Contradicting the last answer, the answer 40 is half of 80, so that answer is actually 50 percent.
And also, a little trick to find out percentages is to multiply the first number in the percentage, with the number you are trying to find
Ex. 20 percent of 70
2 * 7 = 14 percent

Answer:
329/9, the answer seems wrong but I triple checked because I thought so too. The answer is 100% correct
Step-by-step explanation:
Angle EFG + Angle FGH + Angle GEF = 180 degrees
(2x+1) + (6x+2) + (x + 19) = 180 degrees
9x + 22 = 180 degrees
9x = 158 degrees
x= 158/9
x+19 = Angle GEF
158/9 + 19 = Angle GEF
329/9 =Angle GEF
Double check:
(2x+1) + (6x+2) + (x + 19), x=158/9
2(158/9) + 1 = 325/9
6(158/9) +2 = 322/3
(158/9) +19 = 329/9
325/9 + 322/3 + 329/9 = 180
QS is an angle bisector, what is the value of x?
Answers
Answer:
The value of x is 16
Step-by-step explanation:
The angle Bisector of a triangle will divide the opposite side into two segments that are proportional to the other two sides of the triangle
In Δ QPR
∵ QS is the angle bisector
∵ PR is the opposite side
→ By using the rule above
∴ [tex]\frac{PS}{PQ}[/tex] = [tex]\frac{SR}{RQ}[/tex]
∵ PS = x and PQ = 30
∵ PR = 40
∵ RS = PR - PS
∴ RS = 40 - x
∵ RS = 40 - x and RQ = 45
→ Substitute them in the rule above
∴ [tex]\frac{x}{30}[/tex] = [tex]\frac{40-x}{45}[/tex]
→ By using the cross multiplication
∵ x × 45 = 30 × (40 - x)
∴ 45x = 30(40) - 30(x)
∴ 45x = 1200 - 30x
→ Add 30x to both sides
∵ 45x + 30x = 1200 - 30x + 30x
∴ 75x = 1200
→ Divide both sides by 75
∴ x = 16
∴ The value of x is 16

QUESTION:
Simplify each expression
ANSWER:
1.) [tex]\green{{- 8n}}[/tex]
2.) [tex]\green{{- 2b - 60}}[/tex]
3.) [tex]\green{{- 10x - 14}}[/tex]
4.) for number 4 study my step-by-step explanation so you can answer that
STEP-BY-STEP EXPLANATION:
1.) First, If the term doesn't have a coefficients, it is considered that the coefficients is 1
WHY?
Learn why:
Why is it considered that the coefficient is 1?
Remember that any term multiplied by [tex]\blue{{1}}[/tex] remains the same :
[tex]\blue{{1}}[/tex] [tex]{× x = x}[/tex]
Step 1:
The equality can be read in the other way as a well, so any term can be written as a product of [tex]\blue{{1}}[/tex] and itself:
[tex]{x = }[/tex] [tex]\blue{{1}}[/tex] [tex]{× x}[/tex]
Step 2:
Usually, we don't need to write multiplacation sign between the coefficient and variable, so the simple form is:
[tex]{x = 1x}[/tex]
This is why we can write the term without the coefficient as a term with coefficient [tex]{1}[/tex]
Now let's go back to solving as what i said if a term doesn't have a coefficient, it is considered that the coefficient is 1
[tex]{n - 9n}[/tex]
[tex]\red{{1}}[/tex] [tex]{n -9n}[/tex]
Second, Collect like terms by subtracting their coefficients
[tex]\red{{1n - 9n}}[/tex]
[tex]\red{{( 1 - 9)n}}[/tex]
Third, Calculate the difference
how?
Keep the sign of the number with the larger absolute value and subtract the smaller absolute value from larger
[tex]\red{{1 - 9}}[/tex]
[tex]\red{{- (9 - 1)}}[/tex]
Subtract the numbers
- ([tex]\red{{9 - 1}}[/tex])n
- [tex]\red{{8}}[/tex]n
[tex]\green{\boxed{- 8n}}[/tex]
2.) First, Distribute - 6 through the parentheses
how?
Multiply each term in the parentheses by - 6
[tex]\red{{- 6(b + 10)}}[/tex]
[tex]\red{{- 6b - 6 × 10}}[/tex]
Multiply the numbers
- [tex]{6b}[/tex] - [tex]\red{{6 × 10}}[/tex]
- [tex]{6b}[/tex] - [tex]\red{{60}}[/tex]
Second, Collect like term
how?
Collect like terms by calculating the sum or difference of their coefficient
[tex]\red{{- 6b + 4b}}[/tex]
[tex]\red{{(- 6 + 4)b}}[/tex]
Calculate the sum
[tex]\red{{(- 6 + 4)}}[/tex]b
[tex]\red{{-2}}[/tex]b
[tex]\green{\boxed{- 2b - 60}}[/tex]
3.) First, Distribute 2 through parentheses
how?
Multiply each term in the parentheses by 2
[tex]\red{{2(x - 5)}}[/tex]
[tex]\red{{2x - 2 × 5}}[/tex]
Multiply the numbers
[tex]{2x -}[/tex] [tex]\red{{2 × 5}}[/tex]
[tex]{2x -}[/tex] [tex]\red{{10}}[/tex]
Second, Distribute - 4 through the parentheses
how?
Multiply each term in the parentheses by - 4
[tex]\red{{- 4(3x + 1)}}[/tex]
[tex]\red{{- 4 × 3x - 4}}[/tex]
Calculate the product
- [tex]\red{{4 × 3}}[/tex]x - 4
- [tex]\red{{12}}[/tex]x - 4
Third, Collect like terms
how?
Collect like terms by subtracting their coefficient
[tex]\red{{2x - 12x}}[/tex]
[tex]\red{{(2 - 12)x}}[/tex]
Calculate the difference
[tex]\red{{(2 - 12)}}[/tex]x
[tex]\red{{- 10}}[/tex]x
Fourth, Calculate the difference
how?
Factor out the negative sign from the expression
[tex]\red{{- 10 - 4}}[/tex]
[tex]\red{{- (10 + 4)}}[/tex]
Add the numbers
- ([tex]\red{{10 + 4}}[/tex])
- [tex]\red{{14}}[/tex]

