Evaluate log12 - log4 + log5 and can you explain it to me?
mario62 [17]
Remember some simple log rules

log(a)+log(b)=log(ab)
and
log(a)-log(b)=log(\frac{a}{b})

work from left to right

log(12)-log(4)+log(5)=
log(\frac{12}{4})+log(5)=
log(3)+log(5)=
log(3*5)=
log(15)

A sundae at an ice-cream shop costs $3, and each extra ounce of toppings costs
anyanavicka [17]

Answer:

The number of ounce of topping that can be get is 4 .

Step-by-step explanation:

Given as :

The cost of a sundae = $3

The cost for each extra ounce of toppings = $0.50

Let The number of ounce of topping = n

The total spending cost on sundae with n extra topping = $5

Now, According to question

The total spending cost on sundae with n extra topping = The cost of a sundae + The number of ounce of topping × The cost for each extra ounce of toppings

Or , $3 + n × $0.50 = $5

or, 3 + 0.50 n = 5

or , 0.50 n = 5 - 3

or, 0.50 n = 2

∴  n = \dfrac{2}{0.50}

I.e n = 4

So, The number of ounce of topping = n = 4

Hence The number of ounce of topping that can be get is 4 . Answer

Which of these is a simplified form of the equation 9y + 5 = 7 + 3y + 2y?
ArbitrLikvidat [17]
We just have to solve  to get a simplified answer

we have 
        9y + 5 = 7 + 3y + 2y 
       9y +5 = 7 + 5y 
       9y-5y= 7-5
       4y=2
so if we solve further we will not get the answer that is given in option 
so option d is the write answer
