Answer:
-29
Step-by-step explanation:
4× (x+6) = -5. + 3x
4 times the sum of a number is 5 less than 3 times the same number
4×(x+6) = 3x - 5
4x + 24 = 3x - 5

How many ways can you make change for 60¢ using only nickels, dimes, and quarters?
There are 13 ways to make change for 60¢ using only nickels, dimes and quarters.
Determination of the number of combinations for a given amount of moneyIn 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:
Case 1 ([tex]q = 0[/tex])[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.
Case 3 ([tex]q = 2[/tex])[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]

Determine whether (a) x = -1 or (b) x = 2 is a solution to this equation
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

solve for r
A= 3r(to the 2 power) i couldn’t make it a small two
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]$A=3r^{2}[/tex]
We have to solve for r.
Solve for x : [tex]$x^{2} = 9[/tex]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].

Calculate the derivative using implicit differentiation:
∂w /∂z,x^(5)w+w^7+wz^2+8yz=0
∂w/ ∂z= ?
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.
What is implicit differentiation?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.

Divide both sides of the inequality by 3.
Answer:

Step-by-step explanation:
-15<-6=-15
-15÷3
=-5
Inequalities are used to show unequal expressions. There are five inequalities, and they are: not equal to, greater than, less than, greater than or equal to and less than or equal to.
The inequality when both sides of [tex]-15 < -6[/tex] is divided by 3 is [tex]-5< -2[/tex]
Given that:
[tex]-15 < -6[/tex]
Divide both sides by 3
[tex]-15 \div 3< -6 \div 3[/tex]
Evaluate the division
[tex]-5< -2[/tex]
Hence, the inequality when both sides of [tex]-15 < -6[/tex] is divided by 3 is [tex]-5< -2[/tex]

Find the value of x for which ABCD must be a parallelogram.
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
