}= \frac{2}{5}$

This white chip is not replaced back into the bag. This will reduce the number of white chips in the bag by 1 and reduce the total number of chips in the bag by 1.

So, now the total number of chips in the bag = 3 + 6 = 9
Number of white chips in the bag = 3

Probability of picking a white chip = $\frac{3}{9}= \frac{1}{3}$

Thus, the probability of picking two white chips will be = $\frac{2}{5}* \frac{1}{3}= \frac{2}{15}$

Therefore, option B gives the correct answer.
