3. Simplify the expression.
4(2x - 3)
ASAP PLS HELP
Answer with step-by-step explanation:
(4 x 2x) - (4 x 3) = 8x - 12
Hope this was helpful!
Answer: 8x + -12
Explanation: Let's simplify this problem using the distributive property.
The first thing we want to do is change the minus to plus a negative.
Now we can distribute or multiply this 4 times
each of the terms inside the set of parenthses.
So we get 4(2x) + 4(-3) and this simplifies to 8x + -12.
Note that if you wrote your answer as 8x - 12, it means the same thing.
Multiple-choice test with 50 questions has five possible choices for each question. There are 4 marks for each correct answer, -1 mark for each incorrect answer, and 0 marks for each unanswered question. What is the total score of a student with 35 correct answers, 10 incorrect answers and 5 unanswered
Answer:
Total score of a student = 130 marks
Step-by-step explanation:
Marks for each correct answer = [tex]4[/tex]
Marks for each incorrect answer = [tex]-1[/tex]
Marks for each unanswered question = [tex]0[/tex]
Number of correct answers = 35
Number of incorrect answers = 10
Number of unanswered answers = 5
So,
Total score of a student [tex]=35(4)+10(-1)+5(0)=140-10+0=130[/tex] marks
Answer:
35 correct: 35x4= 140 marks
10 incorrect: 10x -1= -10 marks
5 unanswered: 5x0= 0 marks
140-10+0= 130 marks

fix-it-fast plumbing charges $25 for a house call and $50 for each hour spent on the job. do it right palm and charges $35 for a house call and $45 each hour spent on the job how many hours must be spent on the job in order for the charges of two plumbing companies to be equal
Answer:
2 hours
Step-by-step explanation:
variable x = hours
fix it fast: 25 + 50x
do it right: 35 + 45x
25 + 50x = 35 + 45x
subtract 45x from both sides
subtract 25 from both sides
(this action cancels out 45x on the right side and 25 on the left side so you can combine like terms)
50x - 45x = 35 - 25
5x = 10
divide by 5 on both sides
x = 2

1. Mother bought 20 meters of curtain material. She used 8 metres for the living room, 73
meters for the dining room, and the rest for the kitchen. How many meters did she use for the
curtain in the kitchen?
Given parameters:
Total length of curtains bought = 20m
She used 8m for the living room
She used 7m for the dining room
unknown:
Quantity used for the kitchen = ?
Solution:
Quantity used for the kitchen = Total length - (living room + dining room)
Input the parameters given solve;
Quantity used for the kitchen = 20 - (8 + 7) = 5m
The length of curtain used for the kitchen is 5m

Answer:
6)z=92 y=88 x=92
7)I think all are 90
8) 62
9) 73
10) 87
Step-by-step explanation:
6)y is congruent to 88 vertical angles
and y+x=180, 88+x=180, x=92
x is congruent to z vertical angles so both 92
7) y is congruent with 90 and all the other side when subtracted by 180 equal 90
8)180-118=62
9) 90-17=73
10) 72+21=93
180-93=87
During a game, the pittsburgh steelers converted 6 of 10 fourths downs into first downs. With only minutes left in the game, it is fourth down again and they must make a first down to continue their drive. What is the probability that they will make the first down?
Answer:
[tex]\dfrac{3}{5}[/tex]
Step-by-step explanation:
Given that:
Total Number of fourth downs = 10
Number of fourth downs converted to first downs = 6
Formula for probability of an event E can be observed as:
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]
Here, Let E be the event of getting a fourth down converted to first down.
So, Number of favorable cases = 6
Total Number of cases = 10
Therefore, the required probability is:
[tex]P(E) = \dfrac{6}{10} = \dfrac{3}{5}[/tex]

2x - (3-x) > x+1 solve
Answer:
x > 2
Step-by-step explanation:
Step 1: Write inequality
2x - (3 - x) > x + 1
Step 2: Solve for x
Distribute negative: 2x - 3 + x > x + 1Combine like terms: 3x - 3 > x + 1Subtract x on both sides: 2x - 3 > 1Add 3 to both sides: 2x > 4Divide both sides by 2: x > 2Here we see that any value x greater than 2 would work as a solution.

25. Willa purchases a vase for her kitchen
that is shaped like a cube and will hold 343
cubic inches of water. What are the
dimensions (length, width and height) of the
vase?
Answer:
7,7, and 7
Step-by-step explanation:
If she vase is cubical we know that all 3 dimensions are the same. This means that x^3 = 343. So we know the answer is the cube root of 343, which is 7
The dimensions of the cubic vase are 7 by 7 by 7.
What is a cube?A three-dimensional object with six congruent square faces is called a cube. The cube's six square faces all have the same dimensions.
Given that the volume of the cubic vessel is 343 cubic inches.
The formula for the volume of a cube of side length a is:
V =a³
Substitute V= 343:
343 = a³
Or, a = ∛343
a = 7
Hence, the dimensions of the cubic vase are 7 by 7 by 7.

I used google to search up exponential function and it showed a lot of graphs and they're all curved.
For an exponential function, Its graph is a smooth curve. Option 3 is correct.
What is an exponential function?It is defined as a function that rapidly increases and the value of the exponential function is always positive. It denotes with exponent y = aˣ, where a is a constant and a>1.
A smooth curve can be found on the graph of an exponential function, which uses exponents. In an exponential function, the rate of change is not constant. Exponential functions include the ones at y = 0.5x and y = 2x in the graph below.
Because the slopes of exponential functions are nonlinear and constantly changing, their graphs resemble curves rather than straight lines.
Hence, for an exponential function, Its graph is a smooth curve. Option 3 is correct.
