Nadia buys boxes of crackers that each has the same cost c. She represents the cost of 6 boxes of cheese crackers, 5 boxes of poppy seed crackers, and 2 boxes of plain crackers using the expression
6c+5c+2c. What equivalent expression can represent the cost?
A.6x5x2xc
B.13c
C.(6=5)2c
D.14c

B.

Step-by-step explanation:

6c+5c+2c equals 13c so therefore B. is the equivalent expression

B. 13c

Step-by-step explanation:

Basically you should combine like terms, meaning add the numbers with the same variable! So since they all have the same variables add 6+5+2=13 and then add the variable to the end, which makes the answer 13c

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
