Answer:
Both lights flash at 1:00
Step-by-step explanation:
they flash together every 2*7=14 minutes
in 60 minutes there are 4*14=56 minutes
they flash together at 1:56
more minutes brings you to 2:00
they flash together at 2:10 (4+10=14)
that leaves 50 minutes left in the hour
they flash three times which uses up 42 minutes
this brings you to 2:52 (10+42=52)
8 more minutes brings you to 3:00
in 6 more minutes (8+6=14) it will be 3:06 and they will flash together
<h3>Option D</h3><h3>The simplified version of 7x − 4(x − 8) = 56 is 3x + 32 = 56</h3>
<em><u>Solution:</u></em>
<em><u>Given expression is:</u></em>

Use distributive property to simplify the expression
By distributive property,
a(b + c) = ab + ac
Therefore,

Combine the like terms : 7x - 4x = 3x
Therefore,

Thus option D is correct
