For the data in the table, does y vary directly with x? If it does write an equation for the direct variation. x 2 6 10 y 5 15 25
Answers
2 + 4 = 6 5 + 10 = 5
6 + 4 = 10 15 + 10 = 25
The proof is that everytime we increase x by a number (in this case 4), y also increases by some number (in this case 10);
So increasing x by 4, we increase y by 10;
The equation of data that shows direct proportionality is that of a line;
The gradient (represented by m) of the line is going to be how much y changes when we change x;
Using the information above, we can deduce the gradient (m) like so:
m = +10/+4
= 5/2
Now, we use the formula for the equation of the line:
y - y₁ = m(x - x₁)
y - 5 = 5/2(x - 2)
2(y - 5) = 5(x - 2)
2y - 10 = 5x - 10
2y = 5x
y = 5x/2

Final answer:
To compare the numbers 125%, 6/5, and 1.22, they were all converted to decimal form which revealed the least to greatest order as 1.22, 6/5, and 125%.
Explanation:
To arrange the numbers 125%, 6/5, and 1.22 from least to greatest, we first need to express all of them in the same format for an accurate comparison. Let's convert each number to a decimal:
125% as a decimal is 1.25 (since 100% is equal to 1, hence 125% is 1.25).6/5 as a decimal is 1.2 (6 divided by 5 equals 1.2).1.22 is already in decimal form.Now, we can easily compare:
1.226/5 (1.2)125% (1.25)The arrangement from least to greatest is 1.22, 6/5, 125%.

Answers
Answer: 25.8 kilometers
Step-by-step explanation:
Given: One kilometer = 0.62 miles
Then, [tex]1\text{ mile}=\dfrac{1}{0.62}\text{ kilometers}[/tex]
Then to find the number of kilometers in 16 miles, we need to multiply 16 to [tex]\dfrac{1}{0.62}[/tex], we get
[tex]\text{ 16 miles =}16\times\dfrac{1}{0.62}=25.806451612\approx25.8\text{ kilometers}[/tex]
Hence, 25.8 kilometers equals to 16 miles.

Answers
Last year Milwaukee had the total of snow amounting to 92 inches . The normal fall is 52 1/4 inches . How much above normal was the snowfall last year .
Answers
The snowfall in Milwaukee last year was 39.75 inches above the normal amount, calculated by subtracting the normal annual snowfall from last year's total.
Explanation:The student's question is related to subtraction of two amounts to find the difference between the actual snowfall and the normal snowfall in Milwaukee.
To determine how much above normal last year's snowfall was, we subtract the normal snowfall amount from last year's total snowfall.
Last year's snowfall in Milwaukee = 92 inches
Normal annual snowfall = 52 1/4 inches
To find how much above normal the snowfall was, we calculate:
92 inches - 52 1/4 inches = 92 inches - 52.25 inches
This equals 39.75 inches above normal snowfall.
Which represents the solution set of 5(x+5)<85?
A.) x<12
B.) x>12
C.) x<16
D.) x>16
Answers
YOUR answer is x<12
__________________________________________________
Given:
__________________________________________________
" 5(x + 5) < 85 " ; Simplify/ solve for "x" ;
__________________________________________________
Method 1)
__________________________________________________
Note the "distributive property of multiplication" :
__________________________________________________
a(b + c) = ab + ac ;
a(b – c) = ab – ac .
__________________________________________________
So, take the "left-hand side" of the inequality; and expand:
__________________________________________________
→ 5(x + 5) = (5*x) + (5*5) = 5x + 25 ;
Now, rewrite the inequality:
→ 5x + 25 < 85 ;
Subtract "25" from each side of the inequality ;
→ 5x + 25 – 25 < 85 – 25 ;
to get:
_______________________________________
→ 5x < 60 ;
Divide each side of the inequality by "5" ;
→ 5x / 5 < 60 / 5 ;
→ x < 12 ; which is: Answer choice: [A]: " x < 12 " .
_______________________________________
Method 2)
_______________________________________
Given:
_______________________________________
" 5(x + 5) < 85 " ; Simplify/ solve for "x" ;
_______________________________________
Divide EACH SIDE of the equation by "5" ;
[5(x + 5) ] / 5 < 85 / 5 ;
to get:
→ x + 5 < 17 ;
Subtract "5" from EACH SIDE of the inequality:
→ x + 5 – 5 < 17 – 5 ;
to get:
→ x < 12 ; which is: Answer choice: [A]: " x < 12 " .

