Step-by-step explanation:
.8 x 20 =16
<span>-28x²-12x = -4x(7x+3) the first one is answer</span>
Fraction would be 30/100 and decinal would be .30 and ratio would be 30/100
The second i think you did good
Step-by-step explanation:
right.
and therefore c is in this case the name of the variable in the equation (or function).
add on.
ah, do you mean (and does this strange problem description mean) that you want the reverse formula : to get C out of F ?
in that case
F = 1.8c + 32 = 9/5 × c + 32
F - 32 = 9/5 × c
5/9 × (F - 32) = c
or
c = 5/9 × (F - 32)
that's it.
