Answer: 27/65
Step-by-step explanation:
Write the following expression in simplest form.
(3 + 16.4a) − (9 + 5.7a)
22.1a + (−12)
1.07a + (−12)
22.1a + (−6)
10.7a + (−6)
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.

Answer:
3.85 x 10 ^4
Step-by-step explanation:
The average number of viewers over the two weeks is 3.85 x 10 ^4
The given parameters are:
Week 1 = 3.6 x 10 ^4 viewers
Week 2 = 4.1 x 10 ^4 viewers
The average is calculated as:
Average = (Week 1 + Week 2)/2
This gives-
Average = (3.6 x 10 ^4 + 4.1 x 10 ^4)/2
Evaluate the sum:
Average = (7.7 x 10 ^4)/2
Evaluate the quotient:
Average = 3.85 x 10 ^4

Which expression is equivalent to 4(2.61y − 3.08)?
A - 10.44y + 3.08
B - 10.44y − 3.08
C - 10.44y + 12.32
D - 10.44y − 12.32
Answer: B
I am like 99% sure this is correct if not let me know
The equivalent expression is indeed 10.44y - 12.32 (option d).
let's break down the process of distributing the 4 to both terms inside the parentheses step by step:
Given expression: 4(2.61y - 3.08)
Distribute the 4 to both terms inside the parentheses:
4 * 2.61y - 4 * 3.08
Multiply 4 by 2.61y:
10.44y
Multiply 4 by 3.08:
-12.32
Now, putting it all together, the distributed expression becomes:
10.44y - 12.32
Therefore, after distributing the 4 to both terms inside the parentheses, the equivalent expression is indeed 10.44y - 12.32. This matches option D - "10.44y - 12.32".

You have been hired by your neighbor to babysit their children on Friday night. You are paid $8 per hour.
Based on the table, is the pay proportional to the hours worked?
Yes
No
Answer:
Yes
Step-by-step explanation:
For every hour you will be earning $8.
On the table if you divide the dollars by the hour worked you will receive $8.
Therefore it must be correct
Answer:
Yes
Step-by-step explanation:
Divide the Pay by the Hours Worked to solve how many dollars you are earning per hour.
8/1 = 8 dollar per hour
16/2 = 8 dollars per hour
24/3 = 8 dollars per hour
32/4 = 8 dollars per hour
36/4.5 = 8 dollars per hour
40/5 = 8 dollars per hour

An albatross is a large bird that can fly 400 kilometers in 8 hours at a constant speed. Using d for distance in kilometers and t for number of hours, an equation that represents this situation is d = 50t.
Write another equation that relates d and t in this context. [A]
Ill give brainliest answer
Fast please have 1 minute
Answer:
Step-by-step explanation: We are given relation between distance (in kilometers) travelled and number of hours taken by an Albatross bird.
Distance in kilometers taken by variable d.
Number of hours by t.
And situation is given d=50t.
We know, direct relation formula y= kx read as y is directly proportional to x. And k is the constants of proportionality.
In the given fuction y is taken by variable d and x is taken by variable t.
If we compare d=50t by y = mx, the value of k is 50.
Therefore, constant of proportionality is 50.
Constant is a number that never change it's value.
Therefore, constant of proportionality is just 50.
But we can say variables d and t are two variables those are directly proportional to each other.
Constant of proportionality is actually unit rate of change.
For the given situation constant of proportionality is the number of km travelled in per unit time (in 1 hour.)
If we divide 400km 8 hours, we get 400/8 = 50 km per hour.
Therefore, variables of proporation are d and t and relation between them is " they are directly proportional to each other".
And the constants of proportionality is just 50.
