Your choices A and C are the same
but the decimal of 1/11 is 0.090909
so your answer would be 2.09
$40+$35=$75
75/100*8.75=6.5625
6.5625+75=81.5625
approximately equal to $81.56
2:3
it was originally 8:12, but it has to be simplified. 2/3 can also work as an answer.
Answer:
B and D
Step-by-step explanation:
Write as a quadratic
-2x² - 3x + 5 = 0
Factor
-2x² - 5x + 2x + 5 = 0
-x(2x + 5) + 1(2x + 5) = 0
(1 - x)(2x + 5) = 0
To make the equation 0, x is either 1 or -5/2.
Answer:
x=1 y=-5
Step-by-step explanation:
7(5x-2y=15) ---> 35x-14y=105
2(7x+7y=-28) --> + <u>14x+14y=-56</u>
49x=49 --->x=1
5(1)-2y=15 ---> 5-2y=15 ---> -2y=10 ---> y=-5
