Answer:
m= 9/5 n - 3
Step-by-step explanation:
Let's solve for m.
−5m+9n=15
Step 1: Add -9n to both sides.
−5m+9n+−9n=15+−9n
−5m=−9n+15
Step 2: Divide both sides by -5.
-5m/-5 = -9n+15/-5
m= 9/5 n - 3
Answer:
y= -17x-120.
Step-by-step explanation:
1) according to the condition the lines are parallel. It means the slope of the required line is -17;
2) if to substitute the (-7;-1) into the equation y= -17x+i, then i= -120;
3) the required equation of the line is y= -17x-120.

13.56=1kg
answer is $13.56 for 1kg
First, subtract 5 from both sides of the equal sign.
3/7x + 5 - 5 = 8 - 5
+5 and -5 cancel out
3/7x = 8-5=3
3/7x = 3
Now, divide both sides of the equation by (3/7).
x = 3/(3/7)
When you have to divide by a fraction, you can change it to multiplying by the reciprocal. The result will be the same.
So,, change 3/3/7 to 3 x (7/3)
Then solve
3 x 7 / 3 = 21/3 = 7
So,, x = 7.
