Answer:

-4

Step-by-step explanation:

y - 2x = -4   original

3x - 2x = -4  plug in the Y value

x = -4   subtract X values

Answer:

x = 35, x = 27

Step-by-step explanation:

(9)

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:

Step-by-step explanation:

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:the first one is 6 and the seconndone is 4.5  

Step-by-step explanation:

x- gose forward 2

Answer:

7 1/2

Step-by-step explanation:

1. First convert 2 1/2 to an improper fraction (5/2)

2. Then KCF (keep change flip)

3. Your equation will now be 5/2 x 3/1

4. Multiply to get 15/2

5. Change this number to a mixed number and get your final answer.... 7 1/2

Yup you were correct!

Theres no repeating x value.

Answer:

C

Step-by-step explanation:

only one without repeating x values that give diff y values

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:

Distance = 4 miles

Displacement = 0

Step-by-step explanation:

Given that :

Speed of honey bee = 4mph

Total travel time = 1 hour

Distance traveled by the honey bee:

Distance traveled = speed * time

Distance traveled = 4mph * 1 hour

Distance traveled = 4 miles

Displacement = 0 miles ; change in distance from initial position.

Since initial position of the honeybee is the beehive and its final position is the beehive. Hence, the change from its initial position is zero

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
