Answer:
Can I be marked brainliest?
x = -1
Step-by-step explanation:
Switch it around
4 - 3x = 7
-3x + 4 = 7
Subtract 4 from both sides of the equation
-3x + 4-4 = 7-4
Simplify
-3x = 3
Divide both sides of the equation by the same term
-3x/-3 = 3/-3
x = -1
Answer:
-1
Step-by-step explanation:
7=4-3x Add like terms
-4 -4
3=-3x Now divide

A weather station on the top of a mountain reports that the temperature is currently 0°C and has been falling at a constant rate of 3°C per hour. If it continues to fall at this rate, find each indicated temperature.
Answer:
-6°C
-15°C
-1.5°C
Step-by-step explanation:
The computation is shown below:
in one hour the temperature falls by 3°C i.e.
= 0 - 3
= -3°C
In two hours
= 2 × - 3°C
= -6°C
In five hours
= 5 × -3°C
= -15°C
in half an hour
= 0.5 × -3°C
= -1.5°C

willie has 4 treasure chests which have a combined weight of 240 pounds. If each chest weighs at least 20 pounds what is the heaviest possible weight of one of the chests?
A. 177
B. 180
C. 217
D. 234
Answer:
B. 180
Step-by-step explanation:
There is a condition that each chest needs to be at least 20 pounds and we can use that to our advantage. Because we want one of the boxes to be really heavy, we need the other three to be really light. Let's set the heavy box as variable y. Set each of the other three boxes equal to 20. Because the combined weight is 240, then the equation so far is 240 = (20*3)+y.
Now, we can solve for y. 240-60 = 180, so the heaviest box has to be 180 lb.
write down an expression for the nth term of the following sequence
5, 11, 17, 23, ...
Answer:
[tex]a_{n}[/tex] = 6n - 1
Step-by-step explanation:
There is a common difference d between consecutive terms in the sequence
d = 11 - 5 = 17 - 11 = 23 - 17 = 6
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 5 and d = 6 , then
[tex]a_{n}[/tex] = 5 + 6(n - 1) = 5 + 6n - 6 = 6n - 1

A 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 questions?
Answer: 130 marks
Step-by-step explanation:
There are 4 marks for every correct answer and there are 4 marks for each correct answer:
= 35 * 4
= 140 correct marks
There are -1 marks for every incorrect answer and there are 10 incorrect answers:
= 10 * -1
= -10 marks
Total score = 140 - 10
= 130 marks
Answer:

a cinema has three screens last saturday there were 500 visitors
Answer:
200 visitors went to screen 1.
125 visitors went to screen 2.
175 visitors went to screen 3.
Step-by-step explanation:
We will find number of visitors who went to screen 1 by finding 40% of 500 as we are told that 40% of 500 visitors went to screen 1.
Therefore, 200 visitors went to screen 1.
Now we will find number of visitors who went to screen 2. We are told that 25% of 500 visitors went to screen 2.
Therefore, 125 visitors went to screen 2.
Now we will find the number of visitors who went to screen 3 by subtracting combined number of visitors who went to screen 1 and screen 2 from total number of visitors.
Therefore, 175 visitors went to screen 3.

Describe all numbers x that are at a distance of 4 from the number 9. Express this using absolute value notation.
Answer:
|x - 9| = 4
Step-by-step explanation:
All numbers x that are at a distance of 4 fro the number 9
Given two numbers a and B, the absolute distance between them is written as :
|a - b| = c
Hence all numbers x at distance of x from 9
|x - 9| = 4
{x : |x - 9| = 4}

Help please, 20 points! Which inequality represents the values of X that ensure triangle ABC exists?
Answer:
C.
Step-by-step explanation:
The inequality 1< x <5 represents the X values that ensure triangle ABC exists. The value of x is between 1 and 5.
How to find side of triangle ?This free triangle calculator computes the edges, angles, area, height, perimeter, median, and other values, as well as a triangle diagram.
When attempting to find the hypotenuse, we use our two known sides as a and b. It makes no difference which leg is a and which is b. Then we solve for c by squaring a and b and taking the square root of both sides.
Pythagoras theorem: If the sides of a right triangle are hypotenuse, perpendicular, and base, then the square of the hypotenuse side is equal to the sum of the squares of the base and perpendicular.
If leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root: a = √(c² - b²)If leg b is unknown, then. b = √(c² - a²)For hypotenuse c missing, the formula is. c = √(a² + b²)For given triangle,
AB + BC = AC
2x + 4 + 6x > 18

A circle has a radius of 6x9y5cm. What is the area of the circle in square centimeters?
12πx11y7
12πx18y10
36πx11y7
36πx18y10
Answer:The answer is the second option: 36πx^18y^10
Step-by-step explanation:
To solve this exercise, you must follow the proccedure below:
1. You have that:
- The formula for calculate the area of the circle is: A=πr² ("r" is the radius of the circle).
-The problem says that the circle has a radius of 6x^9y^5 (r=6x^9y^5)
2. When you substitute r=6x^9y^5 into A=πr², you obtain:
A=πr²
A=π(6x^9y^5 cm)²
3. By applying the exponents properties, you have:
A=36πx^18y^10 cm²

What is the measure of the obtuse angle?

mZR= (3x)
m25 = (6x)
O 18

© 216
Answer:
108 degrees
Step-by-step explanation:
Given the following angle measures in triangle QRS
m<Q = 1x
m<R = 3x
m<S = 6x
Note that the largest angle is the obtuse angle since they are always greater than 90 and less than 180 degrees
The sum of angle in a triangle is 180 degrees
m<Q + m<R + m<S = 180
1x + 3x + 6x = 180
10x = 180
x = 180/10
x = 18
The obtuse angle is 6x
Measure of the obtuse angle = 6x
Measure of the obtuse angle = 6(18)
Measure of the obtuse angle = 108 degrees
Hence the measure of the obtuse angle is 108 degrees
