Step-by-step explanation: Sorry the explination is long i got it of a website i use for my math tests.
Simplifying
3x + 3 = 6x + -57
Reorder the terms:
3 + 3x = 6x + -57
Reorder the terms:
3 + 3x = -57 + 6x
Solving
3 + 3x = -57 + 6x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6x' to each side of the equation.
3 + 3x + -6x = -57 + 6x + -6x
Combine like terms: 3x + -6x = -3x
3 + -3x = -57 + 6x + -6x
Combine like terms: 6x + -6x = 0
3 + -3x = -57 + 0
3 + -3x = -57
Add '-3' to each side of the equation.
3 + -3 + -3x = -57 + -3
Combine like terms: 3 + -3 = 0
0 + -3x = -57 + -3
-3x = -57 + -3
Combine like terms: -57 + -3 = -60
-3x = -60
Divide each side by '-3'.
x = 20
Simplifying
x = 20
Angles A and B are supplementary. If mA = 67, find mB.
Pleas show work!
Answer:
mB = 113 degrees
Step-by-step explanation:
180 - 67 = 113
Answer:
mB=113
Step-by-step explanation:
mA=67
Triangles are 180 with all angles added together.
To find mB subtract mA with 180.
180 - 67 = 113
mB=113

Step-by-step explanation:
Last
year at a certain high school, there were 60 boys on the honor roll and 130 girls
on the honor roll. This year, the number of boys on the honor roll increased by 5%
and the number of girls on the honor roll increased by 20%. By what percentage did
the total number of students on the honor roll increase? Round your answer to the
nearest tenth (if necessary).
Answer:
15.3%
Step-by-step explanation:
60x.05 = 3 boys
130x.20 = 26 girls
3+26 = 29 students
60+130 = 190 total students
(29/190)*100 = 15.3%
Find the distance between the pair of points.
(19,−8) and (−14,−23)
Answer:
36.25 units
Step-by-step explanation:
Hi there!
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex] where two endpoints are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Plug in the given points (19,−8) and (−14,−23):
[tex]d=\sqrt{(19-(-14))^2+(-8-(-23))^2}\\d=\sqrt{(19+14)^2+(-8+23)^2}\\d=\sqrt{(33)^2+(15)^2}\\d=\sqrt{1089+225}\\d=\sqrt{1314}\\d=36.25[/tex]
Therefore, the distance between the points is approximately 36.25 units.
I hope this helps!
Answer:36.25
Step-by-step explanation:distance between (x1, y1) and (x2,y2) is square root of (x2-x1)^2 + (y2-y1)^2. think of graph the distance between two points is the hypotenuse of a right angle triangle where the height is the difference of y and base is the difference of x
= square root of (19+14)^2 +(-23+8)^2= 36.25
6. How high must a crate be in order to hold 120 cubic meters if it has a base area of 24 square meters?
Answer:
height = 5 m
Step-by-step explanation:
The volume (V) of a cuboid is calculated as
V = Ah ( A is area of base and h the height )
Here V = 120 and A = 24 , then
24h = 120 ( divide both sides by 24 )
h = 5
The height of the crate is 5 m

Solve 5/(r-9)=8/(r+5)
Answer:
r = 32 1/3
Step-by-step explanation:
5/(r-9) = 8/(r+5)
cross multiply:
5 x (r + 5) = 8 x ( r - 9)
5r + 25 = 8r - 72
Add 72 to both sides:
5r + 97 = 8r
Subtract 5r from both sides
97 = 3r
Divide both sides by 3
r = 32 1/3
-Chetan K
Answer:
r = 32 1/3 or 97/3
Step-by-step explanation:
Step 1: Cross-multiply.
[tex]5*(r+5)=8*(r-9)[/tex] [tex]5r + 25 = 8r - 72[/tex]Step 2: Subtract 8r from both sides.
[tex]5r + 25 - 8r = 8r - 72 - 8r[/tex] [tex]-3r +25=-72[/tex]Step 3: Subtract 25 from both sides.
[tex]-3r + 25 - 25 = -72 - 25[/tex] [tex]-3r = -97[/tex]Step 4: Divide both sides by -3.
[tex]\frac{-3r}{-3}=\frac{-97}{-3}[/tex] [tex]r=\frac{97}{3}[/tex] [tex]r = 32\frac{1}{3}[/tex]Therefore, r = 32 1/3 or 97/3.

Sam completed the square for the quadratic equation y=1/2x^2−2x+3 in order to determine the minimum value of the equation, as shown.
Answer:
[tex](2,1)[/tex]
Step-by-step explanation:
You can just use the formula [tex]x=-\frac{b}{2a}[/tex]:
[tex]y=ax^2+bx+c[/tex]
[tex]y=\frac{1}{2}x^2-2x+3[/tex]
[tex]x=-\frac{-2}{2(\frac{1}{2})}=\frac{2}{1}=2[/tex]
[tex]y=\frac{1}{2}(2)^2-2(2)+3=\frac{1}{2}(4)-4+3=2-4+3=-2+3=1[/tex]
Therefore, the minimum value of the equation is [tex](2,1)[/tex]

Answer:
3 ÷ 8
Step-by-step explanation:
1. A fraction has two parts: a numerator and a denominator. The numerator is the dividend (the number that is to be divided by the divisor), and the denominator is the divisor (the number that is divided into the dividend).
2. Given the information above, we know that 3 is the numerator, and 8 is the denominator. This means 3 ÷ 8 = 3/8.

I've done the work but I need to know what my new coordinates will be
Here's the question
Use the mapping (x+3, y-5), for the transformation of triangle ABC with vertices A(-2, -4), B(0, 0), and C(1, -3), find the coordinates of the new triangle A’B’C’ . You must show all your work.
And then here is the answer:
You’re going to go left side three points and down five for every point on the graph (ABC) and once you do that label the ABC marks with an apostrophe like so; A’B’C’ for every time you change places
Answer:
A'(1, -9), B'(3, -5), C'(4, -8)Step-by-step explanation:
Use the given rule and find the coordinates as follows:
(x, y) → (x + 3, y - 5)A(-2, -4) → A'(-2 + 3, -4 - 5) = A'(1, -9)B(0, 0) → B'(0 + 3, 0 - 5) = B'(3, -5)C(1, -3) → C'(1 + 3, -3 - 5) = C'(4, - 8)The points are plotted, see the attached.
Answer:
Before I start, wouldn't you go right three times since it's x + 3 not x - 3. Id.k maybe I'm just slow.
Anyways, take your current points which are A(-2,-4), B(0,0), and C(1,-3) and apply the new mapping rule to them. For example: (-2 + 3, -4 -5), and that will give you A' (1,-9). If you do the same to the other two, you'd have B' (3,-5) and C' (4,-8).
I graphed A, B, C, and A', B', C' above for you.⤴⤴
Hope the graph makes sense, good luck :)

when 7 is added to 3 times a number, the sum is multiplied by 2 and 15 is subtracted what is the final answer
Answer:
2(3x+7) -15
Step-by-step explanation:
Let x = unknown number
7 is added to 3 times a number
3x+7
Multiply the sum by 2
2(3x+7)
Subtract 15
2(3x+7) -15
Answer:
Let the required number be " x "
Now, 7 is added to 3 times a number : (3x + 7)
Next, the sum is multiplied by 2 : 2(3x + 7)
And then, 15 is substracted from it : 2(3x + 7) - 15
2(3x + 7) - 15 is the final answer.Hiiii!!!! Can you solve this please?
