Answer:

A= 429

B= 50

Explanation:

A+B= 479 (take away)

A-B= 379

A-A+B+B= 479-379 (simplify)

2B= 100

I think you know how to do it now..

B=50

A=50+379 ---> 429

This is the substitution method, there are other ways of doing it- and I tried to make this simple. Hope this helped!

Find the point that is 3/4 of the distance P (-6,-5) to the point Q (2,7)
Zarrin [17]

Using proportions, the coordinates of the point 3/4 of the way from P to Q are: (0,4).

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

We want to find the coordinates of point M(x,y) 3/4 of the way from P to Q, hence the rule is given by:

M - P = 3/4(Q - P)

For the x-coordinate, we have that:

x + 6 = 3/4(2 + 6)

x + 6 = 6

x  = 0.

For the y-coordinate, we have that:

y + 5 = 3/4(7 + 5)

y + 5 = 9.

y = 4.

The coordinates are (0,4).

SVEN [57.7K]

Cost of painting is GHe 109,320

<u>Given:</u>

Floor measure = 15 m by 8 m

Cost of carpeting = GHe 890 per square meter

Total cost of painting and carpeting = GHe 216,120

<u>Find:</u>

Cost of painting

<u>Computation:</u>

Area of floor = 15 × 8

Area of floor = 120 square meter

Cost of carpeting = 120 × 890

Cost of carpeting = GHe 106,800

Cost of painting = Total cost of painting and carpeting - Cost of carpeting

Cost of painting = 216,120 - 106,800

Cost of painting = GHe 109,320