the standard addition algorithm below is being used to add three two-digit numbers 4z + 27 + x 5 equals y 14. If x, y, and z each represent a different digit from 0 to 9 what is the value of (x)(y)(z)?
Answers
[tex]z+7+5=4 \\ z+12=4[/tex]
From this we can conclude that total sum of these three numbers is 14. Number 1 we carry to next step. So we have:

For the tens positions of all numbers we have:
[tex]4+2+x+1=1 \\ 7+x=1[/tex]
The extra number 1 on left side comes from the carry from last step. Similar to ones position we know that total sum is 11.
[tex]7+x=11 \\ x=4[/tex]

The perimeter of a rectangle is 80 feet. Find the demensions if the length is 5 feet longer than four times the width. Then find the area of the rectangle.
-Show All Work!-
Answers
The first thing we should do is review the formulas for area and perimeter.
Perimeter can be expressed in two ways: a) l+w+l+w OR b) 2l+2w.
The formula for area is: l*w
We know that the length is 5 feet longer than the width, so when we're defining our variables we can say that width is equal to 'w', and length is equal to 4w+5.
Since we know that the perimeter is equal to 80, we can say that [tex]80= 2(4w+5) + 2(w)[/tex].
Now all we have to do is combine like terms and solve for 80:
[tex]80 = 2(4w+5) +2w [/tex]
[tex]80 = 8w + 10 +2w[/tex]
[tex]80 = 10w +10[/tex]
[tex]80-10 = 10w +10 -10[/tex]
[tex]70 = 10w[/tex]
[tex] \frac{70}{10} = \frac{10w}{10} [/tex]
[tex]7 = w[/tex]
We now know that the width is equal to 7 feet. To find the length, we can substitute the width into 4w+5:
[tex]l = 4w + 5 = 4(7)+5[/tex]
[tex]l = 28 + 5[/tex]
[tex]l = 33[/tex]
Now we know that the length is equal to 33 feet.
So there's your dimensions: 7ft by 33 ft.
Next, to find the area, we take l*w
[tex]33*7 = 231ft^{2} [/tex]

A student's cell phone plan has a monthly charge of $40 for 600 minutes of use and a $0.25/minute charge for each additional minute. Last month, the student talked on the phone for 790 minutes. Which of the following is the bill for the month?
Answers
The bill for the month is $87.50, including $40 for 600 minutes and $47.50 for 190 extra minutes.
To calculate the bill for the month, we need to consider the fixed monthly charge and the additional charge for the extra minutes used beyond the 600-minute limit.
Step 1: Calculate the additional minutes used beyond the 600-minute limit:
Total minutes used - Included minutes = Extra minutes
790 minutes - 600 minutes = 190 extra minutes
Step 2: Calculate the additional charge for the extra minutes:
Extra minutes × Additional charge per minute
190 minutes × $0.25/minute = $47.50
Step 3: Add the fixed monthly charge to the additional charge for the extra minutes:
Fixed monthly charge + Additional charge for extra minutes
$40 + $47.50 = $87.50
So, the bill for the month is $87.50.

3 3/5
Step-by-step explanation:
covert mixed fractions to improper fractions
2 2/3 becomes 8/3
1 1/8 becomes 9/8
1 1/5 become 6/5
then you multiply across will give you 432/120
since the numerator os greater than the demoninator, you have to divide 432
into 120 which then will give you 3 72/120. When you simplify the fraction the final answer is 3 3/5.
