Answer:
C
Step-by-step explanation:
Step-by-step explanation:
well first of all you have to expand the brackets. so 5(y+2)=4(x-3)
5y+10=4x-12
then you subtract 10
5y=4x-12-10=4x-22
then divide by 5 to get the value of y
y=(4x-22)/5
Answer:
A. 2 1/4 + 3 2/5
B. 113/20
Step-by-step explanation: For A: All you had to do was multiply -1(-3 2/5) and that was going to make your answer positive because the negatives were going to cancel each other out.
For B: First you had to make your fractions improper fractions instead of mixed numbers. And that would make it 9/4 + 17/5. Next, since they don't have the same denominator, you would have had to find the least common multiple of 5 and 4 which is 20. So then how ever many times your denominator went in to 20, that's what you'll multiply your numerator by. 45/20 + 68/20= 113/20
Answer:
The probabily of P(not less than 6) is
P= the favorable outcomes/ the total outcomes
favorable out come is 1 case(7)
the total outcomes are 5 cases(2,3,5,6)
P=1/5=20%
