Answer:
-2(x)>30
An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.
x<-15
Step-by-step explanation:
-2(x)>30 means to divide -2 on both sides which is -15.
x>-15
Next you switch the inequality because you multiplied by a negative:
x<-15

Six less than 2 times a number is 50. What is the number?
Answer:
a + b = 50 (Two numbers total 50)
b = a - 6 (one number is 6 less than the other)
Since we have a value, we can use the substitution metod:
a + a - 6 = 50
Simplify:
2a - 6 = 50
From here, you should know how to isolate a variable--add 6 then divide by 2 in this case. That'll give you a, and you'll be able to use that to solve for b.
2(a) -6= 50
2a-6= 50
six goes and adds to 50 on the other side
2a = 56
divide both sides by 2
a= 28
final answer 28

Answer:
m∠AYB = 85°
m∠C = 50°
Step-by-step explanation:
By is the angle bisector of ∠ABC,
Therefore, m∠1 = m∠2 = 30°
m∠3 = 35°
m∠AYB + m∠YAB + m∠ABY = 180°
m∠AYB = 180° - [(m∠1 + m∠2) + m∠3]
= 180° - [(30° + 30°) + 35°]
= 180° - 95°
= 85°
m∠A + m∠B + m∠C = 180°
2(30°) + 2(35)° + m∠C = 180°
60° + 70° + m∠C = 180°
m∠C = 180° - 130°
m∠C= 50°

3(x-4)=2(-2x+1) what does x equal
Answer:
x = 2
Step-by-step explanation:
Given
3(x - 4) = 2(- 2x + 1) ← distribute parenthesis on both sides
3x - 12 = - 4x + 2 ( add 4x to both sides )
7x - 12 = 2 ( add 12 to both sides )
7x = 14 ( divide both sides by 7 )
x = 2
Answer: 2=x
Step-by-step explanation:
3(x-4)=2(-2x+1) <- multiply number outside of parentheses by numbers inside parentheses
1)3x-12=-4x+2
2)-3x -3x <- subtract -3x
-12=-7x+2 <- what you should have after
3)-2 -2 <- subtract 2
-14=-7x <- what you should have after
4)/-7 /-7 <- divide by -7
2=x <- what you should have after

What is the equation of the line in slope-intercept form?
Write your answer using integers, proper fractions, and improper fractions in
simplest form
Answer:
The equation of the line in the slope-intercept form will be:
y = -7xStep-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where
m is the slope b is the y-interceptFrom the attached graph, taking two points
(0, 0)(-10, 70)Finding the slope between (0, 0) and (-10, 70)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(0,\:0\right),\:\left(x_2,\:y_2\right)=\left(-10,\:70\right)[/tex]
[tex]m=\frac{70-0}{-10-0}[/tex]
[tex]m=-7[/tex]
Determining the y-intercept:
We know that the value of y-intercept can be determined by setting x = 0, and determining the corresponding value of y.
From the graph, it is clear that:
at x = 0, y = 0
Thus, the y-intercept b = 0
Now, substituting m = -7 and b = 0 in the slope-intercept form
y = mx+b
y = -7x + 0
y = -7x
Therefore, the the equation of the line in slope-intercept form will be:
y = -7xHELPPPPPPPP
Hynes Strength Headquarters charges $40 for a sign-up fee plus $20 per month to join the gym. Orlando has paid $180 for his gym membership so far. What linear equation represents this situation?
40x + 20y = 180
y - 180 = 20(x - 40)
y = 20x + 40
x = 40y + 20
y = 40x + 20
y - 40 = 20(x - 180)
I think that it is y = 20x + 40 but I’m not sure.

Your family is putting in a rectangular pool in the back yard. The pool's perimeter equals 28 feet. The contractor want the length to equal 5 more feet than 3 times the width. What will the width of your garden be?
Answer:
2.25 ft
Step-by-step explanation:
Perimter= 28ft
W= x ft
L= 3x+5
but
P=2L+2W
substitute
28=2*(3x+5)+2x
28=6x+10+2x
collet like terms
28=8x+10
28-10= 8x
18=8x
divide both sides by 8
x= 18/8
x=2.25 ft
Hence the width is 2.25 ft

(3^4)^2=3^8 you multiply the powers
3^-6 * 3^8= 3^(-6+8)=3^2

Indices are expressed as power or exponent which is raised to a number or a variable.
According to the law of indices

10. Find the width of the canyon.
13.
width = ?
22 m
15 m
160 m
I need help asap
Answer:
Therefore, the width of the canyon is 109.09 meters.
Step-by-step explanation:
* 160/22 = k (Scale Factor)
7.2727 = k
* Let x be the width of the canyon
x / 15 = k
x / 15 = 7.2727
x = 7.2727 (15)
x = 109.09 m
The width of the canyon is 109.09m.
The calculation is as follows:Here we assume x be the width of the canyon.
The k(Scale factor) should be
= [tex]160 \div 22[/tex]
k = 7.2727
So,
[tex]x \div 15 = k\\\\ x \div 15 = 7.2727[/tex]
x = 109.09 m

Answer:
a=16
Step-by-step explanation:
I believe this is right if it is wrong please tell me.
Answer:
16km
Step-by-step explanation:
Since its a right angle triangle we can use the pythogorean theorem, which is a^2 + b^2 = c^2
So if we apply it to this situation we get,
12^2 + b^2 = 20^2
144 + b^2 = 400
b^2= 400 - 144
b^2= 256
b= 16
So the answer is 16km
Hope this helped :)
