Mr. Dunbar takes his wife out to dinner at Macados to celebrate the holidays. Their total bill was $48.36 but he had a coupon to save 15% off. He had a great waitress so he planned to leave a 25% tip. How much did Mr. Dunbar spend to take his wife out for dinner?
Answer:
$51.38 or $60.45
Step-by-step explanation:
$48.36 minus 15 percent is $41.10. If you're tipping the waitress 25 percent from that price, then it would be $51.38. If you're tipping the waitress 25 percent from the original price, it would be $60.45.

Use the drop-down menus to explain why 6 is incorrect.
Answer:
7.8
0.2
Step-by-step explanation:
2 is in the ones place, to get to six you need the value of 2 in the tenths place (0.2)
2+5.8 is 7.8 (add the ones places together to get 7)
0.2+5.8=6 (add in the tenths place)

Solve the equation for b 4a + 6c – 2b = 12 .
Answer:
b=2a+3c−6
Step-by-step explanation:
Let's solve for b.
4a+6c−2b=12
Step 1: Add -4a to both sides.
4a−2b+6c+−4a=12+−4a
−2b+6c=−4a+12
Step 2: Add -6c to both sides.
−2b+6c+−6c=−4a+12+−6c
−2b=−4a−6c+12
Step 3: Divide both sides by -2.
−2b
−2
=
−4a−6c+12
−2
b=2a+3c−6
Answer:
b=2a+3c−6
What is the implication, hypothesis and conclusion in this statement all engineers are resourceful.
Answer:
The majority of theorems in mathematics take the form of compound statements. These statements are called conditional and biconditional statements.
The conditional statement from the sentence above is:
If x is an engineer then x is resourceful.
Put in a mathematical form we can refer to the Implication as:
If Xe then R. Or
Xe implies R. Or
Xe if R.
The Hypothesis is stated as
Xe ⇒ R
The statement Xe in an implication Xe ⇒ R is called its hypothesis, premise, or antecedent, and R the conclusion or consequence.
Implications are critical in expressing a logical argument. If an implication is found to be true, then the consequences must be as well when the hypothesis satisfied. This is why is also referred to as a conditional statement.

The area of this rectangle is at most 400 square centimeters. Write and solve an inequality to represent the
possible values for the height, h, for this triangle. Show all steps of your work
Answer:
1ft≤h≤25ft
Step-by-step explanation:
The area of a rectangle is expressed as;
Area = Length * height
A = Lh
If the area of a rectangle is at most 400 square centimeter, this is expressed as;
A ≤400
≤ means at most that is the area of the rectangle cannot be greater than 400
Substitute the given value into the inequality expression
Lh ≤ 400
Given
L = 16
16h ≤ 400
Divide both sides by 16
16h/16 ≤ 400/16
h ≤ 400/16
h ≤ 25
Hence the possible values of the height are with the range 1ft≤h≤25ft since we cannot have a negative value for the dimension
-3x-5=16
what is x in the equation
Answer:
x=−7
Step-by-step explanation:
Step 1: Add 5 to both sides.
−3x−5+5=16+5
−3x=21
Step 2: Divide both sides by -3.
−3x/−3=21/−3
Answer:
x = -7
Step-by-step explanation:
Hello.
I can help.
To solve algebraic equations all you need to do is get rid of everything on the side of the x except the x.
Lets look at your problem.
-3x - 5 = 16
An important thing to note is we are going to get rid of things on the left side of the = by doing the opposite of what they're doing.
If it is addition we do subtraction
If it is division we do multiplication
and so on.
ALSO
Whatever we do on the left side of the = we must do the same thing to the number on the right.
Now, let us start trying to solve this.
You always want to start with the number that is alone without the variable / letter.
So :
-3x - 5 = 16
Since it is -5 lets add 5 to make it 0 and get rid of it.
-3x - 5 = 16
+5 +5
(Remember to do it to the other side of the = too)
Now we have :
-3x = 21
Now we want to get rid of the 3 attached to the x. And since these two are multiplying we need to divide the -3 by itself to make it 1. Since one number divided by itself is 1.
So like this :
-3x = 21
/-3 /-3
NOTE : When you are dividing or multiplying negative numbers there is an important key to be aware of. Here is a short key to go off of :
- x - = +
- x + = -
So a negative times a negative will be a positive.
While a positive times a negative, the negative will over ride the positive and the answer will be negative.
Going back to the equation, here is what we do :
-3x / -3 = +x (Not negative)
And :
21 / -3 = -7 (Is negative)
So now our equation is :
x = -7
And this is our final answer.
I hope this helped.

