How is this supposed to be solved I don't get it (〒﹏〒)
Answer:
B ?
Step-by-step explanation:
Solve this system of equations without graphing. 5x+4y=24 and 2x-8y=36
Answer:
x= 7
y= -2.75
Step-by-step explanation:
It's a system of equations so you have to use elmination to get a varibale.
I elminiated the y by multipling 5x+4y=24 by 2 and combining the two equations.
So now we are on 12x= 84. solve
x=7
plug it back into any formula, I chose 2x-8y=36 and solve for y
and you get the answer, Voila!
Answer:
5x + 4y = 24 (-4/5y + 24/5)
2x - 8y = 36 (4y + 18)
Step-by-step explanation:
Add -4y to both sides 1) 5x + 4y (-4y) = 24 (-4b)
Divide both sides by 5 2) 5x/5 = -4y+24/5
3) x = -4/5y + 24/5
Add 8y to both sides 1) 2x - 8y (8y) = 36 (8y)
Divide both sides by 2 2) 2x/2 = (8y + 36)/2
3) 4y +18
The mean height of a group of students is 1.65 meter. Explain what this means.
"Mean" is the average number in a data set.
Since the mean height in a group of students is 1.65 meters, that is the average height in that group.
Best of Luck!

26•26^8 i’m not sure how to solve this
Answer:
26^9
Step-by-step explanation:
If x = 0, simplify the expression completely.
Answer:
You have to apply Indices Law :
[tex] {a}^{m} \div {a}^{n} ⇒ {a}^{m - n} [/tex]
So for this question :
[tex] \frac{ \sqrt[3]{x} }{ {x}^{ \frac{1}{8} } } [/tex]
[tex] = \sqrt[3]{x} \div {x}^{ \frac{1}{8} } [/tex]
[tex] = {x}^{ \frac{1}{3} } \div {x}^{ \frac{1}{8} } [/tex]
[tex] = {x}^{ \frac{1}{3} - \frac{1}{8} } [/tex]
[tex] = {x}^{ \frac{5}{24} } [/tex]

What is the value of 0.5 + 0.3? Write your answer as a fraction in lowest terms.
Answer: It's 5/6
I know because i did the work and got it right.
The value of 0.5 + 0.3 as a fraction in lowest terms is 4/5.
Given that is an addition operation of two decimal numbers 0.5 and 0.3, we need to solve it in lowest terms.
The value of 0.5 + 0.3 can be calculated by adding the decimal values together:
0.5 + 0.3 = 0.8
To express this result as a fraction in lowest terms, we can convert the decimal 0.8 to a fraction.
To do this, we write 0.8 as 8/10, since the decimal point is one digit to the right of the ones place.
Now, we can simplify this fraction by dividing both the numerator and the denominator by their greatest common divisor (GCD), which is 2:
8/10 = (8 ÷ 2) / (10 ÷ 2) = 4/5
Therefore, the value of 0.5 + 0.3, expressed as a fraction in lowest terms, is 4/5.

Incoming students at a certain law school have an average LSAT score of 163 and a Standard Devation (SD) of 8. Tomorrow, one of these students will be picked at random. You have to guess the score now; the guess will be compared to the actual score, to see how far off it is. Each point off will cost a dollar. (For example, if the guess is 158 and the score is really 151, you will have to pay $7).
A) Is the best guess 150, 163, or 170?
B) You have about 1 chance in 3 to lose more than ______. (LSAT scores range from 120 to 180; the average across all test-takers is about 150 and the SD is about 9. The test is re-normed from time to time, the data are for 2005).

Answer:

Step-by-step explanation:
Determine whether the following events are mutually exclusive.
Roll a die. Get a prime number and get an odd number.
Ask yourself: "Can I roll a prime number and an odd number at the same time?"
Since the answer is "yes it is possible" (eg: rolling a 3), this means the two events are not mutually exclusive. Mutually exclusive events have nothing in common.
In terms of a venn diagram, mutually exclusive events have no overlapping shared region.
Answer: The events are not mutually exclusivewhat’s the x value of PR=9x-31 and QR=43?
9x + -31 = 43
Reorder the terms:-31 + 9x =43
Solving-31 + 9x =43
Solving for variable 'x' .Move all terms containing x to the left,Add '31' to each side of the equation .
0 + 31 +9x = 43 + 31
Combine like terms:-31 + 31 =0
0 + 9x = 43 +31
9x = 43 + 31
Combine like terms:43 + 31 =74
9x = 74
Divide each side by '9'x = 8. 222222222

a car dealership sells 48 cars of the same model in one month. the average price of each car is $25,000 with a maximum variance of $3,000 due to additional options. what is the range of the total revenue that the car dealership makes for the months sales of this car model?
Answer:
Range= $144,000
Step-by-step explanation:
The least amount for each car is 22,000 and the highest is 25,000
so assuming the dealer sells all of them the lowest price, the revenue would be, $1,056,000 (that would be the lowest revenue) and assuming he sells all the cars at the highest price, the dealer will get a revenue of $1,200,000. So the lowest revenue is 1,056,000 and the highest revenue is 1,200,000. So to find the range subtract the highest revenue by the lowest and you’ll get $144,000.
Answer:
A. $1,056,000 <= x <= $1,344,00
Step-by-step explanation:
Plato answer is A. $1,056,000 <= x <= $1,344,00
