Given:

The equation is

$-3(2x-3)=33$

The incorrect solution steps are given.

To find:

The first error.

Solution:

We have,

$-3(2x-3)=33$

Using distributive property, we get

$-3(2x)-3(-3)=33$

$-6x+9=33$

The given step 1 is $-6x+6=33$ , which is not correct.

Therefore, there is first error in step 1 because the distribution property is not used properly.

Hence, the correct option is D.

In this problem, volume is computed:

volume = ∫(flow rate)·dt

.. = ∫[0, t] (3/10)*sin(2πt/7)·dt

= (3 / 10)*(7 /(2 π))*(-cos (2 π t/7)+1)

= (-21 / (20 π))*(cos (2 π t /7) - 1)

Volume is equal to 21 sin^2 (pit/7) / 10pi is the inhaled air in the lungs at time t

Harry went to the bakery with $50 to buy cupcakes and fruit tarts. One cupcake costs $3.50 and one fruit tart costs $3. Harry bo

mote1985 [20]

Answer:

$28+3x\leq 50$

Step-by-step explanation:

We are given the following in the question:

Cost of one cupcake = $3.50

Cost of one fruit tart = $3

Total money Harry have = $50

Harry bought 8 cupcakes and $x$ fruit tarts.

We have to write the inequality giving relation between the total number of cupcakes and fruit tarts Harry can buy the amount of money he has.

Total cost of purchase =

= Total cost of cupcakes + Total cost of fruit tarts

$=(8\times 3.50) + (x \times 3)\\=28 + 3x$

Now, this total cost of Harry's purchase should be less than than equal to $50.

$28+3x\leq 50$

is the required linear inequality.
