3(4h+3d=18.25)-2(6h+4d=26.50)
12h+9d-12h-8d=54.75-53
d=1.75, use either original equation to solve for h...
4h+3(1.75)=18.25
4h+5.25=18.25
4h=13
h=3.25
So the cost of one hamburger and one drink is:
3.25+1.75=$5.00
Answer: choice B) 59 square inches

Work Shown:
A1 = Area of rectangle = length*width = 7*4 = 28 square inches
A2 = Area of triangle on top = 0.5*base*height = 0.5*7*6 = 21 square inches
A3 = Area of triangle on right side = 0.5*base*height = 0.5*4*5 = 10 square inches
Total Area = A1 + A2 + A3
Total Area = 28 + 21 + 10
Total Area = 59 square inches
Answer:
11 and 23
Step-by-step explanation:
Ok So, 5+3=8x2=16-6=10 :)
The like terms can be grouped by their variables and exponents. Let's do that.
Now, just add each group of like terms together by adding their coefficients.
Now, add all the terms together.
