1/3 + -7/4 as a fraction in simplest form
Answer:
-17/12 = -1 5/12
Step-by-step explanation:
1/3-7/4=
*find a common denominator
*multiply the first fraction times 4 and the second one times 3
4/12- 21/12
-17/14
The addition of the fractions is determined as [tex]\frac{1}{3}+\frac{-7}{4}=\frac{-17}{12}[/tex].
Given data:
To add the fractions 1/3 and -7/4, we need to find a common denominator. The least common multiple of 3 and 4 is 12. So, we will rewrite both fractions with a denominator of 12:
1/3 = (1/3) * (4/4) = 4/12
-7/4 = (-7/4) * (3/3) = -21/12
Now, we can add the fractions:
[tex]\frac{1}{3}+\frac{-7}{4}=\frac{4}{12}+\frac{-21}{12}[/tex]
[tex]= \frac{(4 - 21)}{12 }[/tex]
[tex]=\frac{ -17}{12}[/tex]
The result is [tex]\frac{ -17}{12}[/tex] . This fraction is already in its simplest form, meaning the numerator and denominator do not share any common factors other than 1.
In simpler terms, when we add 1/3 and -7/4, we first find a common denominator of 12. Then, we rewrite the fractions with that denominator and add them.
Hence, the fraction is [tex]\frac{ -17}{12}[/tex].

Last term Mark spent $218 on college textbooks. This term the amount he spent on college textbooks decreased by 26.7%. By how much money did his textbook bill decrease this term? What is his total textbook bill for this term?
Answer:
Money decrease = $58.21
Total Bill = $159.79
Step-by-step explanation:
Starting Value = $218
Percent Decrease = 26.7%
End Value = x
Value Decrease = $218 - x
x = 1(218) - 0.267(21.8)
x = 0.733(218)
x = 159.794 ≈ $159.79
Money Decrease = $218 - $159.79 = $58.21
Total Bill = $159.79
-Chetan K
The amount by which the text book decrease is $58.206
The total textbook bill for the term is $ 159.794
How to calculate the total textbook bill for the term?The first step is the calculate the amount by which the textbook decreased
The formular can be written as
Decrease= original amount × percentage decrease
= 218 × 26.7/100
= 218 × 0.267
= 58.206

The price of a video game is marked up by 35%. What is the new price of the game before the markup was 40$? (help <3)
Answer:
Solution :
Selling price (S.P) = (100 + m)% ⋅ C.P
Here,
M = 35, C.P =40$
Then,
S.P = (100 + 35)% ⋅ 40
S.P = 135% ⋅ 40
S.P = 1.35 ⋅ 40
S.P = 54
So, the selling price is $54.

9x-3x +17= 3x-3x -5
6x+ 17+ 5= -5+5
6x/6= -22/6
x= -3.6
3x-5= 6y+1 ( vertical angles)
3(-3.6) -5 = 6y+ 1
-10.8 -5 -1= 6y +1 -1
-16.8 = 6y

Answer:
In particular, for an expression to be a polynomial term, it must contain no square roots of variables, no fractional or negative powers on the variables, and no variables in the denominators of any fractions.
So I'd say a polynomial is a finite sum of terms in which all variables have whole number exponents and no variable appears in a denominator. The leading term in a polynomial is the term of highest degree. The constant term in a polynomial is the term without a variable.

Answer:
14.4
Step-by-step explanation:
Because the figures are similar, they are basically the same figure. One is just dilated by a certain amount. To figure out the missing x, we need to find out exactly how much the small one is dilated from the bigger one.
Here's how we do that:
We know 9 and 5 are correlating sides because of where they are in relation to the right angle. We can find out how much smaller 5 is than 9 by dividing 9 by 5.
9 ÷ 5 = 1.8
This means that x is going to be bigger than 8 by a multiple of 1.8.
8 × 1.8 = x
14.4 = x

Two cards are randomly drawn. (5 blue cards and 3 yellow cards) What is the probability of drawing two blue cards if the fist card is not included in the second draw? simlify your answer completely
Answer:
5/14
Step-by-step explanation:
The probability of drawing a particular coloured card is the number of cards that are that colour, divided by the total number of cards:
The probability of drawing a blue card on your first draw would be 5 out of (5 + 3) = 5/8
The next draw would be the same principle, but the denominator (bottom number of the fraction) would be 1 less, because you have just taken out 1 card on your first draw:
The probability of drawing a blue card on your second draw (after drawing a blue card first) would be 4 (since you have already taken one) out of (8 - 1) = 4 / 7
To find the probability of both these steps combined, you multiply the two fractions together:
5/8 x 4/7 = 20/56
The question asks you to simplify, which means that the final answer is 5/14

help i need to know what k is
Answer:
k = 5
Step-by-step explanation:
The formula for coefficient of proportionality is y = kx.
In the given problem, the Area of a rectangle corresponds to "y" in the constant of proportionality formula, and "x" is still the same. Since the formula for the area of a rectangle is: A = L × W, then:
A = y
L = k
W = x
y = kx is the same as A = LW or A = L × W
Thus, we're looking for the value for k, which corresponds to the length (L) (which has a constant value).
Below are the calculations for the missing values in the table:
We'll start with x = 0.14, and A = 0.7 since we're given the values for them. We could plug these values into the formula for the Area of a rectangle to find the constant value of the length (L):
A = L * W
0.7 = L * 0.14
Divide both sides by 0.14 to isolate L:
0.7/0.14 = (L * 0.14)/0.14
5 = L ←← Keep in mind, this is the coefficient of proportionality.
x = 3.1:
A = L * W
A = 5 * 3.1
A = 15.5
x = 2.5:
A = 5 * 2.5
A = 12.5
x = 1.2:
A = 5 * 1.2
A = 6
x = 0.9:
A = 5 * 0.9
A = 4.5
Next, we're given the values for the Area, but we're missing the values for x. However, we already have the value for L = 5. We could still follow the same process by plugging in the values into the formula:
A = 0.3:
A = L * W
0.3 = 5 * W
Divide both sides by 5 to solve for W:
[tex]\frac{0.3}{5} = \frac{5 * W}{5}[/tex]
0.06 = W
A = 0.1:
A = L * W
0.1 = 5 * W
Divide both sides by 5 to solve for W:
[tex]\frac{0.1}{5} = \frac{5 * W}{5}[/tex]
0.02 = W
Therefore, k = 5.
if α and β are the zeros of p(x) = x² – 5x + 3, then find the value of α + β – αβ option (a)1, (b)2, (c)3, (d)5 please help
Step-by-step explanation:
if you follow me I will give your answer
Answer:
» (b) 2Step-by-step explanation:
Given equation :p(x) = x²-5x+3: α + β = sum of zeroes = −(coefficient of x) / (coefficient of x²) = -(-5) / 1 = 5/1 = 5
αβ = product of zeroes = (constant term) /(coefficient of x²) = 3/1 = 3So, → α + β – αβ ( α+β = 5 , αβ = 3 ) → 5 – 3 → 2

Step-by-step explanation:
20 ÷ 4 1/2
let's change 4 1/2 into an improper fraction.
20 ÷ 9/2
20 is the same thing as 20/1, so we'll express it that way.
[tex]\frac{20}{1}[/tex] ÷ [tex]\frac{9}{2}[/tex]
in order to divide fractions, you must multiply the first number (20/1) by the inverse of the second number (2/9). I'll put it in normal fraction form for clarity.
20 2
--- × ---
1 9
now we multiply straight across.
40

now we have 40 ÷ 9, which is 4.444...
so your answer is 4.4...
