Answer:

x=10

Step-by-step explanation:

1/5(x)-2/3=4/3

Add 2/3 to each side

1/5(x)-2/3+ 2/3=4/3+2/3

1/5x = 6/3

1/5 x = 2

Multiply each side by 5

1/5x *5 = 2*5

x = 10

Answer:

x = 10

Step-by-step explanation:

\frac{1}{5}x-\frac{2}{3}= \frac{4}{3}\\\\

Add 2/3 to both sides

\frac{1}{5}x-\frac{2}{3}+\frac{2}{3}=\frac{4}{3}+\frac{2}{3}\\\\\\\frac{1}{5}x=\frac{6}{3}\\\\\\\frac{1}{5}x=2\\\\

Multiply both sides by 5

5*\frac{1}{5}x=2*5\\

x = 10

The explicit formula for an arithmetic sequence is an = 20 + (n − 1)(2). What is the 200th term?
Andrews [41]

Answer:

a_{200}=418

Step-by-step explanation:

The explicit formula for an arithmetic sequence is given by :

a_n=20+(n-1)2 ...(1)

We need to find the 200th term of the sequence.

Put n = 200 in equation (1)

a_{200}=20+(200-1)2\\\\=20+199\times 2\\\\=418

So, the 200th term of the sequence is 418.

Work out the percentage change to 2 decimal places when a price of £57.99 is decreased to £49.99.
IRISSAK [1]

Answer:

Percentage change in price = 13.80%

Step-by-step explanation:

Given that:

Original price = £57.99

Decreased price = £49.99

Difference = Original price - Decreased price

Difference = 57.99 - 49.99

Difference = £8.00

Percent change = \frac{Difference}{Original\ price}100

Percent change = \frac{8.00}{57.99}*100

Percent change in price = 13.80%

Hence,

Percentage change = 13.80%

What is the rate of change of y=-4/9x+5
WARRIOR [948]

Answer:

Rate of change of y is -  \frac{4}{9}

Step-by-step explanation:

y =  -  \frac{4}{9} x + 5 \\  \\ differentiating \: with \: respect \: to \: x \\  \\  \frac{dy}{dx}  =  -  \frac{4}{9} \frac{d}{dx} x +  \frac{d}{dx} 5 \\  \\  \frac{dy}{dx}  =  -  \frac{4}{9} .1 +  0 \\  \\  \huge \red{\frac{dy}{dx}  =  -  \frac{4}{9} } \\  \\ rate \: of \: change \: of \: y =-  \frac{4}{9}
