You can solve this by substitution:
x + y = -6
y = -6-x
Substitute for y in xy = -7:-
x(-6 - x) = -7
-x^2 - 6x = -7
x^2 + 6x - 7 = 0
(x + 7)(x - 1) = 0
so x = -7, 1
To find the values of y plug these va;ues of x into the equation x + y = -6:-
when x = -7, y = -6 + 7 = 1
when x = 1, y = -6 - 1 = -7
so answer is x = -7 and y = 1
and x = 1 and y = -7
The tax accounted for $16.51 of the total $254.
6.5% of 254 is 16.51. This is found by multiplying 254 by .065.
Idk if this is the right way but u can divide like 10.3 times 3 =30.6 and if u divide 30.6 by 3 you get 10.6 so that's a simple way hope it helped
Answer:
Step-by-step explanation:
43,785 is not even so it is not divisible by 2
when we add its digits 4+3+7+8+5 = 27 and it is divisile by 3
43,785 ends with 5 so it is divisible by 5
43,785's sum of digits are 27 and it is divisible by 9
43,785 does not end with a zero so it is not divisible by 10
