What is the driving time for a 1700 miles trip if you Drive an average speed of 53 mph

There are 46 left-handed students in Tom's school.

What is an expression?

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:

Step-by-step explanation:

As in the triangle RST,

Because if in a triangle two angles equal one another, then the sides opposite the equal angles also equal one another.

Incenter is obtained by the Intersection of a triangle's three angle bisectors and it is equidistant from the three sides of the triangle.

So, RP and TP are the angle bisectors of ∠R and ∠T respectively.

Isosceles triangles mean that 2 sides of the triangle are congruent. Since triangle RST is isosceles and P is its incenter, that means that PT and PR must be congruent, also. PRT is an isosceles triangle.
