Step-by-step explanation:
<u>Step 1: Define systems</u>
y = x - 2
-2x + 3y = -1
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute in <em>y</em>: -2x + 3(x - 2) = -1
- Distribute 3: -2x + 3x - 6 = -1
- Combine like terms: x - 6 = -1
- Isolate <em>x</em>: x = 5
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define equation: y = x - 2
- Substitute in <em>x</em>: y = 5 - 2
- Subtract: y = 3
3=(1.10)^t
Log(3)=t*log(1.10)
t=log(3)÷log(1.10)
t=11.5 years
⅝ of the votes were for blue. That leaves ⅜ of the votes remaining. 5/9 of the remaining ⅜ votes were for green, so you multiply 5/9 x ⅜ = 15/72 votes for green. ⅝ of the votes were for blue, so you can multiply the fraction by 9/9 to get 45/72. So 45/72 votes were for blue, and 15/72 votes were for green. That leaves 12/72 votes remaining, which were for red. Since the question says 48 votes out of the total number of votes were for red, this means 48/v = 12/72 (v = the total number of votes). Cross multiply and solve for v to get v = 288. The fraction for blue is ⅝, so you can say x/288 = ⅝ (x = the number of votes for blue). Cross multiply and solve for x to get x = 180 votes for blue.
