If you add a negative number you will not have a full answer.

Given:

[tex]\overline{AE}\cong \overline{DE}, \overline{AB}\cong \overline{DC}[/tex]

To prove:

[tex]\Delta ABE\cong \Delta DCE[/tex]

Solution:

In triangle AED,

[tex]\overline{AE}\cong \overline{DE}[/tex]

Two sides of triangle AED are equal, it means triangle AED is an isosceles triangle. The base angles of an isosceles triangle are equal. So,

[tex]\angle A\cong \angle D[/tex]

In triangle ABE and triangle DCE,

[tex]\overline{AE}\cong \overline{DE}[/tex]         (Given)

[tex]\angle A\cong \angle D[/tex]        (Base angles of an isosceles triangle are equal)

[tex]\overline{AB}\cong \overline{DC}[/tex]        (Given)

Two corresponding sides and their included angles are congruent. So, triangles are congruent by SAS postulate of congruence.

[tex]\Delta ABE\cong \Delta DCE[/tex]           (By SAS postulate of congruence)

Hence proved.

Complete question :

Leah is creating satin bows for a wedding. From a 15-meter-long ribbon, she first cuts a piece 3 4/9 meters long. Then she cuts a piece 6 5/9 meters long from the remaining ribbon. How much ribbon does Leah have left?

Answer:

5 m

Step-by-step explanation:

Total ribbon cut :

3 4/9 + 6 5/9 =

31/9 + 59/9

= 90 /9

= 10 meters

Total Length of ribbon = 15 m

Ribbon left :

15 - 10 = 5 m

Answer:

t = 350x + 45,750

Step-by-step explanation:

The linear equation that would represent this scenario perfectly would be the following

t = 350x + 45,750

In this equation, the variable x represents the total number of catering jobs that Melissa and her company are completing. This variable gets multiplied by the cost that she charges for each individual job. Finally, the total amount of money that she has already made so far this year is added to that product to give us the total income that she would make for the year after completing the jobs.

The values will vary by a percentage of 60%.

Finding the difference between two values in a time series, dividing that difference by the initial value, and multiplying by 100 are used to determine the percentage change between the two values.

Given two values 500,000 and 800,000

From the general formula of percentage change

percentage change = (final value - initial value)/ initial value * 100

Percentage change = (800,000 - 500,000)/500,000* 100

Percentage change = 60

Therefore, the percentage change of the given values will be 60%.

Answer:

This is true look at picture for clarification

Answer:

True

Step-by-step explanation:

To see if the points all lie on the line y = 4/3x + 5, substitute their x and y values into the equation, solve, and see if the equation is true.

1) First, substitute the x and y values of (6,13) for the x and y in the equation and solve:

[tex]13 = \frac{4}{3} (6) + 5 \\13 = \frac{24}{3} +\frac{15}{3} \\13 = \frac{39}{3}\\13 = 13[/tex]

The result is a true equation. Thus, (6,13) is on the line.

2) Do the same with the point (21,33):

[tex]33 = \frac{4}{3} (21) + 5 \\33 = \frac{84}{3} +\frac{15}{3} \\33 = \frac{99}{3} \\33 = 33[/tex]

The result is a true equation. Thus, (21,33) is on the line.

3) Finally, do the same with (99, 137):

[tex]137 = \frac{4}{3} (99) + 5\\137 = \frac{396}{3}+\frac{15}{3} \\137 = \frac{411}{3} \\137 = 137[/tex]

The result is a true equation. Thus, (99, 137).

All three points are on the line, thus the statement is true.

Answer:

Step-by-step explanation:

Let d, q, h represent the numbers of dimes, quarters, and halves Brian has. We can write 3 equations in these 3 variables:

  10d +25q +50h = 500 . . . . value of the coins, in cents

  d + q + h = 30 . . . . . . . . . . . total number of coins

  4h = q . . . . . . . . . . . . . . . . . four times as many quarters as halves

Using the last equation to substitute into the other two, we get ...

  10d + 150h = 500

  d +5h = 30

The second equation can be written as ...

  5h = 30 -d

and the first can be written to facilitate substitution:

  10d +30(5h) = 500

  10d +30(30-d) = 500 . . . . . substitute for 5h

  900 -20d = 500 . . . . . . . . . simplify

  400 = 20d . . . . . . . . . . . . . add 20d-500 to both sides

  d = 20 . . . . . . . . . . . . . . . . divide by 20

Brian has 20 dimes.
