Answer:
AM = 900
CI = 500
I have to be honest, this is the most ridiculously worded question of this type that I have ever seen... ask you teacher, why it was so important to force you to solve it using only one variable?
Step-by-step explanation:
(AM) + (1400-AM) = 1400
2(AM) + 3(1400 - AM) = 3300
2AM + 4200 -3AM = 3300
-AM = -900
AM = 900
CI = 500
Answer:
-11xy
Step-by-step explanation:
Subtracting a negative means adding.
-14xy - (-3xy) = -14xy + 3xy = -11xy
Answer:
d = 25
Step-by-step explanation:
Perhaps you want to solve for d:
(0.3d -1.5)/(3 1/3) = 0.84/(7/15)
Change the division by a fraction to multiplication by its inverse.
(0.3d -1.5)·(3/10) = (0.84)·(15/7)
0.09d -0.45 = 1.8 . . . . . . . . . . . . simplify
d - 5 = 20 . . . . . . . . . . . . . . . . . . divide by 0.09
d = 25 . . . . . . . . . . . . . . . . . . . . . add 5

Grouping symbols help show what is being divided by what. Especially where mixed numbers are involved, parentheses help show that the number 3 1/3 is not supposed to be interpreted as the product of 3 and 1/3.
The original price I believe would be $349.44
Answer:
because there is 180 degrees in a line. if 105 degrees is taken away from the line. then (180 - 105) is 75 degrees.
