Answer: -15/8
Step-by-step explanation:
Using PEMDAS:
[18-(-8)^2] + 16 / 2^4
(18-64)+16 / 16
-46+16 / 16
-30/16
(Simplified) -15/8
Answer:
a) 3 gallons
b) 20 scoops
Step-by-step explanation:
Ratio values can be multiplied by a suitable constant to obtain an equivalent ratio.
You have ...
scoops : gallons = 4 : 1 = 12 : 3 = 20 : 5
a) 3 gallons of water should be used with 12 scoops of mix
b) 20 scoops of mix should be used with 5 gallons of water
Answer:
see explanation
Step-by-step explanation:
Inequalities of the type | x | ≤ a always have solutions of the form
- a ≤ x ≤ a
Given
| x - 1 | ≤ 1 then
- 1 ≤ x - 1 ≤ 1 ( add 1 to each of the 3 intervals )
0 ≤ x ≤ 2
Since we require an integer solution then x = 0, 1, 2
