Answer:
m = -10
Step-by-step explanation:
0.61m - 1.51m = 9
-0.90m = 9
mutiply both sides by -1.111111111111, twelve 1's after the decimal point
also to find what number u need to multiply to make -0.9m to m, divide 0.9 by 1 and that equals 1.111111111111 so yea a lot of ones haha
m = -10
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)
1. 3/5
2. 15
3. 1/15
4. 1 2/3
It is substitution. Because you are substituting 3=y into x+5=3
Mean is average
so we have 4 numbers
sum them then divide by 4
(32+31+37+44)=144
divide by 4
144/4=36
answer is C
