Okay. So you can go 440 miles on 10 miles of gas. That’s 44 miles for 1 gallon of gas. For 60 miles of gas, you have to do 440 * 6. When you do that, your product should be 2,640. You can drive 2,640 miles on 69 gallons of gas and 44 miles per gallon of gas.
We find the answer by using the density formula: d =m/v
We know the density: 0.1785
We know the volume: 3,249
We DO NOT know the mass, so that is what we're trying to finding
0.1785 = m/3,249
Solve:
3,249 * 0.1785 = m/3,249 * 3,249
579.9465 which can be rounded to 579.9
The answer is D.
Answer:
Break down the problem into these 2 equations.
a+6=3a+2
a+6=3a+2
a+6=2a
a+6=2a
Solve the 1st equation: a+6=3a+2a+6=3a+2.
a=2
a=2
Solve the 2nd equation: a+6=2aa+6=2a.
a=6
a=6
Collect all solutions.
a=2,6
a=2,6

Answer:
soln,
write the question
=9x^2+1-6x-2×9x^2+25+9x^2+25
=9x^2+1-6x-18x^2+25+9x^2+25
=9x^2-18x^2+9x^2+1+25+25-6x
=51-6x
if(3x+1)^2 mean that (3x+1)has power of 2 and u don't have to use the formula this is the answer
Step-by-step explanation:
it's just BODMAS method
