Answer:
x 0.4
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
The answer is 5 people.
Step-by-step explanation:
$9.50 times 5 people equals $47.50, plus the fee of $1.25, equals $48.75. With only $1.25 left over after that, you could not afford to pay for any more tickets for others to see the movie.

Answer:
57.1
Step-by-step explanation:
Using cosine rule
Cos¤ = 21/25
Cos¤ = 0.84
¤ = 57.12 appropriately 57.1
2(a+3) + 3(2a-1)
First, let's use the distributive property to expand 2(a+3):
2(a+3) = 2*a + 2*3 = 2a + 6
Let's use the distributive property now to expand 3(2a-1):
3(2a - 1) = 3*2a - 3*1 = 6a - 3
So 2(a+3) + 3(2a-1) = 2a + 6 + 6a - 3
Now you calculate variables between each others, and numbers between each others:
2a + 6 + 6a - 3 = 2a + 6a + 6 - 3 = 8a + 3
So the simplified form of 2(a+3) + 3(2a-1) is 8a + 3.

Answer:
The original price of an item less a discount of 20% is 0.8p where p is the original price
Step-by-step explanation:
Here, we want to write an algebraic expression that represents the original price of an item less a discount of 20%
Let the original price of the item be p
The meaning of the ‘less’ is that we are subtracting 20% of the price from the original price ;
So 20% of the price will be 20/100 * p = 20p/100 = p/5 = 0.2p
So let’s take this away from the original price p
That will be;
p - 0.2p = p(1-0.2) = 0.8p
