Mama L [17]

Answer:

X Company charges (0.2+0.01n)\times 10^2 \ cents more than Company Y

Step-by-step explanation:

Given:

Cost of X company = \$ 0.35+(\$0.05\times 1 \ minute)

Cost of Y Company =\$ 0.15+(\$0.04\times 1 \ minute)

for n minutes

Cost of X company for n minutes = \$ 0.35+(\$0.05\times n \ minute)

Cost of Y Company for n minutes =\$ 0.15+(\$0.04\times n \ minute)

Difference for n minutes we get by Subtracting Cost of Y Company for n minutes by Cost of X company for n minutes

Difference for n minutes = (\$ 0.2+\$ 0.01n)=(0.2+0.01n)\times 10^2 \ cents

X Company charges (0.2+0.01n)\times 10^2 \ cents more than Company Y

Simultaneous equations <br>5x + 3y= 31<br>2x + y = 12 <br><br>a. find for x​<br>b. find for y
Anna007 [38]

Answer:

x=5

y=2

Step-by-step explanation:

5x + 3y= 31

-6x - 3y = -36  (multiple  by -3)

 

-x=-5

x=5

2(5)+y=12   or         25 + 3y= 31

10+y=12                  3y=6

y=2                          y=2

The mean of 8 math quiz scores is 88. If the first seven scores are 85,70,92,85,91,100, and 88, what is the eighth quiz score? U
777dan777 [17]

Answer:

93

Step-by-step explanation:

The mean of a list of numbers is the sum of the numbers divided by the count of the numbers in the list.

In this case, representing the eighth score with x, the mean is (611+x)/8

Solving for the mean:

88=(611+x)/8

Multiply both sides by 8

8*88=611+x

704=611+x

704-611=x

x=93
