6x + 9 = 4x - 3
2x + 9 =-3
Multiply both sides by 2
- 4(5x-7)=-18
5x - 7 = 4.5
Multiply both sides by-4
8 - 10x = 7+ 5x
4 - 10x = 3 + 5x
Multiply both sides by 1
x = 4
5x =- 16
Add to both sides
- 4x
12x + 4 = 20x + 24
Add to both sides
3x + 1 = 5x + 6

Answer:
m=1/2
Step-by-step explanation:
y1= 1
y2=6
x1= -10
x2-0
m= slope
m= y2-y1/x2-x1
m=6-1/0 - - 10
m= 6-1/0+10
m=5/10
m=1/2

A piece of wire is 25 cm and has a weight of 10 grams. Another piece of the same wire is 30 cm long. Calculate the weight of the 30 cm piece of wire. working out please
Answer:
75 grams
Step-by-step explanation:
If 25 cm = 10 grams
Then 1 cm = 25/10
1 cm = 2.5 grams
To find 30 cm = 2.5 times 30 grams
30 cm = 75 grams
x-intercept=3, y-intercept=-4 put into slope intercept form
y = mx + c
y intercept= (0,-4) , x intercept = (3,0)
m = (y2-y1)/(x2-x1)
m = (0-(-4))/(3-0)
m = 4/3
0 = (4/3)(3)+ c
c = -4
Thus, the equation is y = 4/3 x -4

MP bisects ∠BMS. If m∠BMP = 2x + 9 and m∠BMS = 7x – 3, find the value of m∠PMS
Answer:
Step-by-step explanation:
If MP bisects ∠BMS, then the line MP divides <BMS equally;
The adition postulate if therefore true;
<BMP +< PMS = <BMS and <BMP = < PMS
The equation becomes;
<BMP +< BMP= <BMS
2 <BMP = <BMS
2(2x+9) = 7x - 3
4x+18 = 7x-3
collect like terms
4x-7x = -3-18
-3x = -21
x = 21/3
x = 7
Since <BMP = < PMS 2x+9
< PMS = 2(7)+9
< PMS = 14+9
< PMS = 23
Hence the value of < PMS is 23

Suppose you need to build a box with a surface area of 90 square feet. If the length is 5 feet and the height is
2 feet, what is the width of the box?
Answer:
Hi there!
Your answer is:
W=17.5feet
Step-by-step explanation:
We use the surface area form for a cuboid:
2h(l+w)=SA
Fill in the known values!
2(2)* (5+ W) = 90
Solve for W!
4*(5+W)=90
20+4w=90
-20
4w=70
/4
W=17.5feet
Calculate the means
95,84,31
70 is the mean
95+84+31 =210
210/3 = 70

Sports. The path of a particular punt follows the quadratic function where is the height of the ball in yards and corresponds to the horizontal distance in yards. Assume corresponds to midfield (the yard line). For example, corresponds to the punter's own yard line, whereas corresponds to the other team's yard line. a. Find the maximum height the ball achieves. b. Find the horizontal distance the ball covers. Assume the height is zero when the ball is kicked and when the ball is caught.
The question is incomplete. The full question is below.
The path of a particular punt follows the quadratic function
[tex]h(x)=\frac{-1}{8}(x-25)^{2}+50[/tex]
where h(x) is the height of the ball in yards and x corresponds to the horizontal distance in yards. Assume x=0 corresponds to midfield (the 50 yards line). For example, x=20 corresponds to the punter's own 30 yard line, whereas corresponds to the other team's 30 yard line.
a. Find the maximum height the ball achieves.
b. Find the horizontal distance the ball covers. Assume the height is zero when the ball is kicked and when the ball is caught.
Answer: a. Maximum height = 50
b. Horizontal distance = 40
Step-by-step explanation: A quadratic function has its maximum or minimum point on its vertex.
When the function is negative, function has a maximum point.
The quadratic function h(x) is written in vertex form, meaning the coordinate of vertex is explicit in the function.
General vertex form: [tex]f(x)=A(x-h)^{2}+k[/tex]
A is vertical scaling parameter
(h,k) are the coordinates of vertex
So, the quadratic function for the height for the ball:
[tex]h(x)=\frac{-1}{8}(x-25)^{2}+50[/tex]
shows its vertex:
(h,k) = (25,50)
a. The maximum height the ball achieves the maximum value corresponds to the y-axis, which means, maximum height is 50 yards.
b. Horizontal distance is when h(x)=0, so:
[tex]\frac{-1}{8}(x-25)^{2}+50=0[/tex]
[tex]\frac{-1}{8}(x-25)^{2}=-50[/tex]
[tex](x-25)^{2}=400[/tex]
[tex]x^{2}-50x+625=400[/tex]
[tex]x^{2}-50x+225=0[/tex]
Solving quadratic equation:
[tex]x_{1}=\frac{50+\sqrt{1600} }{2}[/tex] = 45
[tex]x_{2}=\frac{50-\sqrt{1600} }{2}[/tex] = 5
When ball is kicked, it is in position 5. When is caught, is position 45. So, distance the balls covers is 40 yards.

