Which equation is equivalent to I = prt?
A. P = I + rt
B. P = Irt
C. P = I - rt
D. P = I/rt
Answer: Choice D. P = i/rt
This is the same as saying P = i/(rt). The parenthesis are preferred in my opinion to indicate we have rt in the denominator and not just r.
======================================
Explanation:
In the original equation, prt is the same as p*r*t. So we multiply p, r and t to get prt.
This can be thought of as p*(rt). To isolate p, we undo the multiplication done to the variable p. We will divide both sides by rt to get
i = prt
i = p*(rt)
i/(rt) = p*(rt)/(rt) ... dividing both sides by rt
i/(rt) = p
p = i/(rt)

What is the quotient when 512 is divided by -8? Show your work!!
Answer:
-64
Step-by-step explanation:512 divided by 2 can be calculated as follows. 512/2 math problems division = 256. Therefore 256 to 2 decimal places= 256. 512/2
The quotient of the equation when A = 512 / -8 = -64
Given data ,
Let the quotient of the expression be represented as A
Now , the value of A is
Let the first number be represented as p
Now , the value of p = 512
Let the second number be represented as q
Now , the value of q = -8
where A = p/q
On simplifying the equation , we get
A = 512 / ( - 8 )
A = -512 / 8
A = -64
Therefore , the quotient of the expression is A = -64
Hence , the expression is A = -64

Lupe had $100 to buy party supplies for her little sister's birthday. She bought 12 bags of party favors and 15 party hats. Each bag of party favors cost $5.30, and each party hat cost $1.95. How much money did Lupe have left after her purchases? $7.15 $20.50 $36.40 $65.75
Answer:
He had 7.15 dollars left over
Step-by-step explanation:
12 x 5.3 = 63.6
15 x 1.95 = 29.25
63.6 + 29.25 = 92.85

The money left with Lupe after her purchase is $7.15.
Given,
Lupe had $100 to buy party supplies for her little sister's birthday.
She bought 12 bags of party favors and 15 party hats.
Each bag of party favors costs $5.30.
Each party hat cost $1.95.
We need to find how much money Lupe has left after her purchases.
How do we find the amount left after spending from the total amount?We will subtract the amount spent from the total amount given.
The number of spending may depend on the number of items bought and the cost of each item.
If one item cost = $a
And number of items bought = 2
The total amount spent = 2 x $a = $2a
Find the amount Lupe has.
= $100
Find the cost of one party bag.
= $5.30
Find the cost of one party hat.
= $1.95
Find the number of the party bags.
= 12
Find the number of the party hats.
= 15
Find the cost of 12 party bags.
= 12 x $5.30
= $63.6
Find the cost of 15 party hats.
= 15 x $1.95
= $29.25
Find the money left.
= $100 - ($63.6 + $29.25)
= $100 - $92.85
= $7.15
Thus the money left with Lupe after her purchase is $7.15.

The perimeter of a rectangle playing Field is 504 meters. It’s length is 6 meters shorter than twice it’s width. What is the area?
Answer:
Area = 14276
Step-by-step explanation:
Length = 2w-6
Width =w
perimeter = 2w+ 2l =504
2w+2(2w-6)=504
2w+4w-12=504
6w=516
w=86
L=2w-6
L=2(86)-6
L = 172-6
L = 166
Area = L*W

