[tex]\frac{a}{3}[/tex] = 2 ( multiply both sides by 3 to clear the fraction )
a = 6
Answer:
a=6
Step-by-step explanation:
a/3=6-4
a/3=2
a=6

Your school's drama club charges $10 per person for admission to a play. The club borrowed $400 to pay for costumes and props. After paying back the loan, the club has a profit of $100. Write an equation. Let x represent the number of people who attended the play.
Answer:
10x + 400 - y = 100
Step-by-step explanation:
Answer:
50 people came to the play
Step-by-step explanation:
Let x be the amount of people that attended the play
10x=400+100
10x=500
divide by 10 on both sides
50 people came to the play
400+100=500
40 people is $400 for the props
10 people makes $100

What is the length of NO?
N= (7,-4)
O=(-7,-4)
Answer:
I believe it would be 14.
Step-by-step explanation:
The distance between 7 and -7 should be 14.
The length of NO is 14 units
What is the length of NO?Distance between two points is the length of the line segment that connects the two points in a plane.
The formula to find the length is given by:
d =√((x2 – x1)² + (y2 – y1)²)
We:
N= (7,-4) : x1 = 7 , y1 = -4
O = (-7,-4): x2 = -7 , y2 = -4
Using the formula with the given values:
d=√((-7 – 7)² + (-4 – (-4))²)
d=√((-14 )² + (0)²)
d=√196
d= 14
Therefore, the length of NO is 14 units

Connor bought a baseball card eight years ago that has depreciated by $120 since he purchased it. Find the average yearly change in value of the card.
Answer:
The average yearly change in the value of the card is $15/year
Step-by-step explanation:
Here in this question, we are interested in calculating the average yearly change in the value of the card.
From the question, we can see that the value of the baseball card has depreciated by $120, thus we simply want to calculate the average yearly charge in the card value.
Mathematically, that would be ;
the total depreciation value/ number of years
From the question, the total depreciation value is $120 while the number of years is 8
Thus; the average yearly change in value of the card = 120/8 = $15/year

Simplify the expression: y9 * y-2
Answer:
[tex]y^7[/tex]
Step-by-step explanation:
If we want to simplify the expression [tex]y^9 \cdot y^{-2}[/tex], we have to note that exponent rules state that [tex]x^a \cdot x^b = x^{a+b}[/tex].
This means that if we add the exponents, that will be what we raise y to the power of.
[tex]9 + -2 = 9-2 = 7[/tex]
So [tex]y^7[/tex].

Someone help please! I really need to finish this today.
Answer:
m∠E = 43°Step-by-step explanation:
AB║CD ⇒ m∠AGH = m∠CHF = 119° {corresponding angles}
m∠BGE = m∠AGH = 119° {vertical angles}
m∠BGE + m∠B + m∠E = 180° {sum of angles in triangle}
119° + 18° + m∠E = 180°
m∠E = 180° - 137° = 43°

Heather is putting together a square bulletin board for her new room, and the area of the bulletin board is 196 cm2. What is the total distance around the bulletin board?
Answer:
the total distance is 56 cm
Step-by-step explanation:
Given that the area of the bulletin board is 196 cm^2
Based on this, the total distance around the bulletin board is
But before that we need to find out the side
As the area of square is
= side^2
196 = side^2
So side = 14
Now there are four sides, so the total distance is
= 4 × 14
= 56 cm
Hence, the total distance is 56 cm
Answer:
56 cm
Step-by-step explanation:
Determine the measure of the angle labeled (4x+7)°.
Answer:
39°
Step-by-step explanation:
It is the same measure as the one labeled 6x-9, since these are vertical angles.
4x +7 = 6x -9
16 = 2x . . . . . . . . add 9-4x
8 = x
4x+7 = 4(8) +7 = 39
The angle is 39°.

Write the equation of the line, with the given properties, in slope intercept form slope = -2, through(-4,7)
Answer:
y= -2x + 7
Step-by-step explanation:
So in slope intercept y will always equal something so you start with
y= mx + b
m = slope and b = y-intercept
so in this case it would first be
y = -2x + b
and then since we have the point it passes through (-4,7) we know that the line passes through the y axis at 7 hence the y value is 7.
so you finally get
y=-2x+7
The equation of line passes through the point (-4, 7) will be;
⇒ y = - 2x - 1
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The point on the line are (-4, 7).
And, The slope of the line is,
⇒ m = - 2
Now,
Since, The equation of line passes through the point (- 4, 7).
And, Slope of the line is,
m = - 2
Thus, The equation of line with slope - 2 is,
⇒ y - 7 = - 2 (x - (-4))
⇒ y - 7 = - 2 (x + 4)
⇒ y - 7 = - 2x - 8
⇒ y = - 2x - 8 + 7
⇒ y = - 2x - 1
Therefore, The equation of line passes through the point (-4, 7) will be;
⇒ y = - 2x - 1

A bus travels the 100 miles between A and B at 50 mi/h and then another 100 miles between B and C at 70 mi/h. The average speed of the bus for the entire 200-mile trip is:
Answer:
Average speed= 58.3 mi/hourStep-by-step explanation:
The average speed is defined as the total distance traveled divided by the total time taken.
from A to B
distance= 100 miles
speed= 50 mi/h
speed= distance/time
time= distance/speed
time= 100/50
time= 2 hours
from B to C
distance= 100 miles
speed= 70 mi/h
speed= distance/time
time= distance/speed
time= 100/70
time= 10/7 hours
Average speed= total distance/total time
total distance= 200 mile
total time= 2+10/7= (14+10)/7= 24/7
Average speed= 200/24/7
Average speed= 200*7/24
Average speed= 1400/24
Average speed= 58.3 mi/hour
