Answer:
18+2x>_0
18/2 + 2x/2
x= 9
Step-by-step explanation:
first take the 2x to the other side which will automatically change from - to + and then divide both 18 and 2x by 2

Answer:
B. 80.2 square inches
Step-by-step explanation:
This figure is a composite figure made up of two rectangles (see attachment).
The area of a rectangle is denoted by: A = lw, where l is the length and w is the width.
In the top rectangle, the length is 3 and the width is 10.2, so A = 3 * 10.2 = 30.6 square inches.
The length of the bottom rectangle is 8 and the width is 6.2, so the area is A = 8 * 6.2 = 49.6 square inches.
Add these together: 30.6 + 49.6 = 80.2 square inches.
Answer:
y = 1/4x-1
Step-by-step explanation:
Ok first, you need to find the slope:
0+2 = 2=1
4+4 = 8=4
Slope: 1/4
y=1/4x+b
Now you need to find the y intercept which is b. For that you can take a coordinate pair and substitute it in the equation to find b.
I will use (4,0)
0=1/4 X 4 + b
0=x+b
minus x on both sides. x=1
-1=b
Answer:
-5.66 + 4.1
Step-by-step explanation:
Whenever you subtract a negative number, it will change it to adding a positive number.
-5.66 - (-4.1) -> -5.66 + 4.1
Best of Luck!
