X=15
Just divide 5x by 5 and 75 by 5
5x - 3y = 15
5x - <u>5x</u> -3y = <u>- 5x</u> + 15
<u>-3y</u> = <u>-5x</u> + 15
3y = 5x - 15
divide all of them by 3...
y = 5/3 - 5
Answer:
x = 23
Step-by-step explanation:
the sum of the 3 angles in a triangle = 180°
the third angle forms a straight angle with 100°, hence
third angle in triangle = 180° - 100° = 80°
Summing the 3 angles gives
2x + 3 + 80 + 51 = 180
2x + 134 = 180 ( subtract 134 from both sides )
2x = 46 ( divide both sides by 2 )
x = 23
Answer:
To write 0.111 as a fraction you have to write 0.111 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.
0.111 = 0.111/1 = 1.11/10 = 11.1/100 = 111/1000
And finally we have:
0.111 as a fraction equals 111/1000
-3/4 = -0.75
-0.75 • 24 = -18
-18/24
