Answer:
amount of money earned; hours worked; $0 to $480; 0 to 40
Step-by-step explanation:
Let l = length
Let w = width
l + w = 24
143 = lw
We have two equations and two unknowns.
Can you proceed?
Answer:
(a) C = 25r (b) 8 rooms (c) 7 rooms
Step-by-step explanation:
MARK ME BRAINLIEST PLEASE!!!!!!!!
(a) C=25r
(b) C = 25r
200 = 25r,
200/25 = 25r/25
200/25 = 8
8 = r, therefore 8 rooms can be cleaned for $200
(c) 200-25 = 25r
200-25=175, so 175 = 25r, then divide both sides by 25, and you get
7 = r , so therefore 7 rooms can be cleaned for $200
The equivalent equation of the algebraic Equation (4x - 7)² + 16 = 40x - 70 is; p² + 16 - 10p = 0
<h3>How to simplify Algebraic Equations?</h3>
We want to simplify the algebraic Equation;
(4x - 7)² + 16 = 40x - 70
Factorize right hand side to get;
(4x - 7)² + 16 = 10(4x - 7)
If p = 4x - 7, then we have;
p² + 16 = 10p
Using subtraction property of equality gives;
p² + 16 - 10p = 10p - 10p
p² + 16 - 10p = 0
