I didn’t understand how to solve this, i’d be happy if someone explained thank you

kolbaska11 [484]

Answer:

Option (E)

Step-by-step explanation:

$\frac{a}{b}=\frac{c}{d}=k$

$\frac{a}{b}=k$

$b=\frac{a}{k}$ ------(1)

$\frac{c}{d}=k$

$d=\frac{c}{k}$ -------(2)

Since, $\frac{6a+24}{md+6b}=k$

By substituting the values of b and d from equation (1) and (2),

$\frac{6a+24}{\frac{mc}{k}+\frac{6a}{k}}=k$

$\frac{k(6a+24)}{6a+mc}=k$

$\frac{6a+24}{6a+mc}=1$

6a + 24 = 6a + mc

mc = 24

m = $\frac{24}{c}$

Therefore, Option (E) will be the correct option.

For what values of the variables are the following expressions defined? 1. 5y+2 2. 18/y 3. 1/x+7 4. 2b/10−b Example: X>7

Serga [27]

Answer:

1. All real numbers

2. All real numbers except y = 0

3. All real numbers except x = -7

4. All real numbers except b = 10

Step-by-step explanation:

For any function to be defined at a particular value, it should not be approaching to a value $\infty$ or it should not give us the $\frac{0}{0}$ (zero by zero) form when the input is given to the function.

The value of function will depend on the denominator.

Now, let us consider the given functions one by one:

1. 5y+2

Here denominator is 1. So, it can not attain a value $\infty$ or $\frac{0}{0}$ (zero by zero) form

So, for all real numbers, the function is defined.

$2.\ \dfrac{18}{y}$

At y = 0, the value

$At\ y =0, \dfrac{18}{y} \rightarrow \infty$

So, the given function is defined for all real numbers except y = 0

$3.\ \dfrac{1}{x+7}$

Let us consider denominator:

x + 7 can be zero at a value x = -7

$At\ x =-7, \dfrac{1}{x+7} \rightarrow \infty$

So, the given function is defined for all real numbers except x = -7

$4.\ \dfrac{2b}{10-b}$

Let us consider denominator:

10-b can be zero at a value b = 10

$At\ b =10, \dfrac{2b}{10-b} \rightarrow \infty$

So, the given function is defined for all real numbers except b = 10

Estimate the result by rounding the numbers to the second decimal before performing the operation. Then also round your answer t

umka2103 [35]

Answer:

40615

Step-by-step explanation:

Note, rounding off decimals involves observing if the said decimal is up to the value of 5. If it is, then it can be rounded up, if not, its rounded off.

Since we need to round the numbers to the second decimal before performing the operation, we will have, 8123÷0.2

Note, 8123 has no decimal so we ignore

But 0.211 has a second decimal which is the first 1 so because it's not up to 5, we round it off to 0.

Hence we have 8123 ÷ 0.2= 40615.0

Since our answer has no decimal, we leave it like that.
