Answer:
237 students graduated
Step-by-step explanation:
Subtract 172 from 409, obtaining 237.
237 students graduated
-4x + 3y = 6
-4x + 4x + 3y = 6 + 4x
<u>3y</u> =<u> 6 + 4x</u>
3 3
y = 2 + 4/3x
-4x + 3(2 + 4/3x) = 6
-4x + 6 + 4x = 6
-4x + 4x + 6 = 6
0x + 6 = 6
<u> -6 -6</u>
<u>0x</u> = <u>0</u>
0 0
x = 0
-4(0) + 3y = 6
0 + 3y = 6
<u>+0 +0</u>
<u>3y</u> = <u>6</u>
3 3
y = 2
(x, y) = (0, 2)
Answer:
Step-by-step explanation:
follow PEMDAS (parentheses, exponent, multiplication, division, addition, subtraction)
Complementary angles add up to 90°
Let one of the angle be x.
The other angle is 29x.
x + 29x = 90
30x = 90
x = 3
29x = 29(3) = 87
Answer: The two angles are 3° and 87°
