Answer:
x=
3
/2
Step-by-step explanation:
12(5x−4.5)=36
(12)(5x)+(12)(−4.5)=36(Distribute)
60x+−54=36
60x−54=36
Step 2: Add 54 to both sides.
60x−54+54=36+54
60x=90
Step 3: Divide both sides by 60.
60x
60
=
90
/60
x=

Answer:
Step-by-step explanation:
The given expresion is:
(−2x + 4y)(3x − 7y)
We expand using the distributive property: (a+b)(c+d)=a(c+d)+b(c+d)
We apply this property to get:
We expand further to obtain:

Answer:
About 84.13%
Step-by-step explanation:
Using gaussian distribution function
f(t)=
T- 60
sigma- 10
we then consider the range between [0,70)
=.841345 or 84.13%
