Translate the sentence into an equation.
four less than a number is 17.
which equation is correct?
x – 17 = 4
x – 4 = 17
x + 4 = 17
x + 17 = 4

Let the number = X

Then to get four less you need to subtract 4 from x so you have X-4.

Then that equals 17, so the equation would be:

x - 4 = 17

a. she will receive a refund of $278.

step-by-step explanation:

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
