If you have the following equation; 4x - 4.5 = 10.73x + 5.7 + 7x, what would you multiply each term by to get rid of the decimal
posledela

Answer:

100

Step-by-step explanation:

You are given the equation

4x-4.5=10.73+5.7+7x

There are 5 coefficients:

4, \ -4.5,\ 10.73,\ 5.7,\ 7

Two of them are integers

4,\ 7

two of them are decimals with one digit after point

-4.5,\ 5.7

and one is a decimal with two digits after point

10.73

To get rid of fractions, we have to get rid of digits after point. The maximum number of digits after point is 2, then we have to multiply the equation by 100:

400x-450=1,073x+570+700x

All sides of quadrilateral ABCD ABCD A, B, C, D are tangent to circle PPP. What is the perimeter of the quadrilateral below?
noname [10]

Answer:

The answer is below

Step-by-step explanation:

A tangent is a line which touches a circle at one point. The angle between a tangent and a circle is 90°.

The two tangent theorem states that tangent that meet at the same point are equal in length.

Therefore:

CD = c + d

but c = 5.1, hence:

CD = 5.1 + d

12.1 = 5.1 + d

d = 7

AD = a + d; but AD = 12.2, d = 7

12.2 = a + 7

a = 5.2

AB = a + b; but b = 3.3

AB = 5.2 + 3.3 = 8.5

BC = b + c = 3.3 + 5.1 = 8.4

Perimeter of ABCD = AB + BC + CD + AD = 8.5 + 8.4 + 12.1 + 12.2 = 41.2
