on a shopping trip gill spends 1/3rd of his money in store A then he spends 1/3 of money he has left in store B. Finally he spends his remaining $12 in store C. How many dollars did he have at the start?
Answers
Answer:
$18
Step-by-step explanation:
Let the money he had at the start be $x
Store A = 1/3 of $x = $ x/3
Remaining = $ x/1 - $x/3 = $ 2x/3
He spends remaining $12. So,
2x/3 = 12
2x = 36
x= $18(Answer)

the school decided to raise the price lunches by $0.25. Seth buys the school lunch 5 days a week. Write a formula that will help seth determine how much he'll now spend on lunch every week.
p= old price of school lunch
t= total seth pays for lunch each week
Answers
Seth can calculate his weekly lunch expenses with the formula t = 5 x (p + $0.25), where p is the old price and t is the new weekly total.
The question involves creating a formula that Seth can use to determine how much he will spend on lunch every week after an increase in the price.
Let's define the following variables: p for the old price of school lunch and t for the total Seth pays for lunch each week.
If the school decided to raise the price of lunches by $0.25 and Seth buys the school lunch 5 days a week, the new price of each lunch will be p + $0.25.
Therefore, to calculate the total Seth will pay per week, we use the formula: t = 5 x (p + $0.25).
This formula accounts for the new price Seth will pay for lunch each day, multiplied by the 5 days he purchases lunch at school.

Lou cuts 3 yards from a 9 yard roll of fabric. Then he cuts 4 feet from the roll. How many feet of fabric is left on the roll.
Answers
Would be Correct
please mark me as brainliest
Final answer:
Lou starts with a roll of fabric that's 9 yards long which equals 27 feet (9 yd x 3 ft/1 yd). After cutting 3 yards (9 feet) and then 4 feet, he's left with 14 feet of fabric.
Explanation:
The question involves calculating the remaining length of fabric in feet after Lou makes two cuts from a roll. Since one yard is equivalent to 3 feet, we'll first convert the roll's total length from yards to feet. Starting with a 9-yard roll, we convert it to feet (9 yd x 3 ft/1 yd = 27 ft). After cutting 3 yards (which equals 9 feet) and then another 4 feet, we subtract these from the total length.
Here's the step-by-step calculation:
Convert initial length to feet: 9 yd x 3 ft/1 yd = 27 ft.
Subtract the first cut in feet: 27 ft - 3 yd (9 ft) = 18 ft remaining.
Subtract the second cut: 18 ft - 4 ft = 14 feet remaining.
Therefore, there are 14 feet of fabric left on the roll.

The sum of 5 consecutive integers is 270
Answers
______________________________________________________
The expression is written as:
________________________________________________
x + (x + 1) + (x + 2) + (x + 3) + (x + 4) = 270 ;
________________________________________________
in which the 5 (FIVE) consecutive integers are:
________________________________________________
x, (x + 1), (x + 2), (x + 3), (x + 4) .
________________________________________________
To find the 5 (FIVE) consecutive integers, we solve for "x" , and the plug in the the value of "x" for the expressions of the other integers.
________________________________________________
We have:
________________________________________________
x + (x + 1) + (x + 2) + (x + 3) + (x + 4) = 270 ;
________________________________________________
Rewrite as:
________________________________________________
x + x + 1 + x + 2 + x + 3 + x + 4 = 270 ;
________________________________________________
Combine the "like terms" on the "left-hand side" of the equation:
________________________________________________
x + x + x + x + x = 1x + 1x + 1x + 1x = 1x = 5x ;
1 + 2 + 3 + 4 = 10 ;
________________________________________________
→ 5x + 10 = 270 ;
Subtract "10" from each side of the equation;
5x + 10 − 10 = 270 − 10 ;
to get:
5x = 260 ;
Divide EACH SIDE of the equation by "5" ;
5x / 5 = 260 / 5 ;
to get:
x = 52 ;
____________________________________
x = 52 ;
x + 1 = 52 + 1 = 53 ;
x + 2 = 52 + 2 = 54 ;
x + 3 = 52 + 3 = 55 ;
x + 4 = 52 + 4 = 56 ;
___________________________
The 5 (FIVE) consecutive integers are: 52, 53, 54, 55, and 56 .
________________________________________________
Let us check our answer:
________________________________________________
52 + 53 + 54 + 55 + 56 =? 270 ?
________________________________________________
52 + 53 = 105;
105 + 54 = 159 ;
159 + 55 = 214 ;
214 + 56 = 270 ;
→ 52 + 53 + 54 + 55 + 56 =? 270 ? Yes!

To cover A rectangle region of her yard penny needs atleast 170.5 square feet of sod. The length of the region is 15.5 feet. What are the possible widths of the region? Write an inequality and solve. I know the answer is 11, but how would you write the inequality?
Answers
Let w = the width of the rectangular area.
Because the length is 15.5 ft, therefore the calculated area should be at least 170.5 ft². That is
(15.5 ft)*(w ft) ≥ 170.5 ft²
w ≥ 170.5/15.5
w ≥ 11 ft
Answer: w ≥ 11 ft

0.06 or 60% which is greater?
Answers
Final answer:
When comparing 0.06 and 60%, we need to convert the percentage to a decimal (0.60) to make a direct comparison. 0.60 is greater than 0.06.
Explanation:
To compare 0.06 and 60%, first, we should express both numbers in the same format. The number 0.06 is already in decimal form, so let's convert 60% into a decimal. To do this, we divide 60 by 100, which equals 0.60. Now we can see that 0.60 is greater than 0.06.

y-2/3=-2(x-1/4)
y-2/3=-2x+1/2
y=-2x+(3/6+4/6)

[tex]y=mx+c[/tex]
The given equation of a line :[tex]y-\dfrac{2}{3}=-2(x-\dfrac{1}{4})[/tex]
To convert it into slope-intercept form , we need to multiply -2 inside the brackets , we get
[tex]y-\dfrac{2}{3}=-2x-\dfrac{-2}{4})\\\\\Rightarrow y-\dfrac{2}{3}=-2x+\dfrac{1}{2}\\\\\Rightarrow y=-2x+\dfrac{1}{2}+\dfrac{2}{3}\\\\\Rightarrow\ y=-2x+\dfrac{7}{6}[/tex]
Hence, the equation in slope-intercept form : [tex] y=-2x+\dfrac{7}{6}[/tex]
