We know, Distributive property tells: a(b + c) = ab + bc
So, 9.78(4.3x + 5.15) = 42.054x + 50.367
In short, Your Answer would be Option B
Hope this helps!
D:devaughn
S:sydney
D+S=83. First equation
D=S-9. Second equation
D-S=-9
Add 2 equations
D+S+D-S=83-9
2D=74
D=37
Devaughn is 37 years old
So
D+S=83
37+S=83
S=46
Sydney is 46 years old
Answer:
1433.09

He makes 1433.09 per minute
<span> x = 3y - 8
</span>
Plug this in for variable x in equation [2]<span>
</span><span><span> [2] 3•(3y-8) + 2y = 31
</span><span> [2] 11y = 55
</span></span>
Solve equation [2] for the variable y
<span><span> [2] 11y = 55</span>
<span> [2] y = 5</span> </span>
// By now we know this much :
<span><span> x = 3y-8</span>
<span> y = 5</span></span>
<span>// Use the y value to solve for x
</span>
<span> x = 3(5)-8 = 7 </span>Solution :<span><span> {x,y} = {7,5}</span>
Processing ends successfully</span>
