48 = -18x is an equivalent expression because you just subtact -18 from both sides.
Step-by-step explanation:
13x - 33 = 10x -------------- Corresponding angles
13x - 10x = 33
3x = 33
x = 33/3 = 11
angle 10x = 10(11) = 10 × 11 = 110
5y = 180 - 10x
5y = 180 - 10(11)
5y = 180 - 110
5y = 70
y = 70/5 = 14
Answer:
21/55
Step-by-step explanation:
Since there are already 2 girls on the relay team, what is left is to select 2 individuals be it a girl or a boy from the remaining 7 boys and 4 boys.
This can be done in 11C2 ways, and this equal 55 ways.
Now, we were told that we want exactly 2 boys on the team to join the other 2 girls already on the team. This mean we select 2 boys from the 7 boys. This can be done in 7C2 ways and this equals 21 ways.
Our probability is now 21/55
