Answer:
See below.
Step-by-step explanation:
2(x-3) = 7x + 39
2x - 6 = 7x + 39
Subtract 2x from each side
-6 = 5x + 39
Subtract 39 from each side
-45 = 5x
Divide both sides by 5
-9 = x
What is the first step in solving: 19 + 8x = 91?
A. Simplify
B. Multiply by 8
C. Subtract 19
D. Divide by 8
Answer:
C. Subtract 19
Step-by-step explanation:
Answer:
Subtract 19 from each side
Step-by-step explanation:
19 + 8x = 91
Subtract 19 from each side
19-19 + 8x = 91 -19
8x = 72
Then divide each side by 8
8x/8 = 72/8
x = 9

A regular pentagon is centered about the origin. Which transformation
maps the pentagon onto itself?
a. A reflection across line m
b. A reflection across the x-axis
C.
d.
A clockwise rotation of 144 degrees about the origin
Answer:
The answer is D. A clockwise rotation of 144 degrees about the origin.
Step-by-step explanation:
In most cases; when an object is transformed, the position of the object changes. A clockwise rotation of 144 degrees about the origin will map the pentagon onto itself.
Given:
The attached pentagon
The number of sides (n) in a pentagon is:
[tex]n = 5[/tex]
The pentagon will not be mapped onto itself when reflected across line m because m is not at the center of the polygon
The pentagon will not be mapped onto itself when reflected across the x-axis because the pentagon has 5 sides (odd number of sides)
To map the pentagon onto itself, the pentagon has to be rotated.
The angle of rotation is:
[tex]\theta = \frac{360}n[/tex]
[tex]\theta = \frac{360}5[/tex]
[tex]\theta = 72[/tex]
Other possible angles of rotation must be a multiple of 72. i.e.
[tex]\theta = 72, 144, 216, 288....[/tex]
This means that: option (d) is correct because 144 is a multiple of 72
Hence, a clockwise rotation of 144 degrees about the origin will map the pentagon onto itself.

How to measure 4 tablespoons of butter
1⁄4 cup = 1⁄2 stick = 4 tablespoons = 2 oz. = 57g
1⁄2 cup = 1 stick = 8 tablespoons = 4 oz. (1⁄4 pound) = 113g
3⁄4 cup = 11⁄2 sticks = 12 tablespoons = 6 oz. = 170g
1 cup = 2 sticks = 16 tablespoons = 8 oz. (1⁄2 pound) = 227g
11⁄4 cups = 21⁄2 sticks = 20 tablespoons = 10 oz. = 284g
11⁄2 cups = 3 sticks = 24 tablespoons = 12 oz. (3⁄4 pound) = 341g
13⁄4 cups = 31⁄2 sticks = 28 tablespoons =14 oz. = 398g
2 cups = 4 sticks = 32 tablespoons = 16 oz. (1 pound) = 454g
The wrapping on each stick indicates tablespoon measures (8 tablespoons per stick). So if you are using cup measures you could pack the butter into a measuring cup or below is a ready reckoner which may help if you have scales. 1 stick butter = 8 tablespoons = 1/2 cup = 4 ounces/110g.
Common measurements:
1 kilogram = 2.2lbs
454 grams = 1lb = 16 oz
28.35 grams = 1 oz
1 tbsp = 15 ml
1 tsp = 5ml
1 tbsp = 3 tsp
4 tbsp = 1/4 cup
1 cup = 250ml = 8 fluid oz
1 fluid oz = 29.5 ml = 2 tbsp
1 pint = 2 cups
You could see that 4 tablespoons = 1/4, so you could pour and melt it in a measuring cup.

Please tell me where to graph this (its about slope)
Answer:
When it come to coordinates (x,y) x comes first then y. And when it comes to fractions rise/run rise is your numerator and run is your denominator.
y = 1/2x + b
3 = 1/2(4) + b

BRANILESS IF ANSWERED QUICK!! What is the measure, in degrees of angle x?
We can solve this by using linear pair.
Thus, x degree + 63.2 degree = 180 degree
= x degree= 180 degree - 63.2 degree
= x degree= 116.8 degree
= Thus x = 116.8 degree
Answer:
We can solve this by using linear pair.
Thus, x degree + 63.2 degree = 180 degree
= x degree= 180 degree - 63.2 degree
= x degree= 116.8 degree
= Thus x = 116.8 degree
An alien blob started with a mass of 18 kg and is doubling in size every day. How large will the blob be after 2 weeks? y= a(b).
Answer:
214kg
Step-by-step explanation:
We can use the equation [tex]f(x)=(x)^2+18[/tex] to model the blobs growth. There are 14 days in 2 weeks so if we plug in [tex]f(14)[/tex] that will give us [tex]f(14) = (14)^2+18\\f(14)=214[/tex] so the blob will be 214kg in 2 weeks.

What will be the coordinates of point A if figure ABCD is reflected across the x-axis?
The coordinates of points A are -2 and 5.
What is coordinate geometry?A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.
In the given image there is a rectangle ABCD on the coordinate axes. All the vertices of the rectangle are having coordinates. Point A of the rectangle is in the second quadrant where the value of y is positive but the value of x is negative. The coordinates of points A are -2 and 5.
Therefore, the coordinates of points A are -2 and 5.

In Orlando, Florida, there are an average of 24 days of rain each June. What percent of the month of June experiences rain?
Answer:
80%
Step-by-step explanation:
Set up a proportion: [tex]\frac{24}{30} = \frac{x}{100}[/tex] Cross multiply, then divide: 100 × 24 = 2400, 2400 ÷ 30 = 80So, x equals 80.80/100 = 80%I hope this helps!
The percentage of the month of June that experiences rain is 80%.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Number of days in June = 30.
Number of days in June that rains = 24
Now,
The percentage of days that rain in June.
= 24/30 x 100
= 80%.
Thus,
80% of the days in June rain.

what is the equation of the line that passes through the point (-2,-2) and is parallel to the line 3x-y=2
Answer:
y = 3x + 4
Step-by-step explanation:
Turn the equation from standard form to slope intercept form. So, solve for y.
3x - y = 2
~Subtract 3x to both sides
-y = 2 - 3x
~Divide -1 to everything
y = -2 + 3x
~Reorder
y = 3x - 2
The slope of a parallel line is the same as the original.
Find the new y-intercept.
y = 3x - 2
-2 = 3(-2) + b
-2 = -6 + b
4 = b
y = 3x + 4
Best of Luck!
Solve: – 8( 2x + 4) = 80
Answer:
x=3
Step-by-step explanation:
Simplifying
8(2x + 4) = 80
Reorder the terms:
8(4 + 2x) = 80
(4 * 8 + 2x * 8) = 80
(32 + 16x) = 80
Solving
32 + 16x = 80
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-32' to each side of the equation.
32 + -32 + 16x = 80 + -32
Combine like terms: 32 + -32 = 0
0 + 16x = 80 + -32
16x = 80 + -32
Combine like terms: 80 + -32 = 48
16x = 48
Divide each side by '16'.
x = 3
Simplifying
x = 3
Answer:
x = -7
Step-by-step explanation:
