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.
<span>Distance is equal to rate times time, and time is the unknown in this instance. To find time, divide distance by rate. In this case, Joe wants to use a rate five miles per hour less than his planned speed of 75 miles per hour, which is 70. Dividing 310 miles by 70 miles per hour yields an expected travel time of 4.4 hours.</span>
Answer:
A
Step-by-step explanation:
20 x 2 = 40
30 x 2 = 60
X= my age
500-3x=230
500-3x-230=230-230
270-3x=0
270-3x+3x=0+3x
270=3x
270/3=3x/3
x=90
you are 90 years old
Consider a right triangle in which one of the angles 
satisfies
That is, the side opposite occurs in a ratio of 3 to 5 with the hypotenuse. The side adjacent to then occurs in a ratio of 4 to 5 with the hypotenuse. In other words,
because
Then in this triangle,
