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.

( 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
two times the sum of a number and 22 is atleast -28

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.
