To find how much older Leo is than John, we need to first assign our variables. In this case, let's say that x = Leo, y = Karla, and z = John. Now, let us turn words into numbers.
x = 2y
z = y - 7
Next, we need to create an equation for their combined ages. This is what the equation should look like:
x + y + z = 37
Now, just substitute the expressions we found for x and z. This is what we get:
2y + y + (y - 7) = 37
Solve for y:
2y + y + y - 7 = 37
4y - 7 = 37
4y = 44
y = 11
So now we have the value for y, which is Kayla's age. Therefore, just substitute the value for y back into the equations for x and z.
x = 2(y) => x = 2(11) => x = 22
z = y - 7 => z = 11 - 7 => z = 4
Now that we have the values for x, y, and z, all we need to do now is reassign them back to their respective names. Our final answer will be: John is 18 years older than Leo. The answer to your query would be E) 18. Hope this helps and have a nice day!
The equation is always y=mx+b so find where the x,y intercepts are between ur points
Answer:
Yes.
Step-by-step explanation:
If you graph it you can see that they all the points match up to the perfect right triangle. You may have to rotate it to see it though. Point Z is the angle of the triangle that is the corner of the 90 degree triangle.
Answer:
Example: 45+45
Example: 100+80
Step-by-step explanation:
Any two angles that sum to 90 degrees will create a set of complementary angles, and any two angles that sum to 180 degrees will create a set of supplementary angles.
Well if he starts at 7:00 and talks a walk for 1 1/2 hours you would first add the full hour to 7
8:00
Then add the 30 minutes or the half hour
8:30
After that, add the other full hour that he took to get ready
9:30
Then add the additional 5 mins it took for him to get ready
9:45
Hope this helps!
