X < 14
Ur welcome...
Its pretty basic
Yes, 1/2 is equivalent to 4/8, because 4/8 reduced to simplest form is 1/2.
Answer:
a = 5 1/3
Step-by-step explanation:
a+b+b = 24
a + 2b = 24
b-a =4
a = b - 4
b - 4 + 2b = 24
3b = 24 + 4
b =28/3
substitute this in a = b - 4
a = 28/3 - 4
a = 28/3 - 12/3
a = 16/3
a = 5 1/3
Answer:
B. -4
Step-by-step explanation:
We want to find x such that f(x)=18.
We need to therefore solve 9x+54=18 forx.
9x+54=18
Divide both sides by 9:
(9x+54)/9=18/9
9x/9+54/9=18/9
Simplify:
x+6=2
Subtract 6 on both sides:
x=2-6
Simplify
x=-4.
So f(-4) should have value 18.
Let's check.
f(x)=9x+54
f(-4)=9(-4)+54
f(-4)=-36+54
f(-4)=18
So the answer is B.
