Answer:
823*53=43619
Step-by-step explanation:
I use the following method when it comes about products of big numbers
I grab the longer and put on the first line, below I put the smallest number
823
x 53
Now just is matter of performing 2 products
823*3 which goes in a line below the prior
823*5 which goes in a line below the prior, and put an extra zero to the right
At the end of it, just sum the terms from two lines above
823*3= 2469
823*5=4115 (with no extra zero)
So
823
x 53
-------
2469
41150 (with extra zero)
---------
43619
Answer:
so u need to measure it with a ruler
Step-by-step explanation:
ok so measure each side
then if all the sides have the same length, then it is an equilateral triangle
if only two of the sides are equal, then it is isoceles
and if all the sides have different lengths, then it is scalene
Answer:
Step-by-step explanation:
z = 3
2y + z = 1
2y + 3 = 1 {substituting z =3}
2y = 1 -3
2y = -2
y = - 2/2
y = -1
2x +3y +2z = 13
2x + 3 * (-1) + 2*3 = 13 { {substituting z =3} and y = -1}
2x -3 + 6 =13
2x + 3 = 13
2x = 13 - 3
2x= 10
x = 10/2
x = 5
Answer:
the answer to this question is 2.4b
160 = 2 x 2 x 2 x 2 x 2 x 5 = 2^5 x 5
243 = 3 x 3 x 3 x 3 x 3 = 3^5
So
(160 * 243)^1/5
= 5th root of (160 * 243)
= 5th root of (2^5 * 5 * 3^5)
= 2 * 3 * (5th root of 5)
= 6 * (5th root of 5)
Answer is D. 6 * (5th root of 5)
