1 ) 3 t ( t + 2 ) - 3 t² =
= 3 t² + 6 t - 3 t² = 6 t = 6 · 19 = 114
2 ) - ( 3 a - 2 b ) - 3 ( - a- b ) =
= - 3 a + 2 b + 3 a + 3 b = 5 b
Y = -x + 3
y = 3/2x - 2
-x + 3 = 3/2x - 2....multiply everything by 2 to get rid of the fraction
-2x + 6 = 3x - 4
-2x - 3x = -4 - 6
-5x = -10
x = -10/-5
x = 2
y = -x + 3
y = -2 + 3
y = 1
solution is (2,1)
Answer: 91 guests
Step-by-step explanation:
Given the available furniture legs to be 364, where each seat has 4 legs
We will divide 364 by 4 to get the number of available seats.
364/4 = 91 seats
If 91 seats are available and it is set at 1 seat per guest,
Number of guests will be 91 seats/1 = 91, therefore, 91 guests will be available.