Two times x is 16 more than y. The sum of x and two times y is 18.
find the value of y.
Answers
Step-by-step explanation:
We can make 2 equations as follows:
2x = y + 16 and x + 2y = 18
x + 2y = 18 is the same as x = 18 - 2y. Hence, 2(18 - 2y) = 2x = y + 16.
2(18 - 2y) = y + 16
36 - 4y = y + 16
5y = 20
y = 4.

What is f(−1) for the function given? f(x)=x2−3x+8
Answers
Answer:
12
Step-by-step explanation:
I am assuming you are asking for f(x)=x^2-3x+8? You plug (-1) in for all portions of x. This means you get (-1)^2-3(-1)+8. (-1)^2 is simply 1 because -1 x -1=1. 3*-1 is -3. This makes the equation 1 - (-3) + 8. The middle section simplifies down to +3 making it 1+3+8, or 12.

If it costs $12 to enter an amusement park and $0.50 per ride.
how would I explain in words the meaning of f(6) = 15 in context of the problem?
Answers
Answer:
In this problem, the equation is basically as follows:
F(x)=0.5x+12
where f(x) is the total cost and x represents the number of rides
F(6)= 15 means that the total cost of the amusement park when a person rides six rides is $15.

Tire pressure monitoring systems (TPMS) warn the driver when the tire pressure of the vehicle is 28% below the target pressure. Suppose the target tire pressure of a certain car is 32 psi (pounds per square inch)
Answers
Answer:
23.04psiStep-by-step explanation:
Since we are not told what to find, we can as well find the new tire pressure after reducing to 28% of the target pressure
Given the target tire pressure = 32psi
If the tire pressure of the vehicle is 28% below the target pressure, then the pressure of the tire will be;
32 - (28% of the target pressure)
= 32 - (28% of 32)
= 32 - (0.28 * 32)
= 32 - 8.96
= 23.04psi
Hence the new tire pressure if it is 28% below the target is 23.04psi
Y= -2x+4 by graphing
Answers
Answer:
See attached file.
Step-by-step explanation:
This can be graphed by plugging in two distinct x values and solving each for y. That will give you two x,y coordinates to draw on the graph, which will let you trace the line defined by them.
You can get the points where the line intersects the axis by solving either variable for zero. Try giving x a value of 2 or 0 to find those.
Mr. Johnson currently has a square garden. He wants to redesign his garden and make it into a rectangle with a length that is 5 feet shorter than three times its width. He decides the perimeter should be 70. PLEASEEEEE ITS URGENT
Answers
Answer:
Width of the rectangle = 10 feet
Length of the rectangle = 25 feet
Step-by-step explanation:
Perimeter of a rectangle = 2(length + width)
Let
Width of the rectangle = x feet
Length of the rectangle = 3x - 5 feet
Perimeter of the rectangle = 70 feet
Perimeter of a rectangle = 2(length + width)
70 = 2{x + (3x - 5)}
70 = 2{x + 3x - 5}
70 = 2(4x - 5)
70 = 8x - 10
70 + 10 = 8x
80 = 8x
Divide both sides by 8
x = 80 / 8
= 10
Width of the rectangle = 10 feet
Length of the rectangle = 3(10) - 5
= 30 - 5
= 25 feet

In the figure, if m ZABD = 120°, then mZADC =
0.
Answers
Answer:
m∠ADC = 132°
Step-by-step explanation:
From the figure attached,
By applying sine rule in ΔABD,
[tex]\frac{\text{sin}(\angle ABD)}{\text{AD}}=\frac{\text{sin}(\angle ADB)}{AB}[/tex]
[tex]\frac{\text{sin}(120)}{35}=\frac{\text{sin}(\angle ADB)}{30}[/tex]
sin(∠ADB) = [tex]\frac{30\text{sin}(120)}{35}[/tex]
= 0.74231
m∠ADB = [tex]\text{sin}^{-1}(0.74231)[/tex]
= 47.92°
≈ 48°
m∠ADC + m∠ADB = 180° [Linear pair of angles]
m∠ADC + 48° = 180°
m∠ADC = 180° - 48°
m∠ADC = 132°

4x+3/7+2=x+5/2
Answers
Answer:
x= 1/42
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4x+3/7+2=x+5/2
combine like terms (2 and 3/7)
4x+17/7=x+5/2
Step 2: Subtract x from both sides.
4x-x+17/7=x-x+5/2
3x+17/7=5/2
Step 3: Subtract 17/7 from both sides.
3x+17/7−17/7=5/2-17/7
3x=1/14
Step 4: Divide both sides by 3.
3x/3=1/14/3
1/14 * 1/3 = 1/42
x=1/42
