Answer:
8 is your answer for x
Step-by-step explanation:
Note that this is an equilateral triangle, meaning that all of the sides are congruent. This means that all the angel measurements are congruent.
First, divide 180 with 3 (3 because there are 3 angles)
180/3 = 60
Each angle must equal 60. You are solving for x. Set the expression with x as the variable equal to 60
7x + 4 = 60
Isolate the x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. First, subtract 4 from both sides.
7x + 4 (-4) = 60 (-4)
7x = 60 - 4
7x = 56
Next, divide 7 from both sides.
(7x)/7 = (56)/7
x = 56/7
x = 8
8 is your answer for x.

You have 18.6.
You need to find the smallest number that would round up to 18.6.
It is 18.55
Since the last digit is the hundredths place is a 5, to round to the nearest tenth, you drop the last 5 and the first five becomes 6 giving you 18.6.
Answer: 18.55
The weight of wrestler was 80 kg before the special diet
Step-by-step explanation:
Given function is:
![W=80+5.4t](https://tex.z-dn.net/?f=W%3D80%2B5.4t)
We can substitute the values of t to find the weight after t number of months
When we have to find the initial weight , t has to be put equal to zero
So,
![W = 80+5.4t\\t = 0\\W = 80 + 5.4(0)\\W = 80+0\\W = 80](https://tex.z-dn.net/?f=W%20%3D%2080%2B5.4t%5C%5Ct%20%3D%200%5C%5CW%20%3D%2080%20%2B%205.4%280%29%5C%5CW%20%3D%2080%2B0%5C%5CW%20%3D%2080)
Hence,
The weight of wrestler was 80 kg before the special diet

Answer:
Function with smallest zero is:
f(x); (2, 0).
Step-by-step explanation:
f(x):
2x2 − 14x + 20 = 0
x^2 - 7x + 10 = 0
(x - 5)(x - 2) = 0
So the zeroes are (2, 0) and (5, 0)
g(x):
From the table:
when g(x) = 0, x =19 so its zero is (19, 0).
