A system of equations that has at least one solution is called inconsistent.
solmaris [256]

False. Because if it has one then it is consistent.

Source: If a consistent system has an infinite number of solutions, it is dependent . When you graph the equations, both equations represent the same line. If a system has no solution, it is said to be inconsistent. (https://www.varsitytutors.com/hotmath/hotmath.../consistent-and-dependent-systems)

What is 2 1/2 /1/3 ?
DanielleElmas [232]

Answer:

15/2

Step-by-step explanation:

My interpretation of your math expression is "2  1/2 divided by 1/3."

I prefer to write this as:

 5        1

----- ÷ -----

 2         3

which is equivalent to:

 5        3

----- * ----- = 15/2

 2        1

Ugo [173]

Step-by-step explanation:

1. Perimeter = 2 ( 5+4) = <u>18 cm</u>

Area = 5 × 4 = <u>20 cm^2</u>

2. Perimeter = 2 (5+5) = <u>20 cm</u>

Area = 5 × 5 = <u>25 cm^2</u>

3. Cups of seed needed per sq. meter = Area of the rectangle backyard

= 6 × 7

= <u>42 </u><u>cups</u><u> </u><u>of</u><u> </u><u>seed</u>

4. Feet of fence needed = Perimeter of the Square garden

= 2(8+8)

<u>= 32 feet</u>

5. Perimeter of rectangular quilt = 2 (4+6) feet

= <u>20 feet</u>

6. Area of the room = 9 feet × 8 feet

= <u>72 feet^2</u>
