Answer:
We need to find a relationship between the equations.
Let's solve for one variable.
2x + 2y = 15
2y = 15 - 2x
We know what 2y is in relation to x. Now we can solve.
2x + 15-2x = 15
15 = 15
Unless there are more equations, this is your answer. For it to be simultaneous you need more than one equation.
see how it do it in the picture and hope it helps you..
Answer:
u = -132
Step-by-step explanation:
33=-u/4
33*4=-u
132=-u
132/-1=u
-132=u
u = -132
Check:
33= -1(-132)/4
33=132/4
33=33
Hope this helps. Have a nice day.
Answer:
P(blue then red)=5/169
Step-by-step explanation:
the probability of picking the blue is 4/26 it's replaced so the total jellybeans doesn't change therefore the sample space doesn't change. the probability of picking a red is 5/26
to find the probability of picking them in that order, you multiply the two together
(4/26)x(5/26)=20/676
reducing that we get:
P(blue then red)=5/169
