b)0.35
c)0.48
d)0.73
Answers
0.35 = 0.48 * P2
0.35/0.48 = P2
P2 = 0.7291666...,
d)0.73 is correct

Equation represent the number of times feliz can drive to or from work with the gas in his tank is
Step-by-step explanation:
The gas tank in felizs car is 5/6 full
When he drives to or from work he uses part of a full tank of gas =\frac{1}{12}
Let x be the number of times feliz can drive to or from work with the gas in his tank
So, He uses part of full tank of gas in x drives =
So, ATQ
x=10
The number of times feliz can drive to or from work with the gas in his tank is 10
Hence equation represent the number of times feliz can drive to or from work with the gas in his tank is

Answer:
(-2x ÷ 5) - (9/5 ÷ 5) = -2/5 * x - 9/25
Step-by-step explanation:
To solve the expression (2x - 2 1/5 - -4) ÷ -5, we need to follow the order of operations, also known as PEMDAS.
1. First, simplify the expression inside the parentheses (-2 1/5 - -4).
To subtract a negative number, we can change it to addition. So, (-2 1/5 - -4) becomes (-2 1/5 + 4).
Next, let's convert the mixed number -2 1/5 to an improper fraction.
-2 1/5 = -11/5
Now we can add the fractions: -11/5 + 4.
To add these fractions, we need a common denominator. The least common denominator for 5 and 1 is 5.
-11/5 + 4/1 = -11/5 + 20/5 = 9/5
Therefore, (-2 1/5 - -4) simplifies to 9/5.
2. Now, let's substitute the simplified expression back into the original expression: (2x + 9/5).
3. Finally, divide the expression by -5: (2x + 9/5) ÷ -5.
To divide by a negative number, we can multiply the expression by -1 and then divide by 5.
(2x + 9/5) ÷ -5 = (-1)(2x + 9/5) ÷ 5
Applying the distributive property, we get:
(-1)(2x + 9/5) ÷ 5 = (-2x - 9/5) ÷ 5
To divide by 5, we can multiply each term by 1/5:
(-2x - 9/5) ÷ 5 = (-2x ÷ 5) - (9/5 ÷ 5)
Simplifying further:
-2x ÷ 5 = -2/5 * x
9/5 ÷ 5 = 9/25
Therefore, the final answer is:
(-2x ÷ 5) - (9/5 ÷ 5) = -2/5 * x - 9/25
Please note that this is the simplified form of the expression, assuming that no specific value for x is given.

cost=total money
cost=number of tshirts times cost per tshirt
subsitute
m=27 times cost per shirt
to solve for cost per 1 shirt, divide both sides by 27
answer is 1 t-shirt costs
y = how much each t-shirt costs
m / 27 = y
because:
y x 27 = m
so the equation is:
>m/27 = y
