Answer: 2.8%
Step-by-step explanation:
Give, In a certain month a family spent $750 on food
In third month the family spent $729 on food .
i.e. Expenditure on food in a certain month = $750
Expenditure on food in third month = $729
Decrease in monthly spending on food = (Expenditure in a certain month )- (Expenditure in third month )
= $750 - $729
= $21
Now , the percentage decrease in the month spent on food will be :
Hence, the percentage decrease in the month spent on food is 2.8%.
Hello
<span>an equation for the line in point-slope form and general form is :
y = ax+b a : </span>slope ; the <span>Passing through (x' ; y')
</span>y' = ax'+b
y-y' =a(x-x') and : x' =8 y' = -4
calculate a :
let : y = ax+b .....(D)
....(D') y = (1/5)x+4
.(D) perpendicular to(D') : slope (D) × slope (D') = -1
slope (D') = 1/5
slop(D)×(1/5) = -1
slope (D) = -5
equation for the line : y-y' =a(x-x')
y+4 =(-5) (x-8)
Answer:
Step-by-step explanation:
Given:
The given AP is.
12,0,-12,......
The first term of an AP 
Common difference 
We use the the formula for nth term of an AP.
for 87th term
Therefore, The 87th term of given series is -1020.
Tim would have to do 18 chores (2 chores 9 times or 1 chore 18 times) to be able to buy the video game.
Step-by-step explanation:
Step 1; Tim's parents will give him $3 for every two chores. This equals $1.50 for a single chore. He wants to save up $27 so that he can buy the video games he wants.
Step 2; The number of times he has to do the chores to be able to but the video game is a division between the money he wants to save up by the money he gets for the chores.
Number of 2 chores he needs to do = Amount of money he wants to save up / money he gets for doing two chores
= $27 / $3 = 9 times.
Number of single chores he has to do =Amount of money he wants to save up / money he gets for doing two chores
$27 / $1.50 = 18 times
6x-3 is the answer because you multiply an invisible 1 by bothering the -6x and 3
