Ulleksa [173]2 years ago
5 0

Solution:

Given the system;

\begin{gathered} 4x+6y=32.............equation1 \\  \\ 3x-6y=3..............equation2 \end{gathered}

Add equation1 to equation2, we have;

\begin{gathered} 4x+3x+6y-6y=32+3 \\  \\ 7x=35 \\  \\ \frac{7x}{7}=\frac{35}{7} \\  \\ x=5 \end{gathered}

Substitute x = 5 in equation2;

\begin{gathered} 3x-6y=3 \\  \\ 3(5)-6y=3 \\  \\ 15-6y=3 \\  \\ 6y=15-3 \\  \\ 6y=12 \\  \\ y=2 \end{gathered}

ANSWER:

x=5,y=2

Solve and graph, showing your work.
Alika [10]
For the inequality y - 4 > -7, get y by itself by adding 4 to both sides. Now you have y > -3.
For the inequality y - 1 < 6, get y by itself by adding 1 to both sides. Now you have y < 7.

Graph the set y > -3 and y < 7. It should look like this:

a recipe calls for 7 ounces of peanuts and 5 ounces of chocolate chips. How many ounces of peanuts would be needed in a one poun
kompoz [17]
1 pound is 16 ounces. And we need to keep the ratio of 7 oz almonds and 5 oz raisins.

If I multiply each quantity by the same number, the ratio should stay the same. So

7(N) + 5(N) = 16

12 N = 16

N = 16/12 = 4/3


So we need 7(4/3) = 28/3 oz of almonds = 9.33 ounces of almonds.
And we need 5(4/3) = 20/3 oz of raisins = 6.67 ounces of raisins.

Together, these make 16 oz or 1 pound. And they still have the 7 almond/5 raisin ratio.

Two candles of equal length are lit at the same time. One candle takes 6 hours to burn out, and the other takes 9 hours to burn
GuDViN [60]

Answer:

4.5 hours

Step-by-step explanation:

Given: One candle takes 6 hour to burn out

           Other candle takes 9 hours to burn out.

Lets assume the time at which slower burning candle be exactly twice as long as the faster burning one be "x". and lenght of candle initially be "1".

Taking one candle as Candle A

            Other candle as Candle B.

As given both the candle is of equal length.

Now, putting up the equation to find the time at which lenght of candle B is twice as candle A.

∴ Length of candle=  2(1-\frac{x}{6} )= (1-\frac{x}{9})

Solving it knowing length is constant and using distributive property of multiplication

⇒ 2-\frac{2x}{6} = 1-\frac{x}{9}

subtracting both side by 2

⇒ \frac{-2x}{6} = -1 -\frac{x}{9}

Adding both side by \frac{x}{9}

⇒ -\frac{2x}{6} +\frac{x}{9} = -1

Taking LCD of 9 and 6 as 18

⇒ \frac{-2x\times 3+x\times 2}{18}= -1

Multiplying both side by 18

⇒-6x+2x= -18

⇒-4x= -18

Multiplying both side by -4

⇒ x= \frac{-18}{-4}= \frac{9}{2}

∴ x= 4.5 hours

Hence, 4.5 hours is the time at which slower burning candle be exactly twice as long as the faster burning one.

How do you solve this?
algol [13]

Answer:

It's asking for you to calculate the volume of a cylinder and multiply it by 2/3. This is because the question is asking how much water is in a cylindrical vase with the height and radius.

The formula to calculate the volume of a cylinder is : 3.14 (r^2) (h)

R being the radius and H being the height.

Plug in the values then multiply it all by 2/3

Hoped this help you solve your problem.
