Answer:
[tex]x = - 10[/tex]
Step-by-step explanation:
1. simplify 2x + -3 to 2x - 3.
[tex]2x - 3 = - 23[/tex]
2. Add 3 to both sides.
[tex]2x = - 23 + 3[/tex]
3. simplify -23 + 3 to -20.
[tex]2x = - 20[/tex]
4. Divide both sides by 2.
[tex]x = - \frac{20}{2} [/tex]
5. Simplify 20/2 to 10.
[tex]x = - 10[/tex]
Therefor the answer is, x = -10

Answer:
15 degrees
Step-by-step explanation:
So you know that the sum of the two angles is 90 degrees, so you can make an equation:
[tex]3x + 45 =90[/tex]
Then, solve:
subtract 45 from both sides
[tex]3x = 45[/tex]
divide both sides by 3
[tex]x = 15[/tex]
This means that x = 15 degrees
Answer:
The answer is 15 degrees.
Step-by-step explanation:
1) Do you see the little square symbol at the bottom right corner? That represents that the angle is a right angle, or a 90 degree angle, in other words.
2) If you know that the first part of the angle is 45 degrees, as it is already labeled, then subtract 90 degrees - 45 degrees = 45 degrees, which is the angle that is left.
3) Set 3x equal to 45 degrees, and solve.
4) So, the equation is 3x = 45; divide by 3 on both sides to get x = 15 degrees.

C. Two vectors are said to be parallel if they point in the same direction or if they point in
opposite directions.
i. Are the vectors = < 1> and = <--1> parallel? Show your work and explain.
Type your response here:
ii. Are the vectors = <2, 3> and = <-3, -2> parallel? Show your work and explain.
Type your response here:
Answer:
Hey there,
The answer is below!!
Step-by-step explanation:
Knowing that those vectors start at the point (0,0) we can "think" them as lines.
As you may know, two lines are parallel if the slope is the same, then we can find the "slope" of the vectors and see if it is the same.
A) the vectors are: (√3, 1) and (-√3, -1)
You may remember that the way to find the slope of a line that passes through the points (x1, y1) and (x2, y2) is s = (y2 - y1)/(x2 - x1)
Because we know that our vectors also pass through the point (0,0)
then the slopes are:
(√3, 1) -----> s = (1/√3)
(-√3, -1)----> s = (-1/-√3) = (1/√3)
The slope is the same, so the vectors are parallel.
Part B:
The vectors are: (2, 3) and (-3, -2)
the slopes are:
(2, 3) -----> s = 3/2
(-3, -2)----> s = -2/-3 = 2/3
the slopes are different, so the vectors are not parallel.

Step-by-step explanation:
Roger gets $40 per day as wages and $4.50 as commission for every pair of shoes ne sells in a day. His daily
earnings goal is $112.
Write an equation to determine how many pairs of shoes, D, Roger must sell in a day to meet his daily earnings
goal
Answer:
Equation : y = 4.50D + 40
Number of pairs = 16
Step-by-step explanation:
It is given that:
Per day wage of Roger = $40
Commission on per pair of shoes = $4.50
Daily goal = $112
Number of pairs of shoes = D
Total earning = y
y = 4.50D + 40
112 = 4.50D + 40
4.50D = 112 - 40
4.50D = 72
Dividing both sides by 4.50
[tex]\frac{4.50D}{4.50}=\frac{72}{4.50}\\D = 16 \\[/tex]
Therefore,
Equation : y = 4.50D + 40
Number of pairs = 16

help please! answer correctly for brainliest . ( look at picture for problem )
Answer:
The slope is -2.
Step-by-step explanation:
1) The equation for a slope is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex].
2) Plug in x and y values into the equation. I plugged in (3,0) and (8,-10) into the equation.
3) You end up with: [tex]\frac{-10 -0}{8-3}[/tex], which simplifies down to [tex]\frac{-10}{5}[/tex], which equals -2.
Hope this helps! Feel free to give me Brainliest if you feel this helped. Have a good day, and good luck on your assignment. :)

the scale map says that 10cm represents 2km what distance on the map in centimeters represent an actual distance of 15 kilometers
Answer:
75cm
Step-by-step explanation:
Well, I can't see a photo, so I'll have to assume that the description provides enough info.
10cm/2km = x/15km,
where x is the distance on the map (in centimeters) of a real-life distance of 15 kilometers.
10cm/2km = x/15km
10/2 = 5/1
This means we have to multiply 5 by 15 to find x.
x = 5 · 15
x = 75
Let's plug the new value back in...
10cm/2km = x/15km
10cm/2km = (75cm)/15km
(Simplify each side to its simplest form)
10cm/2km = 75cm/15km
5/1 = 5/1
It works! So x = 75cm.
Hope this helps! :)
Saniya bought a new outfit for the holidays. She paid $15.00 for the shirt, $32.00 for the pants and $75.00 for the shoes. If she had a 30% off coupon, how much was her subtotal?
Answer:
$99.5
Step-by-step explanation:
Add up all the dollar amounts and subtract 30%
Answer:
Subtotal: $122 Total: $36.60
Step-by-step explanation:
Since you're only looking for the subtotal and not the actually total, you just have to add $15.00 + $32.00 + $75.00 and you should get $122. Although if you were looking for the total then you would have to know what 30% of 122 is and you should get 36.60 as the result so it would cost $36.60
Hope this helps you :D
