Answer: A not a triangle

Step-by-step explanation:

Answer:

14m^2

Step-by-step explanation:

area of triangle = 1/2bh

= 1/2(3)(4) = 6

area of rectangle = bw

=(4)(2) = 8

6+8 = 14

Answer:

14m²

Step-by-step explanation:

rectangle area= 4*2=8

triangle area= 1/2*3*4=6

total area=14

Answer:

Width = 18 inches

Length = 59 inches

Step-by-step explanation:

The length of a rectangle is five more than triple the width. If the perimeter is 154 inches, what are the dimensions

Perimeter of a rectangle = 2L + 2W

The length of a rectangle is five more than triple the width.

L = Length = 5 + 3W

W = Width

If the perimeter is 154 inches, what are the dimensions

Hence,

154 = 2L + 2W

154 = 2(5 + 3W ) + 2W

154 = 10 + 6W + 2W

Collect like terms

154 - 10 = 8W

144 = 8W

W = 144/8

W = 18 inches

Length = 5 + 3W

Length = 5 + 3(18)

Length = 5 + 54

Length = 59 inches

Answer:

C

Step-by-step explanation:

3x-y=14

4x+y=21

add

7x=35

x=35/7=5

4×5+y=21

y=21-20=1

so (5,1 ) is the solution.

Answer:

$2

Step-by-step explanation:

Its actually quite simple.

first find the mean for june.

add $21.50 + $29.75 + $32.00 + $15.25

that is equal to 98.5

then divide by 4.

that is 24.625

do not round to the nearest penny yet.

now you need to find the mean for july.

just add $8 to the total amount you made in june to find the total amount you made in july.

that is 106.5

then divide that by four because you worked four fridays in july as well.

that is 26.625.

finally you need to find the difference between 26.625 and 24.625.

26.625-24.625= 2

and ta-da!!!

the answer us $2.

your welcome. tell me if it is correct.

Answer:

C

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

Ax + By = C ( subtract Ax from both sides )

By = C - Ax ( divide all terms by B )

y = [tex]\frac{C}{B}[/tex] - [tex]\frac{A}{B}[/tex] x , that is

y = - [tex]\frac{A}{B}[/tex] x + [tex]\frac{C}{B}[/tex] → C

Answer:

either 1/9 or -1/9, they both work

Step-by-step explanation:

the problem is |-9x| + 3 = 4

-9x = 1

x = -1/9

Answer:

A. x = 2, y = 12

Step-by-step explanation:

You can solve this problem using similar triangles; you know the triangles are similar because each of the two legs of the triangles are cut in half, meaning the line 5x - 3 is parallel to x + 12. Because of the nature of this figure (the line that is length 5x - 3 cuts the triangle exactly halfway), you can write an equation to find x:

2(5x - 3) = x + 12 (this is a property of triangles when a line is parallel to a base and intersects the triangle at half of that base's height. The line would be half the base)

10x - 6 = x + 12 (simplify)

9x - 6 = 12 (subtract x from both sides)

9x = 18 (add 6 to both sides)

x = 2 (divide both sides by 9)

At this point, you could just click A since that's the only problem where x = 2, but for the sake of properly explaining this problem, I'll continue to find y.

In the image, y + 8 is equal to 2y - 4, shown by the short lines intersecting each side signifying congruence. Now, you can write an equation for this and solve:

y + 8 = 2y - 4

8 = y - 4 (subtract y from both sides)

y - 4 = 8 (switch it around so y is on the left; you don't have to do this, but I think it makes the problem more comfortable to solve)

y = 12 (add 4 to both sides)

Answer:

personally, I would say try using the formula you were taught because there are different ways people do things

Step-by-step explanation:

formula is key

The two angles are vertical angles so they are congruent.

3x+18=5x

2x=18

x=9

Answer:

(3,2)

Step-by-step explanation:

y = -2x + 8

y = x-1

Substitute x-1 for y in the equation y = -2x + 8.  x-1 = -2x + 8

Use the Additive Property to move the

constant terms to one side of the equation.      x-1 = -2x + 8

                                                                                +1           +1

                                                                                  x = -2x + 9

Now do the same to the variable terms.              +2x +2x

                                                                                 3x = 9

Divide both sides of the equation by the

constant in the variable term.                               ÷3 = ÷3

                                                                                   x = 3

To find y, simply substitute the value of x into

one of the original equations.                                 y = x-1

                                                                                   y = 3-1

Solve:                                                                         y = 2

The solution is (3, 2).

Answer: 14,575

Step-by-step explanation:

85(2) 0.4x = 6000      Multiply 85 times 2

170 + 0.4x = 6000      Subtract 170 from both sides

         0.4x = 5830       Divide 5830 by 0.4

             x = 14,575

Answer:

7.385 minutes

Step-by-step explanation:

Given that :

Average speed = 65km/hr

The distance covered = 8km

The time taken Given the information above :

Recall:

Speed = distance / time

Time taken = distance / speed

Time taken = 8km / 65km/hr

Time taken = 0.1230769 hr

Time taken = 0.1230769 * 60 = 7.385 minutes

The time taken to cover this distance is 7.3848 minutes

Speed is the change of an object's distance within a specified period of time.

Mathematically, speed can be calculated by using the relation:

From the given information:

From the above formula, we can make the time the subject of the formula:

By cross multiplying

We all know that:

Thus, time(t) = (0.12308 × 60) minutes

Time(t) = 7.3848 minutes
