X - y = 0.85
x + y = 1
----------------add
2x = 1.85
x = 1.85/2
x = 0.925
x + y = 1
0.925 + y = 1
y = 1 - 0.925
y = 0.075
so ur 2 numbers are : 0.925 and 0.075
Answer:
- 3x² + x + 5
Step-by-step explanation:
Given
(4x + 5) + (- 3x² - 3x) ← remove parenthesis
= 4x + 5 - 3x² - 3x ← collect like terms
= - 3x² + (4x - 3x) + 5
= - 3x² + x + 5
Yes
2828.
One says 28 is less than x and the other say x is more than 28.
It's just written in a different order is all.
Answer:
£312
Step-by-step explanation:
Amount spent on 60 jumpers = £120
80% of the jumpers :
0.8 * 60 = 48 jumpers
Sales price for 80% = £8 each
Total = £8 * 48 = £384
The remain at an half price offer :
Half price = £8 / 2 = £4
£4 * (60 - 48)
£4 * 12 = £48
Total sales revenue = £(48 + 384) = £432
Total profit made :
Total sales revenue - purchase price
£432 - £120
= £312
