Answer:
one solution (-2 ; 5)
Step-by-step explanation:
hello : 2x + 3y= 11
...(*)
-x-5y=-23.....(**)
by(**) : x= -5y+23
put this value into (*) : 2(-5y+23)+3y=11
-10y+46+3y=11
-7y = -35
y=5
but x= -5y+23
so : x= -5(5)+23 =-2
Answer:
Step-by-step explanation:
5^2+8^2=c^2
25+64=89
89=c^2
square root of 89 is 9.43
9.43=the square root of c^2
Answer:
5/11
explanation
Probability here is the chance of selection out of a total. So, we need to first find the total number of marbles.
total
=
5
+
3
+
2
+
1
=
11
So there are
11
marbles total. The probability that we pick one of the
3
green marbles out of the
11
is simply that ratio:
P
green
=
3
11
Same idea for yellow:
P
yellow
=
2
11
The probability of picking either of these colors is simply the sum of their probabilities.
P
green or yellow
=
P
green
+
P
yellow
=
3
11
+
2
11
=
5
11
5y and 155 create a straight line so:
5y + 155 = 180
5y = 25
y = 5
5y and 13x create a 90 angle so:
5y = 5(5) = 25
25 + 13x = 90
13x = 65
x = 5
Hope this helps :)
