Answer: [tex]x = -5[/tex]
Step-by-step explanation:
If a product of 15 and an unknown number equals -75 the equation should look like this:
[tex]15x = -75[/tex]
Now to solve for x:
1. [tex]\frac{15x}{15} = \frac{-75}{15}[/tex]
2. [tex]x = -5[/tex]
The solution for x is -5.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation. Equal treatment should be given to each party.
Given:
The product of 15 and a number X is -75.
So, the expression is
15x = -75
Now, divide 15 on both side
15x/15= -75/15
x= -5
Hence, the value of x is -5.

Step-by-step explanation:

What is the correct answer?
Answer:
C) y = 10/3x - 5
Step-by-step explanation:
Slope intercept equation is y = mx + b:
m is the slope
b is y-intercept
When you read slope you can also read it as rise over run. Rise is move up or down on the y axis depending if number is negative or positive. Run is move left or right on x axis depending if number is negative or positive.
Example: y = [tex]\frac{10}{3} x - 5[/tex]
Start at the y-intercept which is -5. On graph you can see the line crosses the y axis at (0, -5). From this point rise 10 then run 3 you'll end up at point (3, 5). Connect the dots of the two points and you'll see a line like the one in the problem.
Jack wants to buy a piggy bank at 6000 dollars . Black Friday is coming at November 6th and there are 80%of all goods how much will he now pay ?
Answer: 1,200 dollars
Step-by-step explanation:
We know that the cost before the discount is 6,000.
The discount price is 80% off.
So, subtract 4,800 by 6,000 because 80% of 6,000 is 4,800.
Now, we have to add the two zeros. We get 1200.

Answer:
UNDEFINED
Step-by-step explanation:
change in y over the change in x is how you'd find slope, however, x is the same in both of these, making this a limitation not an equation, therefore the slope is undefined 18-18 = 0 -> Anything divided by zero as a slope is undefined.

2- A. 0.4
3- B. -2.8
4- C. n·6 - 12 = 60
Step-by-step explanation:
Heres the work in case teachers ask:
1. The given expression evaluates to ...
30÷2 + 2·7 = 15 + 14 = 29
A: 3(10÷2) + 2·7 = 3·5 + 2·7 = 15 + 14 = 29 . . . . . this will make it true
B: 30÷(6+2)·7 = (30/8)·7 = 210/8 = 26 1/4 . . . . . . ≠ 29
C: 3(10)÷(2+2)·7 = 30/4·7 = 210/4 = 52 1/2 . . . . . ≠ 29
D: (5+2)·7 = 7·7 = 49 . . . . . . . . . . . . . . . . . . . . . . . ≠ 29
2. You can divide the equation by 10 to find the appropriate value of x.
4/10 = 10x/10 = x . . . . . 4/10 matches choice A
3. The expression simplifies to ...
7.5 -10.3 = -2.8 . . . . . . matches choice B
4. "The product of a number and 6" is n×6. Twelve less is n×6 - 12. When that "is 60", the equation can be written ...
n×6 - 12 = 60 . . . . . . . . matches selection C

84 divided by 10.92 long division(with work)
Answer:
7.692
Step-by-step explanation:
Divide 84 by 10.92 to get 7.69230769231
Round 7.69230769231 to the nearest thousandth to get 7.692.
Answer: 7.69 rounded
Step-by-step explanation: The numbers go on further but I just rounded it to the hundredths. The full number if you want is 7.69230769231.
Now, Change the divisor 10.92 to a whole number by moving the decimal point 2 places to the right. Then move the decimal point in the dividend the same, 2 places to the right.
We then have the equations:
8400 ÷ 1092 = 7.69
and therefore:
84 ÷ 10.92 = 7.69
Both calculated to 2 decimal places.
0 0 0 7. 6 9
1 0. 9 2 |8 4. 0 0 0 0

Remember that it can keep going on for more decimal places, but this is to 2 decimal places so the answer to 2 decimal places is 7.69.

The absolute value of -3 is less than the absolute value of -7.
The absolute value of -3 is equal to the absolute value of -7.
.) The absolute value of -3 is greater than the absolute value of -7.
DONE
Answer: -3 is greater than -7 and the absolute value of -3 is less than the absolute value of -7.
Step-by-step explanation:
For NEGATIVE numbers, the closer the value is to 0, the greater it is. -3 is closer to 0 than -7 is, so -3 is greater than -7. For POSITIVE numbers, the further away the number is from 0, the greater it is. The absolute value of -3 is 3 and the absolute value of -7 is 7, and 7 is farther away from 0 than 3 is. So, the absolute value of -3 is less than the absolute value of -7. Hope this helps!

For each problem, explain or show your reasoning, a. 160 is what percentage of 40? b. 40 is 160% of what number? c. What number is 40% of 1602
Answer:
A. 160 Out of 40 is 400%./// B. The answer is 25/// C. The answer is 3905%
Step-by-step explanation:
( A ) One step solution:
You can easily find the answer in one step, just multiplying the part by 100 then dividing the result by the percentage.
So, 160 is 40% of = 160 X 100 = 400
40
( B ) The same thing as A but the numbers are switched
One step solution:
You can easily find the answer in one step, just multiplying the part by 100 then dividing the result by the percentage.
So, 40 is 160% of = 40 × 100 = 25
160
( C ) Working out a percentage increase or decrease between two numbers is pretty simple. The resulting number (the second input) is 1602 and what we need to do first is subtract the old number, 40, from it:
1602 - 40 = 1562
Once we've done that we need to divide the result, 1562, by the original number, 40. We do this because we need to compare the difference between the new number and the original:
1562 = 39.05
40
We now have our answer in decimal format. How do we get this into percentage format? Multiply 39.05 by 100?
39.05 x 100 = 3905%
160 is percentage of 40, 40 is 160% , number is 40% of 1602 are 64 , 64 and 640.8 respectively.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Problem A,
40% of 160 = 160 x 40 / 100
= 64
Problem B,
160% of 40 = 160 x 40 / 100
= 64
Problem C,
40% of 1602 = 1602 x 40 / 100
= 640.8
Therefore, 160 is percentage of 40, 40 is 160% , number is 40% of 1602 are 64 , 64 and 640.8 respectively.

Answer: infinite solutions
Step-by-step explanation:
(−3) (4) + (−3) (−3x) = 9x + −12
−12 + 9x = 9x + −12
9x − 12 = 9x − 12
9x − 12 − 9x = 9x − 12 − 9x
−12 = −12

Anyone can help me with this problem
Answer:
R=50 degrees
Step-by-step explanation:
All of the angle measures together are 180 degrees. You need to make an equation in order to solve this problem:
180= (3x+5) + (11x-1) + (5x+5)
You then combine like terms:
180= (3x+11x+5x) + (5-1+5)
180= 19x+9
Then, subtract 9 from 180:
171= 19x
Then, divide 171 by 19:
9= x
Finally, you plug the value of x into the equation representing angle R:
5 x 9 + 5
45 + 5
