Answer:
1) x < 1, x > 9
2) 2 < x ≤ 6, -4 ≤ x < 0
Step-by-step explanation:
1) lx - 5l > 4
x - 5 = 4
x = 9
-(x - 5) = 4
x = -4 + 5 = 1
x < 1, x > 9
3) 1 < lx-1l ≤ 5
1 < x-1 ≤ 5
2 < x ≤ 6
1 < -(x-1) ≤ 5
-5 ≤ x-1 < -1
-4 ≤ x < 0

John would need 270 tiles and he does not have enough money to buy the tiles he needs. He only has $400 and he would need $405.
Answer:
B
Step-by-step explanation:
Evaluate the numerator/ denominator using order of operations
numerator = 16 + 2(4 × 2)
using the order parenthesis, multiplication followed by addition
= 16 + 2(8) ← evaluating parenthesis
= 16 + 2 × 8
= 16 + 16 ← performing multiplication
= 32 ← addition
denominator = 8 + 2³
using the order exponents then addition
= 8 + 8 ← evaluating exponent
= 16 ← addition
Hence
=
= 2 → B
