-5y+ 6y = -12
Ax + by = c
It's just rare to leave "ax" as negative, so we multiply everything by "-1" in order to change that;
but that is already in standard form, because it is in the ax+by= c, form.
5y - 6y = 12
Answer:
A. 1/2.
B. 15/26.
Step-by-step explanation:
Note when you have an 'OR' in the statement we <u>add </u>the probabilities.
A . Club or a diamond . There are 13 clubs and 13 diamonds so
The Required Probability = 13/52 + 13/52
= 1/4 + 1/4 = 1/2.
B. There are 4 jacks and 26 black cards.
The Required Probability = 4/52 + 26/52
= 1/13 + 1/2
= 2/26 + 13/26
= 15/26.
Step-by-step explanation:
we can find the area of parallelogram by multiplying base and height i.e A = bh
