Answer:
They did not flip the inequality
Step-by-step explanation:
-x/4 < (x+2)/3
Multiply each side by 3
-3x<4x+8
Subtract 4x from each side
-3x-4x <4x-4x +8
-3x-4x<8
Combine like terms
-7x<8
Divide by -7. Remember to flip the inequality
-7x/-7 > 8/-7
x > -8/7
First, you calculate the total amount of parts : 7 + 3 = 10
Next, divide the number by the total amount of parts : £500 ÷ 10 = £50
After that, you multiply the answer by the amount of parts needed on both sides of the ratio : £50 × 3 = £150 and £50 × 7 = £350
Finally put these answers back into the ratio : £150:£350
To check, make sure both sides of the ratio add up to the original number : £150 + £350 = £500

Step-by-step explanation:
Since, y varies inversely as x.
