Mira has breakfast at a restaurant. She leaves a 20\%20%20, percent tip of \$1.80$1.80dollar
Answer:
Price of Mira Breakfast = 9 $ before tip
Step-by-step explanation:
Let say Mira's breakfast Price = B $
Tip she left = 20 %
20 % Tip amount = (20/100) B = 0.2B $
Tip Amount She left = $ 1.8
Equating Tip Amount
0.2B = 1.8
=> B = 9
Price of Mira Breakfast = 9 $ before tip

Determine if the equations are parallel, perpendicular, or neither
y = 3x + 5 and y = -1/3x +6
Answer:
Answer: Perpendicular.
Step-by-step explanation:
If you multiply the slopes together you will get -1:
[tex]3 * -\frac{1}{3} = -1[/tex]
Parallel means they have the same slope, so that is easily ruled out here.
12) which of the following is factor of the polynomial x^4+x^3-x^2+x-1
x+1
x-1
Both options 1 and 2
None
Answer:
Answer: None
Step-by-step explanation:
Polynomial Remainder Theorem
The polynomial remainder theorem establishes that the remainder of the division of a polynomial f(x) by (x-k) is equal to f(k), that is, substituting x for k.
We are given the polynomial:
[tex]f(x)= x^4+x^3-x^2+x-1[/tex]
And it's required to know if (x+1) and/or (x-1) are factors of the polynomial.
We apply the theorem for both cases.
For (x+1), we substitute x=-1 into the polynomial:
[tex]f(-1)= (-1)^4+(-1)^3-(-1)^2+(-1)-1[/tex]
[tex]f(-1)= 1-1-1-1-1=-3[/tex]
Since the remainder is not zero, x+1 is not a factor of the given polynomial.
For (x-1), we substitute x=1 into the polynomial:
[tex]f(-1)= (1)^4+(1)^3-(1)^2+(1)-1[/tex]
[tex]f(-1)= 1+1-1+1-1=1[/tex]
Since the remainder is not zero, x-1 is not a factor of the given polynomial.
Answer: None

Freida earns $5.25 per hour and time-and-a-half for overtime for all hours over 40 hours. How much did she earn the week she worked 48 hours?
Answer:
Total earned= $273
Step-by-step explanation:
Giving the following information:
Regular labor hours= $5.25
Overtime labor hours= $5.25*1.5= $7.875
To calculate the total earned, we need to use the following formula:
Regular labor hours= 40*5.25= 210
Overtime labor hours= 8*7.875= 63
Total earned= 210 + 63
Total earned= $273

Solve this algebraic expression:
5x-2(3x)
Answer:
-x
Step-by-step explanation:
Simplifying
5x + 2 = 3x
Reorder the terms:
2 + 5x = 3x
Solving
2 + 5x = 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
2 + 5x + -3x = 3x + -3x
Combine like terms: 5x + -3x = 2x
2 + 2x = 3x + -3x
Combine like terms: 3x + -3x = 0
2 + 2x = 0
Add '-2' to each side of the equation.
2 + -2 + 2x = 0 + -2
Combine like terms: 2 + -2 = 0
0 + 2x = 0 + -2
2x = 0 + -2
Combine like terms: 0 + -2 = -2
2x = -2
Divide each side by '2'.
x = -1
Simplifying
x = -1
= -x

A local hamburger shop sold a combined total of 570 hamburger and cheeseburger on monday. there were 70 more cheeseburger sold than hamburgers. how many hamburgers were sold on Monday?
Answer:
250 hamburgers were sold on monday.
Step-by-step explanation:
were going to subtract 70 from 500 leaving us with 500 and then divide it by 2 (hamburger and cheeseburger). so we have 250 now. then were going to add 70 to 250 and we'd get 320. so there were 320 cheeseburgers sold on monday and 250 hamburgers sold on monday. to check our work, 250+320=570. 570-320=250.
Answer:
215 hamburgers
Step-by-step explanation:
First, you need to find out what 570 divided by 2 is. It's 285 (570/2=285)
Next, you need to add 70 to 285. It's 355 (285+70=355)
Lastly, you need to subtract 355 from 570. It's 215 (570-355=215)
Thus, the were 215 hamburgers sold on Monday.
Hope this is right and helps!

If 2 (3t - 10) + t = 40 + 4t, what is the value of 3t?
The value of 3t is given by the equation A = 75
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
2 ( 3t - 10 ) = 40 + 4t
On simplifying the equation , we get
6t - 60 = 40 + 4t
Subtracting 4t on both sides of the equation , we get
4t - 60 = 40
Adding 60 on both sides of the equation , we get
4t = 100
Divide by 4 on both sides of the equation , we get
t = 25
So , the value of 3t = 25 x 4
The value of 3t = 75
Hence , the equation , 3t = 75

Step-by-step explanation:
Simplify the expression:
[tex]-2x+3-(5-6x)[/tex]
First, we must remove the parentheses. The minus sign before them indicates we must apply the distributive property of multiplication, multiplying all the internal terms by -1:
[tex]-2x+3-5+6x[/tex]
Once the expression is free from parentheses, we collect like terms. There are two pairs of like terms: the terms with x, and the terms with only numbers.
Rearrange the expression:

A photo collage consists of seven equal-sized square photos arranged in a row to form a rectangle. If the total area of the collage is 567 square inches, what is the length of the collage? __ inches
Given:
Seven equal-sized square photos arranged in a row to form a rectangle.
Total area of the collage is 567 square inches.
To find:
The length of the collage.
Solution:
Let the side of each square be x inches.
Seven equal-sized square photos arranged in a row to form a rectangle.
So, length of rectangle is 7x and width is x.
Area of rectangle is
[tex]Area=Length\times width[/tex]
[tex]567=7x\times x[/tex]
[tex]567=7x^2[/tex]
[tex]\dfrac{567}{7}=x^2[/tex]
[tex]81=x^2[/tex]
Taking square root on both sides, we get
[tex]x=\pm \sqrt{81}[/tex]
[tex]x=\pm 9[/tex]
Side cannot be negative. So, x=9 inches.
Now,
Width = 9 inches
Length = 7(9) = 63 inches
Therefore, the length of the rectangle is 63 inches.
