12.35y + 2.03
12.35y − 2.03

Answers

Answer 1

Answer:

b) 12.35y − 10.15

Step-by-step explanation:

Given equation,

→ 5(2.47y − 2.03)

The equivalent expression is,

→ 5(2.47y − 2.03)

→ 12.35y − 10.15

Hence, option (b) is correct.

Answer 2

Answer:

[tex]\bf 12.35y-10.15[/tex]

Step-by-step explanation:

[tex]\sf 5(2.47y - 2.03)[/tex]

Which expression is equivalent to 4(−3.7b − 3.1) − (4b + 0.4)?

A - 18.8b + 2.7
B - −18.8b − 2.7
C - 18.8b − 12.8
D - −18.8b − 12.8

Answers

4(-3.7b) = (-14.8b), 4(-3.1) = (-12.4)

(-14.8b - - 3.1) = (-14.8b + 3.1)

(-14.8b + 3.1) - (4b +0.4) = (-18.8b - 12.8)

Your answer is C and D. — (I’m assuming you meant to put a plus sign in either C or D so make sure you do the one with the negative sign for -12.8)

Answer:

Step-by-step explanation:

What I did: I put 17,172 over 55,208 as a fraction and to get the percentage I compared the denominator to 100, after this you multiply 17,172 by 100 then divide that by 55,208 to get 31.1316147 which rounds out to 31, once you put that over the 100 that is the percentage ( I may not have explained it the best way possible or the most efficient method, but thats how I got my answer ).

No, the slope with the equation is 1/5 and the slope of the table is 2/1  or 2

Step-by-step explanation:

Slope is the change in y over the change in x.

Equation

y = mx + b when an equation is written in the slope intercept form of a line, the m is the slope.

y = [tex]\frac{x}{5}[/tex] - 3  can be writing

y = [tex]\frac{1}{5}[/tex] x - 3  It is easier to see that the slope is [tex]\frac{1}{5}[/tex]

Table

Look at the y's.  The are change by 2 each time.  Now, look at the x's.  They are changing by 1 each time.  So, the slope is:

[tex]\frac{2}{1}[/tex] or just 2

The slope with the equation is 1/5 and the slope of the table is 2/1 or 2

Given statement solution is :- The median is the middle value when the data is arranged in ascending order. Since we have an even number of values (10 in total), the median is the average of the two middle values. In this case, the middle values are 3 and 4. Therefore, the median is (3 + 4) / 2 = 3.5 pounds.

To find the median of the given data set, we need to arrange the values in ascending order:

0, 0, 1, 2, 3, 4, 4, 5, 7, 8

The median is the middle value when the data is arranged in ascending order. Since we have an even number of values (10 in total), the median is the average of the two middle values. In this case, the middle values are 3 and 4. Therefore, the median is (3 + 4) / 2 = 3.5 pounds.

Answer: x=16

Step-by-step explanation:

Knowing that the sideways lines are parallels, the corner of them are equal to each other. Using this information, we can create an equation.

6x-12=4x+20

2x-12=20

2x=32

x=16.

Answer= 16

6x-12=4x+20 then you subtract 4 from 6 because they have the same variable which gives you..
2x-12=20 then you distribute the 12. so 12+12 cancels out and then 20+12 gives you 32 so..
2x=32 then you divide both sides by 2 which gives you..
