One month, ruby worked 8 hours more than isaac, and svetlana worked 4 times as many hours as ruby. together they worked 136 hour
Travka [436]

Let Issac work for x hours, and Ruby works 8 hours more than of Issac, so Ruby work for (x+8) hours.

And Svetlana worked four times of Ruby, therefore Svetlana worked for

4(x+8) hours

And total hours they worked together is 136. That is

x+x+8 + 4(x+8) = 136
\\
x+x+8 +4x+32=136
\\
6x+40 =136
\\
6x=96
\\
x =16 hours

So Issac worked for 16 hours, Ruby worked for 24 hours and Svetlana worked for 24 times 4 equals 96 hours .

Suppose you are going to graph the data in the table:
beks73 [17]

Answer:

A: x‒axis: minutes in increments of 5; y-axis: temperature in increments of 1

Step-by-step explanation:

Let the x-axis represent the minutes

Let the y-axis represent the temperature

Now, from the values given us in minutes, we can see that the difference between the values are Increasing at constant rate of 5 minutes .

Thus, minutes increment on the x-axis is 5.

Now,for the y-axis, the increment is not constant as it fluctuates.

Thus, we cannot use 5 like we did for the x-axis. Rather, the most appropriate temperature increment to be used on this y-axis for ease of locating the points will be 1.

Find the value of each variable and the measure of each labeled angle.<br> Explain your answer.
Mademuasel [1]

Answer:

(3x + 8) = 50

(5x - 20) = 50

(5x + 4y) = 130

Step-by-step explanation:

3x + 8 = 5x - 20

2x = 28

x = 14

5(14) + 4y + 5(14) - 20 = 180

y = 15
