20 questions. Your friend would have to get 12/20 questions right and you would get 11/20 questions right. 12 and 11 don’t have any common denominators so that’s your answer. Hope this helps!
5x-12=3x
Let's solve your equation step-by-step.
<span><span><span>5x</span>−12</span>=<span>3x
</span></span>Step 1: Subtract 3x from both sides.
<span><span><span><span>5x</span>−12</span>−<span>3x</span></span>=<span><span>3x</span>−<span>3x
</span></span></span><span><span><span>2x</span>−12</span>=0
</span>Step 2: Add 12 to both sides.
<span><span><span><span>2x</span>−12</span>+12</span>=<span>0+12
</span></span><span><span>2x</span>=12
</span>Step 3: Divide both sides by 2.
<span><span><span>2x/</span>2</span>=<span>12/2
</span></span><span>x=<span>6</span></span>
Answer:
Jack is incorrect. The correct answer is 2
Step-by-step explanation:
The question is given as:
4x-24 / (y+w) where x=5, y=3 and w= -5
Substitute values of x, y and w in the equation as;
4*5 - 24 / (3+-5)
20 - 24 / (-2)
-4 / -2 = 2
Jack's answer is 7 which is wrong. The correct answer is 2
2 is correct because you have substituted the real values of x,y and w in the expression and performed the operation right.
