Answer:
132 feet
Step-by-step explanation:
we know that
The scale is equal to
That means ---> 1 inch in the model represent 12 feet in the actual
To find the actual dimensions of the airplane, divide the dimensions of the model by the scale
so
A plane requires 3300 gallons of fuel and 75 minutes to make a round trip to Prague, and it takes 5700 gallons

We have the expression:
And we need to solve this for x.
Let's solve this expression and then see which of the options is the correct one.
The first step to solve this is that we need for the two sides of the equation to have the same base. (the number 5 on the left side is the base, so we need to also have a 5 as the base on the right side).
We do this by noting that:
We know that 25 is equal to 5 squared (because 5x5 is 25)
So the first step is to substitute 25 for 5 squared:
Since we have the same base on both sides (5), we follow the rule:
• If we have the same base on both sides of an equation, the exponents have to be equal
Thus, the second step to solve is to equal the exponents:
Finally, to solve this equation for x, we just need to add 1 to both sides to get rid of the -1 on the left side:
And the third step is:
As we can see, these three steps are represented in the third option In which we get the same result of x=3.
Answer: x=3
Answer:
Remove 9 from triangle B to A
Step-by-step explanation:
Given
Three Triangles
A: 1,2,3
B: 7,8,9
C: 4,5,6
Required
Make their sum equal
First, we need to calculate the sum in each triangles;
Remove 9 from triangle B to A
At this point, we have:
<em>Hence, the solution is to remove 9 from B to A</em>
