2)
32/28=w/7
you cross multiply one denominator by the other numerator so
32(7)=(28)(w)
simplify
224=28w
divide 28 from both sides to get w alone
8=w

4)
36/21=24/s
cross multiply just like in the last problem
(36)(s)=(21)(24)
simplify
36s=504
divide 36 to get s alone and essentially solve for s
S=14

Which expression is equivalent to − 5 6 (x − 1 2 y + 12)? A) 5 6 x + 5 12 y − 10 B) 5 6 x + 5 12 y + 12 C) − 5 6 x + 5 12 y − 10

navik [9.2K]

Answer:

Option A - $-\frac{5}{6}(x-\frac{1}{2}y+12)=-\frac{5}{6}x+\frac{5}{12}y-10$

Step-by-step explanation:

Given : Expression $-\frac{5}{6}(x-\frac{1}{2}y+12)$

To find : Which expression is equivalent to given expression ?

Solution :

Expression $-\frac{5}{6}(x-\frac{1}{2}y+12)$

Applying distributive property, $a(b+c)=ab+ac$

$-\frac{5}{6}(x-\frac{1}{2}y+12)=-\frac{5}{6}x-(-\frac{5}{6})(\frac{1}{2}y)+(-\frac{5}{6})(12)$

$-\frac{5}{6}(x-\frac{1}{2}y+12)=-\frac{5}{6}x+\frac{5}{12}y-10$

Therefore, option A is correct.

The value of the 4th term is 80. The sequence is doubling at each step. (Please answer this is due tomorrow)

Lyrx [107]

The value of the 5th term of the geometric sequence is of 160.

<h3>What is a geometric sequence?</h3>

A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.

The nth term of a geometric sequence is given by:

$a_n = a_1q^{n-1}$

In which $a_1$ is the first term.

We already have the 4th term and the common ratio, hence the 5th term is given by:

80 x 2 = 160.

The value of the 5th term of the geometric sequence is of 160.
