Answer:
b= 3a-c
Step-by-step explanation:
Solve for b.
a= 1/3(b+c)
multiplying both sides by 3.
3a= b+c
subtract c from both sides.
3a-c=b
or
b= 3a-c
Answer:
Area= 4,200 square feet
Step-by-step explanation:
If I read your question correctly, I'm assuming the dots (".") mean a multiplication sign ("x").
If they are all being multiplied, use PEMDAS to solve this. First, find to value for any exponents you have (in this case, it's and ).
Now that you have the values for these two exponents, multiply all the numbers together.
8 x 3 x 25 x 7 = 4,200
25 out of 65 people are wearing red, if there are 65 people at the party and only 25 are wearing red you would find the percentage by dividing 65 by 25 which equals to 2.6%
i hope this is correct im not great at math but i hope this helps
