Answer:
55p
Step-by-step explanation:
iced cake = 10p more than a plain cake
iced cake = 10p + plain cake
iced cake and a plain cake together = £1
iced cake + plain cake = £1
if iced cake = 10p + plain cake, we can plug this into our second formula to get
(10p + plain cake) + plain cake = £1
10p + 2 * plain cake = £1 = 100p
subtract 10p from both sides to isolate the variable and its coefficient
2 * plain cake = 90p
divide both sides by 2 to isolate the variable
plain cake = 45p
iced cake = 10p + plain cake = 55p
Answer:
Nope i don't understand the question what do you need help with?
Step-by-step explanation:
If you would like to solve 32 + 5yi = 16x - 40i for y, you can do this using the following steps:
<span>32 + 5yi = 16x - 40i
</span>5yi = 16x - 40i - 32 /5
yi = 16x/5 - 8i - 32/5 /i
y = 16x/5i - 8 - 32/5i
The correct result would be <span>y = 16x/5i - 8 - 32/5i.</span>
You work out the price of each share:
$2500 ÷ 125 = $20 each
10% of that is $2, which added on means the share is worth $22
Hope it helps:-)
