Answer:
12
Step-by-step explanation:
6 * x = 72
x = 72 / 6
x = 12
H = 3.
FIRST STEP:
<span>Add 1 to both sides to get rid of the -1 on the left side.
4h-1 = 3h+2
</span><span>4h-1 (+1) = 3h+2 (+1)
</span><span>4h = 3h+3
SECOND (FINAL) STEP:
Subtract 3h from both sides to get rid of the 3h on the right side.
</span>4h(-3h) = 3h+3 (-3h)
h = 3
Hope this helps, sorry if it's hard to understand :)
To get a number to decrease by 21% you multiply it by 0.79 (1-0.21)
r = 0.79
lox (x) = -5
rewrite the equation in exponential form:
10^-5 = x
10^-5 = 1/10000
1/10000 = 0.00001
That is the correct answer.