find the quotient 4/7 divided by 1/5
Answer:
2 6/7
Step-by-step explanation:
You have to use the KEEP CHANGE CHANGE method. When you do this you end up with 4/7*5/1 which equals 20/7 and you then change that into a mixed number and you have your answer!
HOPE THIS HELPS!
Answer:
The answer is 2 6/7
Step-by-step explanation:
First, you set up the problem.
[tex]\frac{4}{7} / \frac{1}{5}[/tex]
Next, you change the division sign into multiplication
[tex]\frac{4}{7} x \frac{1}{5}[/tex]
Then you flip the 1/5
[tex]\frac{4}{7} x \frac{5}{1} \\[/tex]
Afterward, you multiply fractions straight across.
[tex]\frac{4}{7} x \frac{5}{1} =\frac{20}{7}[/tex]
Finally, you will simplify your answer into a mixed number.
[tex]\frac{20}{7} = 2 6/7[/tex]

Steve will need to buy
bags.
Answer:
mark me brainlest
Step-by-step explanation:
7
packets
Explanation:
Steve needs to know how many groups of 12 there are in the 75 students.
75
÷
12
=
6
1
4
However, Steve can only buy full packets of 12.
He needs 7 packets of apples.
I he only buys 6, there will not be enough for all the 5th Graders.

Step-by-step explanation:
When you're asked to find f(n), locate n on the x-axis, then move up or down along the grid line until you meet the curve. Then move horizontally to the f(x) axis and read the value from that.
This process is illustrated in the attachment.
__
To find f(x) = n, reverse the process. Locate n on the f(x) axis, then move horizontally to the curve, then vertically to the x-axis. That is the value of x you're looking for.

Television sizes are determined by the length of their diagonal measure. Michael just bought a new television. The height of the television is 37 inches and the length is 71 inches.
Using the Pythagorean Theorem, what is the size of Michael’s new television? Round your answer to the nearest whole inch (whole number).
Part A: What parts of the right triangle have you been given? Are you looking for a leg or the hypotenuse?
Part B: Set-up your equation by substituting the correct numbers into the Pythagorean Theorem formula.
Part C: Solve for the missing length rounded to the nearest whole number. Remember to show ALL work for each step.
Part D: What is the size of the television rounded to the nearest whole inch (whole number)? REMEMBER: We’re looking for the length of the diagonal, as that is the measurement used to determine TV Sizes.
Answer:
see below
Step-by-step explanation:
given: size of television is height = 37 in, length = 71 in.
A. using Pythagorean theorem:
parts given are legs which is the sides
looking for the hypotenuse.
B. formula:
a² + b² = c² or H² + L² = D²
where H = height = 37
L = length = 71
D = diagonal (which is req'd)
C. D² = 37² + 71²
D = [tex]\sqrt{1369+ 5041}[/tex]
D = [tex]\sqrt{6410}[/tex]
D = 80 in (missing length)
D. size of television:
37 x 71 in
Diagonal is 80 in

4.8 Twitter users and news, Part I: A poll conducted in 2013 found that 55% of U.S. adult Twitter users get at least some news on Twitter (Pew, 2013). The standard error for this estimate was 2.6%, and a normal distribution may be used to model the sample proportion. Construct a 99% confidence interval for the fraction of U.S. adult Twitter users who get some news on Twitter, and interpret the confidence interval in context. (please round all percentages to 2 decimal places)
Answer: Required 99% confidence interval : (48.30%, 61.7%)
Step-by-step explanation:
Confidence interval for PROPORTION: [tex]p\pm z^* \times S.E.[/tex], where p = sample proportion , z* = two-tailed critical z-value and S.E. = standard error.
As per given: p=55%
Critical z-value for 99% confidence = 2.576
S.E. = 2.6%
Then, required confidence interval :
[tex]55\% \pm (2.576)\times 2.6\%\\\\\approx55\% \pm6.70\%\\\\=(55\%-6.70\%,\ 55\%+6.70\%)\\\\=(48.30\%,\ 61.7\%)[/tex]
Required 99% confidence interval : (48.30%, 61.7%)
