Answer:
(8, 72)
Step-by-step explanation:
Here we have two separate equations for y: y = 9x and y = 2x + 56.
Equating these equations eliminates y temporarily; we get:
9x = 2x + 56, or 7x = 56. Dividing both sides by 7 results in x = 8.
Then, by the first equation, y = 9(8) = 72.
The solution is (8, 72).

Marshall compared his 8 most recent cell phone bills. They were $102, $97 $98 $102 $98 $104 $95 and 102 what was the mode cost
Answer:
$102
Step-by-step explanation:
The word MODE is a statistical term that refers to the number in a given set of data that occurs the most.
In the above question, we are given the set of data:
$102, $97, $98, $102, $98, $104, $95 and $102
Rearranging, we have:
$95, $97, $98, $98, $102, $102, $102, $104.
The mode cost in the given data set above is the phone cost bill that occurred the most and this is $102.
$102 occurred 3 times in the data set.

area of a parallelogram is just L x W so just divide to get the base.
For what value of k does the equation 6(x + 1) + 2 = 3(k5x + 1) + 3 have no solution?
Answer:
k = (6/15)
Step-by-step explanation:
The equation is:
6*(x + 1) + 2 = 3*(k*5*x + 1) + 3
To have no solutions, we need to have something like:
x + 7 = x + 4
where we can remove x in both sides and end with
7 = 4
So this equation is false, meaning that there is no value of x such that this equation is true, then the equation has no solutions.
First, let's try to simplify our equation:
6*(x + 1) + 2 = 3*(k*5*x + 1) + 3
6*x + 6 + 2 = 3*k*5*x + 3*1 + 3
6*x + 8 = 15*k*x + 6
if 15*k = 6, then the system clerly has no solution.
then:
k = 6/15
then we get:
6*x + 8 = (6/15)*15*x + 6
6*x + 8 = 6*x + 6
8 = 6
The system has no solutions.

What is the DIFFERENCE, in centimeters, between the
Circumference of the Inner circle and the circumference of the
Outer circle? Use 3.1415 for 7.
Answer:
12.566 m or 1,256.6 cm
Step-by-step explanation:
Find the circumference of both circles and subtract the circumference of the smaller circle from the larger circle.
C = 2πr or πd
C (larger) = 2(2+9)π or 22π
C (smaller) = 2(9)π or 18π
Difference = 4π or 4(3.1415) which equals 12.566
For of x for. X+3y=-3

Complete the equation of the line whose slope is -5/3
and y-intercept is (0, -2).
Answer:
these are tough, it takes a lot of practice to get used to these, sooo
Step-by-step explanation:
we know the slope, m= -5/3, and we're given a point so use the point slope formula
y= mx + b
the point we are given is in this form (x,y)
then plug the information into our point slope formula
y = (-5/3) x + (-2)
y = -5x/3 -2

Open the line segment reflection application. Line segment AB is a reflection of line segment CD across the x-axis. Click the reflect over x-axis button. Are line segments AB and CD the same? What does this mean about how a line segment changes when you reflect it?
Answer:
Step-by-step explanation:
Line segment AB is reflected across x-axis to form segment CD.
Since, refection is a rigid transformation,
Length of the segment will be same.
But y-coordinates of the extreme ends of the image segment will change in sign notation.
Since, signs of y-coordinates gets changed, sign notation of the slope (image segment) will also get changed (Slope of AB → negative, slope of CD → positive)
Mike went on a vacation to ohio.When he went home the odemeter read 7,219.4 miles.When he returned home the odemeter read 8,192.6 miles.How many miles did mike travel?
Answer:
973.2 miles
Step-by-step explanation:
miles travelled = miles on the odemeter after the trip - miles on the odemeter before the trip
8192.6 - 7219.4 = 973.2
what equation do you have to do to get the number pi

Marissa is reading over her blood work results from her doctor. According to the report, there are about 3.7 × 105 platelets and about 9,300 white blood cells in a microliter of blood.
What is the total number of platelets and white blood cells in a microliter of blood?
Answer/Step-by-step explanation:
First Multiply the given expresion --> 3.7 * 105
3.7*105 = 388.5
Therefor there is 388.5 platelets.
There is 9300 white blood cell.
Sicne you are finding out the TOTAL of BOTH TOGETHER you add them.
388.5 + 9300 = 9688.5
ANSWER: 9688.5 in total.
Answer:
3.8 × 105
Step-by-step explanation:
Add to find the total number of platelets and white blood cells in a microliter of blood.
First, write the number of white blood cells in scientific notation.
Now that both numbers are written in scientific notation, compare the exponents. Since both exponents are not the same, rewrite 9.3 × 103 as 0.093 × 105. Now the numbers multiplied by the powers of 10 can be added while keeping the power of 10 the same.
So, there are about 3.8 × 105 platelets and white blood cells in a microliter of blood.

A season has96 home games. If you purchase a season ticket in the bleacher section, what is the cost per game,in dollars, for this ticket
Answer:
$8.4375 per game
Step-by-step explanation:
From. The picture attached :
Season long Ticket cost for the bleachers sitting area is : $810
Given that the number of home games in a season is 96
The cost per unit of game could be calculated as :
Cost of season long Ticket / number of home games
= $810 / 96
= $8.4375
$8.4375 per game

I'm trying to understand this!!
Answer:
eric=12
bill=16
Step-by-step explanation:
you can solve this using two simple algebraic equations. this is the key I will be using:
x=bill
y=Eric
x+y=28
x=y+4
since x is by itself in the second equation, I can replace the x in the first equation with y+4
(y+4)+y=28
subtract 4 from both sides
y+y=24
which is also 2y=24
divide both sides by two.
y=12
so now we know Eric is 12 years old.
using this, we can replace the "y" in the second original equation (x=y+4)
x=12+4
x=16
Bill is 16 years old.

Find the surface area of the cylinder with diameter 20 in. and height 2 in. Use 3.14 for
pi.
Answer:
[tex]\boxed {\boxed {\sf SA= 753.6 \ in^2}}[/tex]
Step-by-step explanation:
The surface area of a cylinder is found using this formula.
[tex]SA=2 \pi rh+ 2 \pi r^2[/tex]
We know the diameter is 20 inches and the height is 2 inches. We must find the radius.
The radius is half the diameter. r= d/2 r= 20 in /2= 10 inNow we know that:
[tex]r= 10 \ in \\h= 2 \ in[/tex]
Substitute the values into the formula. Also, plug 3.14 in for pi.
[tex]SA=2 (3.14)(10 \ in)(2 \ in)+ 2 (3.14)(10 \ in)^2[/tex]
Solve according to PEMDAS: parentheses, exponents, multiplication, division, addition, and subtraction.
Solve the exponent.
(10 in)²= 10 in * 10 in= 100 in²[tex]SA=2 (3.14)(10 \ in)(2 \ in)+ 2 (3.14)(100 \ in^2)[/tex]
Multiply all the numbers together.
[tex]SA=2 (3.14)(20 \ in^2)+ 2 (3.14)(100 \ in^2)[/tex]
[tex]SA=125.6 \ in^2+628 \ in^2[/tex]
Add.
[tex]SA= 753.6 \ in^2[/tex]
The surface of the cylinder is 753.6 square inches.
