A sum is addition. This problem is division... But 4/3= 1.33333.
Answer:
X =25
Step-by-step explanation:
5 times the 10 making it 50
Makes it so 2x=50
Do 50/2 to get 25
Check answer
2 X 25 / 5 = 10
Hope this helped
1 dozen = 12
12 x 2 = 24
8/3 = x/24
3x=192
x=64
two dozen socks would cost $64
Answer:
B (Y, N, N)
Step-by-step explanation:
a) y = 1/3x, so each value satisfies it. This is true.
b) If "a" is "Y" then b has to be no
c) 1 * 11 = 11
2 * 2 = 22
3 * 5 = 15
The last equation does not follow the rules for the previous two equations, so it is no.
Thus, the answer is B (Y, N, N)
Step-by-step explanation:
Answer:
Last choice is correct.
Step-by-step explanation:
Given that ∠C=90°, ∠B=30°, c=10
We know that sum of all angles in a triangle is 180 degree.
∠A+∠B+∠C=180°
∠A+∠30°+∠90°=180°
∠A+∠120°=180°
∠A=60°
Now we can use sin or cos whichever applicable to find missing sides
2b=10
b=5
Similarly
a=8.6602
Hence last choice is correct.
