Answer: 5x+(-20)=-15x Step-by-step explanation:
They should subtract $ -20 because they went behind on how much they planned to save. Now this question can be tricky because some might say they lost 0 because they already had an extra $20 but it is only asking for the month of February and is only asking for each month not the entire year.
1. ANSWER: You can solve an area of a triangle by the base and height by using the formula: A=1/2*b*h, where A= Area, b= base, and h=height.
2. ANSWER: First, use the formula: A=1/*b*h. Then substitute those variables to get A=1/2*15.25*18. Then, solve to find the area. 15.25*18=274.5. 1/2*274.5=137.25.
Therefore, the answer is Area=137.25 inches squared!

Step-by-step explanation:
we know that
The volume of a cone is equal to

Solve for the radius r
That means-----> isolate the variable r
Multiply by 3 both sides

Divide by
both sides

square root both sides
