Eunique scores 20 points during the game. This is eleven more than three-fifths of the points she scored in previous game. How m
Ket [755]

Answer:

Step-by-step explanation:

If we call the points she scored in the last game x, we can actually write out an equation to describe what is being said.  20=11+(3/5)x.  Hopefully that makes sense.  3/5 of the previous score plus 11 is 20.  Anyway, you can just solve this algebraic expression for x.

20=11+(3/5)x subtract 11 from both sides

9 = 3/5 x Multiply both sides by 5

45 = 3x then divide both sides by 3

15 = x And there you go.

Solve for a side triangles please help it’s urgent please answer
rodikova [14]

Answer:

AC ≈ 2.87

Step-by-step explanation:

Using the sine ratio in the right triangle

sin35° = \frac{opposite}{hypotenuse} = \frac{AC}{AB} = \frac{AC}{5}

Multiply both sides by 5

5 × sin35° = AC , thus

AC ≈ 2.87 ( to the nearest hundredth )
