Answer:

x = 33

Step-by-step explanation:

x - 12 and 2x + 3 form a right angle , then

x - 12 + 2x + 3 = 90

3x - 9 = 90 ( add 9 to both sides )

3x = 99 ( divide both sides by 3 )

x = 33

77julia77 [94]
Since posters cost 9 dollars each and picture frames cost 15, it would be multiplication.

The expression would be 9(6)+15(6) or 9x6+15x6.

You have to multiply these numbers. 9 times 6 would be 54. 15 times 6 would be 90.

Now, we need to add these together. 54 plus 90 would be 144.

The total cost for 6 framed posters would be $144.

choli [55]
According to the 55 m/min speed, in 3 minutes, he should have traveled 165 m.
Since he only went 135 m, that means the water moved against him for 30 m. That also happened in 3 min so the water is moving against him at 10m/min.
