Step-by-step explanation:
-4/5 x 7= -28/5
3=15/5
-28/5 + 15/5= -13/5
Answer:
20 -> 10 × 2 (2 is prime)
10 -> 5 × 2 (both are prime)
So you have 2 × 2 × 5, which can also be written as 2² × 5, which is your answer. I hope this helps!
Step-by-step explanation:
By Cosine Rule:
CosT = (s² + r² - t²) /(2sr)
<span>CosT = (10² + 11² - 7²) /(2*11*10)
</span>
<span>CosT = 172 /220 </span>≈ 0.7818
T = Cos⁻¹(0.7818)
T ≈ 38.57°
T ≈ 38.6°
Let us say that the number is x.
So the first step that Julio do is to cube the number so
that:
x^3
Then the next he did was take cube root of the number, so
that:
(x^3)^(1/3)
Solving this would result in:
x^(3/3) = x^1 = x
Since he ends up with 20, therefore:
x = 20
<span>Julio started and ended with the same number which is 20.</span>
