viktelen [127]

Answer: The answer is (n = 5r + 10).

Step-by-step explanation: Given that in a theatre, there are 15 seats in the first row, 20 seats in the second row, 25 seats in the third row, etc.

We are to write the linear equation that represents the number of seats 'n' in each row 'r'.

Now,

Number of seats in the 1st row = 15 = 5 × 3 = 5 × (1+2),

number of seats in the 2nd row = 20 = 5 × 4 = 5 × (2+2),

number of seats in the 3rd row = 25 = 5 × 5 = 5 × (3+2), etc...

Therefore, number of seats 'n' in the r-th row is given by the following linear equation -

n = 5 × (r+2), i.e., n = 5r + 10.

Thus, the required linear equation is n = 5r + 10.

Ye Li drew a quadrilateral that is both a rectangle and a rhombus. Name the quadrilateral and describe it using the properties o

son4ous [18]

We must look first for the properties given, so we have:
Rectangle - four sides, two pairs of opposite sides are parallel, four right anglesQuadrilateral - a four-sided figureRhombus - four sides, two pairs of opposite sides are parallel, all sides equal
So we're finding for a shape that has four sides that are all equal, with two pairs of parallel sides, and has four right angles. So from this description, we can say that it is a square. Squares have two pairs of parallel sides (like a rhombus and rectangle), four right angles (like rectangles), and four sides that are equal (like a rhombus). A square is also both a rectangle and a rhombus.

Which of the following numbers is a whole number? 1.) 0.3 2.) -2/3 3.) -8 4.) 3

Snowcat [4.5K]

Answer:

3

Step-by-step explanation:

A whole number is not a decimal or a fraction (unless the fraction can be simplified to a whole number). A whole number is also not negative. That would make it an integer.

Use the distributive property to write the expression without parentheses.<br> 7(4a +5)

LuckyWell [14K]

Answer:

28a + 35

Step-by-step explanation:

When you are using the distributive property, you need to multiply the number right outside of the paranethesis to both numbers. In this case, that number is 7. 4a and 5 are in the paranthesis, so we need to multiply 7 to 4a and 5. In the end, we get 28a and 35 or 28a + 35
