What would 'x' be in the equation -3(x-2)=6?
Answers
Answer:
[tex]\boxed {\boxed {\sf x=0}}[/tex]
Step-by-step explanation:
To solve this equation, we must isolate the variable (x) using inverse operations.
[tex]-3(x-2)=6[/tex]
x-2 is being multiplied by -3. The inverse operation of multiplication is division, so we divide both sides by -3.
[tex]-3(x-2)/-3= 6/-3\\(x-2)=6 /-3 \\(x-2)= -2[/tex]
2 is being subtracted from x. The inverse operation of subtraction is addition, so add 2 to both sides of the equation.
[tex]x-2+2=-2+2\\x=-2+2\\x=0[/tex]
In this equation, x is equal to 0.

We move all terms to the left:
5x+15-(75-25x)=0
We add all the numbers together, and all the variables
5x-(-25x+75)+15=0
We get rid of parentheses
5x+25x-75+15=0

Find the equation of the line which passes through (0, 7) at a gradient of 3.
Answers
Answer:
y = 3x + 7
Step-by-step explanation:
Here, line is passing through the point (0, 7). It's x-coordinate is 0 and y-coordinate is 7
So, y-intercept (b) = 7
Gradient (or slope m) = 3
Equation of line in slope intercept form is given as:
y = mx + b
Plugging m = 3 and b = 7 in the above equation, we find:
y = 3x + 7
This is the required equation of line.

This year, a small business had a total revenue of $14,600. If this is 27% less than their total revenue the previous year, what was their total revenue the previous year?
Answers
Given:
The total revenue of this year = $14,600
This year revenue is 27% less than their total revenue in the previous year.
To find:
The total revenue in the previous year.
Solution:
Let x be the total revenue of the previous year.
This year revenue is 27% less than their total revenue the previous year.
Revenue in this year = Revenue in previous year - 27% of it
[tex]14600=x-\dfrac{27}{100}x[/tex]
[tex]14600=x-0.27x[/tex]
[tex]14600=0.73x[/tex]
Divide both sides by 0.73.
[tex]\dfrac{14600}{0.73}=x[/tex]
[tex]20,000=x[/tex]
Therefore, the total revenue in the previous year is $20,000.
