Any Math Wiz here? Help please..?

Question

Hello, can you help me? I'm not good in math so please help me. here's the question..

Q: A nectarine costs 3p more than a peach. Kamal buys 4 nectarines and 5 peaches. The total costs is £1.47.

Let x pence be the cost of a peach.

(a) Write down in terms of x:

i) The cost of all peaches..............................
ii) The cost of one nectarine..........................
iii) The cost of all the nectarines...................

(b)

i) Write down a equation for the total cost of the fruit.
ii) Solve the equation to find x.
iii) What is the cost of a nectarine?


-I'm from UK so I'm using £. 3p is 3pence. pence is same as cents. Please help me. Thank you.

To all answerers, if you don't want to answer it just leave it alone. Please don't say anything that's gonna hurt the feelings of the people who asks. If we know the answer or if we know how to answer this, we'll not ask such questions.

Answer 1

start out by writing the equations you know:
peach = x
nectarine = 3p + peach = 3p + x

So if Kamal buys 4 nectarines and 5 peaches:
4 nectarines + 5 peaches = 4(3p +x) +5x
We know this equals to 1.47

So multiply it out...
12p +4x +5x = 1.47
Solve for x...
12p + 9x = 1.47
9x = 1.47 - 12p
9x = 1.35
x = 1.35/9
x = 0.15

Therefore, a peach costs 15p.
We go back to the original equation for nectarine (3p + x)
Plug in x.
Therefore...3p + 15p = 18p

With this you should be able to answer all the other parts.
Good luck!

Answer 2

You need to understand how to get to the answer, here are the steps:

Let cost of each nectarine = X, then cost of each peach = X-3
Therefore

4X + 5 (X-3) = 147 pence
>> 4X + 5X - 15 = 147

Now you should be able to solve for X and find out the answers to every listed question

Answer 3

a) Write down in terms of x:

(i) The cost of all peaches.........5x
ii) The cost of one nectarine......x + 0.03
iii) The cost of all the nectarines.......4x + 0.12

(b)

i) Write down a equation for the total cost of the fruit.......9x + 0.12
ii) Solve the equation to find x...........x=15p (£0.15)
iii) What is the cost of a nectarine?........18p (£0.18)

In all of the answers is it is 0.00 the .00 is the equalivent to pence
hope i've helped

Answer 4

discover out what share quarters in a pound, or in 5 kilos and do the mathematics. case in point enable's say that there is $2 extremely worth of quarters in a pound (in basic terms guessing) multiply that via 35 and you get $70

Answer 5

a(i) 5x
a(ii) x+3
a(iii) 4(x + 3)
b(i) 5x+ 4(X + 3) = 147p.
b(ii) x = 15p
b(iii) Nectarine = 18p,

Answer 6

i) 5x (obviously)
ii) x+3
iii) 4x+12 or 4(x+3)

i) 5x+(4x+12)=147
3x+4=49
ii) 3x=45
x=15p
iii) 15+3=18p

Answer 7

I'm not that nice!
The answers for A are:
75p
18p
72p
and x is equal to 15 - so with that you should be able to work out the rest
