2 the answer is two I put it in the calculator
We simplify the equation to the form, which is simple to understand
5(3+k)=45
Reorder the terms in parentheses
+(+15+5k)=45
Remove unnecessary parentheses
+15+5k=+45
We move all terms containing k to the left and all other terms to the right.
+5k=+45-15
We simplify left and right side of the equation.
+5k=+30
We divide both sides of the equation by 5 to get k.
k=6
Step-by-step explanation:
Since we have given that
Amount of pay rate =$21
If she marked up by 78.7% , so it becomes
So, our amount for pay rate becomes
Now, he said he made a profit of 10%,so it becomes
So, our new pay rate becomes
This is the step through which we can get $41.28.
Use the formula 0 = b^2-4ac
0 = -b^2-4(2)(-9)
0 = -b^2+72
b^2 = 72
b = square root of 72
b = 2 real numbers
The correct answers are number two, and number six
