Answer:
The answer is 15ab. You can just simply multiply the two given number
2(4x - 3)=3(x+8)
The equation above is the problem I’m stuck on, I’m in algebra two and it’s been awhile since we’ve gone over this type of equation.
Answer:
x = 6
Step-by-step explanation:
2(4x - 3) = 3(x + 8)
1. Distribute the 2 and 3 into the parentheses.
2(4x) + 2(-3) = 3(x) + 3(8)
= 8x - 6 = 3x + 24
2. Subtract 3x from both sides.
8x - 3x - 6 = 3x - 3x + 24
= 5x - 6 = 24
3. Add 6 on both sides.
5x - 6 + 6 = 24 + 6
5x = 30
4. Divide by 5.
5x ÷ 5 = 30 ÷ 5
x = 6

The answer is that an irrational number cannot equal a rational number.
What is an irrational number?Irrational numbers are all real numbers that are not rational numbers in mathematics. Irrational numbers, on the other hand, cannot be stated as the ratio of two integers.
Let a be a rational number and b be an irrational number. b = c - a, which means that b is rational. Since an irrational number cannot equal a rational number.

After translating the given statement, the inequality will be 2x - 3 ≥ -20.
What is inequality?Inequalities are mathematical expressions where neither side is equal. In inequality, as opposed to equations, we compare the two values.
Less than (or less than and equal to), larger than (or greater or equal to), or not similar to signs are used in place of the equal sign in between.

what is the answer to this question im having trouble 3 x 2 - x?
Answer and Step-by-step explanation:
3 x 2 - x = ? Well, if you simplify it's just 5x. But, if you are trying to solve this then you have to know what x is or what your answer is. But, if you're trying to solve 3 x 2 = x then x would equal 6. Of course, if you know the answer or what x equals then plug it in as such, let's say x = 2 then you would plug 2 in for x and solve, 3 x 2 = 6 - 2 = 4. But, if you are trying to solve for x then look at the answer, let's say it is 24 so, 3 x 2 - x = 24, x would equal -18.

What is the solution of 2x(x+7)=0 if you are factoring
Answer:
x= {0, 7}
Step-by-step explanation:
curtain investments compound interest at different intervals. What effect does the size of the compounding interval have on the yield of the investment?
As the compounding frequency increases, the yield increases as well. But there's a limit to that increase.
Consider depositing $100 into an account at 5% interest. Let's consider a timespan of 1 year. These values were picked arbitrarily.
Using the formula A = P(1+r/n)^(nt), we can find the various yield amounts when n varies
The table below shows how A changes based on the values of n. I've let P = 100, r = 0.05 and t = 1.
As n gets larger, the value of A slowly approaches 105.13 when you round to the nearest penny.
So eventually the investment yield hits a ceiling of some sort. We cannot make the investment grow forever in some fixed amount of time (in this case 1 year).
In order for the data in the table to represent a linear function with a rate of change of +5, what must be the value of a?
Answer:
a=18
Step-by-step explanation:
The value of a or m is 18 in the linear equation, y = 5x - 2.
What is the system of equations?One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.
Given:
The table represents a linear function.
The data is given in the attached image.
The general equation of the linear function is,
y = ax+b.
Where a is the slope and b is constant.
By using the first and the third points from the table to find the equation of the linear function,
When x = 3 and y = 13,
13 = 3a+b {equation 1}
When x = 5 and y = 23
23 = 5a+b {equation 2}
Solving the system of equation,
we get,
a = 5 and b = -2
So, the equation is,
y = 5x - 2
Now, x = 4
Then y = m = 20 - 2 = 18
Therefore, the value of m is 18.

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Cost 4.5 pound of beef = $14.40
So, the unit rate for beef
= 14.40 / 4.5
= $3.2
Hence, the cost of one pound beef is $3.2
