What should you substitute for x in the second equation (bottom equation) in order to solve the system by the substitution method
[tex]x = \frac{3-y}{3}[/tex]
The help is greatly appreciated!
Answer:
slope = 8
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 1, 10) and (x₂, y₂ ) = (0, 18) ← 2 ordered pairs from the table
m = [tex]\frac{18-10}{0+1}[/tex] = [tex]\frac{8}{1}[/tex] = 8
Answer:
8

Phil has two rectangular prisms. The height of the second prism is 1/2 times the height of the first prism. The lengths and widths of the two prisms are the same. Which best describes the volume of the second prism?
Question 9 options:
The volume is times the volume of the first prism.
The volume is 2 times the volume of the first prism.
The volume is greater than the volume of the first prism.
The volume is the same as the volume of the first prism.
The volume of the second prism is also ten times the volume of the first prism.
Let's assume that both prisms have:
width = 3 units
height = 4 units
Prism 1 length = 5 units
Prism 2 length = 50 units
Let's solve their respective volumes to compare...
Volume of prism 1 = length * width * height
= 5 * 3 * 4
= 60 units ^3
Volume of prism 2 = 50 * 3 * 4
= 600 units ^3
Prism 2/ prism 1 = 10
That means prism 2 is ten times the volume of prism 1.

Answer:
96 units
Step-by-step explanation:
You have to split it into parts then add all together. 3 x 7 equals 21 4 x 7 equals 28 and 5 x 7 equals 35. 4 x 3 equals 12. But you have to split that in half for the area of a triangle. So, 21 + 28 + 35 + 6 + 6 = 96

Answer:
i) y∝x => y = kx and k = 2.5
ii) When x = 7, y is 17.5
Step-by-step explanation:
If y is directly proportional to x then according to the question
y∝x which means y =kx where k is any constant
From the above example
8y=20x comparing it with y = kx
y = (20/8)x
y = 2.5x
Here k = 2.5
i) y∝x => y =2.5x
ii) if x=7 then y = ?
From above
y=2.5x
Put x = 7
y = 2.5 x 7
y = 17.5
The ratio of students who prefer comedic plays to students who prefer romantic plays in the drama club is 2 to 3. If all students in the drama club prefer either comedic or romantic plays, which statement must be true?
Students who prefer romantic plays make up 3/5 of the drama club.
Students who prefer romantic plays make up 2/3 of the drama club.
There are exactly 3 students who prefer comedic plays in the drama club.
There are exactly 5 students in the drama club.
Answer:
A
Step-by-step explanation:
2 to 3 means that the ratio of romantic students has a numerator of 3. If there is a numerator of 3 the denominator has to be 5 because 2+3 is five if the fraction is 3/5, then the answer is A.

Salman flips a fair coin 350 times.
Part A
How many times would you expect Salman to flip heads?
Part B
Was your answer to part a based on theoretical probability or relative frequency?
Explain.
Part C
How many times will Salman flip heads?
A 176
B176
C 165
DbYou really cannot tell for sure
Answer:
Part A- About 1/2(half) of 350 would be reasonable since there is only two options for all 350 flips.
Part B- Theoretical probability, since an experiment has yet to be conducted it can't be experimental.
Part C- a or b would be a good answer, unless one should be different.
camilla earned a grade of 80% on a math test that has 20 problems. how many problems on this test did the student answered correctly?
Answer:
16 questions
Step-by-step explanation:
80% of 100 is 80, so we take that and divide it by 5 and we get 16.
Answer:
16 out of 20
Step-by-step explanation:
IF you ever run into problems like this just go to a calculator and start dividing numbers by 20 like this example: 15 divided by 20 = .75 convert that into a percent and its 75%. Same with 16/20= 80%

Answer: Equivalent Fraction = 60/1
Equivalent Decimal = 60.00
Part 2: E
Step-by-step explanation: Part 1: 3/5%=60 so in fraction form it has to be 60 wholes and for decimals it has to be 60.00
Part 2: 20% of 150=30 and 1/4x120=50 so not A B=25 so not B 1/25x120=4.8 so not C and 1/4 divided by 120=0.00208333333 so not D and E=30 so its E. plz mark me brainliest.

Mrs. Phillips has some cans of peas, beans, corn, and carrots without labels. When a can is chosen randomly, the probability of picking a can of peas is 110, a can of beans is 310, and a can of corn is 12. What is the probability of picking a can of carrots? Select ALL that apply.
Answer:
55
Step-by-step explanation:
The probability of picking a can of carrots is 1/10.
What is the probability?The Probability in mathematics is the possibility of an event in time. In simple words, how many times that incident is happening in any given time interval.
Given:
Mrs. Phillips has some cans of peas, beans, corn, and carrots without labels.
When a can is chosen randomly, the probability of picking a can of peas is 1/10, a can of beans is 3/10, and a can of corn is 1/2.
The probability of picking a can of carrots,
= 1 - 1/10 + 3/10 + 1/2
= 1/10
Therefore, 1/10 is the probability.
