Answer:
D. Subtract 4 from both sides
Explanation:
I just learned about quadratic equations in school. The first step of solving quadratic equations is to make sure it is in standard form and equal to 0.
Standard form:
ax^2 + bx + c = 0
The answer is 16 cm (or 0.16 m).
The scale is the ratio of the model to the real thing.
So, in the scale 1:50, the model is 1, while the real thing is 50.
Now, just make a proportion:
the model : the real thing = the model dimension : the real thing dimension
1 : 50 = x : 8m
From here:
x = 8m * 1 / 50 = 0.16 m = 0.16 * 100 cm = 16 cm.
The fraction computed shows that the cups of sugar that can be used based on the flour will be B. 4 1/2 cups.
<h3>How to calculate the fraction?</h3>
From the information, Jonah used 1 1/2 cups of brown sugar and 2 1/3 cups for flour.
Therefore, the cups of sugar needed will be:
= 1.5/2.33 × 7
= 4.5 = 4 1/2.
