Her brother joe made $52.08. First you need to make the percent into a decimal, like this 86% => .86. Then multiply .86 to $28. After that add what you got to $28.
The answer is A because if you go from each point on Q to R it is 7 units away
The equation of line with undefined slope and x - intercept -7 is x = -7
<em><u>Solution:</u></em>
Given that the slope of line is undefined and the x intercept is -7
To find: Equation of line
If a line has undefined slope, then it is a vertical line
A vertical line has undefined slope because all points on the line have the same x-coordinate
<em><u>The equation of a vertical line always takes the form:</u></em>
x = b
where, "b" is the x - intercept
Given x - intercept is -7
<em><u>Thus the equation of line is:</u></em>
Therefore, the equation of line is found
Answer:
The tip was 7.77 dollars, which represent 18.5% of the value of the bill
Step-by-step explanation:
Dollars paid as tip
$49.77 - $42 = $7.77
$42 represent 100% of the bill
$7.77 ---------------x
x = (7.77/42)*100% = 18.5%
ANSWER:
x=4 and y= -1
Explanation:
Add these equations to eliminate y:
4x=6
Then solve 4x =16 for x:
4x=16
4x/4 = 16/4 (divide both sides by 4)
x=4
Now that we have found x lets plug it back in to solve for y.
Write down an original equation:
x-3y=7
Substitute 4 for x-3y=7:
4-3y=7
-3y+4=7 (simplify both sides of the equation)
-3y+4+ (-4) = 7+ (-4) (add -4 to both sides of the equation)
-3y = 3
-3y/-3 = 3/-3 (Divide both sides by -3)
y= -1
