Answer:
5x +20
Step-by-step explanation:
For starters, you should start by finding somewhere to go off of. For instance, I started with 5 pecks of whortleberries and 4 pecks of huckleberries. This game me $69 of whortleberries and $20 of huckleberries, $89 in total. This tells me I need to go up. By going steadily upwards, I'll eventually settle on 8 whortleberry pecks and 1 huckleberry peck. This is $104 and $5, which, when added together, equals $109.
Answer: 8 Whortleberry Pecks, 1 Huckleberry Peck
Answer:
2 minutes
Step-by-step explanation:
You can make an equation to model the question.
y=60 initial starting value,
y=(750-720)x, plug in 60 for y,
60=30x, x = 2 minutes
(4x³ + 9xy + 8y) - (3x³ + 5xy - 8y) =
= 4x³ + 9xy + 8y - 3x³ - 5xy + 8y =
= 4x³ - 3x³ + 9xy - 5xy + 8y + 8y =
= x³ + 4xy + 16y ← the end answer
