Answer:

C: Glenda has been over charged by $3.40 for her purchase

Step-by-step explanation:

The amount Glenda is to pay can be found by applying arithmetic

operations to the given parameters in the correct order.

Reasons:

The price of each picture frame = $12.95

Number of picture frame purchased = 4

Price of each mat = $5.89

Number of mats purchased = 4

Total purchase price = $12.95 × 4 + $5.89 × 4 = $75.36

Total purchase price + Tax = $75.36 × 0.065 + $75.36 ≈ $80.26

Express Shipping charges for amount of purchase between $50 to $100 is given from the table as; $8.20

Total bill = Total purchase + Tax + Shipping

Therefore;

Total bill = $80.26 + $8.20 = $88.46

Amount the credit card is billed = $91.86

Amount of over charge = $91.86 - $88.46 = $3.40

Therefore, Glenda has been over charged by $3.40 for her purchase

Answer:

x = 35, x = 27

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

141° is an exterior angle, thus

x + 24 + 2x + 12 = 141 , that is

3x + 36 = 141 ( subtract 36 from both sides )

3x = 105 ( divide both sides by 3 )

x = 35

-----------------------------------------------------------

(11)

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180, that is

2x - 9 + 3x + 2x = 180

7x - 9 = 180 ( add 9 to both sides )

7x = 189 ( divide both sides by 7 )

x = 27

Answer:

Unfortunately I can't do the first one, but the second one is easy

Step-by-step explanation:

To find X in the Q) 11:

1. The triangle is an equilateral traingles meaning angles add up to 180°

2. Add the numbers - 2x - 9 + 3x + 2x = 7x -9

3. Add 9 to 180 (your adding because you changed the side of the number) - 189 = 7x

4. Divide 7 by 189

Your answer is x = 27

Answer:the first one is 6 and the seconndone is 4.5  

Step-by-step explanation:

x- gose forward 2

y- gose 2.5

The laws of exponents I will be using are:

[tex](x^y)^z = x^{yz}[/tex], and [tex]x^y \cdot x^z = x^{y+z}[/tex].

For the first part, [tex](15^3)^3 \cdot 15^{-6} = 15^9 \cdot 15^{-6} = 15^3[/tex].

For the second part, [tex]15 \cdot (15^3)^2 \cdot (15^{-5})^2 = 15 \cdot (15^6) \cdot (15^{-10}) = 15^{1+6-10} = 15^{-3} = \frac{1}{15^3}[/tex].

Step one:

given data

initial balance= $10

she earned extra $23.50 doing errands

hence her balance will be

=10+23.5

=$33.5

Step two:

Required is her balance

we are told that she bought shoes for  $27.75

hence her balance will be

=33.5-27.75

=$5.75

Answer:

9/13, The numerator is always on top and the denominator is always on the bottom.

Answer:

m < 5/6

Step-by-step explanation:

-2 > 6m - 7

5 > 6m

5/6 > m

m < 5/6

Step-by-step explanation:

let eqn be y = mx + b.

2x + 9y = 8

9y = -2x + 8

y = -2/9 x + 8/9

since the lines are perpendicular, product of the slope of the two lines = -1.

hence,

m x -2/9 = -1

m = 9/2

sub (0, -3):

-3 = 9/2(0) + b

b = -3

therefore equation is: y = 9/2x - 3

Answer:

The larger is 22, the smaller is 9.

Step-by-step explanation:

We need to make the two equations for this which would be:

x+y=31

x=2y+4

we can put the second equation into the first

(2y+4)+y=31

3y+4=31

subtract 4 from each side

3y=27

divide each side by 3

y=9

put this y into our second equation

x=2(9)+4

x=18+4

x=22

Answer:

y = 6

Step-by-step explanation:

Answer:

so you need to find x

Step-by-step explanation:

the little fraction beside the equation in parenthesis is what you are multiplying by, and 25 is what is equals , so x-7 times 2/3 or 0.67 = 25  we then divide 25 by 0.67 then plus 7 and the answer is 44.31

Step-by-step explanation:

Answer:

∠ C = 44°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180, that is

4x - 16 +6x - 1 + 4x - 13 = 180°

14x - 30 = 180 ( add 30 to both sides )

14x = 210 ( divide both sides by 14 )

x = 15

Thus

∠ C = 4x - 16 = 4(15) - 16 = 60 - 16 = 44°
