The quotient of the three times a number and the quantity 4 plus the same number. Use n.
if the quotient of three times a number and four is decreased by three, the result is nine. whats the number
Answer :Trevor,
number = x
(3x÷ 4) - 3 = 9
Use a common denominator 4: 3x - 12 = 36
3x = 48
x = 16
Does it fit the original equation?
[(3 x 16) ÷ 4] -3 = (48 ÷ 4) -3 = 12 - 3 = 9
Hope it helps
An isosceles triangle has two sides of equal length. The third side is 7 less than twice the length of one of the other sides. If the perimeter of the triangle is 44 cm, what is the length of the third side?
Answer:
x+x+7-x=44
x+7=44
x=44-7
x=37
The perimeter of a square is defined by the function p(s)=4s if the perimeter is no more than 48 cm, which statement describes the domain for s, the side length of the square?
A. 0 < s ≤ 12
B. [ 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 ]
C. All real numbers
D. s ≤ 12
Answer:
A. 0 < s ≤ 12Step-by-step explanation:
Given
p(s) = 4sIf
P ≤ 48Then
4s ≤ 48s ≤ 12Since perimeter can't be negative or zero, the domain will be:
0 < s ≤ 12Correct choice is A
if L is parallel to M, find the value of each missing variable(s)
Answer:
5. x = 13
6. x = 11; y = 3
Step-by-step explanation:
5. (9x + 2)° = 119° (alternate interior angles are congruent)
[tex] 9x + 2 = 119 [/tex]
Subtract 2 from each side
[tex] 9x + 2 - 2 = 119 - 2 [/tex]
[tex] 9x = 117 [/tex]
Divide both sides by 9
[tex] \frac{9x}{9} = \frac{117}{9} [/tex]
[tex] x = 13 [/tex]
6. (9x + 25)° = (13x - 19)° (corresponding angles are congruent)
[tex] 9x + 25 = 13x - 19 [/tex]
Collect like terms
[tex] 9x - 13x = - 25 - 19 [/tex]
[tex] -4x = -44 [/tex]
Divide both sides by -4
[tex] \frac{-4x}{-4} = \frac{-44}{-4} [/tex]
[tex] x = 11 [/tex]
(13x - 19)° + (17y + 5)° = 180° (linear pair)
[tex] 13x - 19 + 17y + 5 = 180 [/tex]
Plug in the value of x and solve for y
[tex] 13(11) - 19 + 17y + 5 = 180 [/tex]
[tex] 143 - 19 + 17y + 5 = 180 [/tex]
Collect like terms
[tex] 129 + 17y = 180 [/tex]
Subtract 129 from both sides
[tex] 129 + 17y - 129 = 180 - 129 [/tex]
[tex] 17y = 51 [/tex]
Divide both sides by 17
[tex] \frac{17y}{17} = \frac{51}{17} [/tex]
[tex] y = 3 [/tex]
40. A pendulum in a museum swings through
an angle of 60° in 17.3 s. The linear velocity
of the pendulum is 1.32 ft/s. Determine the
length of the pendulum.
Answer:
21.81 ft
Step-by-step explanation:
For an arc of measure α and radius r, the arc length is ...
s = r·α . . . . . . where α is in radians
Then the linear speed is ...
s' = r·α'
Here the rate of change of arc angle is (π/3)/(17.3) rad/s, so the radius can be found to be ...
r = s'/α/ = (1.32 ft/s)/((π/3)/17.3 rad/s) = 1.32·3·17.3/π ft
r ≈ 21.81 ft
The length of the pendulum is about 21.81 feet.

Classify by degree of polynomial:
3x3 - 6x
Answer:
polynomial of degree 3
Step-by-step explanation:
Given
3x³ - 6x
The degree of a polynomial is given by the exponent of the term with the largest exponent.
In this case 3x³ has exponent 3 and - 6x has exponent 1
Thus this is a polynomial of degree 3

q(x)=4/5x-9 q(x)=3 PLEASE HELP
Answer:
x = 15
Step-by-step explanation:
Put the given information in the equation and solve for the variable.
3 = 4/5x - 9
12 = 4/5x . . . . . . . . . . . . . . add 9 to get the x term by itself
(5/4)(12) = (5/4)(4/5)x . . . . multiply by the inverse of the x coefficient

A box contains 7 red, 14 yellow, 21 green, 42 blue, and 84 purple marbles. A marble is drawn at random from the box. Find the odds against drawing a purple or yellow marble.
A. 5 to 7
B. 5 to 12
C. 2 to 7
Answer:
B
Step-by-step explanation:
Here, we are to find the odds against drawing a purple or yellow marble.
Mathematically, the odds against drawing a particular marble color = 1 - the probability of drawing that particular marble color
probability of drawing a purple colored marble = number of purple colored marbles/total number of marbles
= 84/(84 + 42 + 21 + 14 + 7) = 84/168 = 1/2
So the odds against drawing a purple colored marble = 1 - 1/2 = 1/2
The odds against drawing a yellow marble color = 1 - probability of drawing a yellow colored marble
Probability of drawing a yellow colored marble = number of yellow marbles/total number of marbles = 14/168 = 1/12
So the probability of drawing a yellow colored marble or purple colored marble = 1/12 + 1/2 = 7/12
Now, the odds against drawing either of the two = 1 - the probability of drawing either of the 2 = 1 -7/12 = 5/12
or simply put 5 to 12

your cell phone plan cost $24.99 per month plus $0.12 for each text message you send or receive. you have a most $30 to spend on your cell phone bill. what is the maximum number of text messages that you can send or receive next month?
10 points
Answer:
The maximum number of text messages you can send per month would be 41.
Step-by-step explanation:
1. First, you want to create an inequality from the word problem. You know that $24.99 is a constant, so we won't put any variables next to it. You also know that each text message is $0.12, so that would need a variable since it can change each month. You also know that you can spend $30 maximum each month, so that goes on the other side of the inequality. Your inequality will look like this: 0.12x+24.99≤30 (x is the number of text messages).
2. Second, you want to solve for x. To do this, subtract 24.99 from each side. After this, the equation is 0.12x≤5.01
3. Now, divide each side by 0.12. Now your inequality is x≤41.75. This represents how many text messages you can send per month without going over 30.
4. Finally, you have to realize that is impossible to send exactly 41.75 text messages. So, you have to round down to 41 to get an even number of text messages, and that's your answer!
Hope this helps! Feel free to ask any questions :)
Answer:
41 text messages

A weather balloon ascended from an elevation of 18 feet below sea level to an elevation 19 1/2 feet above sea level. What distance dd the weather balloon rise?
Answer:
The ballon rose a distance of 37 1/2 feet
Step-by-step explanation:
Here, we are interested in calculating the level of ascent of the weather balloon.
From the question, we are told that the ballon made a transition from below the sea to above the sea.
Now to calculate the total distance, we shall
be adding the distances below the sea and the distances above;
Mathematically, that would be;
18 feet + 19 1/2 feet = 37 1/2 feet
