The work of a student to solve the equation 4(2x − 4) = 8 + 2x + 8 is shown below:


Step 1: 4(2x − 4) = 8 + 2x + 8

Step 2: 6x − 8 = 16 + 2x

Step 3: 6x − 2x = 16 + 8

Step 4: 4x = 24

Step 5: x = 6



In which step did the student first make an error and what is the correct step?


Step 2; 8x − 4 = 2(6 + x + 6)

Step 2; 8x − 16 = 16 + 2x

Step 3; 6x − 2x = 16 − 8

Step 3; 6x + 2x = 16 + 8

Answers

Step 2; 8x-16 = 16+2x

Step-by-step explanation:

kiran and clare live 24 mile away from each other along a rail trail. One Saturday the two friends started walking toward each other along a trail at 8:00 am with a plan to have a picnic when they meet if kiran walks 3 miles per hour while clare walks 3.4 miles per hour. At what time will the two friends meet and have their picnic

Answers

Answer:

11:45

Step-by-step explanation:

Total distance between Kiran and Clare is 24 miles. They started walking at 8.00 am.

Speed of Kiran is 3 miles/hr and speed of Clare is 3.4 miles/hr.

So the relative speed of them is,

miles/hr

Both the speed are added as they moving in opposite direction.

We know that,

i.e

Putting the values,

As they started at 8.00 am, so the time at which will meet will be,

Step-by-step explanation:

apparently this is explains to find the linear function by the table ( given) but in slope intercept form ( please help me :') )

Answers

Answer:

y=4x+3.....hope this helps ; )

Step-by-step explanation:

Answer:

y = 4x +b

Step-by-step explanation:

The question asks you to write in slop intercept form which is y = mx+b so first you ahve to solve for the slope (m) and the formula for that is m = y2-y1/x2-x1

and bascially you plug in any points that are on the table and use the y's and x's

so im going to use the first two points

m =  (11-7) / (2-1)

   = 4 / 1

   = 4

so the slope equals four and we can plug that into our slope intercept equation

y = 4x + b and now we need to slove for b the y intercept and we can do that by plugging in any points from the table into our equation (to understand why this works probaly ask you teacher for a in-depth explination)

im going to use the first points again and plug it into our equation

7 = 4(1) + b (mutiply 1 by four)  

7 = 4 +b (isolate b so subtract four from each side)

-4   -4

3 = b so we now know the slope and the y intercept so our equation in slope intercept form will be y = 4x +3

Yolanda is filling her bathtub. The table shows the number of gallons of water in the bathtub at different times since she started filling it. Time (minutes) 1, 1.5, 2 Water (gallons) 16.50, 24.75,33. Now find the constant of proportionality (in gallons per minute) for the second and third rows of the table. Show your work.

Answers

Answer:

K= 16.5 gallons per minute

Step-by-step explanation:

Time t (minutes) Water g (gallons)

For t= 1, g= 16.50,

for t= 1.5 ,g= 24.75

For t= 2,g= 33

Let the function be

Gallons g= k(time t)

Where k is the constant of proportionality

16.5= k(1)for when t= 1

24.75= k(1.5) ..for when t= 1.5

Solving gives

8.25=k(0.5)

8.25/0.5= k.

16.5 = k

K= 16.5 gallons per minute

Question: (10-2)+(5x293)+(82x90)-2938

Answers

Answer:

5915

Step-by-step explanation:

Ok, so in 5th grade, we were taught to use PEMDAS (parentheses, exponents, multiplication, division, addition, subtraction), to get a long question correct. It has to be in that order, so start with parentheses. Here is the whole equation simplified: 8+1465+7380-2938. Now you will go from left to right. So, you have 1473+4442. And last, simplify, 1473+4442=5915. Hopefully this helped and if it did please mark it brainliest.

Answer:

5,915

Step-by-step explanation:

PEMDAS

P= Paranthesis:

(10-2)= 8

(5x293)=1,465

(82X90)=7,380

Then: AS add and subtract

8+1,465+7,380-2938=
