Answer
X= 9+3y/2
Y=-6+2x/3
hope that helps
Depending what your solving X for what type of equation because it has different rules
Not sure I'm right but:
If the bar weighs 9.25 ounces and 65% of the bar is gold, you'd do 65% of 9.25. So the answer would be <span>65% of 9.25= 6.0125</span>
When you know your equation f(x) and they want you to find f(-4), it means that they want to know what f(x) is worth when x=-4
Therefore, you only need to plug in you x in the equation
f(x)=5x-2
f(-4)=5(-4)-2
=-20-2
=-22 (B)
Answer:
Step-by-step explanation:
<u>Given the equation: </u>
- E - weekly total, g- number of hours at gas station, t- number of hours at toy store.
<u>Substitute given values into equation and solve for the missing one:</u>
- 219.75 = 9.25g + 10.5*13
- 219.75 = 9.25g + 136.5
- 9.25g = 219.75 - 136.5
- 9.25g = 83.25
- g = 83.25/9.25
- g = 9
