Answer:
5x+(-3x+11)=21
2x+11=21
2x=21-11
2x=10 2x/2=10/2
x=5
Answer:
X = 5
Step-by-step explanation:
here's your solution
=> y= -3x + 11.
=> given equation = 5x + y = 21
=> by putting value of Y in given equation
=> 5x -3x + 11 = 21
=> 2x + 11 = 21
=> 2x = 21-10
=> x = 10/2
=> x = 5

What is the expression for this word problem please help !!
A number added to 13 all divided by 2
Answer:
[tex]\frac{13+x}{2}[/tex]
Step-by-step explanation:
"A number" is the part of the question you don't know, and therefore is the variable. Let's call it [tex]x[/tex] from now on.
So, when you add a number to 13 it means you are increasing 13 by that number, or [tex]13+x[/tex].
To divide it all by 2, simply put the above expression on a fraction with a denominator of 2:
[tex]\frac{13+x}{2}[/tex]
And there is your answer.

salary of $51,000, and each year he receives
o $1,500 raise. How many years will it take
before Marshall and Jim earn the same
salary?
Equation:
Volue of x:
Answer:
equation: 36000 + 4000x = 51000 + 1500x
value of x: 6
Step-by-step explanation:
Marshall:
36000 + 4000x
Jim:
51000 + 1500x
36000 + 4000x = 51000 + 1500x
360 + 40x = 510 + 15x
25x = 150
x = 6
Answer:
equation: 36000 + 4000x = 51000 + 1500x
value of x: 6

Answer:
x -1
Step-by-step explanation:
The absolute value function is piecewise linear. When its argument is negative, it gives the opposite of that argument:
|x| = -x . . . for x < 0
|x| = x . . . for x ≥ 0
__
When the argument is some function of x, the same rules apply.
|x -1| = -(x -1) . . . for (x -1) < 0
|x -1| = x -1 . . . for x -1 > 0
The condition x-1 > 0 is equivalent to x > 1, so you have ...
|x -1| = x -1 . . . for x > 1
_____
The attached graph shows that |x-1| and x-1 are the same graph when x>1.

Answer:
y ≥ 1/4x + 2
Step-by-step explanation:
The line is solid, and the shading is above it, so the inequality will have a form similar to ...
y ≥ [the boundary line]
The y-intercept is y = 2, and the slope is 1 unit up for 4 units right, so 1/4. In slope-intercept form, the equation of the boundary line is ...
y = mx + b . . . . . . for slope m and y-intercept b
This boundary line has equation ...
y = 1/4x + 2
So, the inequality is ...
y ≥ 1/4x + 2

From her home, Glera traveled 5.8 miles north to the grocery stare, then 2.1 mlles west to the library. What is the distance thom her home to the library
Answer:
6.16 miles
Step-by-step explanation:
When solving word problems like these, I like to start by drawing a picture.
So, Glera starts at her home and moves north by 5.8 miles. Then, she walks west by 2.1 miles to the library. The problem wants you to find the distance from her home to the library.
I've attached a drawing I made to help me visualize the problem. The distance from her home to the library is the hypotenuse of the triangle. To solve for it, you would use the equation [tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex].
a and b are the sides of the triangle, and c is the hypotenuse.
[tex]5.8^{2}[/tex] + [tex]2.1^{2}[/tex] = [tex]c^{2}[/tex]
33.64 + 4.41 = [tex]c^{2}[/tex]
38.05 = [tex]c^{2}[/tex]
To find c, you would take the square root of 38.05, which is about 6.16 if you use a calculator.
So, the distance from her home to the library is 6.16 miles!
