Answer:

C

Step-by-step explanation:

The 10 inch sides will produce 10 / 3 = 3 squares and 1 inch left over.

The 18 inch sides will produce 18/3 = 6 squares with nothing left over.

The number of squares is 3 * 6 = 18

The endpoints of a line segment are (4,6) and (-6,2). Point G divides the segment into two equal parts. What are the coordinates
-BARSIC- [3]

Answer:

(-1, 4)

Step-by-step explanation:

Given the endpoints of line segments to be (4,6) and (-6,2).

Coordinate of point G is expressed as its midpoint;

M(X, Y) = {x1+x2/2, y1+y2/2}

X = 4-6/2

X = -2/2

X = -1

Y = 6+2/2

Y = 8/2

Y = 4

Hence the coordinate of point G is (-1, 4)

Solve for x:<br>(a) 4x - 21 = 5 - 9x​
lisabon 2012 [21]

Answer:

X = 2

Step-by-step explanation:

First we'll need to simplify this equation:

Add 9x on both sides:

13x - 21 = 5

Add 21 on both sides:

13x = 26

Divide 26/13

26/13 = 2

X=2

(You can check this yourself by plugging x into the equation)

A garden store bought a fountain at a cost of $995.66 and marked it up 100%. Later on, the store marked it down 25%. What was th
irinina [24]

Answer:

  $1493.49

Step-by-step explanation:

  marked price = cost price + markup

  = cost price + 100% × cost price = 2×cost price

  marked price = 2($995.66) = $1991.32

The discount is 25% of this value, or ...

  discount = 25% × $1991.32 = $497.83

Then the discounted price is ...

  discounted price = marked price - discount

  = $1991.32 -497.83 = $1493.49

The discounted price was $1493.49.

_____

<em>Additional comment</em>

In terms of multiplying factors, the marked-up price is (1 +100%) = 2 times the original cost. The discounted price is (1 -25%) = 0.75 times the marked-up price. Then the discounted price is ...

  cost(2)(0.75) = 1.5·cost = 1.5·$995.66 = $1493.49
