Answer:
100 sweets
Step-by-step explanation:
Let initial number of sweet = x
Monday :
2/5 of x = 2x/5
Number left = x - 2x/5 = 3x/5
Tuesday :
2/5 of remaining = 2/5 * 3x/5 = 6x/25
Number left = 3x/5 - 6/25 = 9x/25
Wednesday :
2/3 of remaining = 2/3 * 9x/25 = 18x/75
Number left = 9x/25 - 18x/75 = 9x / 75
9x/75 corresponds to 12
9x/75 = 12
Cross multiply :
9x = 12 * 75
9x = 900
x = 900 / 9
x = 100 sweets
Answer: £137
Step-by-step explanation:
Since Sean sold both items for £1,500 getting £1,300 just for the laptop, the slave price of the printer will be:
= £1500 - £1300
= £200
Since we are informed that Sean made a 46% profit on the cost of the printer, the cost of the printer goes thus:
= £200 /(1 + Profit percent)
= £200 / (1 + 46%)
= £200 / 1.46
= £136.99
= £137 approximately

Answer:
y = -2x + 5
Step-by-step explanation:
In order to be perpendicular to a given line, the other line must have an opposite reciprocal slope.
Answer:
<u>A. (7x)³ + 8 ⇔ 8 added to the product of 7 and x cubed</u>
<u>B. 7x³ + 8 ⇔ 8 added to cube of 7x</u>
<u>C. 7 (x + 8)³ ⇔ 7 times the cube of the sum of x and 8</u>
<u>D. (7x + 8)³ ⇔ the cube of the sum of 7x and 8</u>
Step-by-step explanation:
1. Let's drag the tiles to the correct boxes to complete the pairs.
A. (7x)³ + 8 ⇔ 8 added to the product of 7 and x cubed
The second tile was already given and solved, however we're copying it.
B. 7x³ + 8 ⇔ 8 added to cube of 7x
C. 7 (x + 8)³ ⇔ 7 times the cube of the sum of x and 8
We use the expression 7 times because number 7 is multiplying the sum inside the parenthesis.
D. (7x + 8)³ ⇔ the cube of the sum of 7x and 8