. When 2 times a number is increased by 4,
the answer is the same as when 25is
decreased by the number. Find the number.
Answer: The number is 7
Step-by-step explanation:
Let x be the [number]
Rephrase the expression
2 times a number is increased by 4, it is the same as 25 decreased by the number
2x+4=25-x
Calculate
Given
2x+4=25-x
Add x on both sides
2x+4+x=25-x+x
3x+4=25
Subtract 4 on both sides
3x+4-4=25-4
3x=21
Divide 3 on both sides
3x/3=21/3
x=7
Hope this helps!! :)

The data above can be modeled by the function f(x) = 0.0425x^2 + 0.07381x - 0.49107 . Using this equation, predict the skid distance for a car that is driving 50 mph.
Answer:
f(50) = 109.44943 feet
Step-by-step explanation:
Modeling
The model of a situation where the skid distance f is measured against the car speed x can be expressed as:
[tex]f(x) = 0.0425x^2 + 0.07381x - 0.49107[/tex]
Using this equation, we can predict the skid distance for a car that is driving at x=50 mph by substituting in the equation of the model:
[tex]f(50) = 0.0425*50^2 + 0.07381*50 - 0.49107[/tex]
[tex]f(50) = 106.25 + 3.6905 - 0.49107[/tex]
f(50) = 109.44943 feet

Answer:
x = 104 degrees
y = 76 degrees
z = 104 degrees
quadrilateral have to add up all of their interior angles to 360 degrees.
x and c are opposite interior angles. after finding that you have to add those 2 together (208) and subtract that from 360. You should get 152. However andgle B (angle y) and angle D are also opposite interiors so you divide 152 by 2 and get 76 degrees.
Also a straight line is 180 degrees so you subtract the degrees of D by 100 to get angle z.
Answer:
m∡x = 104°
m∡y = 76°
m∡z = 104°
Step-by-step explanation:
m∡A ≅ m∡C
m∡B ≅ m∡D
to find m∡B: 2(104) + 2y = 360
208 + 2y = 360
2y = 152
y = 76
m∡z: 180° - 76° = 104°

let two no. be x and y
by question
x+y=5
x=5-y...........(1)
xy=6.............(2)
putting the value of x in equation 2) we get
(5-y)y=6
5y-y²=6
y²-5y+6=0
y²-3y-2y+6=0
y(y-3)-2(y-3)=0
(y-3)(y-2)=0
either
y=3
or
y=2
putting the value of y in equation 1
when y=3
x=5-3=2
when
y=2
x=5-2=3
now
when
x=3 y=2
the sum of the square of the numbers=x²+y²=3²+2²=9+4=13
what is the factored form of -40+2×^2-2x
Answer:
2(x - 5)(x + 4)
Step-by-step explanation:
Given
- 40 + 2x² - 2x , that is
2x² - 2x - 40 ← factor out 2 from each term
= 2(x² - x - 20) ← factorise the quadratic
Consider the factors of the constant term (- 20) which sum to give the coefficient of the x- term (- 1)
The factors are - 5 and + 4 , since
- 5 × 4 = - 20 and - 5 + 4 = - 1 , then
x² - x - 20 = (x - 5)(x + 4) and
2x² - 2x - 40 = 2(x - 5)(x + 4) ← in factored form
