Answer: -49
Step-by-step explanation: I just kept subtracting by two and changing the first number because the last digit alternates between 1, 3, 5, 7, and 9.
Answer:
12
40
48
7
Step-by-step explanation:
To solve the equation use inverse operations. When multiplication is present, use division. When division is present, use the reciprocal and multiplication.
3/4 x= 9 x = 9 * 4/3 = 12
5/8 k= 25 x = 25 * 8/5 = 40
a/6 = 8 x = 8*6 = 48
7s = 49 s = 49/7 = 7
y = abˣ
20 = ab¹
20 = ab
b b
20/b = a
y = abˣ
4 = (20/b)b²
4 = 20b
20 20
¹/₅ = b
y = abˣ
20 = ¹/₅b¹
20 = ¹/₅b
¹/₅ ¹/₅
100 = b
y = abˣ
y = 100(0.2)ˣ
