Answer:
1. Proportional
2. Not proportional
3. Proportional
Step-by-step explanation:
Mike's proportion
Michael gave $1.32 tip for an order that cost $8.80
$1.32÷$8.80=0.15
Given
1. $2.22 for $14.80
$2.22÷$14.80 =0.15
It is proportional to Mike's tip
2. $1.86 for $10.50
$1.86÷$10.50=0.1771
It I not proportional to Mike's tip
3. $0.78 for $5.20
$0.78÷$5.20=0.15
It is proportional to Mike's tip
Therefore,
1. Proportional
2. Not proportional
3. Proportional
Answer:
3x (x² + x + 1)
You could write any trinomial like this
To find the missing value divide both sides by -7:
28/-7 = 4
The missing value is 4
-5y=10-2x
add 2x to both sides
2x-5y=10
