Answer:

m=12

Step-by-step explanation:

it is right

Answer:

m = 12

Step-by-step explanation:

8(m – 5) = 2(3m - 8)

Distribute the 8 to (m-5) and the 2 to the (3m-8)

8m-40=6m-16

Add 40

8m=6m+24

Subtract 6m

2m=24

Divide 2

m=12

Answer:

Each side of the Rhombus is 5 units

Step-by-step explanation:

Since the sides of a rhombus area all equal in length;

Then, the length of a side is enough to get the lengths of the other sides

Mathematically, finding the distance between two points out of what we are given will be enough to get the measure of one of the side of the rhombus

We apply the distance formula appropriately to get the distance between the side of the Rhombus

D = √(x2-x1)^2 + (y2-y1)^2

let us use the points (-1,0) and (4,0)

D = √(4 + 1)^2 + (0-0)^2

D = √25

D = 5

B. (X,y) (3x.3y)

Step-by-step explanation:

For table 1,

x =  20     36    56     80

y =  4        6       8       10

Taking 20/4 = 5

36/6 = 6

56/8 = 7

80/10 = 8

The value of x/y is not same in any of the cases. The constant of proportionality is different. It means x and y for this table is not proportional.

For table 2,

x = 28    42    56    70

y = 20    30    40    50

Taking 28/20 = 1.4

42/30 = 1.4

56/40 = 1.4

70/50 = 1.4

The value of x/y is same in each case. The constant of proportionality is same i.e. 1.4 in each case.

[tex]\dfrac{x}{y}=1.4\\\\\dfrac{y}{x}=\dfrac{1}{1.4}\\\\\dfrac{y}{x}=\dfrac{5}{7}\\\\y=\dfrac{5}{7}\times x[/tex]

So, y is 5/7 times of the x.

Answer:

x = -4

Step-by-step explanation:

x + 4 = -x - 4

adding both side with x

x + x + 4 = x - x - 4

2x + 4 = -4

give both side (-4)

2x + 4 - 4 = -4 - 4

2x = -8

x = -8/2 = -4

Answer:

2.5

Step-by-step explanation:

Given

See attachment for number line

Required

Determine the opposite of the point

Represent the point with x; we have to first, determine point x

From the number line:

[tex]x = -2.5[/tex]

The opposite of number x is -x

[tex]-x = -(-2.5)[/tex]

[tex]-x = 2.5[/tex]

Hence, the opposite of the point is 2.5

Answer:

the answer should be 12

Step-by-step explanation:

Answer:

f your number is x, then the difference between that number and 8 would be x-8. Twice that is 2(x-8)

Three times the sum of the number and 3 would be 3(x+3). So, you get the equation:

2(x-8)=3(x+3)

2x-16=3x+9

x=-25

Answer:

In all, she bought 8, or three more.

Step-by-step explanation:

If 5 chicken wings are for ten dollars, that means each wing is 2 dollars.

If each wing is two dollars then you divide the sixteen dollars by 2 dollars getting 8 wings.

Answer:

Ellie can buy 8 chicken wings

Step-by-step explanation:

From what we know, Ellie was able to by 5 chicken wings for $10, when dividing 10 by 5 we now know that each chicken wing could've cost her $2. So in order to find out how many chicken wings she can buy we can divide 16 by 2 and get 8. Hope this helps! :)

Answer:

[tex] \frac{3}{4} = \frac{12}{x} \\ 3x = (12 \times 4) \\ x = \frac{(12 \times 4)}{3} \\ x = (4 \times 4) \\ x = 16[/tex]

Answer:

x = 16

Step-by-step explanation:

so 3/4 = 12/x

you Can multiply 3/4 by 4 to get

12/16 = 12 / x

you can assume x = 16 since the numerators are the same

Answer:

y = -3/8(x + 2)^2 + 8

Step-by-step explanation:

vertex form is

y = a(x - b)^2 + c     where a is a constant and (b,c) is the vertex.

The maximum is at (-2, 8)  because x 8 = height and x =-2 is equn. of symmetry

So here we have

y = a(x - (-2))^2 + 8

y = a(x + 2)^2 + 8

Now at the point (-6, 2):

2 = a(-6+2)^2 + 8

2 = 16a + 8

16a = -6

1 = -3/8.

So our equation is y = 3/8(x + 2)^2 + 8

Answer: The first one :)

Step-by-step explanation:

Answer:

The cost when the two companies charge the same is $7,703.

Step-by-step explanation:

Let 'x' represent the number of tons.

For x tons the first company will charge:

5297 + 200.50x

For x tons the second company will charge:

6500 + 100.25x

We want to find x so that both companies charge the same, that is:

5297 + 200.50x = 6500 + 100.25x

x = 12 tons

For 12 tons both companies will charge the same.

The cost charged for 12 tones is:

5297 + 200.50*12 = $7,703

Hope this Helps! :)

The solution for the given equation is -15/7.

The given equation is [tex]\frac{2}{5}x-\frac{3}{2} =\frac{5}{2}x+6[/tex].

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The given equation can be solved as follows:

[tex]\frac{2}{5}x-\frac{3}{2} =\frac{5}{2}x+6[/tex]

⇒ [tex]\frac{2}{5}x-\frac{5}{2}x=6-\frac{3}{2}[/tex]

⇒ [tex]\frac{4}{10}x-\frac{25}{10}x=\frac{12}{2} -\frac{3}{2}[/tex]

⇒ (-21/10) x =9/2

⇒ x = 9/2 × (-10/21)

⇒ x = 3/1 × (-5/7)

⇒ x = -15/7

Therefore, the solution for the given equation is -15/7.

Answer:

The longer length is 35ft

Step-by-step explanation:

Given

[tex]Area = 560[/tex]

[tex]Perimeter = 102[/tex]

Required

Determine the longer length

Represent the length with L and width with W

So, we have:

[tex]L * W = 560[/tex] --- Area

[tex]2*(L+W) = 102[/tex] --- Perimeter

Divide both sides by 2 in:

[tex]2*(L+W) = 102[/tex]

[tex]L + W = 51[/tex]

Make L the subject:

[tex]L = 51 - W[/tex]

Substitute 51 - W for L in [tex]L * W = 560[/tex]

[tex](51 - W) * W = 560[/tex]

[tex]51W - W^2 = 560[/tex]

Reorder the equation

[tex]W^2 - 51W + 560 = 0[/tex]

Expand

[tex]W^2 -35W - 16W + 560 = 0[/tex]

[tex]W(W-35)-16(W-35) = 0[/tex]

[tex](W-16)(W-35) = 0[/tex]

Split:

[tex]W - 16 = 0\ \ \ W - 35 = 0[/tex]

[tex]W = 16\ \ \ W = 35[/tex]

This implies that the longer length is 35ft
