b.5x + 12x = 30
c.5x + 30 = 12x
d.12x + 30 = 5x
Answer:
c.5x + 30 = 12x
Step-by-step explanation:
Given :Mrs. Ramiriz is making pies to sell at the local farmer’s market. It costs her $5 to make each pie, plus a one-time cost of $30 for baking supplies. She plans to sell the pies for $12 each.
To Find: Which equation can be used to find the number of pies she needs to sell to break even?
Solution:
Let no. of pies be x
It cost her $5 to make each pie
so, cost of making x pies = 5x
Since there is a one-time cost of $30 for baking supplies.
So, total cost for her is 5x+30
If she sells each pie for $12
Then cost of pies = 12x
Now equation can be used to find the number of pies she needs to sell to break even:
5x+30=12x
The area of a parallelogram is 18 m².
Given that, a parallelogram has a base of 12 meters and a height of 1.5 meters.
We need to find the area of a parallelogram.
The area of a parallelogram can be calculated by multiplying its base with the altitude. The base and altitude of a parallelogram are perpendicular to each other as shown in the following figure. The formula to calculate the area of a parallelogram can thus be given as,
Area of parallelogram = b × h square units
Where b is the length of the base and h is the height or altitude.
Now, the area of a parallellogram=12×1.5
=18 m²
Therefore, the area of a parallelogram is 18 m².
