Raphael had 5 hits in 7 at bats. If he continues this pattern, how many hits will he have in 210 at bats?

devlian [24]

So it tell us that he is able to get 5 hits out of 7 and to find how much he could make if 210 chances
$\frac{5}{7} = \frac{x}{210}$

We solve what can be solved
$0.7 = \frac{x}{210}$

Then we leave our variable alone
$0.7 *210=x$

Last we solve
$x=147$

In this case we can see that he could make 147 hits out of 210 bats.

3. Complete the square for 3x2 - 6x = 21.<br> Help

PSYCHO15rus [73]

Answer:

x=1+2√2 or x=1−2√2

Step-by-step explanation:

Let's solve your equation step-by-step.

3x2−6x=21

Step 1: Since the coefficient of 3x^2 is 3, divide both sides by 3.

3x2−6x

x2−2x=7

Step 2: The coefficient of -2x is -2. Let b=-2.

Then we need to add (b/2)^2=1 to both sides to complete the square.

Add 1 to both sides.

x2−2x+1=7+1

x2−2x+1=8

Step 3: Factor left side.

(x−1)2=8

Step 4: Take square root.

x−1=±√8

Step 5: Add 1 to both sides.

x−1+1=1±√8

x=1±√8

x=1+2√2 or x=1−2√2
