Sweater: 1/3 = 0,333
Jeans: 3/5 = 0,6
1 – 0,6 – 0,333 = 0,067
So the 36$ represents 6,7% of all the money he had at first. (just for you to know 1 represents 100% of the money he had)
Now, you just have to use the rule of three
0,067 = 36
0,333 = x
(0,333•36)/0,067= 179,1$
The sweater costed 179,1$
Parallel lines has equal slopes.
Equation of the line 2x + y + 1 = 0 in slope intercept form is y = -2x - 1 with slope of -2. Therefore, the slope is -2.
180 miles because 45 minutes is three quarters of an hour so you multiply 3.75hrs times 48mi which equals 180 miles.
Answer:
x=4
Step-by-step explanation:
RS + ST = RT
5+ 2x-2 = 3x-1
Combine like terms
2x+3 = 3x-1
Subtract 2x from each side
2x+3-2x = 3x-1-2x
3 =x-1
Add 1 to each side
3+1 = x-1+1
4=x
