Please help I need practice on this but I don't understand this concept, so please explain your answer. I really want to understand but my teacher didn't explain it clearly. I will mark brainliest for the best answer, with an explanation. Please don't put a link or type in a random answer. I really legitimately need help. Thanks to anyone who gives an answer. :D - Luna
Solve using elimination.
–3x + y = 15
–3x + 7y = –3
(_,_)
Answer:
(-4 + 3)
Step-by-step explanation:
–3x + y = 15
(-1) –3x + 7y = –3
–3x + y = 15
+ 3x - 7y = 3
6y = 18
/6 /6
y = 3
–3x + 3 = 15
- 3 -3
-3x = 12
/-3 /-3
x = -4

Find the length of the third side. If necessary, write in simplest radical form.
3^2 + 3√3^2
7y+5z-2y+z
grade 7 math
Answer:
Step-by-step explanation:
7y+5z-2y+z
Group the two y and the two z together
7y-2y = 5y
5z+z= 6z
(a variable with out a number is = to 1)
so it would be 5y+6z

proportional or not proportional?
Answer:
Proportional
Step-by-step explanation:
The relationship is proportional because starting at (0,0) there's a constant rate between the number of plants and the number of roses. We can represent this proportional relationship as y=5x where k=5, the constant of proportionality.
Explain how the percent equation relates proportional quantities
the percent equation being
PART = PERCENT * WHOLE
Answer: This is the best I could find for you
Step-by-step explanation:
"When the ratio of part to whole is equal to the ratio of a percent to 100, shows a percent equal to an equivalent ratio, we call it a percent proportion. A percentage is a fraction expressed with 100 as the denominator. When two ratios are equal, they are said to be in proportion."

How do you find the probability of two events A and B when A and B are independent? dependent?
A.For independent events, find the probability of the first event, find the probability of the second event after the first event occurs, and then multiply. For dependent events, find the probability of the first event, find the probability of the second event, and then multiply.
B.For independent events, find the probability of the first event, find the probability of the second event, and then multiply. For dependent events, find the probability of the first event, find the probability of the second event after the first event occurs, and then multiply.
C.For independent events, find the probability of the first event, find the probability of the second event after the first event occurs, and then add. For dependent events, find the probability of the first event, find the probability of the second event, and then add.
D.For independent events, find the probability of the first event, find the probability of the second event, and then add. For dependent events, find the probability of the first event, find the probability of the second event after the first event occurs, and then add.
Answer:
I think it is A, but i am not sure, sorry
Step-by-step explanation:
Two events are independent if the result of the second event is not affected by the result of the first event. If A and B are independent events, the probability of both events occurring is the product of the probabilities of the individual events.
A. For independent events, find the probability of the first event, find the probability of the second event after the first event occurs, and then multiply. For dependent events, find the probability of the first event, find the probability of the second event, and then multiply.
Answer:
Probably A

Answer: He has made $72 this week
Step-by-step explanation:
We can set up the equation of Y = 9x where Y is how much he made and X is how many hours he worked.
We can simply plug in 8 hours for x to get Y=9(8) where Y=72.
When a number x is multiplied by 5, the result is 8 less than the result of multiplying a number y by 3. Which of the following equations correctly expresses the relationship between x and y?
A. 5x = 24y
B. 5x - 8 = 3y
C. 5x + 8 = 3y
D. 5x + 3y = 8
E. 5x = 3(y - 8)
Answer: C
