There’s an invisible 1 in front of the minus sign and an invisible 1 in front of the variable.

-1(r+4)=-3 —> -1 times 1r = -1r. -1 times 4 = -4
Multiply inside the parentheses.

-1r-4=-3

Now add 4 to both sides.

-1r-4=-3
+4=+4
-1r = 1
Now divide

R= -1

Answer:

D is the correct answer.

Step-by-step explanation:

<em>Step 1: Write the data</em>

Total number of songs = 100

Total ratio = 1

Total percentage = 100%

Ratio of jazz songs = 1/4

Percentage of jazz songs = 1/4 x 100 = 25%

Ratio of pop songs = 1 - 1/4 = 3/4

Percentage of pop songs = 3/4 x 100 = 75%

<em>Step 2: Match the statement.</em>

The correct statement is D; 25% are Julian's songs are jazz because 1/4 = 25/100 and 75% are pop because 3/4 = 75/100.

Which symbol replaces ? to make the statement true?
padilas [110]
4*16-16 ? 4[24-2(4+8)]
Since 16+16+16+16 is the same as 4*16 I'l just make it 3*16 (because you minus 16 from it)

3*16 ? 4[24-2(4+8)]
48 ? 4[24-2(4+8)]
48 ? 4[24-2*12]
49 ? 4(24-24)
49 ? 4*0
49 ? 0
49>0

So it is a >

Hope this helps :)
