What is the difference in the size between 1/4 and 1 1/2

1 answer:

8 0

1 1/2 can be rewritten as 3/2
Difference means subtraction

So we do:
3/2-1/4
To get the same denominator, we can multiply the first fraction by 2
6/4-1/4

Then we subtract the numerators and leave the denominator
So the final answer is 5/4 of 1 1/4

Hope this helps

Stephanie is making beef for a party the recipe uses 1 1/2 teaspoons of pepper, 3 2/4 teaspoons of garlic powder 1/8 teaspoons o

Arisa [49]

Answer:

She will use:

3 tablespoons of pepper

7 tablespoons of garlic powder

$\frac{1}{4}$ tablespoon of thyme

8 tablespoons of onion powder

Explanation:

To double the amount, Stephanie will need to double the amount of each ingredient used. This means that she will multiply each amount by 2

Therefore:

New amount of any ingredient = old amount of that ingredient x 2

This means that:

New amount of pepper = $1\frac{1}{2}*2= 3$ tablespoons

New amount of garlic powder = $3\frac{2}{4}*2=7$ tablespoons

New amount of thyme = $\frac{1}{8}*2=\frac{1}{4}$ tablespoons

New amount of onion powder = $4*2=8$ tablespoons

Hope this helps :)

Write an equation of the line that passes through each pair of point y=mx+b

jarptica [38.1K]

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

Explanation

Step 1

find the slope

when yo know 2 points of a lines, P1 and P2, you can find the slope by using:

$\begin{gathered} \text{slope}=\frac{change\text{ in y}}{\text{change in x}}=\frac{y_2-y_1}{x_2-x_1} \\ \text{where} \\ P1(x_1,y_1) \\ P2(x_2,y_2) \end{gathered}$

then, let

P1(6,0)

P2(0,4)

replace

$\begin{gathered} \text{slope}=\frac{y_2-y_1}{x_2-x_1} \\ slope=\frac{4-0}{0-6}=\frac{4}{-6}=-\frac{2}{3} \end{gathered}$

Step 2

find the equation of the line,

$\begin{gathered} y-y_1=slope(x-x_1) \\ \text{replace} \\ y-0=-\frac{2}{3}(x-6) \\ y=-\frac{2}{3}x+\frac{12}{3} \\ y=-\frac{2}{3}x+4 \end{gathered}$

so , the equation of the lines is

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

where -2/3 is the slope, and 4 is the y-intercept

I hope this helps you
