13 x 13 x 13 = 2197
I know that 12 times 12 is 144 so if I go 1 digit higher I would do 13 times 13 which is 169. 169 is in between 150 and 180.
5 x 2 x 13 x 12 1) Multiply 5 and 2, You get 10 2) Multiply the result you got before in step 1 which is 10 by 13. I will let you figure it out. 3) Multiply what you got in step 2 by 12. I will let you figure it out. The product you get in this third step is the answer. Try it. You can do it. Good luck!
13. 13 goes into 13 once, into 52 four times, and into 130 ten times.
let's denote the first number with x, and the second number with y. So, 8x + 5y = -13 x + y = 1 y = 1 - x substitute 1 - x for y at the first equation; 8x + 5(1 - x) = -13 8x + 5 - 5x = -13 3x + 5 = -13 subtract 5 to both sides; 3x = -18 divide by 3 to both sides; x = -6 y = 1 - x substitute -6 for x ; y = 1 -(-6) y = 1 + 6 = 7 Thus the numbers are -6 and 7. Check.
1 times 13 = 13 and 1 times 41 = 41
13/32 13 16th (or 13/16) divided by two is the same as 13/16 times 1/2 13/16 times 1/2 is the same as (13 times 1)/(16 times 2) (13 times 1)/(16 times 2) is 13/32
1/2 x 13/16 is 13/32
It is: 1*13 = 13
13 x 1 x 2 = 26
It is: 1*13 = 13
0.4615 times.
That's 13.
It is: 1 times 13 = 13
13 x 1
1 x13 =13
