Answer:
This equation has ONE unique solution, which is x = 1.
Step-by-step explanation:
Let's actually solve this equation, 0.9x+5.1x-7=2(2.5x-3).
Mult. all four terms by 10 to eliminate the fractions:
9x+51x-70=2(25x-30)
Perform the indicated multiplication:
9x+51x-70= 50x - 60
Combine like terms: 60x - 70 = 50x - 60 => 10x = 10, and x = 1
This equation has ONE unique solution, which is x = 1.
Answer:
1560
Step-by-step explanation:
First (2 1/2)/(1/4) = (5/2)(4) = 20/2 = 10
Next, 3/(1/4) = 3(4) = 12
Lastly, (3 1/4)/(1/4) = (13/4) x 4 = 52/4 = 13
This means we need 10 rows of 12, 13 high. 10(12)(13) = 1560 cubes.
Another way is to multiply 2 1/2 x 3 x 3 1/4 = 5/2 x 3 x 13/4 = 195/8
A 1/4 inch cube is 1/4 x 1/4 x 1/4 for a volume of 1/64
(195/8)/(1/64) = (195/8)(64) = 1560 cubes.
Answer:
