You would use the sine function
sin(x)=opposite/hypotenuse
sin(45)=6√2/x (cross multiply)
x*sin(45)=6√2
x*√2/2=6√2 (multiply both sides by 2)
x*√2=12√2 (divide both sides by √2)
x=12 so C

Hope this helps

Which equation can be used to represent six added to twice the sum of a numbee and four is equal to one half of the difference o
Ronch [10]

Answer:  6 + 2 (x+4) =   \frac{3}{2}(3-x)

Step-by-step explanation:

let the number be x , then :

six added to twice the sum of a number and four means :

6 + 2 (x+4)

one half of the difference of three and the number means :

\frac{3}{2}(3-x)

combining the two , we have

6 + 2 (x+4) = \frac{3}{2}(3-x)

Holly wants to save money for an emergency. Holly invests 1,500 in an account that pays an interest rate of 6.75%. How many year
lina2011 [118]
The formula is
A=p (1+r)^t
A future value 7300
P present value 1500
R interest rate 0.0675
T time?
7300=1500 (1+0.0675)^t
Solve for t
Divide both sides by 1500
7300/1500=1.0675^t
Take the log for both sides
Log (7300/1500)=t×log (1.0675)
Divide both sides by log (1.0675)
T=log(7,300÷1,500)÷log(1.0675)
T=24.2 years round your answer to get 24 years

Hope it helps!

Fynjy0 [20]

Answer:

x = 0

Step-by-step explanation:

3(x - 1) = 2x - 3 + 3x

3x - 3 = 2x - 3 + 3x

0 - 3 = 2x - 3

0 = 2x

2x = 0

x = 0 ÷ 2
