90 - x = 4x
4x + x = 90
5x = 90
x = 90/5
x = 18
<span> √3 - i = 2e^(5πi/6)
(2e^(5πi/6))^-10 = 2^-10 * e^(-25πi/3)
= 2^-10 * (cos(-25π/3) + isin(-25π/3))
= 2^-10* (1/2 - i(√3/2)) </span>
Answer:
If the first number is x and y is the second number
x = 11
y = 18
Step-by-step explanation:
If x is the first number and y is the second number then:
x + 7 = y
The sum of the two numbers is expressed as:
x + y = 29
In order to find what the two numbers are, use what you know. According to the first equation, y equals the first number(x) plus 7, so you can substitute that for the y in the second equation
x + y = 29
x + (x + 7) = 29
2x + 7 = 29
2x + 7 - 7 = 29 - 7
2x/2 = 22/2
That means x equals 11
Now that x is known, you can find the value for y. The second number(y) is 7 more than than the first number(x) so that means x + 7 = y
11 + 7 = y
y = 18
