Answer:
so we have 4(3x + 10)
then we are going to take the 4 and distribute it into our problem
so: 4(times)3x and then 4( times)10
to get :
<h2>12x+40</h2>
Step-by-step explanation:
I think the answer is that what i think
461 because you take 506-45 to find x(the unknown number)
Answer:
x = 15°
y = 59°
Step-by-step explanation:
Angles at a right angle add up to 90°
41 + y = 90
y = 90 - 41
y = 59°
Angles in a triangle add up to 180°
41 + (2x - 9) + 7x + 13 = 180
41 + 13 - 9 + 2x + 7x = 180
45 + 9x = 180
9x = 180 - 45
9x = 135
x = 135/9
x = 15°
20 seconds
i feel like that is right
