how many solutions 2x+3y=-3 and 3x + 5y = -9
Answers
We can find the solutions by simultaneously solving the two equations.
From first equation, the value of y comes out to be:
[tex]2x+3y=-3 \\ \\ 3y=-3-2x \\ \\ y= \frac{-3-2x}{3} [/tex]
Using this value of y in second equation, we get:
[tex]3x+5( \frac{-3-2x}{3} )=-9 \\ \\ 9x-15-10x=-27 \\ \\ -x=-27+15 \\ \\ -x=-12 \\ \\ x=12[/tex]
Using this value of x, we can find y:
[tex]y= \frac{-3-2x}{3}= \frac{-3-24}{3} =-9 [/tex]
Therefore, there is only one solution to the given equations is which is (12, -9)

what is the common ratio of the geometric sequence below? -96,48, -24, 12, -6,..
Answers
-96, 48, -24, 12, -6
Each term is divided by - 2 or multiplied by [tex] -\frac{1}{2} [/tex]
[tex] \frac{48}{-96} [/tex] = [tex] -\frac{1}{2} [/tex]
[tex] \frac{-24}{48} [/tex] = [tex]- \frac{1}{2} [/tex]
[tex] \frac{12}{-24} [/tex] = [tex]- \frac{1}{2} [/tex]
[tex] \frac-{6}{12} [/tex] = [tex]- \frac{1}{2} [/tex]
The common ratio is -[tex] \frac{1}{2} [/tex]
The common ratio of the given geometric sequence is [tex]-\frac{1}{2}[/tex], as each term is half the value and opposite in sign of the previous term.
The common ratio of a geometric sequence can be found by dividing any term by the previous term. In the given sequence, -96, 48, -24, 12, -6,..., let's divide the second term by the first term:
Common ratio (r) = [tex]\frac{48 }{-96} = -\frac{1}{2}[/tex]
This ratio will be consistent throughout the sequence. For example, dividing the third term by the second term also gives [tex]-\frac{24 }{ 48} = -\frac{1}{2}[/tex], confirming that the common ratio is indeed [tex]-\frac{1}{2}[/tex].

At a movie, 1/4 of the people in the theater were men, 5/8 were woman l, and the rest were children. If there were 100 more woman than children, what was the total number of people in the theater.
Answers
x---------------> number of men in the theater
y---------------> number of women in the theater
z---------------> number of children in the theater
T--------------> total number of persons in the theater
we know that
T=x+y+z
x=(1/4)*T
y=(5/8)*T----------> equation 1
z=T-[(1/4)*T+(5/8)*T]-----> z=T-(7/8)*T------> z=(8*T-7*T)/8------> z=(1/8)*T
z=(1/8)*T----------> equation 2
y=100+z--------> equation 3
I substitute (1) and (2) in (3)
(5/8)*T=100+(1/8)*T------> (5/8)*T-(1/8)*T=100--------> T=200 persons
the total number of people in the theater was 200 persons
number of men in the theater------> 200*(1/4)=50 men
number of women in the theater----> 200*(5/8)=125 women
number of children in the theater----> 200*(1/8)=25 children

Identify the variable and the categories represented in this problem. Set up and fill in a two-way table to represent the frequencies in this problem.
Answers
Identify the variable and categories
By reading the above statement, we can find that there are two variables and each variable has 2 categories. The variables and their categories are:
1) Class Number
This variable is further divided into 2 categories i.e. Class 9th and Class 10th.
2) Participation in Extracurricular activities
This variable is further divided into 2 categories based on if students participated or not.
Part b)
Set up and fill 2 way table.
Since, we have 2 variables and each variable has 2 categories the number of data cells will be 2 x 2 = 4 cells
There are total 100 students. 40 students are in class 10th. This means 60 students are in class 9th.Out of 40 students in class 10th, 18 students participate in at least one extracurricular activity. So remaining 22 students do not participate. 32 students from class 9th participate in extracurricular activities, this means the remaining 28 students do not participate. Based on this data, we can fill up the table as shown below
Find the number that is smaller than 5 5/12 by as much as 2 2/13 is smaller than 6 1/6
Answers
Answer: the number is x = 1 + 21/52
Step-by-step explanation:
we have
(5 + 5/12) - x = (6 + 1/6) - (2 + 2/13)
this means that x is smaller than 5 + 5/12 by the same amount as (2 + 2/13) is smaller than (6 + 1/6)
We can solve it directly, first solve the parentheses, put the whole numbers at one side and the fractions in the other side:
5 - 6 + 2 - x = -5/12 + 1/6 - 2/13
1 - x = -5/12 + 2/12 - 2/13
1 - x = -3/12 - 2/13 = -1/4 - 2/13 = -13/(4*13) - (2*4)/(4*13) = -21/52
x = 1 + 21/52

