Is -¼ + 2 ¼y + 2 - y equivalent to y + 2 ?

Juliette [100K]

Answer: No

Step-by-step explanation:

$-\frac{1}{4}+2\frac{1}{4}y+2-y=y+2$

$(-\frac{1}{4}+2)+(2\frac{1}{4}y-y)=y+2\\$

$(\frac{(-1)+(4)(2)}{4})+(\frac{9}{4}y-y)=y+2$

$(\frac{-1+8}{4})+(\frac{(9)(1)-(4)(1)}{4} )y=y+2$

$(\frac{7}{4})+(\frac{9-4}{4} )y=y+2$

$(\frac{7}{4})+(\frac{5}{4})y=y+2$

T a linen sale Mrs. Earle bought twice as many pillowcases for $2 each as sheets for $5 each. If she spent less than $40, not in

Anettt [7]

For this case, the first thing we must do is define variables:
x: number of pillowcases
y: number of sheets
We now write the system of equations:
2x + 5y = 40
x = 2y
Solving the system we have:
x = 8.9
y = 4.4
Answer:
The maximum number of pillowcases she could have purchased is:
x = 8 (spent less than $ 40)

If x represents an even number, which expression represents an odd number?

Sauron [17]

Test the choices !
Pick an even number, and see what each choice does to it.

Let's start with, say, 6 .
We'll try each choice, and see which one produces an odd number:

a). 6 to the 2nd power. . . . . . 6 x 6 = 36. That's not an odd number.

b). 6 + 3 = 9 This could be it. 9 is odd. We'll save this one.

c). 3·6 = 18. That's not an odd number.

d). 6/3 = 2. That's not an odd number.

The only one that gave us an odd number is (b).
