Answer:
-4 ≤ x <7
x is greater than or equal to -4, and x is less than 7
Step-by-step explanation:
Take each side and solve
-12 ≤ 2x -4
subtract 4 on both sides
-8 ≤ 2x
divide by 2 on both sides
-4 ≤ x
2x -4 < 10
add 4 on both sides
2x < 14
divide by two on both sides
x < 7
Final answer:
-4 ≤ x <7
Answer:
2 2/3 lbs
Step-by-step explanation:
Convert Alya's mixed number to an improper fraction
3*1+1 = 4/3
multiply 4/3 times 2/1
4*2 = 8
3*1 = 3
8/3 - convert back to mixed number
8/3 = 2 2/3
10! = 10 * 9 * 8* 7 *6 *5 *4 *3 *2 *1 = 3628800
5! = 5*4*3*2*1 = 120
2! = 2*1 = 2
5! x 2! = 120 * 2 = 240
10! / 5!2! = 362880 / 240 = 15,120
