4x + 3y = 26 3x - 2y=11
Answer:
x = 5
Step-by-step explanation:
2 (4x + 3y = 26)
3 (3x - 2y = 11)
8x + 6y = 52
9x - 6y = 33 [the 6y and -6y cancel out]
17x = 85 [divide both sides by 17 to find x]
x = 5
Step-by-step explanation:
Hey, there!!
Given,
4x + 3y = 26........(i)
3x -2y = 11............(ii)
Multiplying equation (i) by 2 and equation (ii) by 3 we get,
8x - 6y = 52
9x + 6y = 33
17x = 85 { cancelling 6y and -6y}.
[tex]x = \frac{85}{17} [/tex]
Therefore, x= 5.
Now, putting the value of x is equation (i)
4x + 3y = 26
4×5 + 3y = 26
20 + 3y = 26
3y = 26 -20
[tex]y = \frac{6}{3} [/tex]
Therefore, y = 2.

Question is below PLEASE HURRY I'M DESPERATE
Answer:
a) 15.5 cm
b) 37.2 cm
Step-by-step explanation:
For part a you would write 4(x+1) because perimeter is adding the sides and all sides of a square are equal. then you would set that equal to 66 and get 4(x+1)=66 and then distribute the 4 and get 4x+4=66 and then subtract the 4 from 66 and get 4x=62. Then you divide 62 by 4 and get 15.5.
For part b you do essentially the same thing but set it equal to 152.8 and get 4(x+1)=152.8 and then distribute the 4 to get 4x+4=152.8 then subtract the 4 and get 148.8 and then divide that by 4 and get 37.2.
Answer:
Step-by-step explanation:
a) Length = (x +1) cm
Perimeter of square = 66 cm
4 * length = 66
4* (x +1) = 66
Divide both sides by 4
[tex]\frac{4*(x +1)}{4}=\frac{66}{4}[/tex]
x + 1 = 16.5
Subtract 1 from both sides,
x = 16.5 -1
x = 15.5 cm
b) Length = (x +1) cm
Perimeter of square = 152.8 cm
4 * length = 152.8
4* (x +1) = 152.8
Divide both sides by 4
[tex]\frac{4*(x +1)}{4}=\frac{152.8}{4}[/tex]
x + 1 = 38.2
Subtract 1 from both sides,
x = 38.2 -1
x = 37.2 cm
If a dog moves 3 meters due East and then 4 meters due North, what will be the dispalcement of the dog?
Answer:
The displacement of the dog which is the shortest distance between the two points is 5 meters 53.13° North of East
Step-by-step explanation:
The given parameters are;
The dog's displacement due East = 3 meters
The dog's displacement due North = 4 meters
The displacement, D motion of the dog can be written in vector form as follows;
D = 3i + 4j
The magnitude of the displacement is given as follows;
[tex]\left | D\right | = \sqrt{(3 \ meters)^2 + (4 \ meters)^2} = \sqrt{25 \ meters^2} =5 \ meters[/tex]
The displacement is the shortest distance between two points
The direction is given tan⁻¹(4/3) = 53.13° North of East
The displacement of the dog which is the shortest distance between the two points = 5 meters 53.13° North of East.

Solve the following and round to the nearest thousandth.
0.25 (7.5)
[tex]x2 = \frac{9}{256} [/tex]
I don't understand this at all
It is an equation, telling you that left side of = is same as right side and asking you to solve it (figure out the x).
[tex]x^2=\frac{9}{256}[/tex]
Apply square root on both sides of the equation to get rid of power on x.
[tex]x=\pm\sqrt{\frac{9}{256}}[/tex]
Now simplity the square root.
[tex]x=\pm\frac{\sqrt{9}}{\sqrt{256}}=\boxed{\pm\frac{9}{16}}[/tex]

For a parade, attendance was rounded as 10,000 to the nearest hundred. What was the
greatest and least number of people that could have attended the parade? Explain your
answer.
Answer:
The least is 9950 and the largest is 10049 people
Step-by-step explanation:
If the number is rounded to the nearest hundred, the smallest number of people that could have attended the parade is 9950 because, rounding up the number 9950 to the nearest hundred would give 10000. If the number 9950 is decreased by 1 (9949), and rounded up to nearest hundred you won't get 10000. Hence the smallest number of people is 9950
While the largest number of people is 10049. 10049 to the nearest hundred is 10000. A further increase to the number 10049 would give a number greater than 10000 when rounded to nearest hundred.
The ideal gas equation says that the product of the pressure, P, and the volume of a gas, V, is equal to the number of miles of the gas,n, times the gas constant, R, times the temperature of gas,T.
PV=nRT
which of the following equations is equivalent to the ideal gas equation?
Algebra 1
Answer:
T=PV/nR
Step-by-step explanation:
Use the division property of equality to solve the ideal gas equation for T. Divide both sides of the equation by nR, then simplify.
PV=nPT
PV/RT=nRT/nR
PV/nR=T
Therefore, the equation below is equivalent to the ideal gas equation.
T= PV/nR

Effects of Shifting, Adding and Removing Data
Pamela works at the zoo. She was looking at some data showing the weight of their 4 giraffes. The mean of weight of the giraffes was 1,800 pounds and the median weight was 2,000 pounds. Then gets a baby giraffe that weighs 500 pounds. How would the addition of the baby giraffe affect the mean and median?
Chose one:
• Both the mean and median increased.
• Both the mean and median decreased.
• The mean increased, but the median decreased.
• The median increased, but the mean decreased.
Answer: Both the mean and median decreased.
Step-by-step explanation:
The addition of the 500 lb baby elephant will have a huge impact on the mean, since you'll be finding the average (adding all numbers then dividing). So the only logical answer would be the chosen. The median will most likely either decrease or stay the same, but since staying the same isn't an option for the median, it's most likely going to be decrease.

Complete question :
Vanessa and Zack are playing a game where the player with the lower score wins. At the end of the game, Vanessa has a score of -3 5/8 and Zack has a score of -3 2/3. Which statement explains who won?
Vanessa won. If you compare the decimal equivalents of their scores, -3.625 < -3.666.
Vanessa won. If you compare the decimal equivalents of their scores, -3.666 < -3.625.
Zack won. If you compare the decimal equivalents of their scores, -3.625 < -3.666.
Zack won. If you compare the decimal equivalents of their scores, -3.666 < -3.625
Answer: Zack won. If you compare the decimal equivalents of their scores, -3.666 < -3.625
Step-by-step explanation:
Given that :
Player with the lowest score wins ;
Vanessa's score = - 3 5/8
Zack's score = - 3 2/3
Converting to decimal:
Vanessa :
-3 5/8 = - 29 /8 = - 3.625
Zack:
-3 2/3 = - 11/3 = - 3.666
Comparing the scores :
From the negaryce side of a number line :
-3.666 comes before - 3.625, hence, - 3.666 is lower or lesser than - 3.625
-3.666 < - 3.625, hence Zack won
Answer:
D. Comparing the decimal equivalents of their scores shows that Zack won because -3.6 (line over 6) if less than -3.625.
