Answer:

3*r = 3

Step-by-step explanation:

$\dfrac{24}{r}=3\\\\24 = r*3\\\\\dfrac{24}{3}=r\\\\6 = r$ 6 is a solution.

$3*r=3\\\r =\dfrac{3}{3}\\\\r = 1\\$

6 is not a solution.

$7r = 42\\\\r =\dfrac{42}{7}\\\\r = 6$

6 is a solution

Julio says if you subtract 17 from my number and multiply the difference by - 2 the result is gonna be negative 12 what was Juli

Paha777 [63]

Answer:

Step-by-step explanation:

Taking an algebraic approach

let the number be n, then (n - 17) is 17 subtracted from number and

- 2(n - 17) = - 12 ( divide both sides by - 2 )

n - 17 = 6 ( add 17 to both sides )

n = 23

Thus Julio's number was 23

Use your shapes to create a new shape with an area of 1 square unit that is not a square. Trace your shape.

Elena-2011 [213]

A new shape with an area of 1 square unit that is not a square can be formed by combining two small triangles

<h3>How to determine the new shape?</h3>

The given parameters are:

Area of square = 1 square unit
Large triangles = 2
Medium triangles = 1
Small triangles = 4

The area of each small triangle is:

Area = 0.5 square unit

Multiply both sides by 2

2 * Area of triangle = 1 square unit

Substitute Area of square = 1 square unit

2 * Area of triangle = Area of square

This means that a new shape can be formed by combining two small triangles
