Answer:
x = 3.6
Step-by-step explanation:
3/5 = x/6
multiply both sides by 6
18/5 = x
as a decimal
x = 3.6
Answer:
X/12
Step-by-step explanation:
X - whole drywall
X/4 -quarters
X/4/3=X/12 fraction of a whole sheet is each of these small pieces
Answer:
42
Step-by-step explanation:
Answer:
1) 25/54 = 46%
2) 10/27 = 37%
3) 17/27 = 63%
4) 20/27 = 74%
5) 17/27 = 63%
6) 10/17 = 59%
Step-by-step explanation:
1) (50 male)/108 total) = 25/54
2) (40 thumbs down)/(108) = 10/27
3) (68 thumbs down or male) / (108) = 17/27
4) (80 thumbs down or female)/(108) = 20/27
5) (68 thumbs up)/(108) = 17/27
6) (40 thumb up female)/(68) = 10/17
I assume that this is a system of equations so I'll use the substitution method.
Make one of the equations equal an isolated variable and since x is already isolated just add -3y on both sides.
x-3y=-24
+3y +3y
x=3y-24
Substitute that in for the first equation.
2(3y-24)+9y=27
6y-48+9y=27
15y-48=27
+48 +48
------------------
15y=75
----- ----
15 15
y=5
Substitute y in the other equation and find x
x-3(5)=-24
x-15=-24
+15 +15
--------------
x=-9
