Angles along a straight line equal 180. This means that the unmarked angle of the triangle is equal to (180-153)=27.
Angles in a triangle add to 180. This means:
(x-4)+(2x+10)+27=180
3x+33=180
3x=147
x=49
What do you mean?.. Do you mean: e.g. How many tens are in 12.476? So you basically have the 70 as ten right? Well you need to count from the first number (12). So the answer to that example would be 1247. Forget about the decimal point.
Answer:
540, 541, 542
Step-by-step explanation:
let the number be n
hence the 3 consecutive numbers may be expressed as:
n , n+1, n+2
it is given that the sum of the 3 numbers is 1623
hence,
n + (n+1) + (n+2) = 1623
n + n + 1 + n + 2 = 1623
3n + 3 = 1623
3n = 1623 -3
3n = 1620
n = 1620 / 3
n = 540
hence the numbers are
540, (540 + 1) , (540 + 2)
or
540, 541, 542
There are 460 decigrams in 4.6 decagrams. Hope this helps!
