Step-by-step explanation:
For number 3 thats all i could get
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.

There a number of methods in solving a system of equations. These methods are the substitution method, solving by graphing, gaussian elimination and by elimination method. For this case, we use the substitution method. To do this, we write one of the equation in a way where one variable is left on one side. We do as follows:
<span>−0.9x+0.5y=3.9
0.5y = 3.9 + 0.9x
y = 3.9/0.5 + 0.9x/0.5
y = 7.8 + 1.8x
Then, we subsitute this equation to variable y in the second equation.
</span>0.4x+1.5(7.8 + 1.8x)=−6.9
Then, we solve for x
0.4x+1.5(7.8 + 1.8x)=−6.9
0.4x+11.7 + 2.7x=−6.9
3.1x = -18.6
x = -6
We substitute this value of x, to the first equation to solve for y
y = 7.8 + 1.8x
y = 7.8 + 1.8(-6)
y = -3
