Let, his original money = x
It would be: x * 1/2 = 120 
x = 120 * 2
x = 240

In short, Your Answer would be $240

Hope this helps!

Simplify. remove grouping sbols and combine like terms
harina [27]

Answer:

5a^2+12b^2-40b

Step-by-step explanation:

First distribute the -4 to the 2b and -3b. This leaves you with 5a^2-8b+12b(b+4)

Now you can distribute the 12b to b and +4. This leaves you with 5a^2-8b+12b^2+48b

Now you can combine your like terms leaving you with 5a^2+12b^2-40b.

What is the area of a circle?
Andru [333]

The area of a circle is the size of the 2-dimensional space inside the circle's
closed curved boundary.

The area can be calculated in terms of known linear measurements of the circle:

-- Area  =  (π) x (radius)²

-- Area  =  (π/4) x (diameter)²

-- Area  =  (1/2) x (circumference) x (radius)

-- Area  =  (1/4) x (circumference) x (diameter)

Any of these formulas will give you the area.  The one you decide to use
just depends on what you already know about the circle.

Triangle E D F has sides that are of varying lengths. Side E D has a length of 4 and side E F has a length of 9.
9966 [12]

Answer:

D E + E F greater-than D F

5 less-than D F less-than 13

Triangle D E F is a scalene triangle

Step-by-step explanation:

we know that

The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side

we have the triangle EDF

where

ED=4\ units\\EF=9\ units

<u><em>Applying the triangle inequality theorem</em></u>

1)

ED+EF > DF\\4+9 > DF\\13 > DF\\DF < 13\ units

2)

ED+DF > EF\\4+DF > 9\\DF > 5\ units

so

The length of DF is the interval -----> (5,13)

The triangle DEF is a scalene triangle (the three length sides are different)

therefore

<em>The statements that are true are</em>

D E + E F greater-than D F

5 less-than D F less-than 13

Triangle D E F is a scalene triangle
