49-17.50 then add that with 5 then add it in a promotion
Answer:
It depends on the equation.
If the bases are equal and the variables are only in the exponents, set the exponents equal.
If there are variables in the exponents, but you cannot set the bases equal, then use logarithms.
Example 1:
Here you have the same base on both sides. The variables are in the exponents. Set the exponents equal and solve for x.
2x + 5 = 9
2x = 4
x = 2
Example 2:
The bases are different, but you can make the bases equal using laws of exponents. Remember that 9 = 3^2.
Now you have equal bases, so the exponents must be equal.
2x = 12
x = 6
Example 3:
Here you can't make the bases equal, so you take the log of both sides and use laws of logs.
Recall that:
Answer:
only 2 packages of 1818 cookies
Step-by-step explanation:
If I want to buy only big packages
Then, i can buy exactly 3636 cookies buying 2 packages of 1818 cookies.
If i want to buy only mall packages
Then, there is no way to buy only small packages and get exactly 3636 cookies.
(with 55 packages i get 55x66=3630 and with 56 packages 56x66=3696)
If i want to buy a combination of both packages i can only buy one big package and the rest in small packages.
Then, there is no way to buy one big and the rest small packages and get exactly 3636 cookies.
(with one big package and 27 small packages we get 1818+27x66=3600 and with one big package and 28 small 1818+28x66=3666)
<em>T</em><em>hen</em><em>,</em><em> the only way to get 3636 cookies is with two packages of </em><em>1818</em><em>.</em>
