Tema [17]

Answer:

(3x+5y)/8

Step-by-step explanation:

The total amount is 150+250=400

We then do (3x+5y)/2 × 1/400

This equals (3x+5y)/800

We multiply that by 100 giving us the final answer.

I need help.<br> Math is really hard

alekssr [168]

Answer:

The value of x in terms of b is: $\mathbf{x=-\frac{6}{2b}}$

The value of x when b is 3 is: x = -1

Step-by-step explanation:

We are given the function: $-2(bx-5)=16$

First we need to find

The value of x in terms of b

We need to find value of x

$-2(bx-5)=16$

Multiply -2 with terms inside the bracket

$-2bx+10=16$

Subtract 10 from both sides

$-2bx+10-10=16-10\\-2bx=6$

Divide both sides by -2b

$\frac{-2bx}{-2b}=\frac{6}{-2b}\\x=-\frac{6}{2b}$

So, The value of x in terms of b is: $\mathbf{x=-\frac{6}{2b}}$

The value of x when b is 3

We have the equation for the value of x in terms of b:

$\mathbf{x=-\frac{6}{2b}}$

Put b = 3

$x=-\frac{6}{2(3)}\\x=-\frac{6}{6}\\x=-1$

So, The value of x when b is 3 is: x = -1

7. An aquarium is shown below. The

Mnenie [13.5K]

Answer:

1920 in³

Step-by-step explanation:

The volume of the water can be gotten by calculation the volume of the aquarium it fills/occupies.

Since the water fills to exactly three inches below the top of the aquarium, hence the height of the water in the aquarium is given as:

height of water = 13 in - 3 in = 10 in

Therefore the volume of the water in the tank is given by the formula:

Volume of water = height of water * breadth of tank * length of tank

Volume of water = 10 in * 8 in * 24 in = 1920 in³
