The math club sells candy bars and drinks during football games.

Vinvika [58]

Answer:

The price of candy bar is 75 cents

Step-by-step explanation:

Let c be the price of candy bar and d be the price of drinks

Then according to given statements

$60c+110d = 265\ \ \ \ Eqn\ 1\\120c+90d = 270\ \ \ \ Eqn\ 2$

Multiplying equation 1 by 2

$120c+220d = 530\ \ \ \ Eqn\ 3$

Subtracting equation 2 from equation 3

$120c+220d - (120c+90d) = 530 - 270\\120c+220d-120-90d = 260\\130d=260$

Dividing both sides by 130

$\frac{130d}{130} = \frac{260}{130}\\d = 2$

Putting d=2 in equation 1

$60c+110(2) = 265\\60c + 220 = 265\\60c+220-220 = 265-220\\60c=45\\c = \frac{45}{60}\\c = 0.75$

Price of candy bar is $0.75 or 75 cents

Hence,

The price of candy bar is 75 cents

Consider the sequence {3,6,9,12,15,…}. Find n if an = 735. Show all steps including the formulas used to calculate your answer.

vekshin1

Answer:

n = 245

Step-by-step explanation:

The given sequence is 3,6,9,12,15,…

nth term of the AP is 735

We know that, the nth term of an AP is given by :

$a_n=a+(n-1)d$

d is common difference, d = 6-3 = 3

Put all the values to find n.

$735=3+(n-1)3\\\\732=(n-1)3\\\\\dfrac{732}{3}=n-1\\\\n=244+1\\\\n=245$

So, there are 245 terms in the sequence.

krok68 [10]

Answer:

x > -4

Step-by-step explanation:

The given inequality is :

6x - 5 > -29

Adding 5 to both sides of the inequality

6x - 5 +5 > -29 + 5

6x > -24

Dividing both sides by 6

x > -4

So, the solution of the given inequality is x > -4.
