Answer:
There is no graph
Step-by-step explanation:
One has to solve this using either substitution or elimination then...
x + y = 5
–2x + y = –4
x + y = 5
2x –y = 4
3x = 9
x = 3
y = 2
Solution (3 , 2)
to get to 45mins you have to multiply
15 min by 3 to get 45mins. If you do it on the bottom you do it on the top. so you then multiply 2miles by 3 to get 6miles. So he travels 6 miles in 45 mins.
Answer:
A quarter of a pound, or 0.25
Step-by-step explanation:
Answer:
Area of A: 9pi
5.4 Times greater
Step-by-step explanation:
Circle A Radius: 3
B Radius: 3+A (6 total)
C Radius: 3+B (9 total)
D Radius: C-2 (7 total)
Area of each Circle using formul pi*radius²
A: 9pi
B: 36pi
C: 81pi
D: 49pi
49/9 = 5.4 Circle D is 5.4 times greater then A
