How do you solve this?? It says solve for X.
Answer:
x = 7
Step-by-step explanation:
Ok, so these angle are equal, because they are opposite angle
So we could write as x+16 = 4x - 5
Now we solve the equation:
x+16 = 4x - 5
16+5 = 4x -x
21 = 3x
7 = x

Angles ECD and ACB are congruent, since they form a pair of vertical angles. Let their measure by [tex]y[/tex].
The sum of the interior angles of any triangle is 180°. This means
• in ∆CDE, we have
[tex]x + 100^\circ + y = 180^\circ[/tex]
• in ∆ABC, we have
[tex]4x + 49^\circ + y = 180^\circ[/tex]
Solve for [tex]x[/tex] by eliminating [tex]y[/tex].
[tex](x + 100^\circ + y) - (4x + 49^\circ + y) = 180^\circ - 180^\circ[/tex]
[tex]-3x + 51^\circ = 0[/tex]
[tex]3x = 51^\circ[/tex]

The area of the triangle is 15 square units after using the distance formula.
What is a distance formula?
It is defined as the formula for finding the distance between two points. It has given the shortest path distance between two points.
The distance formula can be given as:
[tex]\rm d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
It is given that:
The triangle is shown on the coordinate plane.
Using the distance formula:
The height of the triangle:
[tex]\rm AC=\sqrt{(-2+2)^2+(-3-3)^2}[/tex]
AC = 6 units
Again using the distance formula:
[tex]\rm BC =\sqrt{(3-(-2))^2+(-3-(-3))^2}[/tex]
BC = 5 units
The area of the triangle = (1/2)6x5
The area of the triangle = 15 square units
Thus, the area of the triangle is 15 square units after using the distance formula.

A sorter at a recycling center separates pieces of glass
into large bins. The table shows the number of pieces
of each color of glass. If each bin can hold 150 pieces of
glass, how many bins will the pieces completely fill? table:
The number of large bins that the pieces will completely fill is 3.
How many bins will the pieces completely fill?Each large bin can contain only one type of colour. In order to determine the number of large bins that would be used for each color, divide the color for each piece.
Number of large bins that would be used for Brown color = 283 / 150 = 1.89.
1 large bins would be completely filled with brown glass color
Number of large bins that would be used for Green color = 116 /1 50 = 0.7
No large bin would be completely filled with the green glass color
Number of large bins that would be used for Clear color = 315 / 150 = 2.1
2 large bins would be completely filled with the clear glass color
The total number of large bins that would be completely filled = 1 + 2 = 3

- The flag of Equatorial Guinea contains an isosceles triangle.
(Recall that an isosceles triangle contains two angles with the
same measure.) If the measure of the third angle of the trian-
gle is 30° more than twice the measure of either of the other
two angles, find the measure of each angle of the triangle.
(Hint: Recall that the sum of the measures of the angles of a
triangle is 180°.)
Please show me step by step how you got the answer, Thanks
The measure of each angle of the triangle is 40°, 40° and 100°.
What is the triangle?
A triangle is a polygon with three vertices and three sides. The angles of the triangle are formed by the connection of the three sides end to end at a point. The triangle's three angles add up to 180 degrees in total.Given:
In an isosceles triangle two of the three angles measure the same.
Let the two angles be equal to x.
The third angle is 20 more than twice the measure of either angle, which means 2x+20.
The angles of a triangle add up to 180 degrees.
(x)+(x)+(2x+20)=180
4x+20=180
4x=160
x=40 degrees
So, the two angles measure 40° each and the third angle would be,
2x+20
=2*40+20
=100°
Therefore, the measure of each angle of the triangle is 40°, 40° and 100°.

The number line shows the distance in meters of two birds, A and B, from a worm located at point X:
A. Using subtraction, the distance between the two birds = |-2.5 - 2.5| = |-5| = 5 meters.
B. Using additive inverses, the distance = 2.5 + 2.5 = 5 meters
How to Find the Distance on a Number Line?The distance between any two points on a number line is the absolute difference of the coordinates of the two points.
What is an Additive Inverse of a Number?The additive inverse of a number is the number that is added to the number to make it zero. For example, the additive inverse of a is -a.
Part A:
Using subtraction, the distance between the two birds = |-2.5 - 2.5| = |-5| = 5 meters.
Part B:
The additive inverse of -2.5 is 2.5.
Using additive inverses, the distance = 2.5 + 2.5

Find the total amount given the original price and tax rate. Round to the nearest cent if necessary
$31.69, 6%
The total amount including the tax rate is found as $34.
What is defined as the percentage?A percentage is a fraction of a whole articulated as just a number between 0 and 100. Nothing is zero percent, everything is 100 percent, half of everything is fifty percent, and nothing is zero percent. To calculate a percentage, divide the fraction of the total by the total and multiply by 100.For the stated conditions in the question.
The original amount = $31.69.
The tax rate is 6%.
The total mount will be the sum of original amount and tax price.
First calculated the tax price;
6% of 31.69 = 6×31.69/100
6% of 31.69 = 1.9014
Tax price = $1.9014.
Total price = original amount + tax price
Total price = $31.69 + 1.9014
Total price = 33.5914
Total price = $34 (Round to the nearest cent.)
Thus, the total amount is estimated as $34.

A cell phone company charges its customers $40 each month for owning a cell phone plan and $0.25 for
each minute the customer talks on the phone. These costs are modeled by the following equation:
C=25m +40, where Crepresents the total cost of the bill and m represents the number of minutes the
customer talked on the phone that month. Given this equation, how many minutes would the customer
have to talk on the phone for their monthly bill to be $84.25? (Hint: plug in 84.25 for the total cost, C, and
solve for the unknown, m).
Answer:
The customer would have 177 minutes to talk on the phone for their monthly bill to be 84.25
Step-by-step explanation:
Point of correction it's not C=25m +40 but it is
C=0.25m +40
Where,
C = $84.25➟ 84.25 = 0.25m + 40
Let's solve your equation step-by-step.
84.25=0.25m+40
Step 1: Flip the equation.
0.25m+40=84.25
Step 2: Subtract 40 from both sides.
0.25m+40−40=84.25−40
0.25m=44.25
Step 3: Divide both sides by 0.25.
0.25m/0.25 = 44.25/0.25
m=177
∴ The customer would have 177 minutes to talk on the phone for their monthly bill to be 84.25

The contrapositive statement is:
If x ≠ 2, then x^2 ≠ 4
And it is false.
How to write the contrapositive statement?
First, we have two propositions:
p = "x^2 = 4"
q = "x = 2"
The contrapositive statement is:
¬q → ¬p
The negation of the propositions are:
¬q = "x ≠ 2"
¬p = "x^2 ≠ 4"
Then the contrapositive statement with the given propositions is:
If x ≠ 2, then x^2 ≠ 4
Now, is this statement true?
No, because we can have:
x = -2 (which is different than 2, so the hypothesis is true)
and x^2 = (-2)^2 = 4
Then the conclusion is false, so the statement is false.
