What digit does b represent? what digit does c represent?

B=5, C=3

Step-by-step explanation:

Adding two 3-digits number you get 4-digit number, then Q=1 (Q cannot be greater than 1, because 4 + B cannot be greater than 20) and B ≥ 5 (if B < 5, then 4 + B cannot give 2-digits sum).

If B > 5, then the sum will end in digit that is greater than 1 ( 6+6=12 or 6+6+1=13, 7+7=14 or 7+7+1=15, 8+8=16 or 8+8+1=17, 9+9=18 or 9+9+1=19). Here note that B cannot equal to 0, because 4 + B must be 2-digits number.

Thus, B = 5, then P=0. If P = 0, then C = 3 and you get

453 + 557 = 1010.

step-by-step explanation:

the options are kind of confusing. i can tell you what i see going on here when i look at the graph.

the class and exam medians are closely related, and it looks like the low outlier on the exam did pull the median lower. [tex][/tex]

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.
