Answer:
15
Step-by-step explanation:
Red : Blue :
3 8
We have 40 blue marbles
Multiply 8 by what to get 40
40/8 =5
So we need to multiply by 5
Red : Blue :
3*5 8*5
15 40
There are 15 red marbles
This means Square root (^1/2). this is kind of hard to read. anyways. 32^(1/2) separates into 4^(1/2) and 8^(1/2), which further separates into 4^(1/2) and 2^(1/2), root 4 becomes 2, their are two root 4's, so you get 2 x 2, and you are left with 2^(1/2) now why go to all this trouble. because now you can multiply the 4 you created (2x2) times, the 7... giving you 28*2^(1/2) now subtract it from the the other one with root 2. -5*2^(1/2), giving you 23*2^(1/2)-...idk what that last bit is. if its a odd number then this is the end of the problem, if you can get it to root 2. then do that and simplify.
Answer:
The number of shots Nick sunk was 8
Step-by-step explanation:
Let
x -----> number of shots that Nick sunk.
y -----> number of shots Nick missed
we know that
x+y=28
y=28-x -----> equation A
5x-2y=0 ----> equation B
substitute equation A in equation B and solve for x
5x-2(28-x)=0
5x-56+2x=0
7x=56
x=8
Find the value of y
y=28-x ----> y=28-8=20
therefore
The number of shots Nick sunk was 8
3x + 6
distribute the 3 to both of the places in the parentheses.
It would be less expensive if they are going for up to 7 months a year.
In order for those to be equal, they would need to go for 7.5 months. Since you can only round for months, I would say up to 7.
Equation: $100+$30x = $325.
