Answer:
x=7
Step-by-step explanation:
(x+16)=(4x-5)
Subtract x from both sides
16=3x-5
Add 5 to both sides
21=3x
Divide both sides to get x=7
Both angles are congruent due to the vertical angles theorem which states that if angles are vertical then they are congruent.
Hope this helps!
x and y are inversely proportional (that is, x and y vary inversely). When x=2/3 then y=6. The value of x, when y=0.5, is ___________.
Answer:
x = 8
Step-by-step explanation:
inversely proportional expression: y = k/x where 'k' is the constant of variation
input x and y values to find 'k'
y = k/x
6 = k ÷ 2/3
6 = k · 3/2
cross-multiply: 3k = 12; so, k = 4
now input 4 for k and 0.5 for y to find x:
0.5 = 4/x
0.5x = 4
x = 8

Answer:
I can answer Part B since I can't explain Part A in words.
Step-by-step explanation:
Angle 2 = 109 degrees (since it is a straight angle witch is 180 degrees. What you need to do is subtract the given with 180.)
Angle 3 = 81 degrees (I don't know how to explain this. Sorry.)
Angle 4 = 81 degrees (I also don't know how to explain this.)

tiffany makes money by commission rates. She gets 21% of everything she sells. If tiffany sold $27000 worth of items this month, what is her salary for the month .
Answer:
[tex]Salary = \$5670[/tex]
Step-by-step explanation:
Given
[tex]Items = \$27000[/tex]
[tex]Rate = 21\%[/tex]
Required
Determine her salary
Her salary is calculated as:
[tex]Salary = Rate * Items[/tex]
This gives:
[tex]Salary = 21\% * \$27000[/tex]
Convert % to decimal
[tex]Salary = 0.21 * \$27000[/tex]
[tex]Salary = \$5670[/tex]

Right Triangles
Right triangles have one of its interior angles with a measure of 90°.
In right triangles the Pythagora's Theorem is satisfied.
Being c the longest side (hypotenuse), a and b the shorter sides (the legs), then:
[tex]c^2=a^2+b^2[/tex]
We have modified the image to include some known data. Both triangles are congruent since they share one side, have a right angle, and have the same base length.
This means the value of x can be calculated as the hypotenuse of the triangle 3-6-x:
[tex]x^2=3^2+6^2=9+36=45[/tex]
[tex]x=\sqrt{45}=\sqrt{9*5}[/tex]
[tex]\boxed{x=3\sqrt{5}}[/tex]

Drag and drop the correct terms to classify the triangles based on sides or angles.
The triangles are classified below.
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
An equilateral triangle is a triangle where all three sides are equal.
The right triangle is a triangle where one angle is 90 degrees.
An isosceles triangle is a triangle where two sides are equal.
An obtuse triangle is a triangle where the angle is greater than 90 degrees
An acute triangle is a triangle where the angles are less than 90 degrees.
A scalene triangle is a triangle where all three sides are different.
Now,
Side 5 cm, 5 cm, 5 cm, and 5 cm is an equilateral triangles.
Since all the sides are the same.
Sides of 3 cm, 5 cm, and 5 cm is an isosceles triangle.
Since the two sides are the same.
Sides of 3 cm, 5 cm, and 7 cm is a scalene triangle.
Since all three sides are different.
Angles of 40°, 50°, and 90° is a right triangle.
Angles of 40°, 60°, and 80° is an acute triangle.
Angles of 40°, 40°, and 100° is an abtuse triangle.
Thus,
The triangles are classified above.

A store owner spends 7x + 13 dollars on two orders of boxes of light bulbs, including shipping.
Part A
If she spends 3x + 5 dollars on the first order of light bulbs, which of the following represents how much she spends on the second-order?
10x + 18
4x + 8
21x + 65
10x + 8
Part B
If the store owner spent a total of $90 on both orders, how much does a box of light bulbs cost in dollars? Enter the number in the box.
Answer:
[tex]B = 4x + 8[/tex]
A box = $11
Step-by-step explanation:
Given
[tex]Total = 7x + 13[/tex]
Represent the first order with A and the second with B.
So, we have:
[tex]A = 3x + 5[/tex]
Solving (a): Find B.
To find B, we make use of:
[tex]A + B = Total[/tex]
Make B the subject
[tex]B = Total - A[/tex]
Substitute values for Total and A
[tex]B = 7x + 13 - (3x + 5)[/tex]
Open bracket
[tex]B = 7x + 13 - 3x - 5[/tex]
Collect Like Terms
[tex]B = 7x - 3x + 13 - 5[/tex]
[tex]B = 4x + 8[/tex]
Solving (b): Cost of a box of light bulb
This means that:
[tex]Total = 90[/tex]
Substitute 7x + 13 for Total
[tex]7x + 13 = 90[/tex]
Collect Like Terms
[tex]7x = 90 - 13[/tex]
[tex]7x = 77[/tex]
Make x the subject
[tex]x = \frac{77}{7}[/tex]

At Emmy's Swimwear, there are 28 bikini styles and 42 other types of swimsuit. What percentage of the swimsuit styles are bikinis?
Answer:
Approximately 66.66% of swimsuit styles are bikinis.
Step-by-step explanation:
Given
Bikini styles Swimwear = 28Other types of Swimsuit = 42Let 'x' be the percentage of the swimsuit styles are bikinis.
so
x% of 42 = 28
[tex]\frac{x}{100}\times \:42=28[/tex]
[tex]42x = 100 \times 28[/tex]
[tex]42x = 2800[/tex]
divide both sides by 42
[tex]\frac{42x}{42}=\frac{2800}{42}[/tex]
simplify
[tex]\:\:x\:\approx \:66.66\:\%[/tex]
Therefore, Approximately 66.66% of swimsuit styles are bikinis.
