Answer:

a = 0

Step-by-step explanation:

On the right side of the = multiply -4 through

- 6a - 4 =  - 4 - 28a

add 28a and add 4 to both sides

28a - 6a = 4 - 4

22a = 0

divide both sides by 22

a = 0

A 6-kilogram bag of rice costs $3.80. What is the unit price, rounded to the nearest cent?
iragen [17]

Answer:

The unit price is <u>63 cent</u> per kilogram bag of rice.

Step-by-step explanation:

Given:

A 6-kilogram bag of rice costs $3.80.

Now, to find the unit price.

So, to get the unit price we use unitary method:

If cost of 6 kilogram bag of rice = $3.80.

Then cost of 1 kilogram bag of rice = \frac{3.80}{6}  = \$0.633.

Thus, the unit price is $0.633 per kilogram bag of rice.

Now, according to question we convert the unit price into cent by using conversion factor:

$1 = 100 cent

$0.633 = 0.633\times 100=63.3\ cent.

<em>So, rounded to nearest cent  = 63 cent.</em>

Therefore, the unit price is 63 cent per kilogram bag of rice.

I need help with question 3
agasfer [191]

Answer:

see explanation

Step-by-step explanation:

To find the y-intercept let x = 0, in the equation

6x - 3y = 15 → (1)

x = 0 : - 3y = 15 ⇒ y = - 5 ⇒ (0, - 5) ← y- intercept

x + 3y = - 8 → (2)

x = 0 : 3y = - 8 ⇒ y = -\frac{8}{3} ⇒ (0, - \frac{8}{3}) ← y- intercept
