C. Divide the numerator by the denominator.
Supplementary = 180 degrees...
A + B = 180
3x + 12 + 7x + 38 = 180
10x + 50 = 180
10 x = 130
x = 13
To find the A just substitute x in...
3 ( 13) + 12
A = 51
To check substitute the x..
A + B = 180
3(13) + 12 + 7(13) + 38 = 180
51 + 129 = 180
180 = 180
Come on this is really easy..500
The answer would be 0.975 because 9.75/10=0.975
Answer:
cost to afford to bring these calculators is $8.4
markup on retail = 5.6
Step-by-step explanation:
given data
selling price = $14
mark up on selling = 40% = 40/100 = 0.40
to find out
What cost can Mike afford to bring these calculators
solution
we calculate markup on retail that is mark up on selling of selling price
markup on retail = 0.40 × 14
markup on retail = 5.6
so
cost to afford to bring these calculators = 14 - 5.6
cost to afford to bring these calculators is $8.4
