Answer:

Step-by-step explanation: Think back to your elementary days: how did you learn to round numbers? Chances are, your teacher taught the class how to round up or down from the number 5. In other words, if the last number is below five, you might round it down, and if it’s above, it gets rounded up.
In fact, there are a whole plethora of rounding rhymes that can easily be found on the internet. Complete a quick Google search, and you might find something like, “5 and above, give it a shove! 4 and below, let it go!”. While these sayings might seem like a great solution to help kids quickly learn to solve problems, how do children know what place value they are rounding to?
kids with scores
Before the current Common Core or individual state standards were established, mathematics was often taught by encouraging students to memorize facts and learn tricks to complete problems. Rounding is no exception, as many educators have encouraged kids to use rhymes like those described above. Needless to say, it doesn’t teach a child the underlying concept itself.
Below we’ll explore exactly why teaching math tricks don’t work, even if it helps students to arrive at a correct answer. Then, keep reading to discover 7 of the best ways to teach rounding numbers.
Why Getting Answers Correct is Not Enough
As mentioned above, teaching kids tricks or “hacks” to complete math problems can sometimes be helpful, it doesn’t help your child understand the mathematical concept behind the skill. For kids, teaching them to think about the number 5 and round up or down can help them arrive at the right answer, but they aren’t thinking about place value when they use the trick. So, if children are completing a rounding activity, they don’t know if they should round to the nearest ten or hundred. In fact, they might not know why they’re rounding up or down at all!

Write the equation of the line through the points (4, 5) and (12, 9)
Answers
Answer:
y = 1/2x + 3
Step-by-step explanation:
y2 - y1 / x2 - x1
9 - 5 / 12 - 4 = 4/8 = 1/2
y = mx+b
slope/m = 1/2
y = 1/2x + b
5 = 1/2(4) + b
5 = 2 + b
3 = b
y = 1/2x + 3
The equation of the line passing through the points (4, 5) and (12, 9) is x - 2y = -6
From the question,
We are to determine the equation of the line passing through the points (4, 5) and (12, 9)
Using the formula,
[tex]\frac{y-y_{1} }{x-x_{1}} = \frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]
From the given information
x₁ = 4
y₁ = 5
x₂ = 12
y₂ = 9
Putting the parameters into the formula, we get
[tex]\frac{y-5}{x-4} =\frac{9-5}{12-4}[/tex]
Then,
[tex]\frac{y-5}{x-4} =\frac{4}{8}[/tex]
[tex]\frac{y-5}{x-4} =\frac{1}{2}[/tex]
Then,
[tex]x - 4 = 2(y-5)[/tex]
[tex]x - 4 = 2y-10[/tex]
[tex]x -2y = -10 + 4[/tex]
[tex]x -2y = -6[/tex]
Hence, the equation of the line passing through the points (4, 5) and (12, 9) is x - 2y = -6

-12<x<-9/2Gail Martinez is employed at My Best Books. She has family medical coverage through the group medical plan that My Best Books provides for its employees. The annual cost of Martinez's family membership is $3,900. The company pays 50% of the cost. How much does she pay annually for medical insurance? *
Answers
Answer:
$1850
Step-by-step explanation:
The annual cost of Martinez's family membership for medical insurance is $3,900.
The company pays 50% of the cost.
So, the cost paid by the company= 50% of $3,900.
[tex]=\frac {50}{100}\times 3900=\$1850[/tex]
The remaining cost for the family medical insurance must be paid by Gail Martinez.
So, the annual payment by her =$3900-$1850=$1850
Hence, she pays $1850 annually for medical insurance.

Ben and Ella are filling goodie bags for a party. Each goodie bag needs an eraser, a bubble wand, and a few candy bar bites. Ben filled 25 goodie bags in 20 minutes. Ella filled 27 goodie bags in 24 minutes. Who filled goodie bags at a faster pace?
Answers
Answer:
Ben
Step-by-step explanation:
25 goodies = 20 minutes
27 goodies = 24 minutes
Let's use ratio, divide both of them by their minute
25/20 = 20/20
27/24 = 24/24
1.25 goodies = 1 minute
1.12 goodies = 1 minute
1.25 is bigger than 1.12.

y−1=−2(x−2) in slope intercept form
Answers
Answer:
[tex]y = - 2x + 5[/tex]
Step-by-step explanation:
Simply simplify the equation from what it is to the slope intercept format:
[tex]y = mx + b[/tex]
Step-by-step explanation:
Hey there!
We know;
The slope intercept form of equation is;
y = mx+c
So, let's try to take it in this form.
(y-1) = -2(x-2)
Multiply -2 and (x-2)
(y-1) = -2x + 4
Take '-1' to right side.
y = -2x+4+1
y = -2x+5
Therefore, the equation is y = -2x+5.

In the video game Fantasy Farm, it takes 5 6 6 5 start fraction, 5, divided by, 6, end fraction of a minute to harvest magic flowers, and it takes 5 6 6 5 start fraction, 5, divided by, 6, end fraction of an hour to build a golden barn. Which takes more time?
Answers
Answer:
Building gold barn takes more time
Step-by-step explanation:
Time to harvest magic flowers = 5/6 of a minutes
Time to build a gold barn = 5 / 6 of an hour
1 hour = 60 minutes
Time to build a gold barn = 5 / 6 of 60 minutes
= 5/6 × 60 minutes
= 50 minutes
= 50 minutes × 60 seconds
= 3,000 seconds
Time to harvest magic flowers = 5/6 of a minutes
1 minutes = 60 seconds
= 5/6 × 60 seconds
= 50 seconds
Building gold barn takes more time

The cost of 10 shoes is less than the cost of 4 shoes with a $2 off coupon. The cost of 10 shoes is less than the cost of 4 shoes with $2 socks. The cost of 10 shoes is less than the cost of 4 shoes with $2 socks. The cost of $2 is greater than the cost of 4 shoes.
Answers
Answer:
The cost of 10 shoes is less than the cost of 4 shoes with a $2 off coupon.
Explanation:
The inequality corresponds closely to the cost of 10 shoes being less than cost of 4 shoes with $2 off coupon. Closely because there is an error here the constant $2 off coupon should mean it is reducing the price of 4 shoes and therefore a minus sign should come before it, equation should be 10x<4x-2.
We can see that X is the price per shoe here
for how many tickets is the cost the same for club members and non-members?
Answers
Answer:
The cost will be the same for 2 club members as for 1 non-member.
Step-by-step explanation:
There will never be a number of tickets where the price for a given number of club members is the same for the same number of non-members.
However, if two club members purchase tickets, their cost is 2($3) = $6.
If one non-member purchases a ticket, the cost is 1($6) = $6.
