<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Independent variables represent function inputs that do not depend on other values, while dependent variables represent function outputs that depends on other values.

1 dollar = 5.43 Brazilians real

137 Brazilian real = 137/5.43

= $25.230

Hence, The cost of the jersey is $25.230

Find the inverse of the matrix , if it exists

Montano1993 [528]

Answer:

So, option A is correct.

Step-by-step explanation:

To find the inverse of the matrix, the formula is:

$A^{-1} = 1/|A| * Adj A$

Inverse of the matrix exists if |A| does not equal to 0

|A| = 7 * 9 -( -2 * -10)

|A| = 63 - 20

|A| = 43

AS |A| ≠ 0

so inverse exist.

now finding Adj A

$Adj A$ = $\left[\begin{array}{cc}9&2\\10&7\end{array}\right]$

$\left[\begin{array}{cc}9/43&2/43\\10/43&7/43\end{array}\right]$

So, option A is correct.

Write and evaluate the expression. Then, select the correct answer.

Law Incorporation [45]

Answer:

Step-by-step explanation: So we need to write and solve an equation to solve for m, which is 12. Simply plug in 12 for m in the equation.

Step 1: 2-x/4+10

Step 2: 2-12/4+10

Step 3: 2-3+10

Step 4: -1+10=9

Plug 12 in for x

12 divided by 4 is 3 and 2-3 is -1

-1 + 10 is 9 -1 + 10 is 9

4. If the ratio of 5 th term to 11th term of an A.P. is 5:2, then the value of term is 15th

yanalaym [24]

Answer: The value of 15th term is 0

Step-by-step explanation:

The nth-terms of an AP is written as $a+(n-1)d$

where,

a = first term

n = number of term

d = common difference

5th tem will be = $a+4d$

11th tem will be = $a+10d$

15th tem will be = $a+14d$

The given ratio between 5th and 11th term is 5 : 2

Taking the ratios:

$\Rightarrow \frac{a+4d}{a+10d}=\frac{5}{2}\\\\\Rightarrow 2a+8d=5a+50d\\\\\Rightarrow 3a+42d=0\\\\\Rightarrow 3(a+14d)=0\\\\\Rightarrow a+14d=0$

Hence, the value of 15th term is 0
