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".

Answer:

Step-by-step explanation:

If triangle ABC is translated 2 units up and 2 units right, that means that all the vertices of the triangle are translated by the same units 2 up and 2 right.

The angle sum property of a triangle;

80 + 26 + B = 180

B = 180 - 106

B = 74

So, the answer is 74  degrees.

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:

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.

Answer: The answer for 4 is 7 and for 6 it's 14 and the slash means to divide

Step-by-step explanation: (14-9)+2 first solve the parentheses then the outside so 14-9 would be 5 and you would 5+2 which then equals 7. then for the second we do the same solve within the parentheses 8+6 equals 14/ 2-1 then we subtract and have 14/1 and anything divided by 1 stays the same which equals 14.

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
