55,516 ÷ ? = 5.5516
likoan [24]

Answer:

55,516 ÷ ? = 5.5516 - ? = 1,000

5,551,600 ÷ 10,000 = ? - ? = 555.16

? ÷ 10,000 = 55,516 - ? = 5.5516

55,516,000,000 ÷ 10,000 = ? - ? = 5551600

Step-by-step explanation:

Hope this helps

Determine the expression you can substitute for y in to solve the system below.
FromTheMoon [43]

Answer:

Step-by-step explanation:

given are the two following linear equations:

                       f(x)  =  y  = 1 +  .5x

                       f(x)  =  y  = 11 -  2x

Graph the first equation by finding two data points.  By setting first x and then y equal to zero it is possible to find the y intercept on the vertical axis and the x intercept on the horizontal axis.

           If x = 0, then  f(0)  =  1  + .5(0)  =  1

           If y = 0, then  f(x)  =  0  = 1  +  .5x

                                               -.5x  =  1

                                                    x  =  -2

           The resulting data points are  (0,1)  and  (-2,0)

Graph the second  equation by finding two data points.  By setting first x and then y equal to zero it is possible to find the y intercept on the vertical axis and the x intercept on the horizontal axis.

           If x = 0, then  f(0)  =  11  - 2(0)  =  11

           If y = 0, then  f(x)  =  0  = 11  -  2x

                                               2x  =  11

                                                    x  =  5.5

           The resulting data points are  (0,11)  and  (5.5,0)

At the point of intersection of the two equations x and y have the same values.  From the graph these values can be read as x = 4 and y = 3.

Find the first four terms of the given sequence tn = (-1)n(n).
Leno4ka [110]
First we rewrite the expression correctly:
 tn = ((-1) ^ n) * (n)
 We now look for each of the terms:
 t1 = ((-1) ^ 1) * (1) = - 1
 t2 = ((-1) ^ 2) * (2) = 2
 t3 = ((-1) ^ 3) * (3) = - 3
 t4 = ((-1) ^ 4) * (4) = 4
 The first four terms of the sequence are then:
 -1, 2, -3, 4
 Answer:
 
B.
 
-1, 2, -3, 4

Every 5 1/2 cups of flour weighs 1 9/16 pounds. Use a unit rate to show how you could determine if there are more than or less t
chubhunter [2.5K]
1 9/16 pounds /  5 1/2 cups will tell you the unit rate of 25/88 pound per 1 cup.  So if you take 25/88 times 35 cups, you will find that it is 9 83/88 pounds.  This is less than a 10-pound bag of flour.
