UGH GEEZ PLEASE HELP

trapecia [35]

Answer:

$0.40

Step-by-step explanation:

1st week total: 12.99 + 10.50 + 9.89 + 6.90 + 7.58 = $47.86

5 days total so the mean of 1st week: 47.86 / 5 = $9.57

2nd week, 2 more in total of 1st week = $47.86 + $ 2 = $49.86

The mean of 2nd week: 49.86 / 5 = $9.97

$9.97 - $9.57 = $0.40

2nd week increased 40 cents or $0.40

Select the coordinate point that is a solution of equations. 2x+y=7; 3x-4y=5

grandymaker [24]

Answer:

D (3,1)

Step-by-step explanation:

solving simultaneous equations

Arrange equations

2x+y=7

3x-4y=5

make y side cancell by addition by multiplying by 4 and 1 as shown

4{2x+y=7}

1{3x-4y=5}

8x+4y=28

3x-4y=5

11x=33

x=33/11=3

substitute for x=3 in 3x-4y=5

9-4y=5

4=4y

y=1
