9514 1404 393

Answer:

  a = any positive multiple of 3

Step-by-step explanation:

You want ...

  (5 1/3)/(4/a) = whole number

  (16/3)·(a/4) = whole number

  (4a/3) = whole number

This will be the case for a = 3n, for any positive integer n.

tensa zangetsu [6.8K]

If he bought 4 hats for $5 each and he spent a total of $44, he spent $44 - $20 in shirts.

44 - 20 = 24

2 shirts for $24 is 1 for 12

$12 for each shirt

Factor completely 4xy − 7x + 20y − 35.
kati45 [8]

Answer:

A) (x+5)(4y-7)

Step-by-step explanation:

Given expression:

4xy-7x+20y-35

To factor the given expression completely.

Solution:

In order to factor the expression, we will factor in pairs.

(4xy-7x)+(20y-35)

We will factor the G.C.F of the terms in the pairs.

G.C.F. of 4xy and 7x can be given as:

4xy=4.x.y

-7x=7.x

Thus, G.C.F. = x

G.C.F. of 20y and 35 can be given as:

20y=2\times 2 \times 5.y

35=5\times 7

Thus, G.C.F. = 5

The expression after factoring the G.C.F. pairs is given as:

x(4y-7)+5(4y-7)

Taking G.C.F. of the whole expression as (4y-7) is a common term.

(x+5)(4y-7)

The expression is completely factored.