placed on the wall.
Workers

Bricks Placed
90
180
270
360
What’s the relationship
Answer:
[tex]b = 90w[/tex]
Step-by-step explanation:
Required
Determine the relationship
Represent the workers with w and bricks with b
First, we need to determine the constant of proportionality using:
[tex]b = kw[/tex]
Solve for k
[tex]k = \frac{b}{w}[/tex]
When w = 1; b = 90:
[tex]k = \frac{90}{1}[/tex]
[tex]k = 90[/tex]
When w = 2; k =180
[tex]k = \frac{180}{2}[/tex]
[tex]k = 90[/tex]
Notice that [tex]k = 90[/tex] in both cases;
Substitute 90 for k in [tex]b = kw[/tex]
[tex]b = 90w[/tex]
Hence; the relationship is [tex]b = 90w[/tex]
The coordinates of point J are (5, −6) and the coordinates of the point K are (7, 8).
What are the coordinates of the point one half the distance from J to K?
Answer:
The coordinates of the point one half the distance is (6,1)
Step-by-step explanation:
Here we want to calculate the coordinates one half of the line segment.
This in another way simply means the coordinates of the midpoint of that segment;
Mathematically;
we proceed with this using the midpoint formula
(x,y) = (x1 + x2)/2, (y1 + y2)/2
From the question (x1,y1) = (5,-6) while (x2,y2) = (7,8)
let’s say
(x,y) = (5 + 7)/2 , (-6 + 8)/2
(x,y) = 12/2, 2/2
(x,y) = (6,1)
Mr. Bins sold 1/2 of his farm to Mr. Frost and 100 acres to Mr. Slate. He now has 1/5 of his original farm land. How big was his farm originally? How much land does he have now? <3
Answer:
His original farm was 333 1/3 acres
He has 66 2/3 acres of his land left
Step-by-step explanation:
Lex
His total farmland = x
1/2 of x = Mr frost
100 acres = Mr slate
Remaining = 1/5x
His total farmland = Mr Frost + Mr slate + remaining farmland
x = 1/2x + 100 + 1/5x
x = 5x+2x/10 + 100
x = 7/10x + 100
x - 7/10x = 100
10x-7x/10 =100
3/10x = 100
Divide both sides by 3/10
x = 100 ÷ 3/10
= 100 × 10/3
= 1,000/3
= 333 1/3 acres
His original farm was 333 1/3 acres
He has 1/5 of his original farm
1/5 × 1000/3
= 1,000 / 15
= 66 10/15
= 66 2/3 acres
He has 66 2/3 acres of his land left

dont understand it, so yeah need some help
Answer:
-4
Step-by-step explanation:
We have the coordinates (6, 3) and (8, 4), allowing us to calculate the slope (or gradient). To do this, you divide the change in y by the change in x, which is 1/2 which is a half.
The form of a linear equation is y = mx + c, where m is the gradient and c is the y-intercept.
We have the gradient, so we can put it in the equation:
y = x/2 + c
We can now substitute in a pair of our coordinates and rearrange to find the y-intercept.
3 = 6/2 + c
3 = 3 + c
c = 0
Therefore the equation for our line is y = x/2.
We can now put in the y coordinate we were given to work out the corresponding x coordinate:
-2 = x/2
x = -4
Therefore n is -4.

Find three consecutive odd integers such as the sum of the smallest number and middle number is 27 less than 3 times the largest number
Answer:
17, 19 and 21Step-by-step explanation:
x - an integer
then: 2x is an even number and 2x+1 is an odd number
consecutive odd numbers increase by 2 (even numbers too)
so the next odd number (the middle number) is:
2x+1+2 = 2x+3
and the third (the largest) consecutive is:
2x+3+2 = 2x+5
the sum of the smallest and the middle numbers is:
2x + 1 + 2x + 3
3 times the largest number is:
3(2x + 5)
the sum of the smallest number and middle number is 27 less than 3 times the largest number, so:
2x + 1 + 2x + 3 = 3(2x + 5) - 27
4x + 4 = 6x + 15 - 27
-6x -6x
-2x + 4 = -12
-4 -4
-2x = -16
÷(-2) ÷(-2)
x = 8
2x+1 = 2•8+1 = 17
2x+3 = 2•8+3 = 19
2x+5 = 2•8+5 = 21
Check:
2x+1+2x+3 = 16+1+16+3 = 36
36+27 = 63
63:3 = 21 = 2x+5
