Answer: 72
72/8 will get you 9. To see if the answer is correct Multiply 9*8.
B. 25 Km. The measure of BC is 25 km.
The easiest way to solve this problem is using the cosine theorem c = √a²+b²-2ab*cos A.
BC = √AC²+AB²-2(AC)(AB)*cos A
BC = √(21km)²+(14km)²-2(21km)(14km)*cos 89°
BC = √441km²+196km²-588km²*(0.017)
BC =√637km²-10.26km²
BC = √636.74km²
BC = 25.03km ≅ 25
Answer:
Step-by-step explanation:
area=16×8+1/2×3×6
=128+9
=137 sq. ft.
The other number is 5 less than 3 times the other so the other number will be
3x-5
We are given that they add up to 31, so we can write
x+(3x-5) = 31
4x - 5 =31
Answer:
y = 5
x = 10
Step-by-step explanation:
-4(2y) + 11y
-8y + 11y = 15
3y = 15
/ 3 /3
y = 5
x = 10
