I believe x is equal to five. Try it. Hope this helps mate.
The sum of two consecutive even integers is at most seven more than half the sum of the next two consecutive even integers
two consecutive even integers: n, n+2
next two consecutive even integers n+4, n+6
n+(n+2) >= 7+1/2(n+4 +n+6)
combine like terms
2n+2 >= 7 +1/2(2n+10)
distribute 1/2
2n+2 >= 7+n+5
2n+2>= n+12
subtract n from each side
n+2>= 12
subtract 2 from each side
n>10
4 integers : 10, 12 ,14, 16
Well, 2.3•10^3 is the same as 2.3•1000. So move the decimal place three times to the right and you get a final answer of 2300.
Answer:
see explanation
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the given angles from 180 for B
B = 180° - (90 + 47)° = 180° - 137° = 43°
-------------------------------------------------------------
tan47° =
= 
Multiply both sides by 14
14 × tan47° = a, thus
a ≈ 15.0 (to the nearest tenth )
---------------------------------------------------------------
cos47° =
= 
Multiply both sides by c
c × cos47° = 14 ( divide both sides by cos47° )
c =
≈ 20.5 ( to the nearest tenth )
Answer:
10
Step-by-step explanation:
The answer is because:
a^2 + b^2 = c^2
8^2 + 6^2 = x^2
64 + 36 = x^2
100 = x^2
√100 = √x^2
10 = x
