7x=5x-3 1. Subtract 5x from both sides
2x=3 2. Divide both sides by 2
X=3/2 or 1.5
11a = 18a + 21
11a - 18a = - 18a + 21
-7a = 21
7a = -21
a = -21/ 7
a = -3
Answer:
tan theta = 2 sqrt(5) /15
Step-by-step explanation:
sin theta = opp / hypotenuse
sin theta = 2/7
We can use the Pythagorean theorem to find the length of the adjacent side
a^2 + b^2 = c^2
2^2 +adj^2 = 7^2
4 + adj^2 = 49
adj ^2 = 49-4
adj^2 = 45
Taking the square root of each side
adj = sqrt(45) = sqrt(9*5) =sqrt(9) sqrt(5) = 3 sqrt(5)
The tan theta = opp/ adj
tan theta = 2 / 3 sqrt(5)
Multiply by sqrt(5) / sqrt(5)
= 2 sqrt(5) / 3 *5
= 2 sqrt(5) /15
Answer: $1,000
Explanation:
In bonds, the face value is the value of bond when it is held to maturity. Since the face of the bond is $5,000, the value of Arthur's bond when he holds it until maturity is $5,000.
To get Arthur's earnings by holding his bond until maturity, we subtract the face value to the amount he paid for the bond. Since the face value is $5,000 and he paid $4,000 for that bond, he earned $1,000 for the bond because $5,000 - $4,000 = $1,000.
Answer:
its B
Step-by-step explanation:
cuz -3 1/3 would be turned into -10/3 by multiplying 3*3 which will give u 9 and adding 1 which is 10 then u put the 10 on top and keep the 3 as bottom.
and then flip the 4/9 which will turn into 9/4 so now u can multiple intead of divide
-10/3 * 9/4 and then youll get ur answer.
