Answer: £535

Step-by-step explanation:

Herr is the complete question:

Tim and three friends go on holiday together for a week.

The 4 friends will share the costs of the holiday equally,

Here are the costs of the holiday.

£1280 for 4 return plane tickets

£640 for the villa

£220 for hire of a car for the week

Work out how much Tim has to pay for his share of the costs.

Firstly, we have to calculate the total cost of the holiday. This will be:

= £1280 + £640 + £220

= £2140

We are also told that they will share the costs equally. Since there are 4 people, Tim will have to pay:

= £2140 ÷ 4

= £535

Tim will pay £535

Separate the x- and y-values with a comma.<br> X=-3+y<br> 26x - 5y = 6
labwork [276]

Answer:

The solution of the given system is (x,y) = (1,4)

Step-by-step explanation:

Here, the given system of equation is:

x  = -3 + y

26 x - 5 y =  6

Now, substitute x  = -3 + y in the second equation , we get

26 x - 5 y =  6  ⇒   26 (-3 + y) - 5 y =  6

or, 26(-3)  + 26(y)  - 5y = 6

⇒ - 78 + 26 y - 5y = 6

⇒   21 y =  84

⇒  y = 84 / 21 = 4   or ,   y =  4

So x  = -3 + y  =  -3 + 4 = 1

Hence, the solution of the given system is (x,y) = (1,4)

A bag of corn tortilla chips costs 2.89 after a 15% discount. What is the original price?
Montano1993 [528]

Answer:

3.4

Step-by-step explanation:

Let the original price of the bag be = P, the selling price =2.89 after a 15% discount,

Then, Selling price= Original price- Discount on original price

2.89=P-P(0.15)

2.89=P(1-0.15)

2.89=0.85P

P=\frac{2.89}{0.85}

P=3.4

Thus, the original price was 3.4.

If the acceleration of an object is given by dv/dt = −2v, Find the position function s(t) if v(0) = 7 and s(0) = 0.
kirill [66]

Answer:

Step-by-step explanation:

Given that acceleration of an object is

\frac{dv}{dt} =-2v\\\frac{dv}{v} =-2dt\\ln v = -2t+C\\

is the solution to the differential equation

Since v(0) =7

we get ln 7 = C

Hence lnv = -2t+ln 7\\v=7e^{-2t}

since velocity is rate of change of distance s we have

v=\frac{ds}{dt} =7e^{-2t}\\s= [tex]s(t) =\frac{-7}{2} (e^{-2t})+C)[

substitute t=0 and s=0

C=7/2

So solution for distance is

s(t) =\frac{-7}{2} (e^{-2t}-1)

39+5h+4g-2h i have been trying 2 work this out 4 ages so plz help
SIZIF [17.4K]
Unless you're given the value of the variables, you can't really solve for anything. The only thing you can do is simplify. 

<span>39+5h+4g-2h
The only like terms are 5h and -2h.

39 + 3h + 4g
This would be the simplified version.</span>

Find the x is qs bisects pqr and pqr=82
slavikrds [6]

if ∡PQR = 82°, and the ray QS bisects it, it cuts ∡PQR into two equal halves, ∡PQS and ∡RQS, each of which is then 82/2, or 41°.


\bf \stackrel{\measuredangle PQS}{10x+1}=41\implies 10x=40\implies x=\cfrac{40}{10}\implies x=4
