Find the number for which 8.4% is 17.22 kg

The number is 205 kg

Step-by-step explanation:

Let

x > the number

we know that

8.4%=8.4/100=0.084

The linear equation that represent this problem is equal to

0.084x=17.22

Solve for x

Divide by 0.084 both sides

x=17.22/0.084

x=205 kg

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

ca = ec

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.
