The complete question is
Susan and Steven are cousins. The sum of their ages is 33. The difference between three times Steven's age and half of Susan's age is 36. Find <span>the age of Susan and Steven
let
x-----> </span>Susan's age
y----> Steven's age
we know that
y+x=33-----> equation 1
3y-x/2=36----> multiply by 2----> 6y-x=72----> equation 2
adds equation 1 and equation 2
y+x=33
6y-x=72
-------------+
7y=105--------> y=15
x=33-y----> x=33-15----> x=18
the answer is
Susan's age is 18
Steven's age is 15
Answer:
41/60
Step-by-step explanation:
Convert the fractions into like denominators: 7/30 = 140/600, 9/20 = 270/600
Add: 140/600+270/600 = 410/600
Divide into a smaller fraction: 41/60
The perimeter of a two-dimensional figure is always the sum of its sides.
The exercise mat has a perimeter (P) of <u>36 feet</u>. ...
Let length be <em>L</em>, and width be <em>W</em>.
P = 36
L = 2w
P=2(l+w)=2·(12+6)=36
L = 12 feet
W = 6 feet
The answer is B (Sorry for the bad handwriting.)
