Answer:
Step-by-step explanation:
The linear equation in standard form is written in the form :
ax + by = c
Therefore : 12x = -9y + 7 in standard form will be :
12x + 9y = 7
Answer:
2.44 miles
Step-by-step explanation:
Give the following :
Average miles to school = 12 miles per hour
Average Miles from school = 15 miles per hour
Total ride time : ( time to school + time from school) = 22 minutes = (22/60) = 0.3667
Recall:
Speed = distance / Time
Time = distance / speed
Let distance = d
For the scenario described :
d/12 + d/15 = 0.3667
(5d + 4d) / 60 = 0.3667
5d + 4d = 22
9d = 22
d = 22/9
d = 2.44 miles
It already is in simplest form because the numerator and denonimator don't have a common factor to then divide them by.
Answer:
Step-by-step explanation:
The price per pizza is $8.00 with additional toppings priced at $1.00 each.
If x represents the number of additional toppings, then the prizza price is
p(x) = $8.00 = ($1.00/topping)x, where 0 ≤ x < ∞
