Answer:
65
Step-by-step explanation:
150-(4^2+4)/2
150-(16+4)/2
150-(20)/2
130/2=65
Answer:
140
Step-by-step explanation:
P: parenthesis
E: exponents
M: multiply
D: Division
A: add
S: subtract
150-(4^2+4)/2 exponent first 4^2= 4*4=16 you do this because it is
inside the parenthesis
150-(16+4)/2 you still have parenthesis so solve that next
150-20/2 next you divide because there is no multiplication
150-10 then subtract because there is no addition
140 is your final answer

The measure of the angle x in the right triangle is 67 degrees.
How to find the angle of a right triangle?A right angle triangle has one of its angles as 90 degrees.
The sum of angle in a triangle is 180 degrees.
Therefore,
x + 90 + 23 = 180
x + 113 = 180
x + 113 - 113 = 180 - 113

Suppose that you own a compact car
that you bought new for 18,000 dollars.
The value of this particular make of car is
known to depreciate at a rate of 20%
per year.
Define a unit for each quantity in the
worksheet. Then enter a variable for
the time since you bought the car new
Answer:
Depreciation and Written Down Value for first 5 years of purchase is explained.
Step-by-step explanation:
The Car was purchased for $18000 this will be depreciated at a rate of 20% per year.
Declining Method
Year 1
$18,000 * 20% = $3,600 Depreciation
$18,000 - $3,600 = $14,400 Written Down Value WDV
Year 2
$14,400 * 20% = $2,880 Depreciation
$14,400 - $2,880 = $11,520 WDV
Year 3
$11,520 * 20% = $2,304 Depreciation
$11,520 - $2,304 = $9,216 WDV
Year 4
$9,216 * 20% = $1,843 Depreciation
$9,216 - $1,843 = $7,373 WDV
Year 5
$7,373 * 20% = $1,475 Depreciation
$7,373 - $1,475 = 5,898 WDV

y=5x-9
y=3x+7
Answer:
Step-by-step explanation:
x and y are variables. That means they represent numbers that are unknown. When we solve for x or y, we are trying to find what number the variable represents.
Y is a number that equals both 5x-9 and 3x+7. If it is a number, it can only have one value, so we can say that 5x-9 and 3x+7 have the same value.
In other words, 5x-9 = 3x+7.
Another way of thinking about this step is substitution. y=3x+7, so in the equation y=5x-9, we can replace the y with 3x+7. It will give 3x+7 = 5x-9.
In either case, we have this new equation
5x-9 = 3x+7.
From here it's just simple algebra- subtract 3x from each side
2x -9 = 7
and add 9 to each side
2x = 16
and divide each side by 2.
x = 8.
All these steps work because if two things equal each other, when you do the same thing to both of them (such as add 9), the new values will still equal each other.
Now that we know that x = 8, we can take one of the original equations
y=5x-9
and put 8 in for x.
y=5*(8) -9.
If x represents the value 8, we can obviously switch out x for 8.
Now simplify
y=40 -9
y = 31
Now we know that x = 8 and y = 31.
Answer:
x=8 and y=31
Let's solve your system by substitution.
y=5x−9;y=3x+7
Step: Solve y=5x−9for y:
y=5x−9
Step: Substitute5x−9foryiny=3x+7:
y=3x+7
5x−9=3x+7
5x−9+−3x=3x+7+−3x (Add -3x to both sides)
2x−9=7
2x−9+9=7+9(Add 9 to both sides)
2x=16
2x/2=16/2 (Divide both sides by 2)
x=8
Step: Substitute 8 for x in y=5x−9:
y=5x−9
y=(5)(8)−9
y=31 (Simplify both sides of the equation)
Answer:
x=8 and y=31

I NEED HELP!!! What is is this ----> 3x - 3y = 3 12x + 8y = -8
x = what
y = what
Answer:
3x = 3 + 2y -------------> 3x - 2y = 3 {subtracted 2y from each side of top equation}
(-4/3)x + y = -2/3 ------> -4x + 3y = -2 {multiplied bottom equation by 3}
3x - 2y = 3 ------> 12x - 8y = 12 {multiplied top equation by 4}
-4x + 3y = -2-----> -12x + 9y = -6 {multiplied bottom equation by 3}
12x - 8y = 12
-12x + 9y = -6
--------------
y = 6 {added the two equations}
3x = 3 + 2y {original top equation}
3x = 3 + 2(6) {substituted 6, in for y, into top equation}
3x = 3 + 12 {multiplied}
3x = 15 {added}
x = 5 {divided each side by 3}
x = 5 and y = 6

Angle WXY underwent a sequence of two rotations around different centers. The original size of WXY is 82°. what is the size of the angle after the sequence of rotations?
Given:
[tex]\angle WXY=82^\circ[/tex]
It underwent a sequence of two rotations around different centers.
To find:
The size of the angle WXY after the sequence of rotations.
Solution:
We know that, rotation is a rigid transformation. It means, the size and shape of the figure remains the same after the rotations. It other words, the figure and its image are congruent after rotation.
So, the measure of angle WXY remains same after the sequence of rotations, i.e.,
[tex]\angle W''X''Y''=82^\circ[/tex]
where, [tex]\angle W'X"Y"[/tex] is the image of [tex]\angle WXY[/tex] after the sequence of rotations.
Therefore, the size of the angle WXY after the sequence of rotations is 82°.

Answer:
x = 45
y = 60
Step-by-step explanation:
2x = 90
2x (1/2) = 90 (1/2)
x = 45
3y - 2y = 90
3y - 2(45) = 90
3y - 90 = 90
3y - 90 (+90) = 90 (+90)
3y = 180
3y (1/3) = 180 (1/3)
y = 60

B. Quadrilateral
O C. Trapezoid
O D. Parallelogram
O E. Rectangle
F. Square
Quadrilateral
Trapezoid
The given shape in the image is a Trapezoid. The correct option is C.
What is a trapezoid?A trapezoid is a four-sided polygon with at least one pair of parallel sides. The parallel sides are called the bases of the trapezoid, and the non-parallel sides are called the legs.
The height of a trapezoid is the perpendicular distance between the bases. The area of a trapezoid can be calculated by taking the average of the lengths of the two bases and multiplying by the height.
The perimeter of a trapezoid can be found by adding the lengths of all four sides. Some common types of trapezoids include isosceles trapezoids, where the legs have equal lengths, and right trapezoids, where one of the angles between a leg and a base is a right angle.
Trapezoids are commonly used in geometry and in real-life situations, such as construction, architecture, and engineering.

Express this number in scientific notation. 0.15880.1588
Answer: 1.588×10−1 (The negative one is small on the top right of the 10)
Step-by-step explanation: Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
