The last one is the right answer b/c 7 plus 0.30 for each topping, -> t
Answer: it’s the third graph
1. {2x−3y=9
{3x+5y=4
2. {(2x−3y=9)×5
{(3x+5y=4)x3
3. {10x-15y=45
{9x+15y=12
4. (10x-15y=45) + (9x+15y=12)= (19x=57)
5. (19x=57)÷19
6. x=3
7. 2(3)-3y=9
8. 6-3y=9
9. -3y=9-6
10. (-3y=3)÷(-3)
11. y=-1
Answer: x=3 and y=-1
Answer:760ft2
Step-by-step explanation:
Area of first triangle = 1/2bh = 1/2*8*15=60ft2
Area of second triangle = 60ft2
Area of bottom rectangle =20*15=300ft2
Area of top rectangle = 17*20=340 ft2
Total surface area =60+60+300+340
=760ft2
