<span>2x - 3y - z
Substitute the variables for the numbers provided for them
</span><span>2(-2) - 3(3) - (-2)
Multiply 2 by -2
-4 - 3(3) - (-2)
Multiply -3 by 3
-4 - 9 - (-2)
Subtract 9 from -4
-13 - (-2)
Convert Subtract -2 from -13. It would be the same as adding 2 to -13.
Final Answer: -11</span>
You would need 27 more dollars because f(x)=7x+2 plug in the 5 in x’s spot and you get 37 and so subtract it from 10 to get 27
Answer:
1448 mL
Step-by-step explanation:
The mass is the same.
Formula
m = d*V
Givens
<em><u>Olive Oil</u></em>
d = 0.92 grams / mL
V = ??
<em><u>Gasoline</u></em>
d = 0.74 grams / mL
V = 1.8 L = 1.8 L * (1000 ml / L)
V = 1800 mL
Solution
0.74 * 1800 mL = 0.92 * x Divide both sides by 0.92
0.74/0.92 * 1800 mL = 0.92 *x / 0.92 Combine the left
0.8043 * 1800 mL = x
x = 1448 mL
The volume of Olive Oil needed is 1448 mL
