The student council at Greenwood High School is selling T-shirts for $20 apiece. Their costs are $5 per shirt, plus $45 for supplies. Selling a certain number of shirts will allow the student council to cover their costs. How many shirts do they need to sell to break even? How much in costs will they have incurred at that point?

Answer:

angle A = 47°

angle B= 48°

Step-by-step explanation:

4x+ 4x+ 4+3+85=180°

8x+92=180°

8x= 180-92

8x= 88°

x= 11°

angle A = 4(11)+3= 47°

angle B = 4(11)+4= 48°

From equation ( i ) :

-4x - y = 19

-y = 19 + 4x

-y = - ( -19 - 4x )

y = -4x - 19 ------ Equation ( iii )

Substituting the value of y from equation ( iii ) in equation ( ii ) , we get :

Answer: -27/70

Step-by-step explanation:

x ÷ 12 − 3x − 1 ÷ 8 = 1

Simplify x ÷ 12 − 3x − 1 ÷ 8.

  Rewrite the division as a fraction.

        x /12 − 3x − 1 ÷ 8 = 1

   Rewrite the division as a fraction.

        x/12− 3x − 1/8 = 1

  To write −3x as a fraction with a common denominator, multiply by  12/ 12

        x/12− 3x ⋅ 12/12 − 1/8 = 1

  Simplify terms.

   Combine −3x and  12/12

        x /12−3x ⋅ 12/12 − 1/8  = 1  

  Combine the numerators over the common denominator.

        (x − 3x ⋅ 12/12) − (1/8)  = 1

  Simplify the numerator.

        (x ⋅ −35/12) -(1/1) =  1

  Move −35 to the left of x.

        −(35 ⋅ x/12) -(1 /8) = 1

   Move the negative in front of the fraction.

        -(35x/12) −(1/8) = 1

Move all terms not containing x to the right side of the equation.

  Add 1/8 to both sides of the equation.

        -(35x/12) = 1 + (1/8)

  Write 1 as a fraction with a common denominator.

        -( 35x /12) =  8/8 + 1 /8

    Combine the numerators over the common denominator.

        -( 35x /12) =  8+1/8

  Add 8 and 1.

        -( 35x /12) =  9/8

Multiply both sides of the equation by − 12/35

        -( 12 /35) ⋅ (− 35x /12 ) = − 12/35 ⋅ 9/8

Simplify both sides of the equation.

   Simplify -( 12 /35) ⋅ (− 35x /12 )

   Cancel the common factor of 12.

              −1/35⋅ (−35x) = − 12/35 ⋅ 9/8

    Cancel the common factor of 35.

               −1 ⋅ (−x) = − 12/35 ⋅ 9/8

   Multiply −1 by −1.

                   1 ⋅ x = − 12/35 ⋅ 9/8

      Multiply x by 1.

                   x = − 12/35 ⋅ 9/8

   Simplify − 12 /35  ⋅ 9/8

   Cancel the common factor of 4.

                   x = −3/35 ⋅ 9 /2

   Multiply −3/35 and 9/2 .

                   x= (−3 ⋅ 9)/( 35 ⋅ 2 )

    Simplify the expression.

   Multiply −3 by 9.

                   x = -27/(35 ⋅ 2)

   Multiply 35 by 2.

                   x= -27/70

The result can be shown in multiple forms.

Exact Form:   x= -27/70

Decimal Form:  x  = −0.3857142...

B- a tra asian between the two figures maps <c to <f

C- Air rotation mapping CB to FD and <B to <D

E- A reflection across CB mapping AC to EF, and <A to <E

Step-by-step explanation:

The rigid motion that verifies the triangles are congruent by SAS is reflection.

In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.

here, we have,

we know that,

The angle of reflection simply means the angle that's formed between the normal ray and the reflected ray. It's the line that's perpendicular to the resulting surface at the point of incidence.

According to the law of reflection, the angle of reflection must be equal to the angle of incidence. Therefore, the rigid motion that verifies the triangles are congruent by SAS is reflection.

Hence, The rigid motion that verifies the triangles are congruent by SAS is reflection.

The solution to the system of equations is the ordered pair in option B. (4, 10).

Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.

Population growth of two towns over a period of five years is represented by the system of equations :

y = x + 6

y = 2x + 2

Here y represents the population growth and x represents the number of years.

Solution of the system of equations is the point where the graph of both equations intersect.

Intersecting point is (4, 10).

Algebraically, we can solve this as,

We have y =  x + 6 and y = 2x + 2.

x + 6 = 2x + 2

x - 2x = 2 - 6

x = 4

y = x + 6 = 4 + 6 = 10

So (x, y) = (4, 10)

Hence the solution to the system of equations  y =  x + 6 and y = 2x + 2 is the point (4, 10).

Answer:

1) a≥−2.5

2) n<1.2

3) b≥−0.8

4) false,

5) r≤0.1

6) y≤0.8

Step-by-step explanation:

1) Divide both sides by -3.2.

−3.2a/-3.2 ≤ 8/-3.2

2) Flip the equation

- n+0.8<2

Subtract 0.8 from the sides

n+0.8−0.8<2−0.8

3) Add 4.2 to both sides.

b−4.2+4.2≥−5+4.2

4) inequality cannot be solved

5) Simplify both sides of the inequality.

−r+5.1≥5

Subtract 5.1 from both sides.

−r+5.1−5.1≥5−5.1

−r≥−0.1

Divide both sides by -1.

-r/-1 ≥ -0.1/-1

6) Flip the equation.

−1.8y≥−1.44

Divide both sides by -1.8.

−1.8y/−1.8 ≥ −1.44/−1.8

Answer:

The length of JF = 3

Step-by-step explanation:

We know that the point of intersection of the Medians of a triangle is called the centroid of a triangle.

Thus,

For the given triangle ΔHIJ,

We also know that the centroid is 2/3 of the distance from each vertex to the midpoint of the opposite side.

Also, each Median is split into two parts such that the longer part is 2 times the length of the smaller part.

In our case,

The median JF is split into two parts such that the longer part JK is 2 times the length of the smaller part KF.

In other words,

JF = KF + JK

Given KF = 1

Also, the longer part JK is 2 times the length of the smaller part KF.

i.e.

JK = 2 KF

JK = 2(1)         ∵ KF = 1

JK = 2

Thus, substituting KF = 1 and JK = 2 in JF = KF + JK

JF = KF + JK

JF = 1 + 2

JF = 3

Therefore, the length of JF = 3
