Tannis's first machine could throw a car 27 meters. She studied her first machine and built a better one. Her second machine could throw a car 7 times as far. How far does the second machine throw a car?

Hello! Your answer would be 189 meters.

Step-by-step explanation:

First, let's examine the problem closely. It says that Tannis's first machine could throw a car 27 meters, but then she studied her first machine and built another one. So far we have one part of the problem that will get us to our solution, 27 meters. The next part is where we get our last two parts of our problem, the operation and the other factor. The second part of this problem says that Tannis's second machine could throw a car 7 times as far, meaning her second machine could throw a car 7 times farther then her first machine. We are given our operation, multiplication, first, and our second factor, 7, last. Then, we must look closely at the main question we are trying to How far does the second machine throw a car? We can form and evaluate an expression to answer this question. With the information we've gathered, we can form the expression: 27 meters x 7, and that equals 189 meters. I hope this helps and make sure you have an amazing day!

341

step-by-step explanation:
