first off you put a plus sign. second off the answer is 345.5
Step-by-step explanation:
I used a calculator
we are given
equilateral triangle
we can see that triangle ACD is a right angled triangle
so, we can use Pythagoras theorem for this triangle
hypotenuse=AC
Adjacent=CD
opposite=AD=a
and
now, we can use Pythagoras theorem
and we get
now, we can plug values
now, we can solve for a
so, option-A..........Answer
Answer:
The answer is B.
Step-by-step explanation:
When Elimination method is applied, you have to eliminate one of the variables from both equations. Firstly, both equations contain 4y so you can subtract it :
Next, you have to substitute x = 5 to any equations. I will choose to put in (2) :
Therefore, put your answer in coordinate form :
The answer is 42/3
4 2/3 × 6 1/2= 30.33 (30 1/3)
Ok see for doing percentage it is very easy just divide it by the main number I mean see if there is a food price 10 dollars and it has 20%off then u divide 20/10x100 u divide it by the actual number and then multiply it by 100 so the answer of my 20/10x100 is 10x20/100 ok so the answer is 2. The price is 2
