Answer:
x = - 6
Step-by-step explanation:
Given
x² = 24 ( multiply both sides by 3 )
2x² = 72 ( divide both sides by 2 )
x² = 36 ( take the square root of both sides )
x = ± ← note plus or minus
x = ± 6
solutions are x = - 6, x = + 6
The smallest solution is x = - 6
Answer:
x = 9
y = 3
Step-by-step explanation:
2x + 2y = 24 is the same as x + y = 12
using substitution, x = 12-y
12 - y = 3y
12 = 4y
y = 3
x = 3(3)
x = 9
Answer:

7.7 because it is more specific into the whole number but not just that and the decimal
Answer:
12 different sums
Step-by-step explanation:
there's three darts and three numbers.
if you use the factorial 3! for both the number of darts and the score numbers and add the two together, you would get twelve :
( 3! = 3*2*1 = 6 ) * 2
6 + 6 = 12
or you could just write out all the combinations like this :
2+2+2
2+2+5
2+5+5
2+5+8
2+8+8
5+5+2
5+5+5
5+5+8
5+8+8
8+8+2
8+8+5
8+8+8
