4 less than half a number is equal to 2 more than the number
xxMikexx [17]

Answer:

-12

Step-by-step explanation:

Let that number be x. We can build an equation, and solve for x.

4 less than half of x is x/2-4.

2 more than x is x+2.

We are given that the two quantities are equal, so we have that x/2-4=x+2.

Adding 4 to both sides gives x/2=x+6.

Multiplying both sides by 2 gives x=2(x+6)=2x+12.

Subtracting 2x from both sides gives -x=12.

Multiplying both sides by -1 gives x=-12.

So, the number is \boxed{-12} and we're done!

The check is left as an exercise to the reader.

77%<br> Calculate the area of this triangle.<br> 14 cm<br> 11 cmi<br> 18 cm
RideAnS [48]

Answer:

A = 99 cm²

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = \frac{1}{2}  bh ( b is the base and h the perpendicular height )

Here b = 18 and h = 11 , then

A = \frac{1}{2} × 18 × 11 = 9 × 11 = 99 cm²

1/2x+2 = x/2x^2+8<br><br> Show work plz
Igoryamba

Answer:

x=24

Step-by-step explanation:

1/2x+2 = 1/2x^2+8

1/2x^2=1/4x

1/2x+2=1/4x+8

1/2x -1/4x =0.25x

0.25x+2=8

8-2=6

0.25x=6

0.25/6 = 24

x=24
