me this is 2 step equations

he rode 90 miles

Step-by-step explanation:

Take away 40 from 490 then you’d get 450 and divide that by 5 and then your answer would be 90

490-40=450

450/5=90

90 miles

Step-by-step explanation:

If you take $40 away from Lonnie's bill, you get 450. Then you divide $450 by $5, and the answer is 90. The answer 90 is the amount of miles

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

answer: b.36 feet
