Please answer me this question ​
Jobisdone [24]

Answer:

x = 2

y = 3

Step-by-step explanation:

\left \{ {{0.4x + 0.3y = 1.7} \atop {0.7x - 0.2y = 0.8}} \right.

\left \{ {{2(0.4x + 0.3y) = 2 * 1.7} \atop {3(0.7x - 0.2y) = 3 * 0.8}} \right.

\left \{ {{0.8x + 0.6y = 3.4} \atop {2.1x - 0.6y) = 2.4}} \right.

2.9x = 5.8

29x = 58

x = 2

0.3y + 0.4x = 1.7

0.3y + 0.4 * 2 = 1.7

0.3y + 0.8 = 1.7

0.3y = 0.9

3y = 9

y = 3

Determine the value for AB
grin007 [14]

Answer:

x = 2

AB = 14

Step-by-step explanation:

2x(10) = 8(x+3)

20x = 8x + 24

subtract 8x from both sides

12x = 24

x = 2

Check:

4(10) = 8(5)

40 = 40

Correct

2x = 2 x 2 = 4

4 + 10 = 14

If my answer is incorrect, pls correct me!

If you like my answer and explanation, mark me as brainliest!
