Answer:
x = - 27
Step-by-step explanation:
Hi !
- 0.45x + 0.15 = 8.1
- (0.45x - 0.15) = 8.1
- (0.30x) = 8.1
- 0.3x = 8.1
x = 8.1 : (- 0.3)
x = 81/10 : (-3/10)
x = 81/10 × (-10/3)
x = - 81/3
x = - 27
Good luck !

Alicia Alley won the Summer Bowling Championship. Her share of the $22,500 in prize money was $3,650. How much did each of the other 10 bowlers receive if the remaining money was divided evenly among the bowlers?
A. $3,650
B. $18,850
C. $1,885
D. $188.50
Answer:
C. $1,885
Step-by-step explanation:
Subtract 3,650 from 22,500 because that is how much Alicia won: 18850
Divide that by 10 since it will be split evenly among the rest of the bowlers: 1,885
The share of each bowler is $1,885. Therefore, option C is the correct answer.
Given that, Alicia Alley won the Summer Bowling Championship. Her share of the $22,500 in prize money was $3,650.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Now, the remaining money=22,500-3,650
=18,850
Share of 10 bowlers=18850/10
=$1,885
The share of each bowler is $1,885. Therefore, option C is the correct answer.

Answer:
5 + (-11) - (11)
= 5+ (-11) -(11)
= -6 - 11
= -6 + - 11
= -17
Answer: -17
Step-by-step explanation:
Add and subtract ( left to right)

Ella has a mass of 56 kg, and Tyrone has a mass of 68 kg. Ella is standing at the top of a skateboard ramp that is
1.5 meters tall. Which conclusion is best supported by the given information?
If Tyrone stands at the top of the same ramp, his potential energy will be less than Ella's
If Tyrone stands at the top of a 1 m high ramp, his potential energy will be greater than Ella's.
If Tyrone stands at the top of the same ramp, his potential energy will be the same as Ella's.
If Tyrone stands at the top of a 2 m high ramp, his potential energy will be greater than Ella's.
Hey
Step-by-step explanation:
Given that,
Mass of Ella is 56 kg and mass of Tyrone is 68 kg.
Position of Ella is 1.5 m on the ramp.
Potential energy of an object is given by :
P = mgh
It is directly proportional to the position of an object.
If Tyrone stands at the top of ramp at more height than Ella, it will have more potential energy. Hence, the correct option is (d) "If Tyrone stands at the top of a 2 m high ramp, his potential energy will be greater than Ella's."
Answer:
it would be d.

Explain how to find the y-intercept from the table. What is the y-intercept?
Answer:
The y-intercept of a graph is the point where the graph crosses the y-axis
Step-by-step explanation:
You can find the y-intercept by looking at the graph and seeing which point crosses the y axis.
The y-intercept is the value of the function when x is zero
Given data ,
To find the y-intercept from a table, you need to identify the point where the x-coordinate is zero. The y-coordinate of this point represents the value of the dependent variable (usually denoted as "y") when the independent variable (usually denoted as "x") is zero. The y-intercept is the point at which the graph of the function intersects or crosses the y-axis.
To find the y-intercept from a table, look for the row or entry where the x-coordinate is zero. The corresponding y-coordinate in that row or entry represents the y-intercept.
Hence , the y-intercept is the value of the function when x is zero, and it represents the point where the graph of the function intersects the y-axis.

Step-by-step explanation:
The instructor had saved $3,500 and rents an apartment
for $275 monthly. He believes the point (6, 1850) would
be on the equation of the line. Is he correct? Explain how
to check if a point is on a line.
Step-by-step explanation:
The instructor had saved $3,500 and rents an apartment for $275 monthly. The slope-intercept form of the above scenario is :
y=-275x+3500
The instructor belives that the point (6, 1850) would be on the equation of the line. Put y = 1850 and x = 6 in the above equation. So,
1850=-275(6)+3500
1850=1850
LHS=RHS
It means that the point (6,1850) lies on the line. Hence, he was correct.
Answer:
Sample Answer: Write the equation using slope and y-intercept in slope-intercept form, y = –275x + 3500. Then, substitute the x and y values of the point into the equation, 1850 = –275(6) + 3500. Simplify to see if both sides are equivalent. Yes, the instructor is correct because both sides are equivalent.

What are the measurements???
Answer:
angle 4 is 31
angle 5 is 59.
Step-by-step explanation:
M<4 and M<5 add up to a right angle which is 90 degrees . so you put it in a equation form.
2x-5+4x-13=90
rearrange it
2x+4x-5-13=90
6x-18=90
add 18 on both sides
6x=108
divide 6 from both sides
and you get x= 18
Plug in x for angle 4 =2(18)-5 = 31
plug in x for angle 5 = 4(18)-13 = 59
While shopping for school
supplies, Ashton buys two 3-ring binders, three packages of
pencils, and two erasers. If he pays using a $20 bill, how much
change will he receive? Eraser : 0.75 package of pencils : 1.50. 3-ring binder : 2.75
Answer:
$8.5
Step-by-step explanation:
Oki, so you have your info laid out. Find out the payment of each material with how much of each material then add it up and subtract from 20. For an easier way, I'll show you.
Two 3-ring binders, each 3-ring binder costs 2.75 so you'll have 2.75 x 2, which equals up to 5.5
Three packages of pencils, each package costs 1.50, therefore it's 1.50 x 3, which is 4.5
Next, two erasers, each one being .75 cents, .75 x 2 is 1.5
Now, add them all. 5.5 + 4.5 + 1.5 = 11.5
Subtract that from $20, 20 - 11.5 = 8.5
Ashton will get $8.5 back.

Domains are your x values.
Ranges are your y values.
Since they are points and not a linear equation you just need to list the x and y points on the graph.
