I am an array made with 40 tiles I have an odd number of rows and an even number of tiles in each of my rows the number of my rows plus the number of tiles in each of my rows equals 13 how many rows do I have .

Answers

There are 5 row and 8 tiles in each row calculated using two equation.

What are System of equation?

Simultaneous equations, system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.

There are four methods to solving systems of equations: graphing, substitution, elimination and matrices.

Given I am an array made with 40 tiles I have an odd number of rows and an even number of tiles in each of my rows the number of my rows plus the number of tiles in each of my rows equals 13

Let "r" be the number of row and "t" be the number of tiles in each row.

Since, array has total 40 tiles

Thus,

r * t = 40

Also given

r +t = 13

From comparing these equation

r = 5 or 8

Since row is odd given

thus, r = 5

and t = 8

therefore, Two equations are used to determine the five rows and eight tiles in each row.

An employee makes an hourly rate plus any tips they earn. This tip employee made a total of $400 by working 28 hours last week. If $253 of their total earnings was their tips, what is their hourly rate of pay?

Answers

To find the answer we must remove the tips amount from the total amount, and then divide what remains by the numbers of hours he worked. So we have: HourlyRate = (400 - 253) / 28 <=> HourlyRate = 147/28 <=> HourlyRate = $5.25

a box with no top is constructed from a 10 inch x 12 inch piece of cardboard by cutting out congruent squares from each corner of the cardboard and then folding the resulting tabs. We determined the volume of that box (in cubic inches) is given by V(x) = 4x³ - 44x² + 120x where x denotes the length of the side of the square which is removed from each corner (in inches), 0 < x < 5. Solve the inequality V(x)≥80 analytically and interpret your answer in the context of that example.
