Answer:
The correct answer is that s > 4
Step-by-step explanation:
In order to find this, we can stick the -7 in for d and then solve the equation. This will leave us with a value for s.
d + s > -3
-7 + s > -3
s > 4
You just told us that 't' is the tax, and 'c' is the cost of the item.
We know it's not the 'equals' sign (=), so the only thing left
that it could be is the 0.07 .
To convert 0.63 to a fraction, do the following:
Answer:
s = 6 + e
s + e = 28
We can use this system of equations to find the exact values of s and e.
We have a current value of s, so we can find the exact value of e now.
e + e + 6 = 28
<em><u>Combine like terms.</u></em>
2e + 6 = 28
<em><u>Subtract both sides by 6.</u></em>
2e = 22
<em><u>Divide both sides by 2.</u></em>
e = 11
Now we have an exact value of e, and can solve for the value of s.
s = 6 + 11
s = 17
