2(1 - 3r) + 3(r + 2) > 5

Answers

Answer: r < 1

Step-by-step explanation:

1. 2(1 - 3r) + 3(r + 2)  >5

2. Distribute:   2 - 6r + 3r + 6  > 5

3. Combine like terms. I'll put these in parentheses so you can see them better:   (2 + 6) + (-6r + 3r) -> 8 -3r > 5

4. Isolate the variable(r) by subtracting 8 from both sides: -3r > -3

5. Isolate the variable(r) by dividing. Keep in mind the sign flips when multiplying or dividing by a negative: r < 1

6. Answer analysis, if you don't understand: The answer is r < 1. Meaning r is anything smaller than 1, so 0 and all the negative numbers.

Hank has cards that are 8 inches by 4 inches. a stack of these cards fits inside a Box that is 8 inches long 4 inches deep 4 inches high. the cards use up to 32 cubic inches of volume how tall is the stack of cards? What percent of the Box's volume is taken up by the cards?

Answers

32 cubic inches of cards
V=area of bsase times height
area of base=4*8=32
32=32*height
1=height
card stack is 1 inch high

find volume of box
v=8*4*4=128

32 cubic inches of cards
percent means parts out of 100
x%=x/100
32/128=0.25/1
0.25/1 times 100/100=25/100=25%

answer is 25%


1 inch tall
25% taken up
