Answer: 4 hours
Step-by-step explanation:
First, set up an equation. We know that Bob spent $30 on playing paintball so we use that as our 'answer.' We need to find how many hours Bob played so we need to use x, a variable to find it. We also add 16 because we need to account for the entry fee.
3.50x + 16 = 30
Secondly, solve for x. Move 16 across the equal sign(=). Every time you move across the =, you're going to want to change the sign (if it's addition or subtraction). Since it was +16 and we're moving it, it's now -16.
3.50x = 30 - 16
Calculate 30 - 16 = 14.
Now we have
3.50 x = 14.
To calculate x, we're going to need to divide 3.50 from x. Since we multiplied by x we need to do the opposite across the =.
x = 14 / 3.50
x = 4
Bob spent 4 hours playing paintball.

3.50 (4) +16 = 30

A cup of dog food weighs 1 and 7/8 ounces. My dog eats 5 cups per day. How many ounces of dog food does he eat?
Answer:
9 3/8 ounces of dog food
Step-by-step explanation:
1 cup = 1 7/8 ounces
1 7/8 + 1 7/8 = 2 14/8 = 3 6/8
3 6/8 + 1 7/8 = 4 13/8 = 5 5/8
5 5/8 + 1 7/8 = 6 12/8 = 7 4/8
7 4/8 + 1 7/8 = 8 11/8 = 9 3/8

Answer:
Expand the following expressions.
1. 5 (r +2)
= (5×r) + (5×2)
= 5r + 10
2. 6b (b-2a)
= (6b×b) - (6b×2a)
= 6b²-12ba
3. 8cd (c-2 +40)
= (8cd×c) - (8cd×2) + (8cd×40)
= 8c²d - 16cd + 320cd
= 8c²+ 304cd

There were 56 runners to start a race. In the first half of the race, h of them dropped out. In the second half of the race, z of the remaining runners dropped
out. How many runners finished the race?
Answer:
56-h-z runners
Step-by-step explanation:
The only number we're given is 56, so the only thing that we can do is create an expression
Answer:
56 - h - z
Step-by-step explanation:
-h - z is the number of people who dropped out at any time in the race.
56 is the total amount, and you put -h - z behind it.
Therefore, you get 56 - h - z.

The expression is written with parentheses and the signs will be 5 + 23 + 18 x (8 - 4) = 100.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
5 + 23 + 18 x (8 - 4) = 100
Simplify the expression, then we have
5 + 23 + 18 x (8 - 4) = 100
5 + 23 + 18 x 4 = 100
28 + 72 = 100
100 = 100
The expression is written with parentheses and the signs will be 5 + 23 + 18 x (8 - 4) = 100.
