Answer:
Step-by-step explanation:
$760(1.023) = $777.48
2x^2=50
/2. /2
X^2=25
To get x alone you have to square root the ^2 to cancel it out , and what you do to one side you must do to the other. This means you also have to square root 25
The square root of x^2 is x and the square root of 25 is 5
The answer is x=5
The answer is 18.31 because 55/4 is 13.75
Then 129 degrees minus 90 degrees is 39 degrees so
He sold 28 at 0.75 cents and sold 21 at 0.99 cents.
0.85 is between 0.75 and 0.99 so he sells between 21 and 28 donuts.
0.85 is closer to 0.75 ,so the number should be closer to28.
The answer should be b)25
Answer:
x = - 4
Step-by-step explanation:
A line perpendicular to the x- axis is a vertical line parallel to the y- axis.
The equation of a vertical line is
x = c
where c is the value of the x- coordinates the line passes through
The line passes through (- 4, - 2) with x- coordinate of - 4, thus
x = - 4 ← equation of perpendicular line
