Write an equation then solve the problem

1. 12 is 10 more than some number what is the number
2. A number is the product of 4 and -7 what is the number
3. A number divided by -15 is -4 what is the number
4. -48 is 6 times some number what is the number
5. A number is 3 more than the sum of -9 and -11 what is the number

1. x+10=12 x = 2

2. 4 x -7 = x x = -28

3. x\15 = -4 x=60

4. 6 x x=-48 x=-8

5. 3 + (-9 + -11) = x x = -17

Step-by-step explanation:

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
