Step-by-step explanation:
if you say 1<2 and multiply both by negative 3 you will have -3 > -6
Answer:
Step-by-step explanation:
When you multiply both sides by a negative value you make the side that is greater have a "bigger" negative number, which actually means it is now less than the other side! This is why you must flip the sign whenever you multiply by a negative number. You can also consider this with a number line.

Wesley wants to have at least $50 to spend each day of his 7-day vacation. He plans to save $30 each month for 12 months. Which of the following shows that Wesley will save enough money for his vacation? Choose all that apply.
Answer:
i cant choose any that applies to this question because there is no picture added to it and there are no choices to choose from. If i were to solve it though, it would be; yes, he will save enough money for his vacation.
Step-by-step explanation:
I know he would have enough--and in this case more than enough, because since he's planning to save $30 for a whole year just for $50, when he could simply make $60--which is in fact more than needed for his goal-- in just 2 months. If he were to stick with his plan though, he'd make $360. I got that by multiplying 30 by 12.

For the equation, decide if it is always true or never true.
2(x + 3) = 5x + 6 − 3x
Answer:
always true
Step-by-step explanation:
Given
2(x + 3) = 5x + 6 - 3x ← distribute left side
2x + 6 = 2x + 6
Since both sides are equal then any real value of x is a solution.
Thus the equation is always true
Acela Express, the fastest train between Washington D.C and Boston covers a distance of 455 miles in 7 hours. How many miles will the train travel in 4 hours?
Answer:
260 miles
Step-by-step explanation:
Given that:
Distance covered in 7 hours = 455 miles
Number of miles train will travel in 4 hours
Average travel speed per hour :
Distance traveled / time taken
455 miles / 7 hours
= 65 miles per hour
Number of miles traveled in 4 hours :
Average Speed per hour * time
(65 * 4) = 260 miles

Find the absolute value.
17.-|8|
18. |13|
19. |3 6/7|
20. |-134|
please help i dont know how to do this. I just went back to in person school and I told her it never taught me this. she argued with me and basically teach myself from pages of the math book. and I figured out some stuff but im confused with this part I'd love it if you'd help.
An absolute value is the positive value of the number between the vertical lines.
If the number in between the vertical lines is negative, the absolute value become a positive.
If the value in between the lines is already positive, it stays positive.
17. |-8| = 8
18. |13| = 13
19. |3 6/7| = 3 6/7
20. |-1.34| = 1.34
Answer:
17. 8
18.13
19. 3 6/7
20. 1.34
Step-by-step explanation:
The absolute value would just be the opposite of the original value.

Suzy has a collection of quarters and dimes. Together she has 34 coins worth $6.40. How many quarters and how many dimes does Suzy have?
Please show your work :)
Answer:
Quarters = 20
Dimes = 14
Step-by-step explanation:
Dime = x = 10 cent = $0.1
Quarter = y = 25 cent = $0.25
x + y = 34 - - - (1)
0.1x + 0.25y = 6.40 - - - - (2)
From (1)
x = 34 - y
0.1(34 - y) + 0.25y = 6.40
3.4 - 0.1y + 0.25y = 6.40
3.4 + 0.15y = 6.40
0.15y = 6.40 - 3.40
0.15y = 3
y = 3 / 0.15
y = 20
x = 34 - y
x = 34 - 20
x = 14
Quarters = 20
Dimes = 14

Answer:
- 8
Step-by-step explanation:

Write each percent as a decimal and as a fraction in simplest form. 36. 200% 37. 135% 38. 152% 39. 0.03% 40. 0.45%
Answer:
2.0 , 2/1.
1.35 , 1 7/20.
1.52, 1 13/25
0.0003, 3/10000
0.0045, 9/2000
Step-by-step explanation:
1.35 = 1 35/100 = 1 7/20
1.52 = 1 52/100 = 1 13/25
0.0045 = 45/10000 = 1 9/2000.

what is the slope of the line
2x+12y-192
Answer:
-1/6
Step-by-step explanation:
To get the slope we need the equation in the form y=mx+c, and m is the slope.
2x+12y=192
12y = -2x + 192
y = -2/12 x + 16
-2/12 is the slope but this can be simplified to -1/6

Answer:
(-4,2)
Step-by-step explanation:
The line going horizontal is the X-axis. And they line going up and down is the y-axis. The way you write the location of a point is (X,Y). Hope this helps!!
Part A:
Draw arrows on the graph below for RISE and RUN. *Remember to start at the left point.*
Part B: Find the slope of the line from the graph above. *Don't forget to simplify!*
Answer:
Option D
Step-by-step explanation:
A). From the graph attached,
Arrow AB represents the RISE and arrow BC represents the RUN.
B). RUN from point A to B (Horizontal distance) = 2 units
Rise from point A to B (Vertical distance) = -4 [Since, downwards arrow represents negative notation]
Slope of the line segment AB = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]
= [tex]\frac{-4}{2}[/tex]
= -2
Therefore, slope of the line = slope of the line segment AB = -2
Option D will be the correct option.
Find the number of sides of a regular polygon if one interior angle is 120 degrees.
A.4
B.6
C.3
D.5
Answer:
B. 6 sides
Step-by-step explanation:
Interior angles of a n side Regular Polygon = (180n – 360) / n
120 = (180n – 360) / n
120n =180n - 360
180n - 120n = 360
60n = 360
n = 6
check: sum of interior angles of 6 side polygon: 180 * (6-2) = 720
720/6 = 120
Help please!!! ASAP!!! Currently failing!! ✌️
Answer:
1. x = 21°
2. x = 30°
3. x = 7°
5 x = 3
Step-by-step explanation:
Solving for x
1. 15+ 5x + 60° = 180°
75 + 5x = 180°
5x = 180 - 75
5x = 105
x = 105/5
x = 21°
2. These angle are vertical angles
Hence:
13x - 5 = 125°
13x = 125° + 5
13x = 130
x = 130/3
x = 30°
3. 8x - 1 = 55°
8x = 55 + 1
8x = 56
x = 56/8
x = 7°
5. These angles are angles in a straight line
17x - 1 + 130° = 180°
17x + 129° = 180°
17x = 180° - 129°
17x = 51
x = 51/17
x = 3°

find the equation of a line which passes through (2 4) with a slope of ½
Answer:
The equation of the straight line is x - 2y +6 =0
Step-by-step explanation:
Explanation:-
Given a point ( 2, 4) and slope m = [tex]\frac{1}{2}[/tex]
The equation of the straight line passing through the point and having slope 'm'
y - y₁ = m ( x - x₁)
y - 4 = [tex]\frac{1}{2}[/tex] ( x - 2)
2( y -4) = ( x-2)
2 y - 8 = x -2
x - 2 y - 2 + 8 =0
x - 2y + 6 =0
The equation of the straight line is x - 2y +6 =0
The answer is:
y = 1/2x + 5
Work/explanation:
Since I have a point and the slope, I will write the equation in point slope form.
Point slope is
[tex]\sf{y-y_1=m(x-x_1)}[/tex]
where m = slope and (x₁, y₁) is a point on the line
Plug in the data
[tex]\sf{y-4=\dfrac{1}{2}(x-2)}[/tex]
Now let's simplify to slope intercept
[tex]\large\begin{gathered}\sf{y-4=\dfrac{1}{2}x+1}\\\sf{y=\dfrac{1}{2}x+1+4}\\\sf{y=\dfrac{1}{2}x+5}\end{gathered}[/tex]
Hence, the equation is y = 1/2x + 5.
