Answer:
Statistics
Step-by-step explanation:
Statistics is the science of collecting and analysing numerical data in large quantities from a sample.
Answer:
make the numberline 800 to 0 and do bunny hop to a different part of the number line to show subtraction.
Step-by-step explanation:
When it says "the subject", it only means you need to isolate the x, or solve for x. To do that, we have to get the x by itself. But how can we do that? We'll have to get rid of that pesky -5. Well, what can we do to -5 to get to 0? Of course -- Add 5!
b=x-5
+5
But whatever we do to one side of the equation, we have to do to the other.
b=x-5
+5 +5
We're left with b+5=x. There's your answer!

Answer:
(9, 6)
Step-by-step explanation:
add equations together: (x + y = 15) + (x - y = 3) --> x + x + y - y = 15 + 3 --> 2x = 18
isolate the variable: 2x/2 = 18/2 --> x = 9, so the x-coordinate is 9
substitute 9 in x's place in one of the equations: 9 + y = 15
solve for y: y = 15 - 9 --> y = 6, so the y-coordinate is 6
combine x and y coordinates together: (9, 6)
Answer:
The value of 7w - 8 is -22
Step-by-step explanation:
Let us solve the question
∵ -4w - 5 = 3
→ Move -5 from the left side to the right side by adding both sides by 5
∴ -4w - 5 + 5 = 3 + 5
∴ -4w = 8
→ Divide both sides by -4
∵ 
= 
∴ w = -2
→ Now let us find the value of the given expression
∵ The given expression is 7w - 8
→ Substitute w by -2 to gets its value
∴ 7w - 8 = 7(-2) - 8
∴ 7w - 8 = -14 - 8
∴ 7w - 8 = -22
∴ The value of 7w - 8 is -22
