Determine the number of integer solutions to the inequality 2.1 +2.2 < 40 for which:
(a) x_1 and x_2 are non-negative integers.
(b) 3 \leq x_1 \leq 30 and 2 \leq x_2 \leq 20

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
