Solve the following system of equations algebraically
-24-8x=12y
1+5/9y=-7/18x

Answers

Answer 1
-24 - 8x = 12y
Divide by 12
y = -2/3x - 2

1 + 5/9y = -7/18x
Subtract 1
5/9y = -7/18 - 1
Divide by 5/9, or multiply by 9/5
y = -7/10x - 9/5

Find the x-value they intersect at...
-2/3x - 2 = 7/10x - 9/5
Add 2
-2/3x = 7/10x + 1/5
Subtract 7/10x
(-20/30x - 21/30x) = 1/5
-41/30x = 1/5
Divide -41/30
x = -6/41

The last calculator correctly shows (6.47×10⁻¹⁵)/(3.36×10⁻²⁹).

What are some rules of exponents?

Some common rules of exponents are

a^b/a^c = a^(b - c),

a^b.a^c = a^(b + c).

We can only add and subtract exponents only when we have the same base.

Given, (6.47×10⁻¹⁵)/(3.36×10⁻²⁹).

Here we have base 10 raised to some power.

So,  (6.47×10⁻¹⁵)/(3.36×10⁻²⁹).

=  (6.47×10⁻¹⁵⁻⁽⁻²⁹⁾)/(3.36).

=  (6.47×10⁻¹⁵⁺²⁹⁾)/(3.36).

= (6.47×10¹⁴)/(3.36).

So, the last calculator correctly shows (6.47×10⁻¹⁵)/(3.36×10⁻²⁹).

twenty-five is the quotient of a number y and 3.5 (write as algebraic expression)

Answers

The algebraic expression that represents the statement 'twenty-five is the quotient of a number y and 3.5' is written as (y / 3.5) = 25.

An explanation of an algebraic expression representing the quotient of a number y and 3.5.

The student is asking to express the statement "twenty-five is the quotient of a number y and 3.5" as an algebraic expression. In algebraic terms, the quotient of y divided by 3.5 is represented by[tex](\frac{y}{3.5})[/tex]or (y / 3.5).

Therefore, the complete algebraic expression that represents this statement is (y / 3.5) = 25.

The algebraic expression for 'twenty-five is the quotient of a number y and 3.5' is 25 = y / 3.5. To find y, you multiply 25 by 3.5.

The algebraic expression that represents the statement 'twenty-five is the quotient of a number y and 3.5' is written as 25 = y / 3.5.

To solve for y, you would multiply both sides of the equation by 3.5 to isolate y. This would give you: y = 25 x 3.5.

Mia played in two softball games one afternoon. the first game lasted 42 minutes the second game lasted 5/3 times longer than the first game. how long did Mia's second game last?

Answers

1st game was 42 minutes....2nd game was 5/3 times longer....so we multiply

5/3 * 42 = (5 * 42)/3 = 210/3 = 70 minutes....so the 2nd game was 70 minutes or 1 hr and 10 minutes
42 x 5/3= 70
70min= 1hr 10min

Find the outlier of the set of data 80,71,75,69,74,17,82

Answers

17 is the outlier because it is not very close to the other numbers

Answer:

The Outlier is 17.

Step-by-step explanation:

Since 17 is far from other numbers of data set. So, it is an outlier.

Also all other numbers in the data set lie between 69 to 82. But 17 is distinct from other numbers. Hence it is an outlier.

Further, Outlier is the observation which is distinct or has a large distance from other observation. Also, Data set is much affected by the outliers.

A trick coin is made such that when it is tossed there is a 20% chance of heads landing face up and an 80% chance of tails landing face up. If the coin is tossed twice, what is the probability that the coin will land with heads facing up both times?

Answers

P( heads on one toss) = 0.20

P  ( 2 heads)  = 0.20 * 0.20  = 0.04   or 4%

Answer:  4 %

Step-by-step explanation:

According to the question,

20% chance of heads landing face up

Therefore, probability of getting a head, [tex]P(H) = \frac{20}{100} = \frac{1}{5}[/tex]

The probability of getting tail, [tex]P(T) = \frac{80}{100} = \frac{4}{5}[/tex]

Thus, the  probability that the coin will land with heads facing up both times

= [tex]\frac{1}{5}\times \frac{1}{5}[/tex]

=   [tex]\frac{1}{25}[/tex]

=   0.04 or 4 %

Thus the required probability is 4 %.

Which expression represents this word phrase? seven less than the quotient of x and 9 x−7 9 x÷ 9 7 (x÷9)−7 (9÷x)−7

Answers

The expression that represents 'seven less than the quotient of x and 9' is written as (x / 9) - 7, translating the operations of division and subtraction from the word phrase to algebra.

The word phrase 'seven less than the quotient of x and 9' translates to an algebraic expression by identifying the key terms: 'quotient' refers to division, while 'less than' indicates subtraction.

Specifically, the quotient of x and 9 is expressed as (x \/ 9), and to represent 'seven less than' this quotient, we subtract 7 from it. Thus, the corresponding mathematical expression is (x \/ 9) - 7.

a package of 5 pairs of insulated socks costs $41.45. What is the unit price..... how would I do the math

Answers

You would divide 41.45 by 5 and the answer would be 8.29

Final answer:

The unit price for the insulated socks is found by dividing the total cost of the package, $41.45, by the number of pairs, which is 5. The unit price per pair of insulated socks is $8.29.

Explanation:

To calculate the unit price of the insulated socks, you would divide the total cost of the package by the total number of pairs in the package. Since the package contains 5 pairs and costs $41.45, you would perform the following calculation:

Identify the total cost of the package: $41.45.

Identify the number of pairs in the package: 5 pairs.

Divide the total cost by the number of pairs to find the unit price: $41.45 ÷ 5 = $8.29 per pair.

Therefore, the unit price per pair of insulated socks is $8.29.

The property of one permits you to multiply or divide the numerator and denominator of a fraction by the same number without changing the value of the fraction. Is there a property of one for addition? Support your answer using examples

Answers

There is not a property of "1" for addition, but the identity property in this case uses "0" instead. If a number is increased by 1, the value will necessary be increased or decreased by the amount added or subtracted. However, if the number either adds or subtracts zero, then value will be left unchanged. Examples: 3+1 = 4, but 3+0 = 3,

Marion Middle School has 600 students. Mike surveys a random sample 7 of 30 students and finds that 7 of them play a musical instrument. How many students at the school are likely to play a musical instrument?

Please explain how as well.

Answers

So if 7/30 students plays an instrument then you'll need to set up an equation for this. The equation you'd use would be:
7/30 = x/600
Then, cross multiply to get:
30x = 4200
Lastly, divide each side by 30 and:
x = 140 students play a musical instrument

Hope this helps!! :)
Do a proportion
7/30=x/600
1. Cross multiply
7x600=4200
30•X= 30x
30x=4200
Divide each side with the number with the variable.
30x/30=4200/30
X=140
