Answer:

5

Step-by-step explanation:

The general form of the equation for a line is:

where the number that accompanies the x is the slope of the line, and the number is called the y-intercept of the line.

In this case we have the equation:

we can see that we don't have any number added, so in this line , and the number that accompanies the x is 5, so

which is the slope of the line

So the answer is 5.

Distribute

(2/5) (a) + (2/5) (b) + (3/5)(a) +(3/5)(c)

= 2/5a+2/5b+3/5a+3/5c

Combine like terms

2/5 a + 2/5 b + 3/5 a + 3/5 c

= ( 2/5 a + 3/5 a ) + ( 2/5 b) +(3/5 c)

= a + 2/5 b +3/5 c

The total number of boxes that Marnie had to pack was 25.

What are percentages?

A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”

Given here: Marnie packed 18 boxes in 3 hours, which was 72% of the total number of boxes she had to pack.

Let the total number of boxes that she packed is x then we have

72/100 ×x=18

x=18×25/18

x=25

Hence, The total number of boxes that Marnie had to pack was 25.

Answer:

Rhombus

Rectangle

Square

Step-by-step explanation:

A parallelogram is a shape of four sides, quadrilateral, that has equal and opposite sides. In this case, the problem is asking to name three kinds of parallelograms to complete the hierarchy.

In the hierarchy, quadrilaterals come first because a quadrilateral is a polygon of four edges, no matter if the sides of the polygon are irregular.

Then comes the parallelograms that are quadrilaterals with equal, opposite sides.

And some types of parallelograms are:

Rhombus in which all the sides are equal but the angles are not right angles

Rectangle that has right angles

Square all the sides are equal and it has right angles
