Answer:
552 in ^2
Step-by-step explanation:
formula for trapezium is h(a + b ) / 2
so.....
12(16 + 30 ) / 2 = 276
since there are two....
x 2 and..
552

If your number is x --->
-3 ≤ x ≤ 3
C.The expression is 3(p + 10). It takes 60 minutes to shape and fire 10 pots.
D.The expression is 3p + 10. It takes 40 minutes to shape and fire 10 pots.
Answer:
D. The expression is . It takes 40 minutes to shape and fire 10 pots.
Step-by-step explanation:
Let the number of pots in a batch = p
Now, one pot takes 3 minutes to get in a shape.
Then, 'p' pots will take minutes to get in a shape.
Also, it takes 10 minutes to fire one batch of pots.
Thus, the expression for the time taken to form one batch of pots =
So, when number of pots = 10 i.e. p= 10.
Time taken to fire the pots = = 30+10 = 40
That is, 'It takes 40 minutes to shape and fire 10 pots'.
Thus, option D is correct.
3x4.5
3x4+5

Answer:
Step-by-step explanation:
Three times a number x : 3x
Three times a number x increase by 4: 3x +4
Five times the number x: 5x
5x = 3x +4
Subtract 3x from both the sides.
5x - 3x = 3x +4 - 3x
2x = 4
Divide both sides by 2
2x/2 = 4/2
x=2
The number is 2
