Answer:

x = 14

m∠A = 38°

m∠C = 71°

m∠D = 71°

Step-by-step explanation:

Answer:

AC=AD=71, CD=38

Step-by-step explanation:

AC=AD

5x+1=7x-27

2x=28

x=14

AC=5*14+1=71=AD

CD=3*14-4=38

Answer:

The total sales of Boutique last week = $1300

Step-by-step explanation:

Given that:

Percent of sales came from leggings = 30%

Worth of leggings sold = $390

Let,

x be the total sales in the week.

30% of x = 390

[tex]\frac{30}{100}x=390[/tex]

0.3x = 390

Dividing both sides by 0.3

[tex]\frac{0.3x}{0.3}=\frac{390}{0.3}\\x=1300[/tex]

Hence,

The total sales of Boutique last week = $1300

Original price of the iPhone = $1200.00

Percentage of discount given for memorial day = 35%

Cost of the iPhone after the discount :

[tex]= 1200 - 35\% \: \: of \: \: 1200[/tex]

[tex] = 1200 - \frac{35}{100} \times 1200[/tex]

[tex] = 1200 - \frac{42000}{100} [/tex]

[tex] = 1200 - 420[/tex]

[tex] =\color{hotpink} \$ \: 680[/tex]

Thus, the price of the iPhone after the discount = $680

Percentage of sales tax applied on the discounted price = 8%

Sales tax :

[tex]= 8\% \: \: of \: \: 1200[/tex]

[tex] = \frac{8}{100} \times 1200[/tex]

[tex] = \frac{9600}{100} [/tex]

[tex] = \color{hotpink}\$ \: 96[/tex]

Sales tax = $96

Price of iPhone after sales tax :

[tex] = 680 - 96[/tex]

[tex] =\bold\color{hotpink} \$ \: 584[/tex]

Therefore, the final price of the phone = $584

Answer: $12

Step-by-step explanation: Since all the tickets cost the same amount, then 180 which is the dividend means the total amount of money needed by the sixth grade science club

15 is the divisor and it represents the total number of tickets needed

The quotient is $12

So the cost of one ticket is $12.

Answer:

Option B: x = 15 is a solution, but x = 9 is not is the correct answer.

Step-by-step explanation:

Given equation is:

x - 3 = 12

The solutions we have to check are;

x = 9 and x = 15

Putting x = 9 in the given equation;

9 - 3 = 12

6 ≠ 12

Putting x = 15 in the given equation;

15 - 3 = 12

12 = 12

Hence,

Option B: x = 15 is a solution, but x = 9 is not is the correct answer.

Answer:

The Triangles are congruent by Angle-Side-Angle.

x would equal 4 because the triangles are congruent.

Step-by-step explanation:

Answer:

angle CBE=15 degrees

Step-by-step explanation:

angle ECD is 60 degrees and EC=CD because equilateral triangle

angle DCB is 90 degrees and CB=CD because square

angle ECD +angle DCB= angle ECB

60+90=150=angle ECB

since triangle ECB has legs EC and CB  equal in length, then it is an isosceles triangle.

so angles CBB and CBE are equal

angle CBE=(180-150)/2

angle CBE=15 degrees

Answer:

15 degrees

Step-by-step explanation:

Since triangle CDE is a equilateral triangle then all the sides and angles are congruent DC=CE=ED, ∠DEC=∠ECD=∠CDE=60 degrees

since line CD is also a side of the square and all sides of a square are congruent therefore DC=CB=BA=AD

therefore side BC is equal to side CE which means CBE is an isosceles triangle then angles ∠BEC and ∠CBE are congruent

Then in order to figure out angle ∠CBE we need to find ∠ECB

and ∠ECB=∠DCE+∠DCB

∠DCE= 60 degrees because it's a equilateral triangle

∠DCB=90 degrees because it's a square

therefore ∠ECB=150 degrees

all angles of a triangle = 180 degrees

∠BEC + ∠CBE + ∠ECB = 180

since ∠BEC is congruent to ∠CBE i can substitute ∠BEC for ∠CBE

2(∠CBE) + 150 =180

2(∠CBE)=30

∠CBE=15

Step-by-step explanation:

2x - 3y = 25

+ (5x + 3y = 10)

=> 7x = 35, x = 5.

Therefore 2(5) - 3y = 25, 3y = -15, y = -5.

The solution pair is (5,-5).

Answer:

x = 5

y = -5

so values in boxes = (5, -5)

Answer:

D

Step-by-step explanation:

The change from x = 0 to x = 1 is -3

The change from x = 1 to x = 2 is -5

The average of -3 and -5 is [tex]\frac{-3-5}{2} = \frac{-8}{2} = -4[/tex]

The answer is D. -4

Given GP:

Finding the 5th term:

Correct option is D

Answer:

(0, 3 )

Step-by-step explanation:

Given the 2 equations

x + 3y = 9 → (1)

- 2x + 2y = 6 → (2)

Multiplying (1) by 2 and adding to (2) will eliminate the x- term

2x + 6y = 18 → (3)

Add (2) and (3) term by term to eliminate x, that is

0 + 8y = 24

8y = 24 ( divide both sides by 8 )

y = 3

Substitute y = 3 into either of the 2 equations and solve for x

Substituting into (1)

x + 3(3) = 9

x + 9 = 9 ( subtract 9 from both sides )

x = 0

solution is (0, 3 )

Answer: D) 32

Step-by-step explanation:

The area of a parallelogram equals its base times its height. Substitute the base and area into this formula to solve for the height:

A=bh

40=(5)(h)

h=8

If ABCD is a parallelogram, opposite sides are parallel, so AB is parallel to DC. If AB is parallel to DC, EB is parallel to DC. Since EB is parallel to DC, quadrilateral EBCD has at least one pair of parallel sides, making it a trapezoid. The area of a trapezoid is equal to [tex]\frac{h(b_{1}+b_{2}) }{2}[/tex] where h is the height, [tex]b_{1}[/tex] is one base, and [tex]b_{2}[/tex] is the other base. Plug the necessary values into the formula:

A=[tex]\frac{h(b_{1}+b_{2}) }{2}[/tex]

[tex]b_{1} =AB-AE\\DC=AB\\b_{1} =DC-AE\\b_{1} =5-2\\b_{1} =3[/tex]

[tex]b_{2} =5[/tex]

h=8

A=[tex]\frac{8(3+5)}{2}[/tex]

A=32

The answer is D) 32.
