Answer:
y+what ever the angle inside=180 since its on a line
180-128=52
52+z+x=180since thats always the angles of a triangle added up
52+91+x=180
add
143+x=180
-143
x=37
Hope This Helps!!!
Answer:
x = 1.27
y = 5.18
Step-by-step explanation:
to solve this system of equation by simultaneous equation we say that let
3x+y=9.............................. equation 1
-5x+2y=4 .......................... equation 2
from equation 1
3x+y=9.............................. equation 1
y = 9 -3x.............................. equation 3
substitute the value of y = 9 -3x into equation 2
-5x+2y=4 .......................... equation 2
-5x + 2( 9 -3x) = 4
-5x + 18 - 6x = 4
collect the like terms
18 - 4 = 6x + 5x
14 = 11x
divide both side by 11
14/11 = 11x/11
x = 14/11
x = 1.27
put the value of x = 1.27 into equation 3
y = 9 -3x.............................. equation 3
y = 9 - 3( 1.27)
y = 9 - 3.82
y = 5.18
<em>to check if you are correct put the value of x and y into either equation 1 or equation 2.</em>
<em>3x+y=9.............................. equation 1</em>
<em>3( 1.27) + 5.18 = 9</em>
<em>3.81 + 5.18 = 9</em>
<em>9 = 9</em>
Answer: 1/11 is the simplified form...
Hope this helps, stay safe :D
Step-by-step explanation:
if x is games won
then games lost is x+14
total no of games=40
x+x+14=40
2x=40-14
x=13 games won
$42,500 because 45900 dividede by 1.08 is 42500
