M=5
Positive 5 because a negative divide by a negative is a positive
All you have to do is divide 45 and 9

Answer:X=5

Step-by-step explanation:-9m=-45

First divide both sides by 9. The 9 will cancel out and you'll be left with 5 because of -45 divided by -9.The reason on why its positive is because a negative divided by a negative cancels out and becomes positive.

natulia [17]

Answer:

2 2/3

Step-by-step explanation:

Make them into improper fractions first.

11/2 - 17-6

Then multiply 11/2 so that they have common denominators.

33/6 - 17/6

Then solve.

33/6 - 17/6 = 16/6

Then convert back into a mixed number.

What does the variable represent in the equation 6-8p=38

GalinKa [24]

Solving the equation $6-8p=38$ we get value of p = -4

Step-by-step explanation:

We need to find the value of p in the equation $6-8p=38$

Solving to find value of p:

$6-8p=38\\Adding\,\,-6\,\,on\,\,both\,\,sides:\\6-8p-6=38-6\\-8p=32\\Divide\,\,both\,\,sides\,\,by\,\,-8\\\frac{-8p}{-8}=\frac{32}{-8}\\p=-4$

So, solving the equation $6-8p=38$ we get value of p = -4

Choose a situation that could be described by the following ratios, and write a sentence to describe the ratio in the context of

a_sh-v [17]

Part A:

Given the ratio 1 : 2, we can describe this ratio with the following situation.

The number of green balls to orange balls in the bag is in the ratio of 1 : 2. For every green ball in the bag, there are 2 corresponding orange ball.

Part B:

Given the ratio 29 : 30, we can describe this ratio with the following situation.

The ratio of the amount of sugar used to the amount of salt used to prepare the sugar-salt solution is 29 : 30. For every teaspoons of sugar used in the solution, 30 teaspoons of salt needs to be used.

Part C:

Given the ratio 52 : 12, we can describe this ratio with the following situation.

The number of kilometers travelled by the car and the bicycle is in the ratio of 52 : 12. For every 52 kilometers travelled by the car, the bicycle travelled 12 kilometers.

Y = 3/5x + 1, 5y = 3x - 2, 10x - 6y = -4<br> is it perpendicular, parallel, neither

Ber [7]

Answer:

$y=\frac{3}{5} x+1$ and $5y=3x-2$ are parallel.

$10x-6y=-4$ is neither parallel nor perpendicular.

Step-by-step explanation:

First, you have to simplify each equation in terms of y.

$y=\frac{3}{5} x+1\\5y=3x-2\\10x-6y=-4$

Your first equation is already in terms of x, so simplify your second equation.

$5y=3x-2\\y=\frac{3}{5} x-\frac{2}{5}$

Now you can simplify your third equation.

$10x-6y=-4\\-6y=-10x-4\\y=\frac{5}{3} x+\frac{2}{3}$

These are your three equations in terms of y:

$y=\frac{3}{5} x+1\\\\y=\frac{3}{5} x-\frac{2}{5} \\\\y=\frac{5}{3} x+\frac{2}{3}$

Now, all you have to know is how to tell using your slope if a line is parallel or perpendicular to another.

Two parallel lines will have the exact same slope.

Two perpendicular lines will have slopes which are opposite reciprocals. For example, a line with a slope of 2 is perpendicular to a line with a slope of $-\frac{1}{2}$ , as they have opposite signs and are reciprocal (2/1 versus 1/2) to each other.

Your first two equations have the same slope and are therefore parallel.

Your third equation is a reciprocal, but it is not opposite, and is therefore not parallel nor perpendicular.
