3 0

Answer:

2x + y = 4

4x + 2y = 12

Step-by-step explanation:

Equations 2x + y = 4 & 4x + 2y = 12 haven't the same solution.

2x + y = 4...(1) \\ 4x + 2y = 12 \\ 2(2x + y) = 12 \\ 2x + y =  \frac{12}{2}  \\ 2x + y = 6...(2) \\ rhs \: of \: equations \: (1) \: and \: (2) \: are \:  \\ not \: sme.

1) Multiply the length value by 100,000.

2.5 \: hm = 2.5 \times 100000

=  >2.5 \: hm = 250000 \: mm

2) For this, divide the length value by 1000.

=  >  \frac{1800}{1000}

=  > 1.8 \: dam

3) For finding the approximate value, just multiply the value of length by 1.609.

=  >6450 \: m = (6450 \times 1.609) \: km

=  > 10380.27 \: km

4) Multiply the given mass value by 100.

=  > 1.2 \: kg = 1.2 \times 100

=  > 1200 \: g

5) Multiply the given value by 10,000.

4.37 \: dag = 4.37 \times 10000

=  > 43700 \: mg

x = 17

7) if you draw a line from T passing through the centre of the circle, it will divide the triangle into two congruent triangles
