The answer to the above math expression is . See the computation below.

<h3>What is the calculation justifying the above?</h3>

First we solve for the numerator. The numerator is:

7√2 - 2√16

Where:

7√2 = 9.89949493661; and

2√16 = 8

Hence,

7√2 - 2√16 = 1.89949493661

Next we solve for the denominator. This is given as:

3√8=8.48528137424

Hence,

(7√2 - 2√16)/3√8 = 1.89949493661/8.48528137424

= 0.22385762508

$\approx$ 0.224

A n =−1+3(n−1) an=−1+3(n−1) what is the 55 term in the sequence

Sindrei [870]

ANSWER

$a_{55}=161$

EXPLANATION

The general term for the sequence is

$a_n=-1+3(n-1)$

To find the 55th term, we have to substitute
$n = 55$
in to the general term and simplify.

This implies that,

$a_{55}=-1+3(55-1)$

$a_{55}=-1+3(54)$

$a_{55}=-1+162$

$a_{55}=161$

Therefore the 55th term is 161.

Strike441 [17]

Step-by-step explanation:

I have two step

step 1

32+b=54

32+9=54

41=54

you divide both side by 41 and the answer is 1 and 1

step two

32+b=54

b=54-32

9=22

you divide both side by 9 and the answer is 2,44

What is the probability of randomly picking a girl without brown hair

ikadub [295]

6 girls have brown hair, and you want to know the probability of finding one without brown hair, so you take the population and subtract brown hair, or 22. You have a 22/28 chance of picking a girl without brown hair, simplified to 11/14.

Solving systems by substitutions

svp [43]

Let's take two different equations.

4x+2y=8
7x+3y=-10
(I just came up with these on the spot, so the answers might be strange but i should be able to explain nevertheless)
First, let's solve the first equation for "y".
4x+2y=8
-4x -4x
2y=8-4x
/2
y=4-2x
Now that we have "y", let's plug it into the second equation.
7x+3(4-2x)=-10
7x+12-6x=-10
x+12=-10
-12 -12
x=-22
Alright, now we have "x" definitively, let's plug it in to find "y".
4(-22)+2y=8
-88+2y=8
+88 +88
2y=96
/2
y=48
So from this example you can see. You solve one variable in terms of another (solve y as being 4-2x), plug it into the second equation to find one variable's value, then plug that variable's value back in again later to get the first variable's value.
