Divide 276 by 3 to get 92.  Then add 92 and 92 to get 184 which is 2/3 of 276. Then subtract 20 to get 164. He read 164 pages last week. I am pretty sure this is right. 
Hope this helps!!!

On a coordinate plane, a line is drawn from point a to point b. point a is at (7, negative 2) and point b is at (negative 8, neg
dimaraw [331]

The coordinate of the partition c on the line segment is (1.2, -4.7)

<h3>How to determine the coordinates of the partition?</h3>

The coordinates are given as:

A = (7,-2)

B = (-8,-9)

m:n = 5:8

The coordinate of the partition is calculated using:

(x,y) = \frac{1}{m + n} * (mx_2 + nx_1, my_2 + ny_1)

So, we have:

(x,y) = \frac{1}{5 + 8} * (5 * -8 + 8 * 7, 5 * -9 + 8 * -2)

Evaluate the sum and products

(x,y) = \frac{1}{13} * (16, -61)

Evaluate the product

(x,y) = (1.2, -4.7)

Hence, the coordinate of the partition on the line segment is (1.2, -4.7)

A car owner buys diesel at rs 7.50, rs 8, rs 8.50 per litre for three successive years. what approximately is the average cost p
alex41 [277]

Answer:

Average cost per litre of diesel = rs 8.00

Step-by-step explanation:

Amount spent on diesel each year = rs 4000

Price of a litre of diesel in the first year = rs 7.50

Price of a litre of diesel in the second year = rs 8.00

Price of a litre of diesel in the third year = rs 8.50

Average cost per litre of diesel = \frac{p_{1} + p_{2} + p_{3}  }{n}

where n is the number of years.

Average cost per litre of diesel  =  \frac{7.5 + 8.00 + 8.50}{3}

                                                     = \frac{24}{3}

                                                     = 8

Average cost per litre of diesel is rs 8.00

So that he buys an average of 500 (i.e \frac{4000}{8}) litres every year.
