Answer:
b=49
Step-by-step explanation:
27+b=76
76-27= 49
b=49
Answer:
4 feet
Step-by-step explanation:
We know the the area of a triangle can be represented as 
.
Since the height is twice the base, we can substitute the value 
in as 
in the expression, making it 
. If the area is 16, we can make the equation
Now to solve for b.
Hope this helped!
Answer:
The answer would be B. 12 + 6n is greater than or equal to 30, so n is less than or equal to 3.
explanation:
I'm bad with explaining things, but I'll try my best to explain why this is the right answer.
12 + 6n ≥ 30, so n ≤ 3
let's start with the 12 at the beginning of the inequality, Annie already has $12, so the 12 in the inequality shows the amount of money she already has being added to the $6 per hour of babysitting she needs to do (n).
Now for the + 6n, the plus is there to show that the $12 Annie already has is being added to the 6n. The 6n then represents the $6 Annie makes each hour and the n represents how many hours she needs to babysit in order to get $30. The 6 is being multiplied by the amount of hours she needs to babysit to show how much money Annie would make. Then you add on the $12 she already has.
Annie then needs at least $30, but if she makes more than $30 then she will simply have more money than needed, therefore you use the greater than or equal to sign to show that she can have more money than just $30 after working.
I hope this helps, and sorry if my explanation is hard to understand lol.
I am sure you are trying to type
If that is it, then you should recall the law of exponents which says,
Let us share the exponent for each of them.
We now apply the law,
We now simplify to obtain,
If that is not the expression let me know so I will know how to help you
