Just multiply your numbers then there is hour answer
The ratios 84/105 and 128/160 are proportional
<u>Solution:</u>
Given, two ratios are
and 
We have to give two different reasons to support the answer.
<em><u>Reason 1:</u></em>
Now, we know that, numerators and denominators should be proportional to be two fractions in proportion.

So numerators and denominators are in proportion, then given two fractions are proportion.
<em><u>Reason 2:</u></em>
Now, values of two fractions must be equal:

So, values of two fractions are equal, then they are in proportion.
Hence, the given two fractions are in proportion.
3x/8+1=9/8
3x/8+1(8/8)=9/8
3x/8+8/8=9/8
3x+8=9
3x=1
x=1/3
Answer:
y= -3
Step-by-step explanation:
I'll assume it is a linear line (straight line).
Sense the y-value doesn't change and stays -3, the equation for the line would be y= -3
And just so you know, the slope of the line would be 0.
