Andre tried to solve the equation 1/4 ( x + 12 ) = 2. What was his mistake? Explain.

1/4x = -10
x = -40

Answers

Andre’s first mistake was that he didn’t distribute properly or at all. Instead of using the distributive property to get rid of the parenthesis, he moved the x to the 1/4 and subtracted 12 to the other side. Mistakes continue to occur from there so the equation solved would be:
1/4 (x+12)=2
1/4x+3=2
1/4x=-1
x=-4

His mistake is that he does not open the bracket first. The value of the x is negative of 4.

What is a BODMAS rule?

BODMAS rule means for the Bracket, Order, Division, Multiplication, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

Andre tried to solve the equation 1/4 ( x + 12 ) = 2.

First, open the bracket, then we have

[tex]\dfrac{x}{4} + \dfrac{12}{4} = 2[/tex]

On simplifying, we have

[tex]\dfrac{x}{4 } + 3 = 2[/tex]

Subtract 3 from both sides, we have

[tex]\dfrac{x}{4} = -1[/tex]

Multiply the equation by 4, we have

[tex]x = -4[/tex]

More about the BODMAS rule link is given below.

"You figure you can ride Ghost Wind, then get on. Just bring him back to the stable when you're finished so I can rub him down." I dismounted, leaving the stallion with Mitchell, and headed toward the barn. Now, I truly expected that Mitchell would come after me with Ghost Wind. After all, despite my invitation, I knew Mitchell couldn't ride Ghost Wind. As far as I knew, Mitchell had never ridden more than a mule and had no idea how to ride a thoroughbred tornado like Ghost Wind. But instead of Mitchell following me, the next thing I knew, I heard a triumphant cry, turned, and saw Mitchell atop the stallion dashing across the meadow. For a moment all I could do was stand and stare. But then, as the stallion bucked, left the meadow, and headed for the woods, I suddenly found my legs and my voice, and I began running and screaming after Mitchell and the stallion. "Pull back the reins!" I hollered as I ran. "Mitchell, the reins! Pull back hard!" —The Land, Mildred D. Taylor Use the drop-down menus to answer the questions.

Answers

Answer: y=0.63x+12.5

sum of x = 260

sum of y = 288

mean x = 26

mean y = 28.8

sum of squares= 3000

sum of products= 1876

find the line of best fit or line of regression

regression equation = y = bx + a

b= 1876/3000 = 0.62533

a= 28.8 - (0.63*26) = 12.54133

then round and plug a and b into the equation

y=0.63x+12.5

you decide where to put the line by where the average or mean of the points are. there are clusters in the points which makes it easier to place the line of best fit. the outliers are the point scattered away from the line of best fit and the clusters are groups of point very closely put together.

A paper company needs to ship paper to a large printing business. The paper will be shipped in small boxes and large boxes. Each small box of paper weighs 35 pounds and each large box of paper weighs 65 pounds. A total of 22 boxes of paper were shipped weighing 1040 pounds altogether. Determine the number of small boxes shipped and the number of large boxes shipped.
HELP PLZ!!!!!

Answers

Number of small boxes shipped = 10

Number of large boxes shipped = 12

Step-by-step explanation:

Let x be the number of small boxes

and

y be the number of large boxes

According to the first statement, a total of 22 boxes were shipped

Equation 1 will be:

x+y=22

And

According to 2nd statement, Total weight was 1350 and we know the weight of one small box is 45 and large box is 75

So equation 2 will be:

45x+75y=1350

We will use the substitution method for solving the equation

So from equation 1

Putting the value of x in eqn 2

Putting the value of y in eqn 1

So,

Number of small boxes shipped = 10

Number of large boxes shipped = 12 ..
