Answer:
1
Step-by-step explanation:
12+[2-(4 × a²)] ÷ 7+b
= 12+[2-(4 × 5²)] ÷ 7+ 1
= 12+[2-(4 × 25)] ÷ 7+ 1
= 12 + (2 - 100)÷ 7 + 1
= 12 - 98 ÷ 7 + 1
= 12 - 14 + 1
= 1
Answer:
3/16
Step-by-step explanation:
since the question has "and" we will be multiplying two unrelated probabilities
P(gray on 1) = 1/4
P(blue on 2) = 3/4
the second probability is not affected since we are not taking away the first space after we land on it
1/4 * 3/4 = 3/16
Answer:
32
Step-by-step explanation:
15x+19=2(10x+2)
15x+19=20x+4
19-4=20x-15x
15=5x
x=3
PQ=QN
10x+2=
10(3)+2=
30+2=
