If a jug is 1/5 full and weighs 250g and 4/5 full and weighs 550g how much does the jug weigh empty
Alika [10]
1/5 full =250g
4/5 full =550g
550g-250g=300g=3/5 without jug
1/5 without jug=300g/3=100g
250g-100g=150g

<u>The jug weighs 150g empty</u>

If sin(A+B)=1/2 &amp; sin(A-B)=1/3 find sin(2A)
timofeeve [1]

Answer:

sin(2A) = (2√2 + √3) / 6

Step-by-step explanation:

2A = (A+B) + (A−B)

sin(2A) = sin((A+B) + (A−B))

Angle sum formula:

sin(2A) = sin(A+B) cos(A−B) + sin(A−B) cos(A+B)

sin(2A) = 1/2 cos(A−B) + 1/3 cos(A+B)

Pythagorean identity:

sin(2A) = 1/2 √[1 − sin²(A−B)] + 1/3 √[1 − sin²(A+B)]

sin(2A) = 1/2 √(1 − 1/9) + 1/3 √(1 − 1/4)

sin(2A) = 1/2 √(8/9) + 1/3 √(3/4)

sin(2A) = 1/3 √2 + 1/6 √3

sin(2A) = (2√2 + √3) / 6

Which shows the correct first step to solving the system of equations in the most efficient manner? 3 x 2 y = 17. X 4 y = 19. X
Shkiper50 [21]

The correct first step to solving the system of equations in the most efficient manner is x = -4y +19.

The given system of equations is;

\rm 3 x + 2 y = 17\\\\x + 4 y = 19

<h2>What is the first step to solving an equation?</h2>

The first step would be to rearrange the variables in the second equation so we have a defined expression for x.

We would want to do this so we could then plug in the defined expression for x into the other equation and solve for the other variable.

x + 4y = 19

Rearrange this by getting the 4y to the other side.

We can get 4y on the other side by subtracting 4y from both sides

x + 4y - 4y = 19 - 4y

x = -4y + 19

Hence, the correct first step to solving the system of equations in the most efficient manner is x = -4y +19.

Kesley is thinking of a number. She says that it’s the sum of a number and nine. Multiplied by 2/3, is equal to -18.
Aliun [14]

Answer:

Only the firsts and fourth choices (\frac{2}{3}(x+9)=-18 and \frac{2}{3}x+6=-18)

Step-by-step explanation:

Turn the equation into words:

"A number plus 9"

(x+9)

"Multiplied by \frac{2}{3}"

\frac{2}{3} (x+9)

"Is equals to -18"

\frac{2}{3}(x+9)=-18

Distribute to find the second equation:

\frac{2}{3}(x+9)=-18\\\frac{2}{3}x+6=-18
