Given:
Number of blue marbles, twice as many red marbles as blue, and 8 yellow marbles.
She has a total of 32 marbles.
To find:
The number of red marbles.
Solution:
Let number of blue marbles be x.
Then, number of red marbles = 2x
Number of yellow marbles = 8
Total number of marbles = 32
[tex]x+2x+8=32[/tex]
[tex]3x=32-8[/tex]
[tex]3x=24[/tex]
[tex]x=8[/tex]
Now,
Number of red marbles [tex]=2(8)=16[/tex]
Therefore, there are 16 red marbles.
Solve for x. Type only numerical values, do not type x=

Lili runs a small day care business, caring for 3 children.
• She earns $150 during regular work hours.
• She charges $0.50 for each minute parents are late.
The situation is represented by the equation below, where t is the total
dollar amount Lili earns each day and m is the total number of minutes
parents are late.
t=150 +0.5m
Which of the following solutions shows an amount of money Lili can
reasonably expect to earn each day?
Answer:
$150
Step-by-step explanation:
[tex]t=150 + 0.5m\\t=150+0.5*0\\t=150[/tex]
This is as we don't know how often the parents are late, nor if they are late. So we assume that the parents are never late.

( use elimination) on 3x+5y=12 and x-3y=4
Answer:
x=4 y=0
Step-by-step explanation:
3x+5y=12
-(x-3y=4)
3x+5y=12
3(-x+3y=-4)
3x+5y=12
-3x+9y=-12
14y=0
y=0
Then, substitute the y into the equation to find x
x-3(0)=4
x=4

The expression - 370 + 15z represents a submarine that began at a depth of 370 feet below sea leve
and ascended at a rate of 15 feet per minute. What was the depth of the submarine after 5 minutes?
Answer:
The depth of the submarine was 295 feet
Step-by-step explanation:
Function Modeling
The following expression models the depth of a submarine that began at -370 m and ascended at 15 ft/minute:
d = -370 + 15z
Where z is the time in minutes.
We are required to find the depth of the submarine at t=5 minutes. Substituting t=5 into the function model:
d = -370 + 15(5)
d = -370 + 75
d = -295 feet
The depth of the submarine was 295 feet

When solving for a quantity in a formula, what are the most important things to consider? What process do you follow in order to be sure that you've correctly solved for some quantity?
Answer:
Always follow PEMDAS.
Join all like terms.
Use inverse operations.
Always solve parentheses first (included in PEMDAS).
Make the variable alone, by itself, on one side of the equation.
Finally, substitute your answer in and see if it is correct.
