Answer:
55%
Step-by-step explanation:
66
120
x 100% = 55%
Answer:
66 is 55% of 120
Step-by-step explanation:
66 = 120 * x%
percent just means out of 100
for example, 20% is equal to 20/100
so, x% is x/100
66 = 120 * x/100
66/[tex]\frac{x}{100}[/tex] = 120
66 * 100/x = 120
6600/x = 120
cross multiply
6600/x = 120/1
6600 * 1 = x * 120
6600/120 = x
x = 55

C. Three
D. Four
Answer:
1
Step-by-step explanation:
Find the value of x in the diagram below.
Answer:
x = 31
Step-by-step explanation:
The 2 sides are congruent, meaning the 2 angles are equal so:
47 = x + 16
subtract 16 from both sides
31 = x

HELP PLEASE ITS Which point would not be a solution to the system of linear inequalities shown below? y -3x+7!
(5,−5)(10,−8)(5,−6)(−10,−7)
Answer:
(-10,-7)
Step-by-step explanation:
Lets start with the equation y>-3x+7
Which of these are solutions?
(5,-5) - yes
(10,-8) - yes
(5,-6) - yes
(-10,-7) - no
Now lets do the equation y<4/5x-2
Which of these are solutions?
(5,-5) - yes
(10,-8) - yes
(5,-6) - yes
(-10,-7) - no
So, the point (-10,-7) is not a solution to the system of equations.
Graph the following system of equation
y= 3x + 11
y= -4x + 4
Answer:
Step-by-step explanation:
Answer:
These equations describe two lines that intersect at the point (-1, 8), one of them with a slope of 3, the other with a slope of -4.
Step-by-step explanation:
We can find the point where these two lines intersect by taking one of the equations, solving it for x, and substituting it into the other equation.
[tex]y = -4x + 4\\-4x = y - 4\\4x = 4 - y\\x = 1 - \frac{y}{4} \\\\y = 3x + 11\\y = 3(1 - \frac{y}{4}) + 11\\y = 3 - \frac{3y}{4} + 11\\y + \frac{3y}{4} = 3 + 11\\\frac{4y}{4} + \frac{3y}{4} = 14\\\frac{7y}{4} = 14\\y = \frac{4}{7} * 14\\y = 4 * \frac{14}{7}\\y = 4 * 2\\y = 8[/tex]
Now we can plug that into our first equation to find x
[tex]x = 1 - \frac{y}[4}\\x = 1 - \frac{8}[4}\\\\x = 1 - 2\\x = -1[/tex]
So these lines intersect at the point (-1, 8), one of them with a slope of 3, the other with a slope of -4

Hello!
[tex]\large\boxed{f^{-1} = \frac{5x+2}{4x-2}, f^{-1}(3) = \frac{17}{10} }[/tex]
[tex]f(x) = \frac{2x +2}{4x - 5}[/tex]
Find the inverse by swapping the x and y variables:
[tex]y = \frac{2x +2}{4x - 5}\\\\x = \frac{2y +2}{4y - 5}[/tex]
Begin simplifying. Multiply both sides by 4y - 5:
[tex]x(4y - 5) = 2y + 2[/tex]
Start isolating for y by subtracting 2 from both sides:
[tex]x(4y - 5) -2 = 2y[/tex]
Distribute x:
[tex]4yx - 5x - 2 = 2y[/tex]
Move the term involving y (4yx) over to the other side:
[tex]- 5x - 2 = 2y - 4yx\\\\[/tex]
Factor out y and divide:
[tex]- 5x - 2 = y(2 - 4x)\\\\y = \frac{-5x-2}{-4x+2} \\\\y = \frac{-(5x + 2)}{-(4x - 2)} \\\\y^{-1} = \frac{5x + 2}{4x - 2}[/tex]
Use this equation to evaluate [tex]f^{-1}(3)[/tex]
[tex]f^{-1}(3) = \frac{5(3) + 2}{4(3) - 2} = \frac{17}{10}[/tex]
Kate's math homework had a set of equations and a one-word problem. She took 3 minutes to solve each equation, then 7 minutes to solve the word problem if it took her 52 minutes total, how many equations did she solve
Answer:
15 equations
Step-by-step explanation:
Let
Number of equations in the homework = x
There is only a one-word problem
y = amount of time used to solve the word problem
She took 3 minutes to solve each equation, then 7 minutes to solve the word problem if it took her 52 minutes total,
Total = 3x + y
52 = 3x + 7
Subtract 7 from both sides
52 - 7 = 3x + 7 - 7
45 = 3x
Divide both sides by 3
x = 45 / 3
= 15
x = 15 equations
Therefore, she solved 15 equations

In the figure below, ray KM is the angle bisector of ZLKJ. If MZLKJ = 82",
what is MZMKJ?
Answer:
41º
Step-by-step explanation:
An angle bisector splits an angle in half. So angle LKM+angle MKJ=angle LKJ. We know angle LKJ=82º, so angle LKM=angle MKJ=82º/2=41º.
