The work of a student to solve a set of equations is shown:Equation 1: m = 8 + 2n
Equation 2: 3m = 4 + 4n

Step 1:
−3(m) = −3(8 + 2n) [Equation 1 is multiplied by −3.]
3m = 4 + 4n [Equation 2]

Step 2:
−3m = −24 − 6n [Equation 1 in Step 1 is simplified.]
3m = 4 + 4n [Equation 2]

Step 3:
−3m + 3m = −24 − 6n + 4n [Equations in Step 2 are added.]

Step 4:
0 = −24 − 2n

Step 5:
n = −12

In which step did the student first make an error?

Step 1

Answers

The student first makes an error in the Step 3 where he addsequations in Step 2 to use the elimination method.

What is the elimination method?

To create an equation in one variable using the elimination method, you can either add or subtract the equations. To eliminate a variable, add the equations when the coefficients of one variable are in opposition, and subtract the equations when the coefficients of one variable are in equality.

How to solve this problem?

Notice that the student uses the elimination method to solve the equations. In Step 1, he makes the coefficients of m equal in both equations. In Step 2, he simplifies the previous step. In Step 3, he wants to add both equations to create an equation in one variable. But He forgot to add 4 of Equation 2. It's a mistake.

Therefore the student first makes an error in the Step 3 where he addsequations in Step 2 to use the elimination method.

How to work out 280 times 380

Answers

2 8 0
x 3 8 0
0 0 0
2 2 4 0
+ 8 4 0
1 0 6 4 0 0

So, 280 x 380 = 106400

Here is another way
1st- put the #'s on top of each other
280
380
2nd- since both of them have 0's when done just add two 0
3- take out zeros HAVE TO BE AT END OF #
4- now ur problem is 28 • 38
5- put #'s on top of each other

ind the equation of a line perpendicular to y - 3x = – 8 that passes through the point (3, 2). (answer in slope-intercept form)

Answers

we have that
Find the equation of a line perpendicular to y - 3x = – 8 that passes through the point (3, 2)
y - 3x = – 8-----> y=3x-8------> the slope m=3

we know that
if two lines are perpendicular
then
m1*m2=-1
m1=3
so
m2=-1/3

with m=-1/3 and point (3, 2) find the equation of the line
y=mx+b
2=(-1/3)*3+b------> 2=-1+b-----> b=3

the equation of the line is
y=(-1/3)x+3

the answer is
y=(-1/3)x+3

Fred works for $8.75 per hour. His regular hours are 40 hours per week and he gets time and a half for overtime. One week he works 47.5 hours. He wants to calculate his pay.

Answers

For the first 40 hours, he gets 8.75/hour, so 40*8.75 = 350. For the last 7.5 hours, he gets (8.75*1.5)/hour. 8.75*1.5 = 13.125/hour, or 13.13/hour. Then do 13.13/hour * 7.5 hours = 98.48. Now add together 350 and 98.48. That equals $448.48 total for the week

Answer:

350, 13.13/hour, 98.48, 448.48.

Step-by-step explanation:

It's not clear where the answer is above, so I found it and put it here.
