Answer:
Step-by-step explanation:
Rewrite log16(0.25)
using the change of base formula.
Exact Form:
log(0.25)log(16)
Decimal Form:
−0.5
Answer:
A, B and F.
Step-by-step explanation:
The bill total + 20% of the bill total must be less than or equal to $60.
So we have the inequality:
x + 0.20x ≤ 60
1.20x ≤ 60
x ≤ 60/1.20
x ≤ 50 dollars.
2,180 - 150 • m
2,180- 150 • 6 =
2180- 900=m
1280=m
setup a simple algebraic equation and solve.
5x = 7x-28
-5x -5x
0=2x-28
+28 +28
28=2x
Now divide both sides by 2 and you get that she is 14
For the equation to work, you have to have the same number on both sides of the equal sign
so to find ?, you can do:
13 - 2 = 12 - ? Simplify
11 = 12 - ? Subtract 12 on both sides
-1 = - ? Multiply -1 on both sides
1 = ?
