Hi, these equations are pretty easy actually, first thing you should know when working with variables is that you always want to leave the variable alone, let's take the third excersise for example, 12x + 2 = 146. Here you just do the opposite on the other side of the equation depending if the number is positive or negative. Since x is being multiplied by 12 you first get rid of the 2, since its positive you subtract it to 146. Now the answer should be 12x = 144. Now since you're multiplying 12 to x you just divide 12 from 144, 144/12 = 12
x = 12
Writing it as a decimal would be 3.85 you just divide it
Answer:
99 yards
Step-by-step explanation:
374 - 88 = 286
286 - 88 = 198
198/2 = 99
length = 99
Answer:
5,500
Step-by-step explanation:
I=PRT/100
Then
I = 2.5*10,000*22/100
I=#5,500
The another way to state the transformation would be 
<u>Solution:</u>
Rotation about the origin at 
: 
The term R0 means that the rotation is about the origin point. Therefore, (R0,180) means that we are rotating the figure to about the origin.
So, the transformation of the general point (x,y) would be (-x,-y) when it is rotated about the origin by an angle of .
Hence according to the representation, the expression would be 
.
