Which equations illustrate the associative property of addition? Choose exactly two answers that are correct. A. (11 + 2.2) + (–5) = 11 + [2.2 + (–5)]
B. –3 • (5 + 8.5) = –3 • 5 + (–3) • 8.5
C. + 1.8 = 1.8 +
D. –7 + [4 + (–2.1 • 6)] = (–7 + 4) + (–2.1 • 6)

Answers

Answer 1
Answer: Solutions 

Associative Property is a rule that refers to grouping. The rule is "a + (b + c) = (a + b) + c". 

The correct answers are (A) and (D) 

(A) =  (11 + 2.2) + (–5) = 11 + [2.2 + (–5)] 

(D) = 
–7 + [4 + (–2.1 • 6)] = (–7 + 4) + (–2.1 • 6)

A line with a slope of -8 passes through the points (6,-1) and (w, 7). What is the value of w?

Answers

Answer:

The value of w is 5.

Step-by-step explanation:

To find the value of w, we start with the slope equation. Then, we input all of the values we are given.

m(slope) = (y2 - y1)/(x2 - x1)

-8 = (7 - -1)/(w - 6)

-8 = 8/(w - 6)

Now to solve for w, we need to cross multiply.

-8(w - 6) = 8

w - 6 = -1

w = 5

Final answer:

To find the value 'w', we use the equation for calculating the slope of a line given two points. After placing the known values into the equation, we solve for 'w' and find that w = 5.

Explanation:

To solve for w, we utilize the formula for the slope of a line given two points (x1, y1) and (x2, y2), which is (y2-y1)/(x2-x1). In our case, we know the slope is -8, and we have one point (6, -1) and another point (w, 7).

So, we set up the equation -8 = (7 - (-1)) / (w - 6). Simplifying this gives -8 = 8 / (w - 6). Cross multiply gives -8*(w - 6) = 8, which simplifies to -8w + 48 = 8. Subtracting 48 from both sides gives -8w = -40, so w = 5.

Estimate the sum of 196 + 482

Answers

The estimated sum of 196 and 482 is 700.

We do estimates when we do mental calculation. We relate the number to the nearest number that can easily be computed mentally.

196 is near 200 so we round it up to 200
482 is near 500 so we round it up to 500

Thus, 200 + 500 = 700.

700 is the estimated sum.

700 i think because 196 is close to 200 and 482 is close to 500 so 200+500=700 

Turn 0.46 into a fraction

since you would say 0.46 as forty six hundredths, then you would write it as what it sounds like.

hope i helped!
You just put 46 over a number that is 10^2 
I got the two from the fact that there are two didgets after the decimal point 10^2 is 100 so 46/100=23/50. :D
