Answer: (a) x = -1

Step-by-step explanation:

Given

-2 (x - 1) = 1 - 3x

Expand parentheses and apply the distributive property

(-2) · x - (-2) · 1 = 1 - 3x

-2x + 2 = 1 - 3x

Add 3x on both sides

-2x + 2 + 3x = 1 - 3x + 3x

x + 2 = 1

Subtract 2 on both sides

x + 2 = 1 - 2

Answer:

ans is 7

Step-by-step explanation:

as we know that angle B and C are equal cause it is an alternative angle so

3x-17=25-3x

so 3x+3x=25+17

6x=42

x=7

Answer:

7

Step-by-step explanation:

The value of x only makes the figure a llgm because the question says so. It needs one more fact to be a llgm.

That said, you are 1/3 the way there. Those angles marked must be equal.

3x - 17 = 25 - 3x            Add 3x to both side

3x + 3x - 17 = 25           Combine

6x - 17 = 25                   Add 17 to both sides

6x = 25 + 17                  Combine

6x = 42                         Divide by 6

6x /6 = 42/6

x = 7

There are 13 ways to make change for 60¢ using only nickels, dimes and quarters.

In the United States of America, a nickel equals 0.05 dollar, a dime equals 0.10 dollar and a quarter equals 0.25 dollar.  

For 0.60 dollar we have the following expression in terms of nickels ([tex]n[/tex]), dimes ([tex]d[/tex]) and quarters ([tex]q[/tex]):

[tex]0.25\cdot q + 0.10\cdot d + 0.05\cdot n = 0.60[/tex], where [tex]q,\,d,\,n \in \mathbb{N}_{O}[/tex] (1)

Since quarters are the money of greatest value, we assume arbitrary quantities and count corresponding solutions, whose representations are included below:

[tex]n = 12-2\cdot d[/tex] (2)

According to the first graph, there are seven forms in this scenario.

Case 2 ([tex]q = 1[/tex])

[tex]n = 7-2\cdot d[/tex] (3)

According to the graph case_2, there are four forms in this scenario.

[tex]n = 2- 2\cdot d[/tex]

According to the graph case_3, there are two forms in this scenario.

Hence, there are 13 forms to make change for 60¢ using only nickels, dimes and quarters. [tex]\blacksquare[/tex]

Answer:

x = 36

Step-by-step explanation:

multiply 4 and 9.5 to get the total amount.

38 = 14.5 + (-8) + (-4.5) + x; hence x is 36.

Answer: x=36

Step-by-step explanation:

To solve this question, we first want to know what mean is. Mean is the same as the average. You take the sum and divide it by the amount. Since we know there are 4 numbers and the mean, we can easily find the value of x.

[tex]\frac{14.5-8-4.5+x}{4} =9.5[/tex]               [multiply both sides by 4]

[tex]14.5-8-4.5+x=38[/tex]       [combine like terms]

[tex]2+x=38[/tex]                          [subtract both sides by 2]

[tex]x=36[/tex]

Now, we know that x=36.

Answer:

Step-by-step explanation:

Given: [tex]x^5w + w^7 + wz^2 + 8yz = 0[/tex]

Taking the partial derivative of the above equation with respect to z, we get

[tex]x^5\dfrac{\partial{w}}{\partial{z}} + 7w^6\dfrac{\partial{w}}{\partial{z}} + z^2\dfrac{\partial{w}}{\partial{z}} + 2z + 8y =0[/tex]

Collecting all terms containing [tex]\frac{\partial{w}}{\partial{z}},[/tex] we get

[tex](x^5 + 7w^6 + z^2)\dfrac{\partial{w}}{\partial{z}} = -2(z + 4y)[/tex]

Then

[tex]\dfrac{\partial{w}}{\partial{z}} = \dfrac{-2(z + 4y)}{x^5 + 7w^6 + z^2}[/tex]

The derivative using implicit differentiation can be calculated and after rearranging the terms.

Implicit differentiation is the technique in which the derivative of y with respect to x using implicit differentiation without having to solve the supplied equation for y.

We have:

[tex]\rm x^5w+w^7+wz^2+8yz=0[/tex]

We have to find the:

= ∂w/ ∂z

[tex]\rm \dfrac{\partial }{\partial z}[\rm x^5w+w^7+wz^2+8yz=0][/tex]

[tex]\rm x^5\dfrac{\partial w}{\partial z} +7w^6\dfrac{\partial w}{\partial z}+z^2\dfrac{\partial w}{\partial z}+2z+8y=0[/tex]

After rearranging the terms:

[tex]\rm (x^5 +7w^6+z^2)\dfrac{\partial w}{\partial z}= -2(z+4y)[/tex]

[tex]\rm \dfrac{\partial w}{\partial z}= \dfrac{-2(z+4y)}{x^5 +7w^6+z^2}[/tex]

Thus, the derivative using implicit differentiation can be calculated and after rearranging the terms.

Answer:

r = [tex]\sqrt{\frac{a}{3}}[/tex]

Step-by-step explanation:

1. A = 3r²

(Divide 3 by both sides)

2. A/3 = r²

(Square root both sides)

√A/3 = r

On solving for 'r' we get -  r = [tex]\sqrt{\frac{A}{3} }[/tex].

We have the following expression -

[tex]$A=3r^{2}[/tex]

We have to solve for r.

On solving, we get -

x = [tex]$\pm\sqrt{9}[/tex]

x = [tex]$\pm3[/tex]

According to the question, we have -

[tex]$A=3r^{2}[/tex]

[tex]$r^{2} = \frac{A}{3}[/tex]

r = [tex]\pm\sqrt{\frac{A}{3} }[/tex]

Since, the area cannot be negative, therefore -

r = [tex]\sqrt{\frac{A}{3} }[/tex]

Hence, on solving for 'r' we get -  r = [tex]\sqrt{\frac{A}{3} }[/tex].
