VERY URGENT !Gloria texts 18 words in the same amount of time it takes Erica to text
25. Assuming the relationship is
proportional, if Erica texted 500 words,
how many did Gloria text?

Gloria would text 360 words if Erica texted 500 words.

Step-by-step explanation:

Let 'y' be the number of words Gloria texts

Let 'x' be the number of words Erica texts

Given that the relationship is  proportional

y ∝ x

y = kx

where 'k' is called the constant of proportionality

Given

substituting the values to determine the constant of proportionality 'k'

k = y / x

   = 18 / 25

Thus, the constant of proportionality = k = 18/25

When Erica texted 500 words, we need to determine the number of words Gloria will text.

so

k = 500

y = ?

k = y / x

y = kx

  = 18 / 25 × 500

  = 360 words

Thus, Gloria would text 360 words if Erica texted 500 words.

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
