Step-by-step explanation:

slope 2.5 y intercept 3

If y varies directly with x, and y = 2 when x = −4, what is the value of y when x = 20 ?

Answers

Answer:

y=kx

2=k.-4

k=-1/2

then

y=-1/2×20

y=-10

Answer:

y = - 10

Step-by-step explanation:

Given that y varies directly with x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 2 when x = - 4, that is

2 = - 4k ( divide both sides by - 4 )

[tex]\frac{2}{-4}[/tex] = k, that is

k = - [tex]\frac{1}{2}[/tex]

y = - [tex]\frac{1}{2}[/tex] x ← equation of variation

When x = 20, then

y = - [tex]\frac{1}{2}[/tex] × 20 = - 10

If a sweatshirt cost $45, and sales tax is 7%, how much tax did you pay?

Good Luck!!! :)

Answer:

Step 1: take the total price and divide it by one plus the tax rate.

Step 2: multiply the result from step one by the tax rate to get the dollars of tax.

Step 3: subtract the dollars of tax from step 2 from the total price.

Pre-Tax Price = TP – [(TP / (1 + r) x r]

TP = Total Price

A window-washing crew can finish 15 windows in 18 minutes.

If this crew was assigned to wash all of the 24,348 windows on the outside of the Burj Khalifa at this rate, how long will the crew be washing at this rate?

Answers

Answer:

34321.2 min

Step-by-step explanation:

The Burj Khalifa has in total 28601 windows. On the other hand, we are told the window-washing crew can wash 15 windows in 18 minutes. So, we can use the Rule of three to solve this problem:

If:

15 windows ---- 18 min

28601 windows ---- ?

Then:

? = (28601windows)(18min)/15windows

? = 34321.2min

1.4 you subtract normally it as if you were doing whole numbers

Answer:

1.4 or 30.8

Step-by-step explanation:

1.4 is for regular math because it's basically 16.1 - 14.7

30.8 is for KCO or Keep Change Opposite (Beginners math)

Basically it would turn the equation into 16.1 + 14.7

You can use either but if you aren't sure ask your teacher about the strategy.

Hope this helps and if not tell me your strategy.
