Hi! Well, lets think! 9 divided by 3 is 3. We all know 3x2 is 6. And if we use a calculator we come to find out that 4.5 divided by 1.5 is 3.......All these numbers have 3 in common. So if we multiply 5.5x3 we have 16.5 as the answer. Im doing the same test right now lol #k12gang but i hope this helped!

Solve the system of equations by any method. 5x+9y =16 x+2y =4

Alisiya [41]

Answer:

The system of equations has one solution at (-4, 4).

Step-by-step explanation:

We are given the system of equations:

$\displaystyle\left \{ {{5x+9y=16} \atop {x+2y=4}} \right.$

We can use elimination to solve this system. We need to multiply the second equation by -5 so we can cancel out our x-terms.

$-5\times(x+2y=4) \rightarrow -5x - 10y = -20$

Therefore, our system now becomes:

$\displaystyle\left \{ {{5x+9y=16} \atop {-5x-10y=-20}} \right.$

Now, we can add these two equations together and solve for y.

$\displaystyle(5x + 9y) + (-5x - 10y) = 0 - y\\\\16 + (-20) = -4\\\\-y = -4\\\\\frac{-y}{-1}=\frac{-4}{-1}\\\\y = 4$

Now, we can substitute our value for y into one of the equations and solve for x.

$x+2(4)=4\\\\x + 8 = 4\\\\x = -4$

Therefore, our final solution is (-4, 4).

A spinner has 3 sections colored red, yellow, and blue. The probabilities of the spinner landing on red and yellow or 0.25 and 0

JulijaS [17]

It would be 37.5 times, which rounded up would be about 38 because blue would be .25 of the spinner, so you would expect it to land on blue 25% of the time. Hope this helps!!

Answer:

The third option, -1/2(30) = -15

Step-by-step explanation:

If it decreases by 1/2, we know it has to be -1/2, and the days we are given are 30. We need to multiply -1/2 by 30 in order to find the water level after 30 days, which would be -15 (inches?) I hope this helped.
