Answer:
20+9=29, 11+18=29, 23+6=29, 9 2/3 * 3 =29, 7 1/4 * 4 =29, 3 2/9 * 9 =29
Step-by-step explanation:
I'm not sure if you mean by multiplying or adding, so I'll give you both.
20+9=29
11+18=29
23+6=29
9 2/3 * 3 =29
7 1/4 * 4 =29
3 2/9 * 9 =29
Not sure if that helped... If I didn't help, can you specify please?
Answer:
One num = 6x = 6 x 70 = 420
Second= 4x = 4 x 70 = 280
Step-by-step explanation:
6x + 4x = 700
10x = 700
x = 700/10 = 70
One num = 6x = 6 x 70 = 420
Second= 4x = 4 x 70 = 280
I hope im right!
Answer:
Elimination isn't exactly the easiest for this situation. But since the equations are in the same form and not solved for the same variable, I would go with elimination. (If they were solved for the same variable, I would go with substitution.) It would require me to make a manipulation on both equations.
I would multiply first equation by 5 and second equation by -2. The reason I would do this is because the y's would have opposite coefficients and when you add opposites you get 0.
The new set of equations would look like this:
20x+10y=45
-14x-10y=2
But I will slope here since we aren't asked to solve it.
Some texts use the term linear combination instead of elimination. They are the same.
If he is biking at the same rate he will bike 28 miles after 4 hours.
I hope this helps c:
