There are 46 left-handed students in Tom's school.
An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the liketerms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
We can use a proportion to solve the problem:
10 left-handed students out of 85 total students is equivalent to x left-handed students out of 391 total students:
10/85 = x/391
To solve for x, we can cross-multiply:
85x = 10 x 391
Then divide both sides by 85:
x = (10 x 391) / 85
Simplifying the right-hand side gives:
x = 46
Thus,
There are 46 left-handed students in Tom's school.

Answer: Joey's answer should be a square.
Step-by-step explanation: Given that Joey is asked to name a quadrilateral which is also a rhombus. We are to find Joey's answer.
Rhombus : a quadrilateral having all the four sides equal and diagonals bisect each other perpendicularly.
We know that the only quadrilateral having four equal sides and diagonals bisecting each other perpendicularly is a SQUARE.
Also, a square has all angles as right-angles in addition.
Therefore, Joey's answer should be a square.
-4x + 4x*
______
-32x+32
* meaning squared
1.625 rounded to the nearesttenth is 1.6.
We have,
When rounding a number to the nearesttenth, you look at the digit in the hundredth place. If it is 5 or greater, you round up.
If it is less than 5, you round down. In this case, the digit in the hundredthplace is 2, which is less than 5.
To round 1.625 to the nearesttenth, we look at the digit in the hundredthplace, which is 2.
Since 2 is less than 5, we round down and keep the digit in the tenthplace as it is.
Therefore,
1.625 rounded to the nearesttenth is 1.6.
