The converse of the statement would be
"If x ≤ 7, then x² ≤ 49"
but this is false. Take x = -8; while it's true that -8 ≤ 7, the second inequality is not, since (-8)² = 64 is not smaller than 49.
Answer:
Step-by-step explanation:
If cost price (CP) is greater than selling price (SP) , then the item is sold for loss.
Loss = CP - SP
Loss% = 
If SP is greater than Cp, then the item is sold for a profit.
Profit =SP -CP
Gain % = 
a) CP = $50 ; SP = $30 ; CP > SP, loss
Loss = 50 - 30 = $ 20
Loss % = 
= 40% loss
b) CP = £ 5000 ; SP = £6250 ; SP > CP , Profit
Profit = 6250 - 5000 = £ 1250
Profit % = 
25% Profit
Together they equal 90 degrees.
Equation:
(0.1x - 22) + (0.3x - 54) = 90
Open parenthesis and simplify:
0.4x -76 = 90
0.4x = 166
DIvide:
Your final answer is x= 415
