22.1a + (−12)
1.07a + (−12)
22.1a + (−6)
10.7a + (−6)
Answers
Answer:
10.7a + (−6)
Step-by-step explanation:
Let's simplify step-by-step.
3+16.4a−(9+5.7a)
Distribute the Negative Sign:
=3+16.4a+−1(9+5.7a)
=3+16.4a+(−1)(9)+−1(5.7a)
=3+16.4a+−9+−5.7a
Combine Like Terms:
=3+16.4a+−9+−5.7a
=(16.4a+−5.7a)+(3+−9)
=10.7a+−6
Option D is correct. The expression in its simplest form is: 10.7a - 6.
Let's simplify the given expression:
(3 + 16.4a) − (9 + 5.7a)
Distribute the negative sign to the terms inside the second parentheses:
(3 + 16.4a) − 9 − 5.7a
Combine like terms:
(16.4a - 5.7a) + (3 - 9)
Perform the subtraction and subtraction of coefficients:
(16.4a - 5.7a) + (-6)
Simplify the expression:
(10.7a) - 6
So, the expression in its simplest form is: 10.7a - 6. Option D is correct.

A rural mail carrier logged the mileage on the odmeter at the start of th mail route as 31,500 miles. After 6.5 hours the carrier returned the truck recorded the mileage at 31,713 miles what was the average velocity of the mail truck
Answers
Answer:
Okay, So rural mail carrier started the day with 31,500 miles 6.5 hours later has 3, 31,613 miles. So if you want the average velocity of the mail truck over this day, we're going to start, we're going to find basically the treat the average velocity as a slope. So we're gonna do is we're gonna do the final three hoops, 31,713 -231500. This will be the total distance that they traveled And that happened over 6.5 hours. So 31,613 -31500 is going to give me 213 over 6.5 hours. So what this represents is The truck went 213 miles Over the course of 6.5 hours. So again, that's miles over ours. So I take that value Divide by 6.5 and I get Average velocity of 30 32 Point that's just a 77. Okay. And again, because I had it set up as miles over hours, this is gonna be MPH. So this is where we find the average velocity of something. We're looking at, what was it at the very end. Now, the truck went faster and slower than this speed at times, But in the end because it covered two and 13 miles in 6.5 hours, The average velocity was 32.77 mph

6) A square wall has a area of 256 square inches. What is the length of one side of the wall?
Show work!
Answers
We need to find the square root of what we’re given here. The square root of a number is the number that can be multiplied by itself to receive the resulting number (which is 256 in this case).
√256 = 16 because:
16 • 16 = 256
The length of one side of the wall is 16 inches.
Answer:
16
Step-by-step explanation:
Since the area is 256 square inches and it is a square
Finding the square root would give us the answer as area of square is side*side
So one wall= √256=16

Answers
The scale 15 ft to 1 unit from the deck to the drawing will give a perimeter of 8 units.
How to calculate the scale?From the information, the actual deck has a perimeter of 120 ft.
Therefore, another scale drawing of the deck using the scale 15 ft to 1 unit from the deck to the drawing will be:
