Answer:The answer can be calculated by doing the following steps;
Step-by-step explanation:
4k - 3 = 2k + 5
+ 3 + 3
-------------------------
4k = 2k + 8
-2k - 2k
-------------------------
2k = 8
------ -----
2 2
k = 4
You can also do it this way:
4k - 3 = 2k + 5
- 4k - 4k
------------------------
-3 = -2k + 5
-5 - 5
------------------------
-8 = -2k
----- ------
-2 -2
4 = k
As you can see, you will get the same answer either way you figure it out :)
Answer:
8
Step-by-step explanation:
The radius is part of a 3-4-5 special right triangle.
The diameter is two times the radius, so 4*2=

Formula for trapezoid
A=h*(b1+b2)/2,
b1 an db2 are the two lengths of the sides
152 = 16*(b1+6)/2 = 8*(b1+6)=8*b1+48--> 8*b1=104, b1 = 104/8=13
A = 16*(6+13)/2=16*9.5=152
Answer:
Mary has 12 friends, and a total of 13 people including her. Or, she has 25 friends, and a total of 26 people including her.
Step-by-step explanation:
First, we know that 26 is divisible by 1, 2, 13, and 26 because (2x13) and (1x26) both equal 26 but we know that Mary has more than 1 friend and if Mary is also added to the group where the candy is divided, that means that 1 and 2 are both out because Mary has more than 1 friend so 1 cannot be the answer and if Mary has 2 friends, that means that the candy would have to be divided 3 ways which is not possible evenly so the answer is either 12 friends or 25 friends.
