To convert, divide each tire's weight by 453.592 grams per pound:
800 grams ÷ 453.592 = 1.76 pounds
700 grams ÷ 453.592 = 1.54 pounds
To achieve a positive profit p(x)>0, we start with:

Next, we solve for x:

The parameters are:
a = -2
b = 7
c = -3
We will apply the quadratic formula:

This yields two results—one a fraction, the other a whole number. We focus on the whole number since the muffins sold must be a complete unit. Thus we conclude:
x>3
2.8y + 6 + 0.2y = 5y – 14
Start by simplifying the left side:
3y + 6 = 5y - 14
Next, deduct 3y from both sides:
6 = 2y - 14
Add 14 to both sides:
2y = 20
Now, divide by 2:
y = 20 / 2
y = 10
Answer:
1/5
Step-by-step explanation:
Amir and Tamara each consumed 2/5 of the candy bar.
The total consumed is 2/5 + 2/5 = 4/5.
Since 4/5 of the candy bar has been eaten, 1/5 remains.
This is because 5/5 minus 4/5 equals 1/5.
(Note that 5/5 represents a whole candy bar).
The telescope’s cost is $91
4.55 divided by 5% (0.05) equals 91.
