it does appear to be a 2?
Step-by-step explanation:
<u>11 chairs at each table.</u> (157/14 = 11.214...)
<u>There will be 3 chairs left over.</u> (14x11 = 154 157-154 = 3)
4x + 5y - 3 = 0
4x + 5y = 3
3x - 7y - 13 = 0
3x - 7y = 13
4x + 5y = 3......multiply by 3
3x - 7y = 13....multiply by -4
---------------
12x + 15y = 9 (result of multiplying by 3)
-12x + 28y = - 52 (result of multiplying by 4)
---------------add
43y = -43
y = -43/43
y = -1
3x - 7y = 13
3x - 7(-1) = 13
3x + 7 = 13
3x = 13 - 7
3x = 6
x = 6/3
x = 2
so ur solution is : (2,-1) <==
Answer:
Step-by-step explanation:
10g=18.9-3.9
10g=15
g=15/10
g=1.5
So each grapefruit costs $1.50
(L+d)9=126 and the original length was 11ft so
(11+d)9=126
99+9d=126
9d=27
d=3
So he needs to extend the length by 3ft
