First you take 15 and divide it by 5. That leaves you with 3. You also need to decide the x’s so you subtract the exponents (2-3=-1)
so you now have (y^10z^7)/(y^4z^10)3x^-1
Next we will divide the y’s.
Again, subtract the exponents (10-4=6) to get y^6
Now we have (3x^-1)(y^6) (z^7/z^10)
Last is z, we subtract the exponents again (7-10=-3) and get z^-3
Our answer is (3x^-1)(y^6)(z^-3)
1. a
2. 6 tps baking powder. For every 3, there is two. 3 multiplied by 2 is 6.
3. 12/8 = 1.5 seedling per minute in 70 minutes...
1.5 * 70 = 105 seedlings can be planted in 70 minutes
4. idk sorry
5. time = distance / speed
time = 300/15
time = 20 hrs
7. The ratio between 12 and 8 is 1.5, so you need to divide every other number by 1.5.
2/1.5=1.3
9/1.5=6
18/1.5=12
8. So, problem statement tells you that 1lb = 16oz and that 1oz = 28.3g. That means that 1lb = 16 * 28.3g = 452.8g
You have three items, convert their weights to grams:
1) 800g
2) 1.6lb = 1.6 * 452.8g = 724.48g
3) 30oz = 30 * 28.3g = 849g
So, sorting from greatest:
3, 2, 1, or: 30oz, 1.6lb, 800g.
9. 5•7=30

hope this helps and i hope its not confusing
Answer:
(-1,4), (-5,0), (3,10) I hope this helps.
What I did I reduced the equation and got y by itself. The new equation would be y=3/2x+11/2x. I started plugging in points. I put the equation on a graph and found those points on the graph.
5 gallons would be the right answer
2x +4y =10x-3y =12
2x +4y =12 -----eq. 1
10x-3y =12 -------eq.2
2x =12 -4y [using eq. 1]
x = (12-4y)/ 2
= 6 -2y
Now, substitute the value of x in eq. 2
10 (6-2y)-3y =10
60 -20y -3y =10
-23 y = 10 -60
y = -50 / -23
y = 50/23
Now, substitute this value of y in any equations given above
10 x-3 (50/23) =12
10x - (150/23)= 12
x= 426/230
