Answer:
105 girls
Step-by-step explanation:
the ratio is 5:3 equal to 168. You need to multiply the ratio with 21 to make it equal
Find 60% of 65 then add it to 65:
0.6 * 65 = 39
Now add it to 65:
39 + 65 = 104
So she's selling camera's for $104 each.
By expanding D it is clear that it is the factored form of 2/3x + 4
as 2/3x + 4 = 2/3x + 4*3/3
= 2/3x + (2*3)*(2/3). ( rearranging terms)
=2/3( x+ 2*3). ( taking 2*3 common)
=2/3( x + 6)
which is option D
hope it helped ^_^
