Answer:
C=14
Step-by-step explanation:
To find the minimum value, graph each of the inequalities. After graphing each inequality, test a point and shade the region that satisfies the inequality. Once all inequalities have been shaded, find the region where they all overlap. The region will be bounded by intersection points. Test each of these points into C=x+3y. The least value for C is the minimum.
(14,0) (0,17.5) (3.08,3.64)
C=14+3(0) C=0+3(17.5) C=3.08 + 3(3.64)
C=14 C=52.5 C=14
Hello there,
Answer: C=14
The number of ants after 60 days is 240.
An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
The population of ants doubles every 20 days.
Current number of ants = 30
Now,
The number of ants after 20 days.
= 30 x 2
= 60
The number of ants after 40 days.
= 60 x 2
= 120
The number of ants after 60 days.
= 120 x 2
= 240
Thus,
The number of ants is 240.

Step-by-step explanation:
16x8=128 and if you double it and half it, it would still be 128. none of the answer choices equal 128.
Answer:
3x = 48
Step-by-step explanation:
To easily do this, we'll make the statement in mathematical form.
Let x represent the number of friends at Jack's wedding.
The equation would be:
3 * x = 50 - 2
3x = 48
x = 48 / 3
x = 16
Therefore, the equation to determine the number of friends (x) at Jack's party is expressed as:
3x = 48

Answer:
Mariana takes the two pills together after 18 hours.
Step-by-step explanation:
Mariana must take two pills; one every 6 hours and another every 9 hours.
She take two pills together. Let she takes the two pills together after t hours at the time when she take initially.
To find the time to take the two pills together, take the least common multiple of 6 and 9.
6 = 2 x 3
9 = 3 x 3
So, the least common multiple is 2 x 3 x 3 = 18
So, she takes the two pills together after 18 hours.
