Answer:
x = - 4
Step-by-step explanation:
First do distributive property
5x-15=10x+5
then add 15
5x=10x+20
-10x
-5x=20
divide 5
x=-4
5
40/8 is 5. You can check this by multiplying 8 and 5 and seeing if it equals 40. Also, if you look at 40/8 as a fraction you can simplify it. 40/8=20/4=10/2=5/1=5
For this case we have by definition:
1 Pint is equal to 0.5 quart
We must indicate how many quarts there are in 120 pints.
Making a rule of three we have:
1 pint --------------------> 0.5 quart
120 pints -------------> x
Where the variable "x" represents the number of quarts equivalent to 120 pints.
Thus, 120 pints are equivalent to 60 quarts
Answer:
Option C
180
<span>3*60 </span>
<span>3*3*20 </span>
<span>3*3*4*5 </span>
<span>3*3*2*5 </span>
<span>which simplifies to 2^2*3^2*5

I hope I helped!
5x+12z Because you take, 3z+9z and that is equivalent to 12z. and then you put the 5x back into the equation so it is 5x+12z
