I just realized I forgot a whole unit we did this year, but a(n)=5n-12
is the explicit form if that helps at all
Combine like terms
c+5.3=0.6
Subtract 5.3 from both sides
c=-4.7
Answer:
0 and 10 for this if im wrong sorry.
Step-by-step explanation:
use unitary method
for 5 it costs 330p
so for 1 choc it will cost 330/5
to get 9,
(330/5) =66
66 multiplied by 9 =594
therefore 9 will cost 594p
Answer:
50
Step-by-step explanation:
Fastest method for calculating 34 is 68 percent of what number. Assume the unknown value is 'Y' 34 = 68% x Y. 34 = 68 / 100 x Y Multiplying both sides by 100 and dividing both sides of the equation by 68 we will arrive at: Y = 3 x 100 / 68. Y = 50%. Answer: 34 is 68 percent of 50
