sesenic [268]

Answer:

<h2>The answer is </h2><h2>B. 1/12</h2>

Step-by-step explanation:

step one:

From the problem state, we can actually conclude that Jamie wants to share the half sheet of cake among her 6 friends

step two:

we can express this problem mathematically as

=\frac{1}{\frac{2}{6} }

we can inverse the denominator and use a multiplication sign instead

\\\\= \frac{1}{2}*\frac{1}{6}

multiplying both denominators we have

\\\\= \frac{1}{12}

The answer is B 1/12

What is the perimeter, P, of a rectangle that has a length of x +8 and a width of y - 1?
Dafna1 [17]

Answer:

P=2x+2y+14

Step-by-step explanation:

Perimeter (P)of a rectangle = 2( l+b)

where l is the length and b is the width of the rectangle .

Here, l= x+8

and, b= y-1

so, P = 2{(x+8)+(y-1)}

= 2( x+8+y-1)

= 2(x+y+7)

=2x+2y+14
