Answer:
x = -9

Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define Equation
3(x + 1) - 2x = -6
Step 2: Solve for x
Distribute 3: 3x + 3 - 2x = -6Combine like terms: x + 3 = -6Isolate x: x = -9Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 3(-9 + 1) - 2(-9) = -6Add: 3(-8) - 2(-9) = -6Multiply: -24 + 18 = -6Add: -6 = -6Here we see that -6 does indeed equal -6.
∴ x = -9 is the solution to the equation.

Answer:
C.) y=-2/3+4
Step-by-step explanation:
You can look at the y-intercept to find the equation really quickly!
For example, the line crosses the y-axis at the value of 4, therefore, the y-intercept is 4.
The only option with a y-intercept of 4 is C

Juan hires an electrician.
Juan pays a one-time fee of $30.
Juan also pays $45 for each hour the electrician works.
Write a function that can be used to find the total charge, c, Juan will pay when the electrician works,h, works
Answer:
c = 45h + 30
Step-by-step explanation
Hi! You know that you are trying to find the value of c, so you are going to set that as what would be your y value.
Now you know that you have to pay $30 as a fee no matter what, so you need to make sure that there is $30 attached to the equation without it being multiplied by anything.
Next, you know that it is $45 per hour, so you are going to multiply 45*h, where h is the number of hours the electrician works.
Hope this helps!
Edgar is scuba diving 50 feet below the water. He is swimming to the surface at a rate of 3 feet per second. Write an equation to represent his depth, d, after s seconds.
Fill in the blank

Answer:
I know this is late but the actual answer is d=3s+-50
Step-by-step explanation:
The reason is because he is swimming down, so yeah.

What is the solution to this equation? 7x + 3 = 10x - 5.4 Record your answer and fill in the bubbles on your answer document. Be sure to use the correct place value.
Answer:
Step-by-step explanation:
7x + 3 = 10x - 5.4
Bringing like terms on one side
3 + 5.4 = 10x - 7x
8.4 = 3x
8.4/3 = x
2.8 = x

What is the common ratio for this sequence? 40, 36, 32.4, 29.16 A) 1.1 B) 0.5 C) 2.2 D) 0.9
Answer:
D) 0.9
Step-by-step explanation:
The common ratio of a sequence is the amount you multiply a term by to get the next one. To find this number divide the second term by the first term, so 36/40. This will give you 0.9, to check your answer take the first term and multiply it by the common ratio a few times; you should get the exact sequence listed in the question.

How many of the first million positive integers share no common factors greater than 1 with 2020
9514 1404 393
Answer:
396,040
Step-by-step explanation:
Factors of 2020 are 2, 5, 101.
There are 1,000,000 / 1010 = 990 multiples of 2 and 5 and 101.
There are 1,000,000 / 505 -990 = 990 multiples of 5 and 101 only.
There are 1,000,000 / 202 -990 = 3,960 multiples of 2 and 101 only.
There are 1,000,000 / 10 - 990 = 99,010 multiples of 2 and 5 only.
There are 1,000,000 / 101 -990 -990 -3960 = 3,960 multiples of 101 only.
There are 1,000,000 / 5 -990 -990 -99,010 = 99,010 multiples of 5 only.
There are 1,000,000 / 2 -990 -3960 -99,010 = 396,040 multiples of 2 only.
So, the total number of multiples of any factor of 2020 is ...
990 +990 +3960 +99,010 +3960 +99010 +396040 = 603960
Then the number of integers in the first million that do not share any common factors greater than 1 with 2020 is ...
1,000,000 -603,960 = 396,040

The simplified expression is 3(x√2 + √x), which means that the answer is (C) x²√2.
What is an expression?In mathematics, an expression is a combination of numbers, variables, operators, and functions that can be evaluated to produce a numerical value or another mathematical object such as a polynomial, equation, or inequality.
We can simplify the given expression by factoring out the greatest perfect square factor under each square root symbol. For the first term, √18x³, we can factor out √9x², which is 3x√2. For the second term, √9x, we can factor out √9, which is 3. Thus, we have:
√18x³ + √9x = √(9x²⋅2x) + √(9⋅x) = 3x√2 + 3√x
We can then factor out 3 from both terms:
√18x³ + √9x = 3(x√2 + √x)
Therefore, the simplified expression is 3(x√2 + √x), which means that the answer is (C) x²√2.
