The ratio 2 : 3 is the same as the ratio of 6 : 15. 2.) This is an example of scaling down by a scale factor of 5. The ratio 8 to 11 is the same as the ratio 40 : 55.
Y= 2.75 add 3 to both sides and divide by 2 (2y - 3 = 2.5)
x= 4.5 subtract 8 from both sides and divide by 6 (6x + 8 = 35)
It isn't A because there isn't a decimal in the hundredths.
It isn't B because it doesn't have a decimal coefficient on the left side: that means it could be C or D, to find out we should find what x is in C:
0.5x-5=0.15x+2
0.5x=0.15x+7
0.35x=7
Divide both sides by 7
0.05x=1
Now multiply both sides by 20:
x=20
That means it must be D, let's make sure:
0.6x-3=0.28x+5
0.6=0.28x+8
0.32x=8
Divide both sides by 8:
0.04x=1
Now multiply both sides by 25:
x=25
So the answer is D

(X+6)(x-2)
X=-6
X=2

Answer:
The answer to your question is 0 < x ≤ 3
Step-by-step explanation:
To write this inequality we must consider
- The value of the borders, for this inequality the borders are 0 and 3.
-The kind of border - if it is an open point, we will use the symbol <
- if it is a close c point, we will use the symbol ≤
-The inequality for this problem will be
0 < x ≤ 3
