3 quarters x 5 over 7

0.53

Step-by-step explanation:

3 quarters = 0.75

5/7 = 0.71

0.75× 0.71

Hey there!

3/4 • 5/7

= 3(5)/4(7)

3(5) = 15⮐ Solving for your NUMERATOR (TOP number)

4(7) = 28⮐ Solving for your DENOMINATOR (BOTTOM number)

= 15/28

15/28

Good luck on your assignment and enjoy your day!

add 5 subtract 1

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
