<span>Alex is 1.6 m tall
and
Noah is 1.5 times as tall as Alex
= 1.6 m x 1.5 = 2.4m
1 m = 100 cm
2.4 m = 2.4 x 100 = 240 cm
answer
Noah is 240 cm</span>
Answer:0.4074
Step-by-step explanation:I used google
Answer: x = 1, y = -2
Step-by-step explanation:
-9x+2y=-13
x= 13/9 + 2/9y
2x-9y=20
2(13/9+2/9y)-9y=20
<em>Substitute y with -2.</em>
<em />
x= 13/9+2/9(-2)
<em>After solving you'll see that 1 is a possible solution for x.</em>
<em />
Check your answer
-9x+2y=-13
-9x1+2(-2) = -13
2x-9y=20
2x1-9(-2) = 20
-13 = -13
20 = 20
Therefore, x=1 and y=-2
Since PQ is tangent to the circle, angle PQO is 90°.
Since the sum of angles of any triangle must be 180° we can say:
180-90-12=x thus:
x=78°
