Answer:
D (210)
Step-by-step explanation:
120 times 1.75 equals 210
C. 3/2 divided by 3
Alina has 3/2 hours to complete her homework. She should divide her 3/2 hours by the 3 assignments to determine how much time she will spend on each assignment. This turns out to be 1/2 hours, or 30 minutes, on each assignment. 3/2 hours is the same thing as 90 minutes, so this answer makes sense. We want the time to be divided by the number of assignments, not vice versa.
12/10 = 1.2
4/10 = 0.4
1.2-0.4 = 0.8
Given that the quadrilaterals are similar, we know that:

Substituting the given values, we get:

Solving the above equation for x, we get:

Simplifying the above result, we get:
