Answer:

70 inches

Step-by-step explanation:

Finding the perimeter of a rectangle means taking two sides of the same length and adding them to two sides of a seperate length. 20 times two is 40, 180 minus 40 is 140, 140 divided by two is 70. Meaning that the length of the rectangle must be 70 for the width to be 20 and the perimeter to be at least 180 inches.

20x2 = 40 in width
180-40= 140
140/2=70
70 inches

So you start by doing 18 times 6, you get 108. Then you subtract 108 from 260 and get your answer, 152!

Two thirds of a number is no more than -10

Aliun [14]

Let x be the number in the problem. When it states that x is "no more than -10", it means than it is less than or equal to -10. So, we have

$\frac{2}{3}$ x≤-10

In order to cancel out the $\frac{2}{3}$ on the left and isolate x, we multiply both sides by $\frac{3}{2}$ (since $\frac{3}{2}$ · $\frac{2}{3}$ =1). Thus, we have

x≤-10· $\frac{3}{2}$ =-15

Therefore, x≤-15

Determine whether or not the relation is a function. Please help asap

OLga [1]

Answer:

A function can have many x values for a given y value and still be a function but it cannot have many y values for a given x value. You can easily test this by graphing the equation and doing the vertical line test by seeing if a vertical line will intersect the graph only once at all x values, if it passes it is a function. In short what you have here is a function
