Answer:
27, we know that +3 and +9 are just the same without the signs. And 3 * 9 = 27.
I have to solve for x
The 3 angles of a triangle equal 180.
Subtract the bottom 2 angles from 180 and you get 50
So 8x + 2 = 50
Subtract 2 from both sides:
8x = 48
Divide both sides by 8
X = 6
A test is worth 60 points. Multiple-choice questions are worth 2 points, and
short-answer questions are worth 5 points. If the test has 15 questions, how
many multiple-choice questions are there?
O A. The number of multiple-choice questions minus the number of
short-answer questions is 60.
OB. The number of multiple-choice questions times the number of
short-answer questions is 15.
C. The number of multiple-choice questions plus the number of
short-answer questions is 15.
D. The number of multiple-choice questions plus the number of
short-answer questions is 60
Answer:
C. The number of multiple-choice questions plus the number of
short-answer questions is 15.
Step-by-step explanation:
This question can be solved using a system of equations.
I am going to say that:
x is the number of multiple-choice questions
y is the number of short-answer questions.
Multiple-choice questions are worth 2 points, and short-answer questions are worth 5 points.
This means that:
[tex]2x + 5y = 60[/tex]
The test has 15 questions.
This means that:
[tex]x + y = 15[/tex].
Which means that option C is the correct answer.
Answer:
C. The number of multiple-choice questions plus the number of short-answer questions is 15.
Step-by-step explanation:
x + y = 15
Jason's closet is 4
feet by 5 feet. He has

How much space is

Answer:
10 feet
Step-by-step explanation:
The Function approximate the velocity (in feet per second) of an object dropped from a height of x feet
right before it hits the ground on Earth and on Mars.
Earth: E(X) = 8V
Mars: M(x) = 0.6(E(x))
What is the velocity of an object dropped from a height og 25 feet right before it hits the ground on
Mars?
Answer:
The answer to the question is
It take for the golf ball hit on Mars to reach the ground 8.284 s longer.
Step-by-step explanation:
To Solve the question, we note that the equation of motion is given to us as
h = -1.9·t² + 26·t
Therefore the height
We compare the above equation with the equation of of motion
S = ut - 0.5×g×t² where u = initial velocity = 26 m/s and - 0.5×g = -1.9
Therefore the acceleration due to gravity om mars = -1.9/-0.5 = 3.8 m/s²
We now have the time taken to maximum height given by
v = u - g·t where v = 0 at maximum height
We therefore have u = g·t → 26 = 3.8×t or t = 26/3.8 = 6.84 seconds
The time taken for ball to hit the ground is 2 × the time to reach maximum height = 2 × 6.84 = 13.684 s
The time longer it takes for the ball on Mars to complete the path up to maximum height and down again is 13.684 s - 5.4 s = 8.284 s.

The perimeter of a certain pentagon is 10.5 centimeters. Four sides of this pentagon have the same
length, in centimeters, h, and the other side has a length of 1.7 centimeters, as shown below.
1/3into a percent and a decimal
Answer:
33% or .33
Step-by-step explanation:
Divide 1/3 = .3333 (repeating). I would round to the nearest hundreths place:
1/3 = .33
For the precentage, multiple 0.33 by 100:
100 * 0.33 = 33%
Given: 33 + 6p = 2(p-1) - 3p
Prove: p = -5
Answer:
Let us prove that p=-5
33+ 6p= 2p-2-3p33+6p= -1p-2 33+7p=-2 7p=-35 p=-533 + 6 x -5 = 2(-5 - 1) - 3 x -5

The Gomez’s deck is shown below. The deck is a regular hexagon. It has a perimeter of 45 units. What is the are of the deck
Answer:
The area of the deck is of 146.14 squared units.
Step-by-step explanation:
Regular hexagon:
A regular hexagon has 6 sides, all with the same measure.
Perimeter of a regular hexagon:
The perimeter of a regular hexagon with side x is given by:
[tex]P_h = 6x[/tex]
Area of a regular hexagon:
The area of a regular hexagon with side x is given by:
[tex]A_h = \frac{3\sqrt{3}x^{2}}{2}[/tex]
It has a perimeter of 45 units.
This means that:
[tex]6x = 45[/tex]
[tex]x = \frac{45}{6}[/tex]
[tex]x = 7.5[/tex]
What is the are of the deck
[tex]A_h = \frac{3\sqrt{3}x^{2}}{2} = \frac{3\sqrt{3}*(7.5)^{2}}{2} = 146.14[/tex]
The area of the deck is of 146.14 squared units.
Shawn is placing a fence around a circular garden with 15 foot diameter. How many feet of fencing will Shawn need to buy to enclosed the garden. Use 3.14 for π. Round the answer to the nearest foot
(A) 47 feet
(B) 48 feet
(C) 177 feet
(D) 707 feet
Answer:
47 feet
Step-by-step explanation:
Shawn is placing a fence around a circular garden with diameter of 15 foot
π = 3.14
Therefore the circumference can he calculated as follows
= π × diameter
= 3.14 × 15
= 47.1 feet
Hence the circumference to the beatesr tenth is 47 feet

Make y the subject of the formula
Answer:
[tex] y = \frac{w - x^2}{-2z} [/tex]
Step-by-step explanation:
Given:
w = x² - 2yz
Required:
Solve for y
Solution:
[tex] w = x^2 - 2yz [/tex]
Subtract x^2 from not sides
[tex] w - x^2 = - 2yz [/tex]
Divide not sides by -2z
[tex] \frac{w - x^2}{-2z} = \frac{-2yz}{-2z} [/tex]
[tex] \frac{w - x^2}{-2z} = y [/tex]
[tex] y = \frac{w - x^2}{-2z} [/tex]

The length of a rectangle is 9 yd more than twice the width x. The area is 455 yd?.
Write an equation in terms of x that represents the given relationship.
Answer:
x * (2x + 9) = 455
Step-by-step explanation:
To express the width in terms of x, given information
x = width
The given information says the length is 9 more than 2 times the width. Length can be expressed in terms of x like this.
2x + 9 = length
The area of a rectangle is length x width, and the given area is 455.
x * (2x + 9) = 455 or 2x^2 + 9x = 455
The equation in terms of x of the area of the rectangle should be [tex]2x^2 + 9x = 455[/tex]
Given that
The length of the rectangle is 9 yards i.e. more than twice the width. i.e.. 2x + 9.And, the width is x.The area is 455 yards.The area of the rectangle is
= [tex]length \times breadth[/tex]
[tex](2x + 9( (x) =455 \\\\ 2x^2 + 9x = 455[/tex]
Therefore we can conclude that The equation in terms of x of the area of the rectangle should be [tex]2x^2 + 9x = 455[/tex]

HOW DO YOU GRAPH USING LINER PROBLEMS
Answer:
You need to plot points onto the graph
Step-by-step explanation:
It takes only 2 points to draw a graph of a straight line. In other words, if we can find two points that satisfy the equation of the line, then the line can be accurately drawn. But it can be more than 2 points as well. IT CANNOT BE 1. Just 1 point can fo anything at all. You cannot make a linear line or a line in general with just one point. You need 2 or more to make a line.
