change the 6 ito - 6 by turning to left side then you will have -3 -6 now you can add them (- + -) is + so you can add them the sign of 6 is greater so the answer is -9

p = - 9

The 6 turns into - 6. Take - 3 and subtract it by - 6 and you will get - 9 as your answer.

Answer: An independent variable is exactly what it sounds like. It is a variable that stands alone and isn't changed by the other variables you are trying to measure. For example, someone's age might be an independent variable.

What is the measure of ∠KMN?
A. 29 degrees
B. 66 degrees
C. 53 degrees
D. 89 degrees

Answers

Answer:

  ∠KMN = 66°

Step-by-step explanation:

In ΔKMN,

∠MKN + ∠KNM + ∠KMN = 180       {Angle sum property of triangle}

39 + 75 + ∠KMN = 180

       114 + ∠KMN = 180

               ∠KMN = 180 - 114

           ∠KMN = 66°

Answer:

B) 66

Step-by-step explanation:

75+39=114

180-114=66

okay so we know that a circle is 360°

the one angle is 135 degrees and to find the other one we can just subtract 360 - 135

the other angle is 225°



we can set it up as:

12 yd x
——— = ——-
225 135


to find x, cross multiply 135 and 12 which gives you 1,620
1,620 / 225 = 7.2

the other angle is 7.2 yards!

Answer:

the answer is $102.20 because first lots are 8 of the and second lot are 7 of them,so 7×14.60=102.20

Answer:

Question 2: $102.20 collected second day

Question 1: x[tex]\leq[/tex]-5

Step-by-step explanation:

Question 2:

We know that there are 15 members total.  The first day 8 members paid and the remaining paid on the second day.  To find the second day total just subtract first day from total members and that leaves the number who paid on second day.

15-8=7

So now we know 8 paid on 1st day and 7 on 2nd day.  To find the total paid on either day just multiply cost of dues by number who paid that day.

14.60*7=102.2

Question 1:

First let's make an equation with info from picture...

In first box there are 4 of the rectangles and the Key tells us they represent x.  We also have 12 white squares the Key tells us represents 1 each.  So first box is...

4x+12

Second box has 8 shaded squares that Key tells us represents -1 each.  So second box is...

-8
