Answer:
Friday: 300 dollars
Step-by-step explanation:
Let Omar's pay on Friday = x
Friday: x
Saturday: 1/4 x was spent.
Sunday: 2/3 *(x - (1/4)x ) = 2/3 * (3/4x) = (2*3/(3*4)x = (6/12)x = 1/2x
Dinner: 15 dollars
Remainder = 20% x = 20/100 x = 0.2x
x - (1/4x + 1/2(x) + 15) = 0.2x Combine like terms on the left
x - (3/4x + 15) = 0.2x Remove the brackets
x - (3/4)x - 15 = 0.2x Combine like terms on the left
(1/4)x - 15 = 0.2x Change 1/4 to a decimal
0.25x - 15 = 0.2x Subtract 0.25x from both sides
0.25x - 0.25x - 15 = 0.2x - 0.25x Combine
- 15 = - 0.05x Divide by - 0.05
-15 /-0.05 = - 0.05 x/ 0.05
300 = x

Answer:
h greater-than-or-equal-to negative 432
Step-by-step explanation:
* multiply each side by -24 *
IMPORTANT NOTE: when multiplying an inequality by a negative number you must flip the sign. So if the inequality sign was once facing the constant ( 18 ) then it will flip and face the variable ( h )
Thus,
h ≥-432
Which can also be expressed as h is greater than or equal to negative 432
Extra notes: You only have to flip the inequality sign if it's being multiplied by a negative number. Meaning if its multiplied by a positive number then the inequality sign does not flip.
The answer is hundred and twenty-two decimal eight
