Picture a number line. the starting point is 0. go forward 5 which brings u to 5 on the number line. then since he lost 7 go back 7 which brings u to -2. now to get back to 0 you need to go forward 2. which means that he must gain 2 in order to get back to the starting point.

the slope of a line is 3/2 and the line contains the points (5,9) and (3, a). what is the value of a?
vivado [14]
Y = mx + b
slope(m) = 3/2
(5,9)...x = 5 and y = 9
now we sub and find b, the y int
9 = 3/2(5) + b
9 = 15/2 + b
9 - 15/2 = b
18/2 - 15/2 = b
3/2 = b
so ur equation is : y = 3/2x + 3/2.........(3,a)....so x = 3

y = 3/2(3) + 3/2
y = 9/2 + 3/2
y = 12/2
y = 6

so ur missing value is 6...a (or y)  = 6

Because of the commutative property of multiplication 3/4X4=4X3/4 However these expressions can be calculated in different ways
elena55 [62]

Answer:

We obtain same product by both the methods.  

Step-by-step explanation:

We are given the following in the question:

Commutative property of multiplication:

\dfrac{3}{4}\times 4  =4\times \dfrac{3}{4}

Different ways to find the product:

1. First way

\dfrac{3}{4}\times 4\\\\=3\times \dfrac{4}{4}\\\\=3

2. Second way

\dfrac{3}{4}\times 4\\\\=\dfrac{12}{4}\\\\=3

We get the same product for both the calculations.

A muffin recipe, which yields 12 muffins, calls for 2/3 cup of milk for every 1 3/4 cups of flour. The same recipe calls for 1/4
djyliett [7]

Answer:

4\dfrac{3}{8} cups of flour

Step-by-step explanation:

A muffin recipe, which yields 12 muffins, calls for 2/3 cup of milk for every 1 3/4 cups of flour.

Then this recipe, which yields one muffin, calls for

\dfrac{2}{3}:12=\dfrac{2}{3}\cdot \dfrac{1}{12}=\dfrac{1}{18}

cup of milk for every

1\dfrac{3}{4}:12=\dfrac{7}{4}\cdot \dfrac{1}{12}=\dfrac{7}{48}

cups of flour.

Thus,

this recipe, which yields a batch of 30 muffins, calls for

\dfrac{1}{18}\cdot 30=\dfrac{5}{3}=1\dfrac{2}{3}

cups of milk for every

\dfrac{7}{48}\cdot 30=\dfrac{210}{48}=\dfrac{35}{8}=4\dfrac{3}{8}

cups of flour.
