The sum of 5 consecutive even numbers is 100. What is the first number in this sequence?
gayaneshka [121]

Answer:

16

Step-by-step explanation:

Let's represent this with an equation, where x is the first number. The next number must be x+2, because it has to be even, not x+1, and the rest continue the same way:

x+(x+2)+(x+4)+(x+6)+(x+8) = 100

Solve for x.

5x+20 = 100

5x = 80

<u>x = 16</u>

wlad13 [49]

Answer: The quantity of the water received by each student = 3.75 liters.

Step-by-step explanation:

Given: Total water = 18.75 liters

Total students =5

If each student in the group used the same amount of water for their experiment, then the quantity of the water received by each student = \dfrac{\text{Total quantity}}{\text{Total students}}

=\dfrac{18.75}{5}\\\\=3.75\ liters

The quantity of the water received by each student = 3.75 liters.

What is the slope of the line given (1,1) and (0,0)
yaroslaw [1]

The slope of the line passing the points (1, 1) and (0, 0) is 1

<h3>Slope of a line</h3>

The formula for calculating the slope of a line is expressed as

Slope = y2-y1/x2-x1

Given the coordinate points (1, 1) and (0, 0)

Substitute the given coordinate points

Slope = 0-1/0-1

Slope = -1/-1

Slope =1

Hence the slope of the line passing the points (1, 1) and (0, 0) is 1
