Answer: C) =

Step-by-step explanation: You can convert -14/4 from a fraction into a decimal. Take the denominator, 4, how many times does it go into the numerator, 14? 4 goes into 14 exactly 3.5 times. So, that means if the fraction was -14/4, you need to take that negative sign and put it in front of your decimal. Once you do that, you see that both the first and second number turn out to be the same number, -3.5. Therefore, your answer is C, as the numbers are equal to one another.

How do the constant of proportionality and slope relate to the unit rate

Pepsi [2]

Answer:

When a relationship is proportional, all y over x ratios simplify to the slope of the line which is the constant of proportionality or the unit rate, with one as a denominator. Example: Consider the equation y = 60x. The slope is 60. The rate of change is 60 units for every one unit.

Igoryamba

Answer:

Martin is 40 and Ada is 14

Step-by-step explanation:

Martin's age = m
Ada's age = a

Martin is two years younger than three times his daughter Ada’s age:

m = 3a - 2

The sum of their ages is 54:

m + a = 54

Solving this equation for m:

m = 54 - a

Eliminate m:

3a - 2 = 54 - a

Solve for a:

3a + a = 54 + 2
4a = 56
a = 56/4
a = 14

Find m:

m = 54 - 14 = 40

Martin is 40 and Ada is 14

Write a situation that describes the inequality: 12x – 14 < 200

photoshop1234 [79]

For this case we must write a situation for the following inequality:

$12x-14$

Andres needs less than $200 to go on vacation. It is known that in his work he earns $12 per hour, he must also pay a debt of $14. We want to know how many days he gets less than $200. Assuming Andres works 8 hours a day.

x: Variable that represents the number of hours Andres works

$12x-14$

Thus, Andres must work less than 17.83 hours for his trip.

Therefore, it requires three work days.

Answer:

$x$
