Help please thank you!!!!

1. You have that:

- The trapezoids are similar.
- The larger base of the smaller trapezoid is 18 m and its area is 310 m².
- The larger base of the larger trapezoid is 32 m.

2. Then:

Sides=18/32
Sides=9/16

Area=(9/16)²
Area=81/256

3. Now, you can find the area of the larger trapezoid, as below:

81/256=310/x
81x=(310)(256)
x=79360/81
x=980 m²

Therefore, the answer is: The area of the larger trapezoid is 980 m².

I thought of a number, added 4 5/7 to it, and got the number 12 times as big as my original what was my number

Genrish500 [490]

Let's call the number you thought of n. Then what the two steps you took can be written as an equation:
$n+4\frac{5}{7}=12n$

Subtract n to get all of your variables to one side:
$4\frac{5}{7}=11n$

At this point, I recommend turning your mixed number into an improper fraction. It will make things easier later on:
$\frac{33}{7}=11n$

Now divide both sides by 11 to get the value of n:
$\frac{3}{7}=n$
