Answer:
24/25
Step-by-step explanation:
I use the keep change flip method.
Keep the first fraction the same (leave it alone)
4/5 ÷ 5/6
Change the symbol from ÷ to ×
4/5 × 5/6
Flip the fraction (write its reciprocal)
4/5 × 6/5
Multiply across
Answer:
x can be 4.99 to make y>0
Step-by-step explanation:
y= −1.5x + 7.5
For what value(s) of x is: y>0
lets solve for x first:
-1.5x + 7.5 = 0
-1.5x * 10 + 7.5 * 10 = 0 * 10
-15x + 75 = 0
-15x + 75 - 75 = 0 - 75
-15x = -75
x = -75/-15
x = 5
to make y>0, we substitute x<5 into the formula
y > −1.5(4.99) + 7.5
y > 0.15
therefore, x can be 4.99 to make y>0

Hello! Remember you have to write complete questions in order to get good and exact answers. Here I'll assume you want an explanation for polygons, quadrilaterals and parallelograms. So let's get started:
1. Polygon: A <em>polygon </em>is any flat shape that is closed and has straight lines as its sides.
2. Quadrilateral: A <em>quadrilateral </em>is a polygon that has four sides. Those sides can be either equal or not.
3. Parallelogram: A <em>parallelogram </em>is a polygon and also a quadrilateral because it has four sides such that the opposite sides are parallel and equal in length.
<u>In conclusion:</u>
- A parallelogram is both a polygon and a quadrilateral
- A quadrilateral is a polygon

Answer:
No.
Step-by-step explanation:
1. Since 19 is a prime number, it only has two factors: 1 and 19. Therefore, 3 is not a factor of 19 because no natural number multiplied by 3 equals 19.
28÷7= 4
4+111= 115
115-16= 99
