You can solve this two ways:
One is by substituting in the numbers until you get 15=15.
6(0)-9=15
0-9=15
-9=15
6(1)-9=15
6-9=15
-3=15
6(2)-9=15
12-9=15
3=15
6(3)-9=15
18-9=15
9=15
6(4)-9=15
24-9=15
15=15
Solution is x=4
or you can find the value of x
by first adding 9 to both sides to get x by itself
6x-9=15
6x=24
Then divide by 6
x=4
Answer:
430
Step-by-step explanation:
To find the area, use the area for a parallelogram formula:
A = bh, where A is the area, b is the length of the base, and c is the height of the parallelogram.
Next, substitute the values of the base and height:
A = 20in. * 21.5 in.
Finally, simplify the multiplication:
A = 430
Answer:
5 cm
Step-by-step explanation:
Area = length x width
40 = 8 x w
40/8 = w
5 = w
