7 0

Answer: 21

Step-by-step explanation:

Let the number be x , then ;

\frac{5}{7} of x = 15

that is :

\frac{5x}{7}=15

5x = 15(7)

5x = 105

divide through by 5

x = 21

E line plot below shows the amount of water Rickayla drinks in 10 days. Part a: how many cups of water did Rickayla drink in 10
Levart [38]

Answer:

Total = 23\frac{1}{4} cups

Step-by-step explanation:

Incomplete question.

See attachment for line plot

Required

Total cups drank in 10 days

The number of x at the top of each dataset represent the frequency (i.e. number of cups) drank on that day.

To get the total, we simply multiply this frequency by the accompanying dataset.

So, we have:

Total = 2 * 1\frac{1}{2} + 1 * 1\frac{3}{4} + 2 * 2 + 2 * 2\frac{3}{4} + 3 * 3

Express fractions as improper fraction

Total = 2 * \frac{3}{2} + 1 * \frac{7}{4} + 2 * 2 + 2 * \frac{11}{4} + 3 * 3

Evaluate each product

Total = 3 + \frac{7}{4} + 4 + \frac{11}{2} + 9

Take LCM

Total = \frac{12+ 7+16+22+36}{4}

Total = \frac{93}{4}

Total = 23\frac{1}{4}

Heeeeelppp please, :) please
lara [203]

Answer:

7/6

Step-by-step explanation:

In order to find slope when you have two ordered pairs, you use this equation: (y2-y1)/(x2-x1)

In this case, when you plug them in, you get (49-7)/(42-6), which is 42/36, which is 7/6.

Hope this helped :)

Darina [25.2K]

Answer:

0

Step-by-step explanation:

-7+1+ -1 * -6

Using PEMDAS, we multiply and divide first

-1*-6 = 6

Then we add and subtract from left to right

-7+1+ 6

-6+6 =0
