Answer:
5
Step-by-step explanation:
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
ANSWER: Eliza is one year old.
If you have 150 total gift cards, and 130 are worth 5$, 15 are worth 50$, that would leave five 100$ gift cards for a sum of 150 gift cards.
All you would do is divide the 5/150 = 30
There's a 30% chance that someone will get a 100$ gift card.
x = 15 and y = 12
4x + 2 = 62 ( alternate congruent angles )
subtract 2 from each side
4x = 60 ( divide both sides by 4 )
x = 15
12y = 144 ( alternate congruent angles )
divide both sides by 12
y = 12
