Answer:
set middle number=x
then left side number=x-1
and right side number=x+1
(x-1)+x+(x+1)＝30
3x=30
x=10
x-1=9
x+1=11
numbers are 9,10,11
Answer:
In the area formula, there are two dimensions that are multiplied, base and height. So, the units are also multiplied. Inches times inches is inches squared. Also, area is a measurement that counts how many squares fit inside of a shape, so it makes sense that the units are described as squared.
Step-by-step explanation:
Answer:
y = x -3
Step-by-step explanation:
From the graph we see the line goes from point (0, -3) to point ( 3, 0), so we can find the slope as m= rise ( go up 3) / run ( go to the right 3) = 3/ 3 = 1
From the graph we can also see the y-intercept ( where the line intersects the y axis is at b = -3
The general equation of the line is y= mx+ b
Our line's equation is y = x -3, because m=1 and b= -3
Answer:
x=0.5
Step-by-step explanation:
2x+y= -2
and
4x+y= -8 so...
2x+y= -2 = 4x+y= -8
2x+4x= 6x
y+y=2y
-2+-8= -10
6x+2y= -10
2y- -10= 12
6x=12
6/12=0.5
x=0.5
