area is measured in "square" units. ... Area of a square = side times side. Since each side of a square is the same, it can simply be the length of one side squared. If a square has one side of 4 inches, the area would be 4 inches times 4 inches, or 16 square inches.

so you multiply the sides by each other.

The sum of 1/3 and twice a number is equal to 2/3 subtracted from three the number.find the number

Zigmanuir [339]

The number = y

2y + 1/3 = 2/3 - 3y
(add 3y to both sides)
5y + 1/3 = 2/3
(subtract 1/3 from both sides to isolate y)
5y = 1/3
(divide by 5)
y = 1/15

Y + 3y + 5y = -18 what is the value of y

ANEK [815]

Answer:

y = -2

Step-by-step explanation:

Step 1: Combine like terms.

$(y+3y+5y)=-18$
$9y=-18$

Step 2: Divide both sides by 9.

$9y/9=-18/9$
$y=-2$

Step 3: Check if solution is correct.

$-2+3(-2)+5(-2)=-18$
$-2-6-10=-18$
$-18=-18$

Therefore, y = -2.
