Answer:

the first choice is the correct answer

Teresa, Eric, and Ryan sent a total of 99 text messages over their cell phones during the weekend. Eric sent 3 times as
faust18 [17]

I'll use t for the messages Teresa sent, e for messages Eric sent, and r for messages Ryan sent.

Therefore we have, t+e+r=99.

From the text we also know:

e=3r ; r=t+6

If we substitute in the original equation we get:

t+3(t+6)+t+6=99; By simplifying it we get

5t=75 , therefore t=75/5=15.

Since Teresa send 15 messages,Ryan sent 6 more then here, so he send 21. Eric sent three times the

messages Ryan sent so he sent 63 messages. If we add them together 15+21+63, we get the total of 99 messages.

What is the sum of 4.9 × 102 and 6.8 × 103?
dusya [7]

Answer:

The sum is

7.92\times 10^3

Step-by-step explanation:

We want to add

4.9\times 10^2 and 6.8\times 10^3

The sum of these two numbers is:

4.9\times 10^2 +6.8\times 10^3

This is the same as:

4.9\times 100 +6.8\times 1000

490 +6800=7290

We rewrite 7290 in standard form to get;

7.92\times 10^3
