The diagrams below represent rock layers found in two different locations by two different scientists. The scientist at location X used letters to label his rock layers, while the scientist at location Y used roman numerals to label her layers. Examine these diagrams and then answer the question that follows.The scientists both used the same colors and patterns to represent different types of rocks. They also used the same set of black-and-white symbols to represent specific types of fossils in the layers. By correlating layers based on fossils and rock types, the two scientists have discovered that certain rock layers are present in both locations.Which layers are the same?

Which expression is equivalent to 5x + 4 - x - 2a. 4x + 2
b. 4 + 4x
c. 4x
d. 4x + 6

Answers

A: 4x+2 , this is the answer because  5x+4-x-2 = 4x+2 = bring all the way down,
                                                             +2      +2

Please help my answer is c, is this right!

Answers

I'm not sure how you got c but the way you would solve this is for every x on the line plot you would add that amount. You don't need to worry about 0 because 0 is nothing.
There are 3 X's at 1/4 so you would add 1/4+1/4+1/4=3/4. There are 2 X's at 1/2 so you would add 1/2+1/2=1. There are 2 X's at 3/4 so you would add 3/4+3/4=1.5. There is 1 X at 1 so it would just be 1. Then add all those together 3/4+1+1.5+1=4.25 or you could just add each X as you come across it on the number line like so:
0.25 + 0.25 + 0.25 + 0.5 + 0.5 + 0.75 + 0.75 + 1 = 4.25

Give three solutions of the inequality
6 − 11x < 61

Answers

Any positive number can be substituted as x to solve the inequality.
Ex. 6-11x, x=5, 6-11(5)= 6-55, which is -49. 61 is greater than -49. Substitute any other positive numbers and they will work also.

Which statement is true?A: (11)/(20) = (4)/(7)
B: (11)/(20)(4)/(7)
C: (11)/(20) < (4)/(7)
D: (11)/(20) > (4)/(7)

Answers

(11)/(20)=(11\cdot7)/(20\cdot7)=(77)/(140)\n\n(4)/(7)=(4\cdot20)/(7\cdot20)=(80)/(140)\n\n(77)/(140) < (80)/(140)\to(11)/(20) < (4)/(7)\to\boxed{C.}
