check A and C
Step-by-step explanation:
Look at the left side of the polygon. Since they are both real numbers, we can use those to set up a proportion:
16:12=(x-1):6
Now, we can cross multiply and solve:
96=12(x-1)
96=12x-12
108=12x
9=x
The value of x is 9

X = Juan's age
y = Eliza's age
Some key words/phrases we can use to help us make the equation are:
-is (whatever comes after this word usually equals the end result, or what it equals)
-two years younger
-than
-half her brother's age
.
just break it down :)
x/2 (half her brother's age) - 2 (two years younger) = y (Eliza is...)
| basically,
v
x/2 - 2 = y
So if Juan is 6, then we need to plug in 6 for x.
6/2 - 2 = y
3 - 2 = y
1 = y
