Answer: Step 3 was Gabi's mistake

The solution of the Gabi's equation is m = 28. the Gabi's mistake was division in step 3.

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

Step 1:  Distribute

0.1(0.5m + 6) = 2

(0.1 * 0.5m) + (0.1 * 6) = 2

0.05m + 0.6 = 2

Step 2:  Subtract 0.6 from both sides

0.05m + 0.6 - 0.6 = 2 - 0.6

0.05m = 1.4

Step 3:  Divide both sides by 0.05

0.05m / 0.05

= 1.4 / 0.05

m = 28

Hence, the solution of the Gabi's equation is m = 28. the Gabi's mistake was division in step 3.

The value of the equation is 6

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be A

The difference of ( 20 - 2 ) and 1/3 rd of that value

The equation is given as A = ( 1/3 ) ( 20 - 2 )

So , the equation can be simplified as

20 - 2 = 18

And ,

A = 18 x ( 1 / 3 )

A = 6

Answer:

A line is a straight path of points that has no beginning or end. A line segment is a portion of a line that has two endpoints. A ray is a portion of a line which has one endpoint and extends forever in one direction.

Step-by-step explanation:

hope this helps

Answer:

A line is a infinite set of points, forming a straight path. It does not have a beginning or an end. A line segment is a part of a line made by two endpoints. A ray is a part of a line with only 1 endpoint, and stretches forever in the other direction. They are all types of geometric symbols I guess.

Step-by-step explanation:

Answer:

When we have a point (x, y) and we have a dilation of scale factor K about the origin, the new coordinates of the point will be:

(k*x, k*y)

In this case we have a dilation about point P, but let's assume that point P is the origin of coordinates.

Then the coordinates of point B will be (8, 12)

Then after the dilation of scale factor of 1/4, the new coordinates will be:

( (1/4)*8,  (1/4)*12) = (8/4, 12/4) = (2, 3)

This means that the dilated point will be 2 units at the right of P, and 3 units above P.

Step-by-step explanation:

Answer:

Given:

A car travels 2 1/3 miles in 3 1/2 minutes.

We need to find the distance travelled in ​25 minutes, in 1 hour.

So, 2 1/3= 7/3 and 3 1/2 = 7/2

Let's convert them into decimals by dividing them completely.

So, we will get 2.33 miles and 3.5 minutes.

So now we have that 2.33 miles are covered in 3.5 minutes.

Now we need to know the distance covered in 1 minute.

So, 2.33/3.5=0.67

So now we have in one minute 0.67 miles are covered.

Now distance covered in 25 minutes will be:

0.67*25 = 16.75 miles

Now distance covered in one hour:

1 hour = 60 minutes.

So, 0.67*60 = 40.2 miles

So we have distance covered in 25 minutes-16.5 miles and in 1 hour- 40.2 miles.

80 cm²

96 cm²

Step-by-step explanation:

all you do is add the sides together and you should get answer: 56

5 + 5 + 5 + 5 + 5 + 5 + 5 + 5=40   (5x8=40)

4 + 4 + 4 + 4=16  (4x4=16)

40 + 16 = 56

she can buy 5 shirts maximum

100-53.84=46.16 that is how much she has left to spend on shirts. 46.16÷8.19=5.63 but you can't have 0.63 shirts so in the end she can buy 5 shirts

See Explanation

Step-by-step explanation:

Your question do not have enough details for it to be answered. I will solve your question on a general terms using the attached image of a trapezoid

Given

[tex]Area = 8580ft^2[/tex]

From the attachment, we have:

[tex]BC = 100ft[/tex]

[tex]AD = 80ft[/tex]

[tex]h = 60ft[/tex] --- height

The perimeter (P) of a trapezoid is:

[tex]P = AB + BC + CD + AD[/tex]

Substitute values for AD, BC

[tex]P = AB + 100 + CD + 80[/tex]

Collect Like Terms

[tex]P = AB + CD + 80+ 100[/tex]

[tex]P = AB + CD + 180[/tex]

Next, is to calculate the lengths of AB and CD or the sum: AB + CD

The area of a trapezoid is:

[tex]Area = \frac{1}{2}(AB + CD) * h[/tex]

Substitute values for Area and h

[tex]8580= \frac{1}{2}(AB + CD) * 60[/tex]

Multiply both sides by 2

[tex]2*8580= \frac{1}{2}(AB + CD) * 60*2[/tex]

[tex]17160= (AB + CD) * 60[/tex]

Divide both sides by 60

[tex]\frac{17160}{60}= \frac{(AB + CD) * 60}{60}[/tex]

[tex]286 = AB + CD[/tex]

[tex]AB + CD=286[/tex]

Substitute 286 for AB + CD in: [tex]P = AB + CD + 180[/tex]

[tex]P = 286 + 180[/tex]

[tex]P = 466[/tex]

The perimeter of the backyard is 466ft.

Answer:

The smaller angle is 12 and the larger angle is 168

Step-by-step explanation:

Let call the measure of the random angle a. There is a angle that is 14 times of that and supplementary to that the random angle. So that is represented by

[tex]14a[/tex]

Supplementary Angles add up to 180 degrees so let set up an equation

[tex]a + 14a = 180[/tex]

which equal after you combine like with like

[tex]15a = 180[/tex]

Divide 15 by both sides and a=12 and the so smaller angle is 12 and the larger angle is 168

Answer:

A = 192 in²

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )

where h is the perpendicular height and b₁, b₂ the parallel bases

Here h = 12, b₁ = AB = 14 and b₂ = DC = 2 + 14 + 2 = 18, then

A = [tex]\frac{1}{2}[/tex] × 12 × (14 + 18) = 6 × 32 = 192 in²

Because the formula of quadratic equations is y = ax² + bx + c where you can see the only equation with the power of two is equation B

Equation B into quadratic equation

5x² + x = y - 4

y = 5x² + x +4

Function 5x² + x = y - 4 is quadratic .

Hence option B is correct .

Given , Linear and Quadratic function.

Standard form of quadratic function : y = ax² + bx +c

a = coefficient of x² .

b = coefficient of x .

c = constant .

Rearranging the function,

5x² + x = y - 4

y = 5x² + x - 4

Comparing the equation with standard form,

a = 5

b = 1

c = -4

Hence option B is correct .
