Answer:

The calculated value of m in 4+ 7m=5 is 1/7

Solution:

Given that the expression is 4 + 7m = 5

We have to find the value of "m" in this given expression.

Let us consider the given expression 4 + 7m = 5 --- equation 1

By moving "4" from left hand side to right hand side of equation we get,

7m = 5-4

On solving above expression by subtracting 4 from 5 we get 1

7m = 1

On moving 7 from left hand side to right hand side of equation we get,

$m = \frac{1}{7}$

Hence the value of m is $\frac{1}{7}$

First you would isolate (7m) by subtracting 4 from both sides:
4 + 7m - 4 = 5 - 4
This would leave you with:
7m = 1
Then you would isolate m by dividing both sides by 7:
7m/7 = 1/7
Your final answer:
m = 1/7

What does 5 over 100 =

Nuetrik [128]

You can identify that "5 over 100" can be written as a fraction. 5 will be the numerator and 100 will be the denominator:

$\frac{5}{100}$

To reduce this fraction, you need to divide the numerator and the denominator by the Greatest Common Factor (GCF) between them.

In this case, to find the GCF, you need to:

- Decompose the number into their Prime Factors:

$\begin{gathered} 5=5 \\ 100=2\cdot2\cdot5\cdot5=2^2\cdot5^2 \end{gathered}$

- Notice that 5 is a common factor. Then, you need to choose the one with the lowest exponent:

$GCF=5$

Therefore, by dividing the numerator and the denominator by 5, you get:

$=\frac{1}{20}$

Hence, the answer is:

$=\frac{1}{20}$

What is the equation of a line that passes through the point (8, 1) and is perpendicular to the line whose equation is y=−23x+5

elena-s [515]

Answer:

$y-1=\frac{1}{23} (x-8)$

Step-by-step explanation:

We can write the equation of a line in 3 different forms including slope intercept, point-slope, and standard depending on the information we have. We have a point (8,1) and a slope from the equation y=-23x+5. We will chose point-slope since we have a point and slope.

Point slope: $y-y_1=m(x-x_1)$

$m\neq -23$ in our new equation because it us perpendicular to it. This means we will need to change it into its negative reciprocal which is $m=\frac{1}{23}$ .
