Answer:
x = 6, y = -5.
Step-by-step explanation:
6x + 8y = -4
-6x - 10y = 14 Adding will eliminate the terms in x:
0 - 2y = 10
y = 10/-2 = -5,
Plug this into the second equation:
-6x - 10(-5) = 14
-6x = 14 - 50 = -36
x = -36/-6
x = 6.
Answer:8 kids per chaperon
Step-by-step explanation:
2/3 of a minute is longer than 1/3 of a minute
Firs month A
Second month 3A
Third month 3*3A = A (3^2)
Fourth month A(3^3)
Fith month A (3^4)
nth month A (3 ^ (n-1) )
That is an exponential model, because the variable (time, n) is the exponent of the formula.
After 1st year the value of the bike is 35% less, worth 65% of the original price: 0.65*600 = 390
2nd year 65% of 390
.65*390 = 253.5
