Answer:
Step-by-step explanation:
Y) [tex]\frac{x+4}{8}[/tex] = 3
*multiply both sides by 8 - cancels out 8 in denominator*
x + 4 = 24
*subtract 4 from both sides*
x = 20
E) [tex]\frac{x-5}{2}[/tex] = 1
*multiply both sides by 2 - cancels out 2 in denominator*
x - 5 = 2
*add 5 on both sides*
x = 7
N) [tex]\frac{x+2}{4}[/tex] = 2
* multiply both sides by 4 - cancels out 4 in denominator*
x + 2 = 8
*subtract 2 from both sides*
x = 6

b = 92 degrees (choice B)
c = 92 degrees (choice D)
d = 92 degrees (choice F)
================================================
Explanation:
Angles a and b are supplementary because they form a straight angle when combined. The two angles add to 180
a+b = 180
88+b = 180 ... plug in a = 88
b = 180-88 ... subtract 88 from both sides
b = 92
------------
Angles b and c are congruent because they are alternate interior angles. Alternate interior angles are congruent when dealing with parallel lines.
Since the diagonal entrance ramps are parallel, this means the corresponding angles c and d are congruent.
Since b = 92, this means c = 92 and d = 92 also.
whats the definition of a flow chart proof?
A flowchart proof is a visual representation of logical steps used to prove a mathematical statement or theorem.
It involves breaking down the proof into a series of connected statements and reasons, organized in a flowchart format.
Each statement is supported by a reason or justification, demonstrating the logical progression of the proof. Flowchart proofs provide a clear and structured way to present mathematical arguments, allowing for easy comprehension and verification of the proof's validity.
They help in identifying key steps, dependencies, and the overall structure of the proof, making it easier to follow and understand the reasoning behind mathematical statements.

There are 15 questions, and John got an 84% on the quiz, how many questions did John get right and how many wrong?
Answer:
John got 13 questions right and 2 questions wrong.
Step-by-step explanation:
15 questions right equals 100%.
100 {divided by} 15 = % for each question right
Each question is worth (100 diveded by 15) 6.7%.
84% {diveded by} 6.7% = 12.5
100% - 84% = 16%
16% {divided by} 6.7% = 2.38
Because 12.5 has a higher dicimle value than 2.38 and when the amount he got right is added to the amount he got wrong it needs to equal 15, 12.5 becomes 13 and 2.38 becomes 2.
Answer:
[tex]\frac{n}{15} =\frac{84}{100}[/tex]
[tex]n = \frac{21}{25}*5[/tex]
[tex]n = \frac{21*15}{25}[/tex]
[tex]n = \frac{315}{25}[/tex]
[tex]n = \frac{63}{5} or 12.6[/tex]
Help me -2 (8 - e) = 2 - e
Answer:
e = 6
Step-by-step explanation:
Step 1: Write equation
-2(8 - e) = 2 - e
Step 2: Solve for e
Distribute -2: -16 + 2e = 2 - eAdd e to both sides: -16 + 3e = 2Add 16 to both sides: 3e = 18Divide both sides by 3: e = 6Step 3: Check
Plug in e to verify it's a solution.
-2(8 - 6) = 2 - 6
-2(2) = -4
-4 = -4
A triangle has a base of 10 inches and a height of 8 inches. What percent of the area of the triangle is within 4 inches of the base?
Answer:
40%
Step-by-step explanation:
Firstly
Area of triangle when base is 10 inches and height is 8 inches
= 1/2*b*h
= 1/2*10*8
=40square inch
Again when base =4 inches
= 1/2*4*8
= 16square inches
percent of the area of the triangle is within 4 inches of the base
= 16/40*100%
= 40%
A triangle has an 8-inch height and a 10-inch base. The percent of the area of the triangle is within 4 inches of the base exists 40%.
What is meant by the area of triangle?Area of triangle = 1/2 (b h), where b is the base and h is the height, is the fundamental formula for calculating a triangle's area.
The type of the triangle and the known dimensions can affect other formulas that are used to calculate the area of a triangle.
Given: A triangle has an 8-inch height and a 10-inch base.
Let the equation be
Area of a triangle = (1/2) bh
substitute the values in the above equation, we get
= (1/2) × 8 × 10
= 40 square inches.
Once more with a 4 inch base
= 1/2 × 4 × 8
= 16 square inches.
Within 4 inches of the base, % of the triangle's surface area
= 16/40 × 100%
= 40%
Therefore, the percent of the area of the triangle is within 4 inches of the base exists 40%.

A calculator screen shows a number in scientific notation as 4.8E9. Write this number in standard form.
Answer:
4.8 x 10^9
Step-by-step explanation:
E9 is 10 raised to the power of 9
Scientific notation requires you to write a number from 1 to 10 then multiply it by 10 raised to a number x.
In this case:
4.8E9 = 4,800,000,000
Number between 1 and 10 = 4.8
Number of zeroes = 8 but because you have to multiply 4.8 times 10 to get 48 the answer is 4.8 x 10^9... so one extra 10... 1+8=9
Hope you understand

Solve for x, Solve for z, and Solve for y
Answer:
x=38 degrees, y=41 degrees, z=97 degrees
Step-by-step explanation:
The Triangle Angle-Sum Theorem states that all interior angles of a triangle will add up to 180 degrees.
Look at the triangle to the right. The missing value of x will complete the theorem, therefore the equation 59+83+x=180 will find x. x=38 when we solve the equation.
The triangle on the left has two missing variables, but since angles z and 83 degrees are supplementary to each other, we can make another equation z+83=180 since supplementary angles add up to 180 degrees. z=97 when we solve the equation.
Since we have z, we can now find the value of y given the Triangle Angle-Sum Theorem. The equation would be 42+97+y=180 so we can solve for y. y=41 when we solve the equation.
Answer:
x=38
z=97
y=41

Answer:
RT = 23
Step-by-step explanation:
We will have a line that essentially goes like this:
R-----S-----T
The distance from R to S is 12 units.
The distance from S to T is 11 units.
We need to find the distance from R to T.
R is the starting point and T is the ending point.
To find the total distance, we can add both line lengths.
12 + 11 = 23 units
