Let's break this up:
let x = the number
"when I triple my number" is the same as
3x
"and add five" is the same as
+5
We combine it to get
3x+5
"I get twenty-six"
=26
combine to get
3x+5=26
Now we just solve:
subtract 5 from both sides to get
3x=21
divide by 3 to get
x=7
Answer:
45°
Step-by-step explanation:
I think you meant m<ACB, and from what I see here, I took half of 90°, which is 45°.
Answer: z = 7

total: 13.39
13.39 rounded to 13.40 is the sum of the length of string after 10 throws.
Based on the table: I generated the formula:
f(x) = 3 </span></span></span></span>×<span><span><span><span> 0.80</span></span></span></span>ˣ
where the exponent x represents the number of throws.
