Christopher needs to create so that his time spent will be the same as his current time, the equation could be: 2.4x = 1.2x + 15
Answer: Approximately 13 ft
Step-by-step explanation: For this, you have to do the Pythagorean Theorem. First set up an equation. That equation is a squared+b squared=c squared. Next, plug in values. A=12 and b=4. The equation becomes 12 squared+4 squared=c squared. Do the math and you'll get 144+16=c squared. Add and get 160=c squared. Then do the square root of both sides and you'll get 12.649=c. Round to nearest whole number to get approximately 13 ft. You can also represent it as the square root symbol with 160 inside, like this(√160).
Answer:
14×6=84 and 6×14=84, 84+6=90
Answer:
d. -11+7
Step-by-step explanation:
two negatives make a positive.
i hope this helps :)
Just make the equations equal to each other. -0.5x+5=3x-2. Solve for x and find that it is 2, via simple algebra. Since you know x is 2, sub it in in either equation to find y. y should be 4. So the point that fits both equation is (2,4). This shows that the two graphs of these lines will intersect at this exact point.
If you were to graph these two lines, you ould see that the point of intersection is at (2,4) like we solved for.
