2^x * 2 = 15
2^x= 15/2
2^x = 7,5
x = log 2 (7,5)
The phrase gives you an interval where the extremes are included.
The intervals may be indicated in several ways.
7.2 ≤ x ≤ 7.6
Answer:
17,18
Step-by-step explanation:
let the smaller integer be "a" and the larger be "b"
Then 2b = 3a -15 ........................equ 1
but they are consecutive integers, b= a+1 ; substitute b into equ 1,thus,
2(a+1) = 3a - 15
2a + 2 = 3a-15
collect like terms,
2+15 =3a-2a
17 = a
b= a+1
b = 17+1
b=18.
The integers are 17,18
