Convert the decimal number to a fraction by placing the decimal number over a power of ten. Since there are
3 numbers to the right of the decimal point, place the decimal number over
10^3 (1000). Next, add the whole number to the left of the decimal.

1 875/1000

Reduce the fractional part of the mixed number.

52 ( Blank ) 2 ( Blank ) 31 = 73
nadezda [96]

Answer:

52 × 2 - 31 = 73

Step-by-step explanation:

Use PEMDAS

The way I remember is like this..

Please (Parentheses)

Excuse (Exponents)

My (Multiication)

Dear (Division)

Aunt (Addition)

Sally (Subtraction)

Multiply 52 × 2

which gives you 104.

Then subtract 31 from 101

and that will give you 73.

Answer:

The coordinates of E are E(x,y) = \left(\frac{9}{2}, 0 \right).

Step-by-step explanation:

The triangle ABC represents a right triangle as both sides AB and AC are orthogonal to each other. The side AB is in the y axis, whereas the side AC is in the x axis. The triangle is dilated with respect to the origin, in which point A is set.

Vectorially speaking, dilation is defined by the following operation:

P'(x,y) = O(x,y) + k\cdot [P(x,y) - O(x,y)] (1)

Where:

O(x,y) - Point of reference.

P(x,y) - Original point.

P'(x,y) - Dilated point.

k - Dilation factor.

By applying this operation, point B becomes point D:

B(x,y) = (0,4), D(x,y) = (0,6)

D(x,y) = (0,0) + k\cdot [(0,4)- (0,0)]

D(x,y) = (0,0) + k\cdot (0,4)

(0,6) = (0,0) +(0,4\cdot k)

(0, 6) = (0,4\cdot k)

k = \frac{3}{2}

Lastly, we transform point C into point E by applying the same operation: C(x,y) = (3, 0), O(x,y) = (0,0) and k = \frac{3}{2}

E(x,y) = (0,0) + \frac{3}{2}\cdot [(3,0)-(0,0)]

E(x,y) = \left(\frac{9}{2}, 0 \right)

The coordinates of E are E(x,y) = \left(\frac{9}{2}, 0 \right).
