First convert the first equation to combine like terms. Then set your equations up as an addition problem. You want at least one of your variables (y) to be of opposite values so the will cancel out to leave you with just one variable (x). Plug in 1/3 for the x into one of the equations to solve for y. Then write as an ordered pair.

First we need to figure out how much gas the car has in its tank so 3/4 of 12 is 9. Now we need to figure out an equation to use to solve this problem. 
Let x=distance

30/1.5=x

Multiply 30 and 1.5 by 6 because we have a 9 gallon tank.

180 miles for a 9 gallon tank. 

I think the best answer is D. because you can't really go more than you have in your tank. But you can go under and still have enough fuel to fill up.

NISA [10]

There are several expanded forms for a decimal number. Pick the one that matches your requirements.

64,375 = 60,000 +4,000 +300 +70 +5

64,375 = 6×10,000 +4×1,000 +3×100 +7×10 +5×1

64,375 = 6×10⁴ +4×10³ +3×10² +7×10¹ +5×10⁰

Which formulas can be used to find the surface area of a right prism where p is the perimeter of the base, h is the height of th
svp [43]
Let
ba--------> area of bases (<span>the two bases included</span>)
p---------> perimeter of the base
h--------> height of the prism  
la-------> lateral area

we know that

[surface area]=2*[area of one base]+[perimeter of the base]*height 
so
2*[area of one base]=ba
[surface area]=[ba]+[p]*h

and 
the formula of lateral area is
[la]=[perimeter of the base]*height
[la]=[p]*h
therefore
[surface area]=[ba]+[la]

the answer is
[surface area]=[ba]+[p]*h
[surface area]=[ba]+[la]
