Answer:
x= -3
Step-by-step explanation:
<u>3x-1= -10</u>
<u> +1 +1</u>
3x=-9 = -3
Step-by-step explanation:
10 is the value of A ......
Answer:
1089
Step-by-step explanation:
The original number is A0CD, We have that DC0A = 9 x A0CD.
If A =1, then D = 9 and we have:
9C01 = 9 x 10C9
In order for this expression to be true, the following must also be true:
(C x 9) + 8 must be divisible by 10, which means that C x 9 must end in a 2.
The only multiple of 9 (from 9 to 81) that ends in a 2 is 72.
72 = 9 x 8.
Therefore, C must be 8 and the original number is 1089. Multiply it by 9 to check the answer:
1089 x 9 = 9,081
Therefore, 1089 is correct.
Volume (V) is (=) Length (L) times (x) Width (W) times (x) Height (H) so V = L x V x H.
Add the variables to the equation.
V = 24 x 10 x 13
Solve
V = 3120
So the volume of the gift box is 3120 cm
8 in 2.408 is closer to 10, so you round 2.408 to 2.41
