Cell Phone Company A charges $20 each month plus $0.03 per text. Cell Phone Company B charges $5 each month plus $0.07 per text.

Ymorist [56]

Cost of company A=monthlyfee+text=20+0.03t where t=number of texts
A=20+0.03t

company b is monthlyfee+texts=5+0.07t
B=5+0.07t

1.
c=20+0.03t
c=5+0.07t
using c for cost is confusing because we can't tell which is for which company

2.

equal, means the costs are equal so
20+0.03t=5+0.07t
minus 5 from both sides
15+0.03t=0.07t
minus 0.03t from both sides
15=0.04t
divide both sides by 0.04
375=t
the answer is 375 texts

What is the value of x? A. 2 Units B. 3 Units C. 5 Units D. 8 Units

Fudgin [204]

You need the formula for geometric mean for right triangles as it applies to the altitude. For us, that formula will be $\frac{BD}{AD}=\frac{CD}{BD}$ where BD is your altitude. The formula then, filled in accordingly, would be $\frac{10}{x}=\frac{4x}{10}$ . We cross multiply to get that $4x^2=100$ . Divide both sides by 4 to get $x^2=25$ , so x = 5. Choice C is the one you want.
