Answer:
1/4
Step-by-step explanation:
So, we can create this representation of a in relation with b, since we know a is smaller than b by 1/5 of b, we can say that a is equal to 4/5 of b, right?
To invert the ratio, we need to isolate B, so we multiply both sides of the equation by 5/4
So, we have b being 1/4 bigger than a.
Answer:
D
Step-by-step explanation:
In a 30-60-90 triangle, if the short leg is x, then the long leg is x√3, and the hypotenuse is 2x.
Here, the hypotenuse is 10. So the short leg is:
10 = 2x
x = 5
If the short leg is 5, then the long leg is 5√3.
-2a-9=6a+15
Move 6a to the other side. Sign changs from +6a to -6a.
-2a-6a-9=6a-6a+15
-2a-6a-9=15
-8a-9=15
Move -9 to the other side. Sign changes from -9 to +9.
-8a-9+9=15+9
-8a=15+9
-8a=24
Divide both sides by -8
-8a/-8=24/-8
a=-3
Answer: a=-3
