-3(4r - 8) = -36
Mutiply the bracket by -3
(-3)(4r)(-3)(-8)= -12r+24
-12r+24= -36
move +24 to the other side
sign changes from +24 to -24
-12r+24-24= -36-24
-12r= -60
divide by -12
-12r/-12= -60/-12
r= 5
Answer: r= 5
Answer:
Z(integer)
Step-by-step explanation:
N is subset of W
W is subset of Z
Z is subset of Q
Q and Q* are subset of R
Well, is not a product, just a sum of three terms, so to simplify simply expand and combine them as constants,
3² + 3⁴ + 3⁷
9 + 81 + 2187
2277
48.98 -36.27 can be found without regrouping
Answer:
3/20 or 15%
Step-by-step explanation:
Out of 1,2,3,4, and 5, there are 3 prime numbers. This makes the odds of selecting one of those prime numbers 3/5. Then, saying that he does pick a prime number and discards that card, there are now four cards, one of them being the number one. His chances of selecting this card is 1/4.
To find the probability you need to multiply the two probabilities together.
3/5 times 1/4 is 3/20.
So your answer is 3/20 or 15%.
