Stolb23 [73]
\left \{ {{a+b=87} \atop {a-3b=7}} \right.



a-3b=7
a=7+3b

a+b=87
(7+3b)+b=87
7+4b=87
4b=87-7
4b=80
b=20

a=7+3b
a=7+3*20
a=7+60

Find a common difference of the arithmetic sequence -2, -1 4/5, -1 3/5, -1 2/5,
elixir [45]

Answer:

The common difference is \frac{1}{5} or 0.2

Step-by-step explanation:

Given:

Arithmetic Sequence -2, -1 4/5, -1 3/5, -1 2/5,

First term      = a₁ = -2

Second term = a₂ = \frac{-9}{5}

Third term     = a₃ = \frac{-8}{5}

Fourth term = a₄ = \frac{-7}{5}

To Find:

Common Difference = d = ?

Solution:

Formula for Common Difference d ,\textrm{common difference}= \textrm{Second Term} -\textrm{First Term}=\textrm{Third Term}-\textrm{Second Term}

\textrm{common difference} = a_{2}- a_{1}= a_{3}- a_{2}=a_{4}- a_{3}

∴ d = \frac{-9}{5}-(-2)\\d=\frac{-9}{5}+2\\d=\frac{1}{5}\\ \therefore d =0.2\\

The common difference is \frac{1}{5} or 0.2

On a trip, you had to change your money from dollars to British pounds. You got 560 pounds for 800 dollars. How many pounds will
leva [86]
<h2>Answer</h2>

210 pounds

<h2>Explanation </h2>

First, we are going to find the exchange rate from dollars to pounds.

We know form our problem that 800 dollars are 560 pounds. so:

\frac{560pounds}{800dollars} =0.7 pounds per dollar.

Next, we are going to multiply our exchange rate by the number of dollars we want to change, 300:

300dollars*\frac{0.7pounds}{dollar} =210pounds

We will get 210 pounds for 300 dollars

a store light flashes every 60 minutes while another light flashes open every 24 minutesif both stores begin flashing at 10 am w
anastassius [24]

Answer:

Both lights flash at 1:00

Step-by-step explanation:

they flash together every 2*7=14 minutes

in 60 minutes there are 4*14=56 minutes

they flash together at 1:56

more minutes brings you to 2:00

they flash together at 2:10 (4+10=14)

that leaves 50 minutes left in the hour

they flash three times which uses up 42 minutes

this brings you to 2:52 (10+42=52)

8 more minutes brings you to 3:00

in 6 more minutes (8+6=14) it will be 3:06 and they will flash together
