Every hour is 15$, thus you can do x for hours, and the function would be 15x

Alright, so in the table, x is the input, or the hours worked. The pay, or the output, is our y value.

This shows for every 2 hours worked, we get 15 dollars.

Let's write it out

2x=y

y=15

x=1 hour

The x is hours and the y is dollars.

A function rule is written as a ratio.

So we will compare hours to minutes.

Our function is 2:15

Answer: 2:15

Julia is five years older than her sister Babs, and their ages add up to 31. How old is Babs?
Tresset [83]
<span>Julia is X+5

</span><span>x+x+5=31
</span>
Now we just solve the equation 

2x=31-5
x=26/2
x=13 years old (Babs' age)

and we know that julia is 5 years older this gives us the conclusion that. 

13+18=31

Given the equation y = 3x − 4, what is the value of x when y = 5? A) 3 B) 6 C) 9 D) 12
Dmitrij [34]

Answer:

A. 3

Step-by-step explanation:

The answer would be A because 3 times 3 is 9 and 9-4=5 which is the value o f y. 3x-4=5

add 4 to both sides: 3x=5+4

simplify: 5+4=9

divide both sides by 3:  x= 9/3

simplify 9/3 to 3:

x= 3

hope this helps!!

Help anyone? please?
ValentinkaMS [17]

Answer:

x=11.2

Step-by-step explanation:

Set up a proportion:

x+11/36 = 37/60

Cross multiply:

1332=60(x+11)

Distribute:

1332=60x+660

Subtract 660 from 1332

672=60x

Divide:

x=11.2

I'm not sure if this is the correct answer but I hope this helps! :)

Correct me if I'm wrong!

Which expression is equivalent to -1/4 x + 1/2?
Anna71 [15]
The expression is given by:

-\frac{1}{4}x+ \frac{1}{2}

So we need to find an equivalent equation for this problem. Then, we will apply some mathematical rules:

Extracting the common factor 1/4, then:

\frac{1}{4}(-x+2})

Or extracting the common factor -1/4, then:

-\frac{1}{4}(x-2})

So, comparing these solutions with the answers about, there is no any answer that matches.
