The image isn’t working, just letting you know
312 gallons of white paint, $17.50 each gallon
134 gallons of blue paint, $19 for each gallon
312 x 17.50 = $5,460
134 x 19 = $2,546
5460 + 2546 = $8,006
Answer:
60m^2
Step-by-step explanation:
Ok so if you subtract the 18 by 12 then divide by two you get the missing lengths of each of te triangles. If you then use the area of a trapezoid formula (think about it like pulling one triangle off one side and putting it next to the other to make a rectangle) you just do L x W and get 60.
Answer:
(-1,-3)
Step-by-step explanation:
The given system of equations is;
and
Let us equate the two equations to get;
Group similar terms;
Simplify;
Divide both sides by 9.
Put x=-1, into any of the equations, say (2);
The solution is;
(-1,-3)
