57.50 - 8 = 49.50 more she needs to save

49.50 / 4.50 = 11

she needs to save for 11 weeks

4.5x+8=57.5

What two numbers multiply to equal 50 and add up to equal -15

Tanzania [10]

The two numbers are 5,10. Which is multiply to equal 50 and add up to equal 15.

Step-by-step explanation:

Step:1

Let, X,Y.

Where X, Y are two numbers.

Step:2

Form the Multiplication equation from given,

X×Y=50 (∵ Multiply to equal 50)

Step:3

Form Addition equation from given,

X+Y= 15 (∵ Add equal to 15)

Step:4

Check for alternatives to satisfy both equations

Assume, X=1, Y=14

1+14=15 (Satisfy addition equation)

1×14=14 (Not satisfy multiplication equation)

Assume, X=2, Y=13

2+13=15 (Satisfy addition equation)

2×13=26 (Not satisfy multiplication equation)

similarly.,

assume X=5, Y=10

5+10=15 (Satisfy addition equation)

5×10=50 (Satisfy multiplication equation)

So, the two numbers are 5,10.

Andy is designing a dice tray in the shape of a rectangular prism to use during a role-playing game. The tray needs to be three

Dmitry_Shevchenko [17]

Answer:

$3x^2 + 15x - 252 = 0$

Step-by-step explanation:

The volume of the prism is 252 cubic centimeters.

The volume of a rectangular prism is gotten by the formula:

V = l * w * h

where l = length

w = width

h = height

The height of the prism is 3 cm.

Let x be the width of the prism.

The length of the prism is 5 cm longer than the width.That is:

l = 5 + x

The volume of the prism is therefore:

V = (5 + x) * x * 3

$=> 252 = (5x + x^2) * 3\\\\252 = 15x + 3x^2\\\\=> 3x^2 + 15x - 252 = 0$

This is the equation that models the volume of the tray in terms of x.
