Answer:
16.66
Step-by-step explanation:
1) eliminate constant first by performing the opposite operation:
0.24a+0.5-0.5=4.5-0.5
0.24a=4.0
divide both sides by 0.24
a=16.66

Hope this helped! :)
13*18
x*y =234
x+y=31
we know the 2 # have to be double digits and both between 10-20
find 2 values that * to a number that ends in 4. Those are the ones value
1*4 11 and 14
2*2 12 and 12
3*8 13 and 18
only 13 and 18 add up to 31 and multiply to 234
