34kurt

Answer: \$175

Step-by-step explanation:

Since Gloria cannot pay for each minute talked but for packages of 200 minutes at the rate of $25 each, we have to make calculations according to these conditions as follows:

Month 1:

Gloria talked on her cell phone for 320 min. So, she had to buy 2 packages of 200 min for \$25 each package.

Hence:

(\$25) 2= \$50

Month 2:

Gloria talked on her cell phone for 243 min. So, she had to buy again 2 packages of 200 min for \$25 each package.

Hence:

(\$25) 2= \$50

Month 3:

Gloria talked on her cell phone for 489 min. So, she had to buy 3 packages of 200 min for \$25 each package.

Hence:

(\$25) 3= \$75

Then, if we take the total Gloria had to pay for the frist three months, we have:

\$50 + \$50 + \$75= \$175

Can i have help please. Step by step
nignag [31]

Answer: It's in the step-by step explanation

Step-by-step explanation:

I just learned about this too. I'll use what I know to help you out.

According to whatever law of the circle, where you have two intersecting lines within the bounds of a circle(that'd be TQ and SW), the product of the divided segments will equal each other.

So to put that in terms, TU times QU = SU times WU.

So let's get the value of segment TU, which is 1.5

Then let's get the value of segment of QU, which is 4.

Now let's get the value of WU, which is 3. We don't know what SU is yet. So put it in algebraic form.

1.5(4)=3x

6=3x

2=x
