8x-16-3x=5x-15-1
5x-16=5x-16
X can be equal to anything.
The area of a rectangle is as follows...
Area = Base x Height
Base is given to be 3h + 5 and height is given to be 2h
Area = (3h+5)(2h) = 6h^2 + 10h which is none of the answers listed.
Answer:
x = 23/16
Step-by-step explanation:
x + 1/16 = 3/2
Get a common denominator
x + 1/16 = 3/2 *8/8
x + 1/16 = 24/16
Subtract 1/16 from each side
x+1/16 -1/16 = 24/16 -1/16
x = 23/16
Answer:
2.(b) w= 3
3. x= -3 or x= 3
Step-by-step explanation:
2.(b) <u>Method 1:</u>
Simplify:
×5 on both sides:
Expand:
Bring constants to 1 side, w terms to the other:
Simplify:
Divide both sides by 3:
<u>Method 2:</u>
Multiply by 5 throughout:
Expand:
Simplify:
+9 on both sides:
-4w on both sides:
Simplify:
Divide by 3 on both sides:
3.
Multiply by 3x on both sides:
Expand:
Simplify:
Divide by 6 on both sides:
-9 on both sides:
Factorise:
*Since a²-b²= (a +b)(a -b),
Thus,
x +3= 0 or x -3= 0
x= -3 or x= 3
