Answer:
Step-by-step explanation:
8.2 comes between 8 and 9
8.2 = 
.
As you know, the interval between 8 and 9 is divided into 10 equal parts and each part is 1/10 or 0.1.
Answer:
Step-by-step explanation:
2 * L + 2 * W = 68
2*L = 2* 9x = 9x + 9x
2*W = 2*8x = 8x + 8x
Since the perimeter is 68
9x + 9x + 8x + 8x = 68
X = number of dimes
y = number of quarters
---
10x + 25y = 2565
y = x + 20
---
put the system of linear equations into standard form
---
10x + 25y = 2565
x - y = -20
---

x = 59
y = 79
Answer:C
Step-by-step explanation:
the line above AB signifies that its a line segment
there are points for A and B
Marina is taller because since Juan is 4 feet, he is 48 inches tall and Marina is 52 inches tall so Marina is taller than Juan.
