45L + 30D = 360 ...reduce by dividing by 15 = 3L + 2D = 24
65L + 35D = 470...reduce by dividing by 5 = 13L + 7D = 94
3L + 2D = 24......multiply by 7
13L + 7D = 94...multiply by -2
------------------
21L + 14D = 168 (result of multiplying by 7)
-26L - 14D = - 188 (result of multiplying by -2)
-----------------add
-5L = - 20
L = -20/-5
L = 4
3L + 2D = 24
3(4) + 2D = 24
12 + 2D = 24
2D = 24 - 12
2D = 12
D = 12/2
D = 6
so the loaves of bread (L) cost $ 4 per loaf and the buns (D) cost $ 6 per dozen
The second one because domain refers to x, and since at (-3,-4) the point is hollow, the sign should be < without the line under it
Person = 1 head and 2 legs
horse = 1 head and 4 legs
p +h = 74
p = 74-h
2p +4h = 196
2(74-h) +4h = 196
148-2h +4h = 196
148 +2h = 196
2h = 48
h = 48/2 = 24
24 horses
50 people
answer is B
Answer:
50 small trees
Step-by-step explanation:
