3(12)/10(12) + 7(10)/12(10) = 36/120 + 70/120
==> 18/60 + 35/60 = 53/60
They must sell 250 cameras
and 50 more cameras would be a $400 profit
Answer:
$4.83
Step-by-step explanation:
If it costs $29 for 6 hours, then it costs $29/6 or 4.83 for each hour of use.
Answer:
Rewrite the equation as 4L+4W=P.
4L+4W=P
Subtract 4L from both sides of the equation.
4W=P−4L Divide each term by 4 and simplify.
W=P/4−L
Step-by-step explanation:
Answer:
A. 149
Step-by-step explanation:
When a quadrilateral is inscribed in a circle, the sum of the opposite angles in the quadrilateral equal (180) degrees. Applying this theorem here, one can state the following:
c + 31 = 180
Inverse operations,
c + 31 = 180
c = 149
Thus, option (A) is the correct angles: ( c = 149°)
