Answer:
$19.50
Step-by-step explanation:
We can turn these into equations by making the shirts 's' and the ties 't'.
4s+2t=95 and 3s+3t=84
Now we can solve the system of equations with substitution.
Answer:
I'm not sure but the last one I think is wroght
Step-by-step explanation:
Let the first number be <em>x</em>
Let the second number be <em>y</em>
<em>x</em> = y - 9
3x = 4y + 12
3x - 4y = 12
3(y - 9) - 4y = 12
3y -4y - 27 = 12
-y = 12 + 27
-y = 39
y = -39
x = y - 9
x = -39 - 9 = -48
Answer:
x = 0
Step-by-step explanation:
If one were to fold this figure in half over the line x = 0, then one would end up with a single figure, with no overhang. Hence x = 0 is the line of symmetry. Note; x = 0, can also be called the y-axis.