A computer screen consists of small rectangular dots called pixels. Find the number of pixels on a screen that has 600 rows with 700 pixels in each row. PLEASE HELP.
Answers
A = LW
A = 700 * 600
A = 420,000 square units
There are 420,000 pixels on the screen.
Hope this helps =)
Number of pixels = 420000 pixels
Explanation:
The pixels are covering the whole area of the computer screen. This means that to the number of pixels, we will simply need to get the area of the computer.
Number of pixels = area of computer screen = length * width
Number of pixels = 600*700 = 420000 pixels

Step 2: Cross multiply (20)(2.5) = ( 1 4 )(x)
Step 3: Simplify 50 = 1 4 x

Honi is looking at a map with a scale of 1/4 in. = 20 miles. She measured the distance from Niceville to Live Oak as 2.5 in. She found the actual distance between Niceville and Live Oak by following these steps:
Step 1: Set up a proportion 1/4/20 = 2.5/ x
Step 2: Cross multiply (20)(2.5) = ( 1/4 )(x)
Step 3: Simplify 50 = 1/4 x
Step 4: Solve for x, x = 250 miles
Which step, if any, contains a mistake?
we have that
Step 1: Set up a proportion 1/4/20 = 2.5/ x ----------> is correct
Step 2: Cross multiply (20)(2.5) = ( 1/4 )(x) ----------> is correct
Step 3: Simplify 50 = 1/4 x --------------------------------> is correct
Step 4: Solve for x, x = 250 miles ------------> is not correct
because in the step 3 we have ----------> 50=(1/4)*x
x=50*4----------> x=200 miles
the answer the option D) Step 4
The mistake is in Step 4 of Honi's calculation. The correct actual distance between Niceville and Live Oak should be 200 miles instead of the 250 miles that was stated in the original steps.
Explanation:The student's question pertains to setting up and solving a proportion to find the actual distance between two places using a map scale. The map scale given is ¼ in. = 20 miles. Honi measures a distance of 2.5 inches on the map. The steps to find the actual distance, using a proportion, should be evaluated for accuracy.
To set up the proportion correctly, we use the ratio of the map scale and compare it to the ratio of the measured distance to the actual distance (x). The correct proportion should be: (1/4 in.) / 20 miles = 2.5 in. / x miles.
Step 1 is correct, setting up the proportion based on the scale and measured distance. Step 2 involves cross-multiplying to find the relationship between the scale and the actual distance, which should yield (1/4) * x = 2.5 * 20. Step 3 should simplify this equation correctly, which would give us x = 2.5 * 20 * 4 = 200 miles. Therefore, Step 4 has a mistake because the solution provided should be 200 miles, not 250 miles as given.

A triangle shaped paper’s height is 18 cm and width is 10 cm. Find the hypotenuse of the paper.
Answers
The hypotenuse of the paper is 2√106 cm.
What is Pythagorean theorem ?
Hypotenuse ² = Height ² + Width ²
Know more about Pythagorean theorem,
The Pythagorean Theorem, also known as the Pythagoras Theorem, explains the relationship between the three sides of a right triangle. According to the Pythagorean theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a right triangle. Pythagorean triangles are the name given to the sides of a right triangle. Let's learn about Pythagorean theorem, formula, derivation and examples in detail.
The history of the Pythagorean theorem goes back to the ancient Babylonian and Egyptian era. The Greek mathematician Pythagoras of Samos introduced the Pythagorean theorem. Pythagoras was born in 570 BC. The Greek philosopher studied with other monks and formed a group of people; he finally stated the Pythagorean theorem. Even before Pythagoras, the ratio was shown on a Babylonian tablet 4000 years ago, but the theorem is published under the name of Pythagoras.
Here given, a triangle shaped paper’s height is 18 cm and width is 10 cm.
We want find the hypotenuse of the paper ?
Here, height of the paper = 18 cm and width of the triangle = 10 cm.
[tex] = {18}^{2} + {10}^{2} \\ = 324 + 100 \\ = 424[/tex]
So,
[tex]hypotenuse = \sqrt{424} \\ = \sqrt{2 \times 2 \times 2 \times 53} \\ = 2 \sqrt{2 \times 53} \\ = 2 \sqrt{106} \: cm[/tex]
Therefore,the hypotenuse of the paper is 2√106 cm.
