Becky has a board that is 2 and 3/4 feet long. She needs to cut the board into 11 pieces of equal length. How long should each p
zzz [600]

Answer:

1/4 feet long should each pieces be.

Step-by-step explanation:

Unit rate defined as the rates are expressed as a quantity of 1 such as 3 miles per second or 4 km per hour

As per the statement: Becky has a board that is 2 and 3/4 feet long.

⇒ Length of a board = 2\frac{3}{4} =\frac{11}{4} feet

Also, she need to cut the board into 11 pieces.

by unit rate definition:

\text{Unit rate per pieces} = \frac{\frac{11}{4} }{11}

or

\text{Unit rate per pieces} = \frac{11}{4} \times \frac{1}{11} = \frac{1}{4}

Therefore, 1/4 feet long should each pieces be.

Find the ordered pairs for the x- and y-intercepts of the equation 3x - 2y =18
Len [333]
X-int:let y=0
3x-2(0)=18
3x=18
divide both sides by 3
therefore x=6
y-int:let x=0
3(0)-2y=18
-2y=18
we divide both side by -2
therefore y=-9
