Answer:
1
Step-by-step explanation:
12x+x+4=17
13x=17-4
13x=13
x=1
Answer:
3x+2y=15--------(1)
4x+2y=20--------(2)
then, 2y=15-3x------(3)
putting value of 2y in equation (2)
4x+15-3x=20
x=5
then after , putting value of x in eq(3)
y=(15-15)/2
y=0
3x^2 + 180x - (3x^2 - 160x + 300) = profit
3x^2 + 180x - 3x^2 + 160x - 300 = profit
340x - 300 = profit
so if 150 televisions are sold...x = 150
340(150) - 300 =
50,700 <==
Answer:
4
Step-by-step explanation:
Each box is 1 larger than the earlier one, so the boxes are 1, 2, 3, 4, and 5.
4 + 5 is the width across the bottom
2 + 3 is the width across the top (not counting h)
9 - 5 = 4, so h = 4
Answer:
X = 4/13
Y = - 5/13
Step-by-step explanation:
Since all of the equalities are true, the ordered pair is the solution of the system
