Answer:

m = 3

Step-by-step explanation:

5m - 12 = m

subtract 5m from both sides

5m - 5m - 12 = m - 5m

simplify

-12 = -4m

divide both sides by -4

-12 / -4 = -4m / 4

simplify

3 = m

hope this helps :)

Which relationship between x and y in the equation shows a proportional relationship

balandron [24]

Answer:

The equation y = 3x shows a proportional relationship between x and y

Step-by-step explanation:

The proportional relationship is represented graphically by a line passes through the origin point

The equation of the proportional relationship is y = m x

Let us solve the question

Substitute x by 0 to find the value of y, if y = 0, then the line represents this equation passes through the origin point, then the equation shows a proportional relationship

∵ y = 3x

∵ x = 0

∴ y = 3(0)

∴ y = 0

→ That means the line that represents the equation passes through

the origin point

∴ The equation y = 3x shows a proportional relationship between x and y

REN fine six peanuts, four raisins, 3 cranberries, and 5 chocolate chips in a handful of trail mix. For every 9 pieces in Ren's

tankabanditka [31]

Answer:

2 raisins.

Step-by-step explanation:

Let x represent total number of required ingredient.

We have been given that Ren finds 6 peanuts, 4 raisins, 3 cranberries, and 5 chocolate chips in a handful of trail mix. We are asked to find of which ingredient Ren will have 2 pieces for a total of 9 pieces.

First of all, we will find total number of ingredients by adding each ingredient as:

$\text{Total number of ingredients}=6+4+3+5$

$\text{Total number of ingredients}=18$

Now, we will use ratio to solve for our given problem as:

$\frac{\text{Required ingredient}}{\text{Total ingredient}}=\frac{2}{9}$

$\frac{x}{18}=\frac{2}{9}$

$\frac{x}{18}\cdot 18=\frac{2}{9}\cdot 18$

$x=\frac{2}{1}\cdot 2$

$x=4$

Since there are 4 raisins, therefore, for every 9 pieces in Ren's handful of trail mix there are 2 raisins.

Calculate the unit rate: write your answer as a decimal 1/2 mile in ever 1/3 hour

Alexandra [31]

Answer:

$unit \: rate = \frac{distance}{time}$

unit rate is similar to speed / velocity:

$unit \: rate = \frac{ (\frac{1}{2} )}{ (\frac{1}{3})} \\ \\ = \frac{1}{2} \div \frac{1}{3} \\ \\ = \frac{1}{2} \times \frac{3}{1} \\ \\ = > { \boxed{ \boxed{unit \: rate = \frac{3}{2} \: miles \: per \: hour}}}$
