2x = 8 - 5y
x = 8/2 - 5y/2
x = 4 - 2.5 y
or
x = 4 - 5/2 y

I got my answer from quizlet
Answer:
None of the expressions is equal to 0.7 x 0.41.
Step-by-step explanation:
Given that 0.7 x 0.41 is equal to 0.287, to determine which options are equal to said operation, the calculations set out for each of them must be performed:
A. 7,100 × 41100 = 291,810,000
B. 710 × 41100 = 29,181,000
C. 7100 × 4110 = 29,181,000
D. 710 × 4110 = 2,918,100
E. 70100 × 41100 = 2,918,100,000
Therefore, looking at all the results produced by the predisposed calculations, it is evident that none of the expressions is equal to 0.7 x 0.41.
Answer:
0.3x= 0.01x+2.9 -->
--> -0.01x -0.01x -->
--> 0.29x= 2.9 -->
--> /0.29 /0.29 -->
--> x=10
Step-by-step explanation:
1: subtract 0.01x from both sides
2: divide your answer (0.29) on both sides
3. you answer is now whatever x is (10)
Answer:
Is it 2160?
Step-by-step explanation:
This is permutation
Imagine □□□□□, each □ represents a digit
For the 1st □, there are 6 choices, since "0" cannot be the first digit, or else it is not a 5-digit number
For the 2nd □, there are 6 choices (1 out of the 7 number is already used)
For the 3rd □, there are 5 choices (2 out of 7 numbers are used)
And so on.....
Therefore,
6×6×5×4×3 = 2160
