9) is 3. Drink = 3$. 18-3 = 15. 15 equals 5 candy bar so each bar is 3
Answer:
Step-by-step explanation:
2(5)(-5)-(5)^2
=−75
Answer:
28 units^2
Step-by-step explanation:
1. First, let's divide this figure into two shapes: a square and a trapezoid. (Look at the image below explanation for division).
2. Next, we should know the area formulas of the square and trapezoid.
- Square: , where s = side
- , where a and b = top and bottom and h = height
3. Solving Area of Square and Trapezoid
- . Area of square is 16
- . Area of trapezoid is 12.
- 16 + 12 = 28
Therefore, the area of the figure is 28 units^2.
Answer:
a:
b: 5
c: 8
Step-by-step explanation:
<em>Explanation for a: Making the equations</em>
Assuming h is the amount of half-page ads and f is the amount of full page ads, we can create the equations since the total cost will be 800$, and we have a total of 13 ads.
<em>Explanation for b: Solving for h</em>
We can now solve for one of the variables using elimination. Let’s multiply the expression by -75.
Great! Now let’s add the equations.
Adding these equations, we get
Divide both sides by -35, and we get .
<em>Explanation for c: Solving for f</em>
We can now substitute h inside the equation .
