Answer:

7\times 200+7\times 50+7\times 6

Step-by-step explanation:

We are asked to write an expression that shows the multiplication of 7\times 256 using expanded form and the distributive property.

First of all, we will write 256 in expanded form as:

256=200+50+6

Now, we will multiply 7 by (200+50+6) as:

7\times (200+50+6)

7\times 200+7\times 50+7\times 6

Therefore, our required expression would be 7\times 200+7\times 50+7\times 6.

Aaron is at a spot in his book where the page numbers of the two facing pages have a product of 1980 what are the two page numbe
Alona [7]
Basically you know that they are 2 consecutive numbers whose product is 1980. 
<span>n*(n+1)=1980 </span>
<span>n^2 + n - 1980 = 0 </span>
<span>(n -44)(n + 45)= 0 </span>
<span>n=44 </span>
<span>so the 2 page numbers is 44 and 45. </span>

<span>The faster way is just to take the square root of 1980 and since that is 44.497 you can conclude that the 2 numbers is below and above it (44, 45)</span>

Veronika [31]
To solve you first need to pick out the most important information,
~Spent 20 minutes 
~Each prob takes 2 minutes
Lets have y be the total time spent, and x the number of probs
(y/2) = x
Hope this helped!! ^-^

Write the slope intercept form of the equation of the line through the given point
ozzi

Answer:

y =  -\frac{3}{4}x

Step-by-step explanation:

slope-intercept form: y = mx + b

Given: slope(m) = -\frac{3}{4}, point (4, -3)

We already have the value of m, but we need to find the value of b. To do this, input the given values of the slope and the point into the equation:

-3 =  -\frac{3}{4}(4) + b

Solve for b:

-3 =  -\frac{3}{4}(4) + b

-3 = -3 + b

0 = b

The value of b is zero. We can now write the equation:

y =  -\frac{3}{4}x + 0

y =  -\frac{3}{4}x

The equation written in slope-intercept form is: y =  -\frac{3}{4}x
