Answer:

zero

Step-by-step explanation:

If the same sum is received for the sale of 20 apples at price p as is received for the sale of 140 apples at price p, then we must have ...

20p = 140p

120p = 0 . . . . . . subtract 20p

p = 0 . . . . . . . . . divide by 120

The price was zero.

Answer:

Price was 1 unit of money per each 7 apples and 3 units of money per each extra apple
Each woman received 20 unit of money

Step-by-step explanation:

This is the tricky one

I think 'The Seven Apple' is the hint. Let's see what the numbers have to do with 7:

20 = 7*2 + 6
40 = 7*5 + 5
60 = 7*8 + 4
80 = 7*11 + 3
100 = 7*14 + 2
120 = 7*17 + 1
140 = 7*20 + 0

Assume each '7 apples' sold for a fixed price x and each 'extra' apple sold for a different price y. Since all add up to make same amount, we get:

2x + 6y = 5x + 5y = ... = 20x

Let x = 1, then we get y = 3

<u>So we get the sold price:</u>

20 apples cost: 2*1 + 6*3 = 20
40 apples cost: 5*1 + 5*3 = 20
...
140 apples cost: 20*1 = 20

So each apple woman got 20 units of money for their apples.

Price was 1 unit of money per each 7 and 3 units of money per each extra apple

1. If the same number is added to the numerator and subtracted from the denominator of 23/12, the resulting fraction is equivale

ICE Princess25 [194]

Answer:

The number is -2

Step-by-step explanation:

step 1

Find the reciprocal of 2/3

Remember that when multiply a number by its reciprocal, the result is 1

The reciprocal of 2/3 is 3/2

step 2

Let

x-----> the number added to the numerator and denominator

$\frac{23+x}{12-x}=\frac{3}{2}$

Solve for x

$2(23+x)=3(12-x)\\46+2x=36-3x\\2x+3x=36-46\\5x=-10\\x=-2$

step 3

verify

$\frac{23+x}{12-x}$

substitute x=-2

$\frac{23-2}{12+2}$

$\frac{21}{14}$

Simplify

$\frac{3}{2}$ ----> is ok

therefore

The number is -2

What is the value of t?

solmaris [256]

Answer:

A) t = -3

Step-by-step explanation:

We have the expression $\frac{(t-12)}{2}=\frac{3t}{2}-3$ and we have to find the value of t.

First we are going to reorder the expression:

$\frac{(t-12)}{2}=\frac{3t}{2}-3\\\\3=\frac{3t}{2}-\frac{(t-12)}{2}\\\\3=\frac{3t-t-(-12)}{2}\\\\3=\frac{2t+12}{2}$

Now we have to multiply each side by 2,

$3=\frac{2t+12}{2}\\\\3.2=\frac{2t+12}{2}.2\\\\6=2t+12$

Subtract (-12) in both sides,

$6=2t+12\\6-12=2t+12-12\\-6=2t$

Divide both sides in 2,

$-6=2t\\\frac{-6}{2} =\frac{2t}{2} \\-3=t$

The answer is option A) t = -3.

Area of the plot = 193 sq.yd. , Option B is the correct answer.

Area is the space occupied by a flat surface or an object .

It is measured in square units

It has wide daily life importance like in the question mentioned , a plot will be measured in area of the space.

It is given that

A developer buys an empty lot to build a small house.

area of the lot = ?

The figure is incomplete and the complete figure is attached with the answer.

To determine the area the figure needs to be divided into triangles and rectangles as shown in the figure

Area of the first triangle = (1/2) * base * height

By Calculation

base = 17 unit and height = 10 unit

= (1/2) * 17 * 10

= 17*5

=85 sq.unit

Area of the second triangle = (1/2)* 9* 8

=36 sq. unit

Area of the rectangle = base * height

base = 9 unit and height = 7 unit

Area = 9*7= 63 sq.unit

Area of the last triangle = (1/2) * 2*9

= 9 unit

The area of the plot = 85+36+63+9

Area of the plot = 193 sq.yd.

Therefore , Option B is the correct answer.
