Step-by-step explanation:
x^2 + 10x = -25
x^2 + 10x + 25 = 0
（x+5)^2=0
x=－5
5/10 + 1/3
15/30 + 10/30 = 25/30 = 5/6
Answer : 5/6 in its simplified form

Answer:
2,250,000 km
Step-by-step explanation:
From the above question our scale is given as:
1 m : 250000km
We are trying to find the distance between two villages which is 9m apart in kilometers
Hence
1 m : 250000km
= 1 m = 250000km
9m = x km
Cross Multiply
x km = 9 × 250,000km
x km = 2,250,000 km
Answer:
Alma is correct.
Step-by-step explanation:
It is a greater change to roll a 1 or a 5 then both. The chances of rolling both can be a bit high but it is also an easier chance that you will roll one of the other.
If you have 2 dice. To roll a 1 and a 5 you only get one change. But to roll one or the other you have 2 different chances. Therefore if you were to roll both dice you have a higher chance to roll a 1 or a 5 with having two dice.
