Answer:
a) 4
b) 
Step-by-step explanation:
<u>PART A</u>
Simplify the expression by solving out the square roots.
= 
You can cancel out the
on the top and bottom.
So, a should be 4.
<u>PART B</u>
Solve out the square root. The square root is pretty much the 1/2 power, so you can divide the exponents by half.
= 
You can subtract exponents to divide them. So the y variable becomes
, or
.
Then, the overall expression is
, or you can turn that into
.
Answer:
36.56 in
Step-by-step explanation:
perimeter is the sum of all sides
u add all the sides of the square by 6
6+ 6 + 6 + 6 = 24
circumference is the line around the circle
circumference = 3.14 x diameter
c = 3.14 x 4
c = 12.56
24 + 12.56 = 36.56
to the NEAREST HUNDREDTH????? ok welll thats alr
remember
5 or more, raise the score
4 or less, let it rest
this should be fine since the last 6 is alr in the hundredth place :)

Answer:
If your trying to solve for a, I believe this is the answer: a = 4b / (2 - c)
Step-by-step explanation:
2a - b = ac + 3b
First you want to group by like terms, so for "b" you are going to add "b" to both sides so that it cancels out on the left side and you now have all of your "b's" on the right.
2a = ac + 4b
next, you want to get the a's on the left side so you are going to subtract "ac"
2a - ac = 4b
Now, you need to factor the "a" out, and since its the greatest common factor among the "2a - ac" you are left with "a(2 - c)"
a(2 - c) = 4b
Finally divide both sides by "(2 - c)"
a = 4b / (2 - c)
and that's your answer
Answer:
160
Step-by-step explanation:
This is basically saying "8 is 5% of what number (total)"?
<u>Note:</u> 5% in decimal is 5/100 = 0.05
When translating a word statement into algebra, we need to note that "is" means "equal" and "of" means "multiplication".
Let's translate <u>"8 is 5% of what number (total)"</u> (letting total number of coins be n):
8 = 0.05 * n
<em>solving, gives us:</em>
<em>8 = 0.05*n</em>
<em>n = 8/0.05 = 160</em>
<em />
<em>Hence, total number of coins Mia has is 160</em>
