A football team is on the 40-yard line after four plays. On the first play they gained 15 yards. On the second play they lost 6 yards. They gained 3 yards on the third play and twice as many on the fourth play. On which yard line did the team begin?

Answers

Answer: 22 yard line

22 + 15 = 37

37 - 6 = 31

31 + 3 = 34

Twice as many is X2 usally so

3x2=6

34 + 6 = 40

Answer:

22-yard line

Step-by-step explanation:

1st play - 2nd play = 15-6 = 9 yards

3rd play - 4th play = 9 + 3 + 6 = 18 yards

18 yard movement

40-18 = 22- yard line

How to find mode:

To find mode what you do is find the number that is the most common in the number group. In this case, there was one 3, three 7's, one 2, one 4, one 5, one 1, and two 8's. And since there was the highest amount of 7's, 7 was the mode.

How to find median:

To find the median, you line the numbers up from smallest to greatest and find the middle number, since this was a even number, there were two center numbers which were 5 and 7, after finding those, you add 5 and 7 together and divide that by two. So the equation would be (5+7)÷2=6

How to find mean:

To find the mean, you add all of the numbers together then divide it by the amount of numbers there are. The equation would be: (3+7+2+4+7+5+7+1+8+8)÷10=5.2

How to find range:

To find the range you do the largest number minus the smallest number. In this case it would be 8-1=7.

Answer; 20 weeks

Explanation;
Given,5 cases containing 6 cartons
=boxes in each carton= 12 x 6= 72
= 72 boxes of sauce in each case
= sauces in all 5 cases= 72 x 5= 360
Therefore narrator uses 18 boxes of sauce each week
To find how many weeks it will last we divide 360 with 18 as 18 sauce boxes are used every week and total sauces are 360=

18/360= 20
Narrator uses the sauce boxes for 20 weeks.

Examine the linear graph. Determine the y-intercept and write the y-intercept in coordinate form. Then write the equation of the line in slope-intercept form.

Answers

Answer:

y-intercept: 100 (0, 100)

[tex]y=\frac{8}{7}x+100[/tex]

Step-by-step explanation:

The y-intercept is the point on a graph that crosses the y-axis, this line crosses the y-axis at 100.

slope-intercept form is: [tex]y=mx+b[/tex]

[tex]m=slope[/tex]

[tex]b=y-intercept[/tex]

This line has a slope of 8/7 and the y-intercept is 100 so the equation would be: [tex]y=\frac{8}{7}x+100[/tex]

y=8/3x+100 is the equation of the line in slope-intercept form.

What is Slope of Line?

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

From the given graph let us consider two points through which the line is passing.

(0, 100) and (42, 148)

Slope=148-100/42

=48/42=8/3

Now let us find the y intercept

100=8/3(0)+b

b=100

So slope intercept form is y=8/3x+100

Hence, y=8/3x+100 is the equation of the line in slope-intercept form.

Which equation has a solution of k = 6.5?
-3k = 19.5
-1 + k = 7.5
-7k = -45.5
-2 + k = -8.5

Answers

Answer:

-7k = -45.5

Explanation:

You can solve this by plugging in the “k” to the problems that are listed.
If you were to plug 6.5 in for all those problems, you’d get:

-3(6.5) = -19.5

-1 + 6.5 = 5.5

-7(6.5) = -45.5

-2 + 6.5 = 4.5

So, in this case, looking at the ones I answered and looking at the problems listed, the correct answer would have to be -7k = -45.5.
-7k=-8.5 since if you were to plug the number Back in (-7k(6.5)=7.5 the equation is correct
