Answer:
x=7
Step-by-step explanation:
x+4 + 2x1+3x-2 =45
6x+3 =45
6x=42
x=7
7+4 = 11
14+1=15
21-2=19
11+15+19 = 45

Answer:
1. 2.9
2. 51 inches
3. (if you can send a picture of the question, I can tell you an answer.
Step-by-step explanation:
for number 1:
You have to add the scores on the left and divide it by the total. What I did was multiply each number on the right with it's pair and added it up. I got 111. Afterwards, I totalled the number of students (I got 38) and divided the scores by the number of students to get 2.9.
for number 2:
You do the same thing as number one but instead of multiplying pairs, you add the heights. I got 255 and then divided it by 5 total heights. I got 51 inches.
for number 3: I didn't get the graph to tell you the answer but I can tell you what everything means.
Symmetric means that both sides of the graph are equal and if you fold the graph in half horizontally, you should get the same shape.
Gaps are where you see blanks in the graph where the data gets cut off and then has stats again.
Cluster is when a huge amount of data is gathered in one area.
Peak is where the data (x-axis) reaches it's highest point (highest y-axis point).
Good luck and please give me Brainliest if you liked my answer!
The boxes weigh 12 pounds and 20 pounds respectfully. We found this by setting up and solving an equation based on the problem's parameters.
Let's assume the lighter box weighs 'x' pounds, this makes the heavier box weigh 'x+8' pounds. According to the problem, the total weight of both boxes that the mail truck picks up from the post office is 32 pounds. So, we can set up the following equation: x + (x+8) = 32. Solving this equation we get 2x = 24, which means x = 12. So, one box weighs 12 pounds and the other box, which is 8 pounds heavier, weighs 20 pounds.
