Expression: 6x - 3y

  • x = 5
  • y = -1

Solution: If we substitute the values of x and y into the problem, we get 6(5) - 3(-1); 6 times 5 is <u>30</u>, and 3 times -1 is <u>-3</u>... 30 - (-3) becomes 30 + 3 = 33!!

Draw an area model that demonstrates that the quotient of 2080 and 40 is 52.
Scrat [10]

Area model is used to illustrate multiplication and division operations.

See attachment for the area model

The equation can be represented as:

\frac{2080}{40} = 52

Express 2080 as 1200 + 800 + 80

\frac{1200 + 800 + 80}{40}=52

Express as

\frac{1200 + 800 + 80}{40}=\frac{1200}{40} + \frac{800}{40} + \frac{80}{40}

Divide

\frac{1200 + 800 + 80}{40}= 30 + 20 + 2

See attachment for the area model

How do I do this. Due tomorrow
kolbaska11 [484]
I prefer D.

It's clear that Kevin took (1/4)x.
Keith took (1/4)x -> kevin's amount
                 * 2      -> twice.
                 -1       -> 1 less.

So Kevin + Keith = (1/4)x + (1/4)x * 2 - 1 = (3/4)x - 1.

Please explain! <br><br> 1/2x+1/8y=3<br><br> Solve in Slope Intercept form.
charle [14.2K]

Answer:

y = 4x + 24

Step-by-step explanation:

The slope is the number in front of the x-value.

Slope intercept form is in the form of

y = mx + b  (or as how I learned it)

m is the slope, and b is the y-intercept (the number that is left on the side.)

You can rearrange this by moving the x to the right side by subtracting it from both sides.

You now have 1/8y = 3 - 1/2x

which can be rearranged to

1/8y = -1/2x + 3.

You need to change the y to 1 whole instead of 1/8, so you multiply it by 8 since 8 divided by 8 is 1.

y = -4x + 24
