Step-by-step explanation:
Problem 10:
Step One: Write the expression
When a problem says some number (in this case 17) more than a variable it almost always refers to addition. So we know that the expression's operation is addition. We are adding 17 to our variable, n. It should look like this:
n + 17
Step Two: Replace n with a Number
Pick your favorite number and replace n with that number. For simplicity's sake, I will choose the number 2. So n + 17 becomes:
17 + 2
Notice how n has been replaced with our number. Remember n could be any number, but I chose 2.
Step Three: Simplify the expression.
17 + 2 becomes 19
Problem 11:
Step One: Write the Expression
The first part of our expression is: g =
G represents the total cost of Paresh's day at the bowling alley, including all 5 games and shoe rental.
We know that to rent shoes, it cost Paresh 4 dollars. That becomes the second part of our expression. So now we have:
g = + 4
We also know that he played 5 games of bowling, but we don't know how much Paresh paid per game. So to represent the cost of each individual game, we will use the variable x. He played 5 games, so the third and final part of our expression is 5x. So our final result is:
g = 5x + 4
Answer:
A. 22.5
Step-by-step explanation:
Total balls in bag(sample space)=30
Red balls=4
Green=3
White=6
Yellow=7
Blue=10
event P(E) = (Number of favorable outcomes) ÷ (Sample space).
So p(red)=no red balls/total balls in the marble
P(red)=4/30=2/15
P(blue)=10/30=1/3
P(white)=6/30=1/5
P(yellow)=7/30
P(green)=3/30=1/10
Answer:
6
Step-by-step explanation:
25-7=18 18/3= 6.
6x3= 18 18+7= 25
THE ANSWER IS 6
