3/10 = 9/30 as an equivalent fraction.
Brainliest please?
1) and 4) are discrete as values can only realistically be whole numbers
<span>2), 3) and 5) are continuous as values are measurements that are rounded to a certain degree of accuracy. hope this helps

Answer:
x = 10
Step-by-step explanation:
1) Subtract x from both sides.
4x − x = 30
2) Simplify 4−x to 3x
3x = 30
3) Divide both sides by 3
x = 
4) Simplify to 10
x = 10
Area:
The expression for area would be length x width, therefore the expression would be (3x + 1)(2x -7)
Perimeter:
There are many expressions for perimeter. Here are some of them:
Length + width + length + width
2length + 2width
2(length + width)
Let's use the first one, for example. The expression would be (3x + 1) + (2x - 7) + (3x + 1) + (2x -7).
4-(x+2)<-3(x+4)
4-x-2<-3x-12
2-x<-3x-12
-x+3x<-12-2
2x<-14
x<-7
