Pls help need to get done

first you need to add the fractions then one you have gotten your answer you change it into a denominator then multiply each side

I hope this was helpful :)

5x/8 + 1x/5 = 99

We first find the common denominator

and then multiply the same number with the numerator

for the fraction 5x/8 we multiply the numerator and denominator with 5

25x/40

and for 1x/5 we multiply it with 8

8x/40

Now we just need to simply add these two

25x/40 + 8x/40

33x/40

33x/40 Thata your answer

hope it helps

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: 8

step-by-step explanation: if you add the possibilities 5 different flavor and 3 different sizes 5+3=8
