Answer:
-9
Step-by-step explanation:
5x-3x=-10-8
2x= -18
x=-18/2
= -9
Solution of the expression is,
⇒ x = - 9
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
Equation is,
⇒ 5x + 8 - 3x = -10
Now, We can simplify as;
⇒ 5x + 8 - 3x = -10
⇒ 2x = - 10 - 8
⇒ 2x = - 18
⇒ x = - 18/2
⇒ x = - 9
Thus, Solution of the expression is,
⇒ x = - 9

Melanie is reading a book that has 577 pages. She has already read 187 pages of the book and will read an additional 26 pages per night. Solve 187 + 26n = 577 to find how many more nights it will take Melanie to finish the book.
Answer:
15 nights
Step-by-step explanation:
187+26n=577
-187 -187
26n=390
divide 26 on both sides

Brianna answered 80% of the questions correct on her math test. Which fraction represents the number of questions she answered correctly?
Answer: 4/5
Step-by-step explanation:
80% is 80/100
80/100 simplified is 4/5
Answer:
8/10 ( you didnt say how much questions there were)
Step-by-step explanation:
As a fraction, 80/100 simplifies to be 8/10. ( 10 can go into 80, 8 times and 10 can go into 100, 10 times)
So, if Brianna had 10 questions on the test and answered 80% correctly, take the numerator of this simplified fraction and that's the answer

x^4-16
Answer:
x - 2Step-by-step explanation:
We will find the fourth root of both sides, which for x⁴ is simply going to be 4. For the other side, we will need to find the 4th root of 16. This can found in one of two ways.
Take the square root of 16, which and 4, and square root it again to get 2.
Use the calculator to find the 4th root of 16, which also comes out to be 2.

Use a triple integral to find the volume of the given solid. The tetrahedron enclosed by the coordinate planes and the plane 2x + y + z = 2
Answer:
[tex]\mathbf{V = \dfrac{2}{3}}[/tex]
Step-by-step explanation:
Consider the tetrahedron enclosed by the coordinate planes and the plane 2x + y + z = 2
Let A be the region obtained by projecting the volume(V) onto the xy-plane.
Similarly, the plane 2x + y + z = 2 intersects with the xy-plane in y = 2 - 2x.
Using the vertical strips, the region A is to the xy-plane can be expressed as:
[tex]A = \{(x,y) | 0 \le x \le 1, 0 \le y \le 2 - 2x\}[/tex]
Thus, the volume of the solid can be calculated as follows;
[tex]V = \int^1_0 \int ^{2-2x}_{0} \int ^{2-2x-y}_{0} \ dz \ dy \ dx[/tex]
[tex]V = \int^1_0 \int ^{2-2x}_{0} (2-2x-y) \ dy \ dx[/tex]
[tex]V = \int^1_0 \bigg [2\times y -2x\times y - \dfrac{y^2}{2} \bigg]^{2-2x}_{0} \ dx \[/tex]
[tex]V = \int^1_0 \bigg [2\times (2-2x) -2x\times (2-2x) - \dfrac{(2-2x)^2}{2} \bigg]\ dx[/tex]
[tex]V = \int^1_0 \bigg [2x^2-4x+2 \bigg]\ dx[/tex]
[tex]V = \bigg [2\dfrac{x^3}{3}-\dfrac{4x^2}{2}+2 x\bigg]^1_0[/tex]
[tex]V = \bigg [2\dfrac{(1)^3}{3}-\dfrac{4(1)^2}{2}+2 (1)-0\bigg][/tex]
[tex]V = \dfrac{2}{3}- 2 + 2[/tex]
[tex]\mathbf{V = \dfrac{2}{3}}[/tex]

Answer:
132°
Step-by-step explanation:
y°=7x+20° (vertically opposite angles)
3x°+7x°+20°=180° (interior angles, since M is parallel to N)
10x+20°=180°
10x=180°-20°
10x=160°
x=16°
y°=7(16°)+20°
y°=112°+20°
y°=132°
To eliminate the y terms and solve for x in the fewest steps, by which constants should the equations be multiplied by before adding the equations together?
First equation: 4x − 3y = 34
Second equation: 3x + 2y = 17
The first equation should be multiplied by 2 and the second equation by 3.
The first equation should be multiplied by 2 and the second equation by −3.
The first equation should be multiplied by 3 and the second equation by 4.
The first equation should be multiplied by 3 and the second equation by −4.
The possible answer is the first choice because thats how you do a equation
The first equation should be multiplied by 2 and the second equation by 3 and then we can add since the sign are different,.

When graphing on the complex plane, which
quadrant will the complex number10 – 13i be
found in?
Given :
A complex number z = 10 - 13i .
To Find :
Which quadrant will the complex number (10 - 13i) be found.
Solution :
Coefficient of real part of complex number, r = 10.
Coefficient of imaginary part of complex number, i = -13.
Since, the coefficient of imaginary part is -ve and real part is +ve .
Therefore, the complex number is in 4th quadrant.
Hence, this is the required solution.
When graphing on the complex plane, the complex number will be in the 4th quadrant.
The standard form of expressing complex numbers is expressed z = x + iy
x is the real axis (x-axis on the coordinate point)
y is the imaginary axis (y-axis on the coordinate plane)
Given the complex number z = 10 - 13i, this shows that the imaginary axis is a negative value while the real axis is a positive value.
This shows that when graphing on the complex plane, the complex number will be in the 4th quadrant.
