Answer:
12 feet
Step-by-step explanation:
4.5 pieces of rope = 9/2 pieces in fractions
Also, 2 2/3 can be rewritten as 8/3 in fractions
So, 9/2 *8/3 = 72/6 = 12 feet
Allyson has 12 feet of rope in all.
V = a * b * c
a,b,c- lengths of sides
in here a=b=c=5cm
V=5*5*5 = 125 cm^3
or
V=a^3 = 5^3 =125 cm^3

Step-by-step explanation:
Answer:
D
Step-by-step explanation:
Given the 2 equations
4x - 5y = 18 → (1)
3x - 2y = 10 → (2)
Multiplying (1) by 3 and (2) by - 4, then adding will eliminate the x- term
12x - 15y = 54 → (3)
- 12x + 8y = - 40 → (4)
Add (3) and (4) term by term to eliminate x, that is
- 7y = 14 ( divide both sides by - 7 )
y = - 2
Substitute y = - 2 into either of the 2 equations and solve for x
Substituting into (1)
4x - 5(- 2) = 18
4x + 10 = 18 ( subtract 10 from both sides )
4x = 8 ( divide both sides by 4 )
x = 2
solution is (2, - 2 ) → D
