=============================================================
Explanation:
There are two approaches.
The slightly longer approach will have us take 6% of 420 to get 0.06*420 = 25.20
So 25.20 is the amount of tax you pay on top of the original $420. The total bill is 420+25.20 = 445.20 dollars
--------------
The shortcut is to multiply 420 by 1.06 to get 420*1.06 = 445.20
The 1.06 multiplier indicates an increase of 6%
We can think of it it as 1.06 = 1 + 0.06 = 100% + 6%

In a sale normall prices are reduced by 10% Natalie brought a pair of shoes from the sale and they cost £54 what was the original price
Answer: £60
Step-by-step explanation:
Natalie bought a pair of shoes for £54 which had been reduced by 10%.
To find the original cost, assume the original cost is x.
The discount would be: 10% * x
The expression would therefore be:
x - (10% * x) = 54
x - 0.1x = 54
0.9x = 54
x = 54 / 0.9
x = £60

the coordinates of ABC are A( 2,3), B(6,6) , and C(7,2) . After a translation , the image of vertex A is (-6,1). a). give the coordinates of B and C after the same translation.
Answer:
B (-2, 4)
C (-1, 0)
Step-by-step explanation:
(x,y) -> (x - 8, y - 2)
A (2, 3) -> (2 - 8, 3 - 2) = A (-6, 1)
B (6, 6) -> (6 - 8, 6 - 2) = B (-2, 4)
C (7, 2) -> (7 - 8, 2 - 2) = C (-1, 0)

A multiple-choice test with 50 questions has five possible choices for each question. There are 4 marks for each correct answer, -1 mark for each incorrect answer, and 0 marks for each unanswered question. What is the total score of a student with 35 correct answers, 10 incorrect answers and 5 unanswered questions?
Answer: 130 marks
Step-by-step explanation:
There are 4 marks for every correct answer and there are 4 marks for each correct answer:
= 35 * 4
= 140 correct marks
There are -1 marks for every incorrect answer and there are 10 incorrect answers:
= 10 * -1
= -10 marks
Total score = 140 - 10
= 130 marks
Answer:
130 marks

Triangle A is the pre-image in a translation, and triangle B is the image, as shown below.
On a coordinate plane, triangle A is shifted 6 units to the right to form triangle B.
How was triangle A translated?
four units left
four units right
six units left
six units right
Answer: D is correct
Step-by-step explanation: Got a 100% on my test
The translation of triangle A is (d) six units right
The translation from triangle A to BTranslation involves changing the position of a shape
From the question, we understand that:
Triangle A represents the pre-imageTriangle A is shifted to the right by 6 unitsThis means that, triangle A was translated by 6 units to the right
Hence, the true statement is (d)

7 + x/5 = - 4 x=___ help
Answer:
x = -55
Step-by-step explanation:
7 + x/5 = -4
Combine the constants.
x/5 = -11
Multiply both sides by 5 to simplify the denominator.
x = -55
Check.
7 + (-55)/5 = -4
7 + (-11) = -4
7 - 11 = -4
-4 = -4
Your answer is correct.
Hope this helps!
Answer:
[tex]7 + \frac{x}{5} = - 4 \\ \frac{x}{5} = - 4 - 7 \\ = - 11 \\ x = - 11 \times 5 \\ = - 55[/tex]

The measure of an exterior angle of a triangle is x. The measure of the adjacent interior angle is at least twice x. List three possible solutions for x.
Answer:
x=exterior
y=interior
x+y=180
y is greater than or = to 2x.
So one value could be x+2x=180
3x=180
x=60
or you could do 2x+1+x=180
3x=179
x=179/3
or 2x+2+x=180
3x=178
x=178/3

Answer:
[tex]2 {x}^{3} + 11{x}^{2} - 25x - 28[/tex]
Step-by-step explanation:
Using foil method, Multiply the first term
[tex]2 {x}^{2} \times x = 2 {x}^{3} [/tex]
Next, Multiply the Outer term in each parenthesis. (2x^2 and 7
[tex] 2 {x}^{2} \times 7 = 14 {x}^{2} [/tex]
[tex] 2 {x}^{2} \times 7 = 14 {x}^{2} \: \: \: 3x \times - x = - 3x[/tex]
Then, Multiply the Inner Terms (-3x,-4,7) in each parenthesis
[tex] - 3x \times 7 = - 21x[/tex]
[tex] - 4 \times x = - 4x[/tex]
Then multiply the last term (-4 and 7).
[tex] - 4 \times 7 = - 28[/tex]
Combine it you have
[tex]2 {x}^{3} + 14 {x}^{2} - 3 {x}^{2} - 21x - 4x - 28[/tex]
which simplify to
[tex]2 {x}^{3} + 11 {x}^{2} - 25x - 28[/tex]
X=y-8 and -x-y=0 solve by substitution
Answer:
y=4
Step-by-step explanation:
x=y-8
-x-y=0
-(y-8)-y=0
Distribute the negative
-y+8-y=0
Combine the like terms
-2y+8=0
-8 (to both sides)
-2y=-8
Divide by -2
y=4
