Yes, the above statement is True.
Answer:
x~11
Step-by-step explanation:
22:17=14:x
22/17=14/x
22x=17*14
22x=238
22x/22=238/22
x=238/22
x=10.818181818181818
x~11
Answer:
(5, -1)
Step-by-step explanation:
Equation 1: 3x + y = 14
Equation 2: 2x - 2y = 12
Rewrite equation 1 to make y the subject:
⇒ y = 14 - 3x
Substitute this into equation 2 and solve for x:
⇒ 2x - 2(14 - 3x) = 12
⇒ 2x - 28 + 6x = 12
⇒ 8x - 28 = 12
⇒ 8x = 40
⇒ x = 5
Substitute found value for x into either equation and solve for y:
using equation 1:
⇒ 3(5) + y = 14
⇒ 15 + y = 14
⇒ y = -1
Therefore, the solution to the system is (5, -1)
Answer:
x = 5.
Step-by-step explanation:
x^3 - x = 120
We first guess the value of x and calculate the left side.
Take x = 4:-
4^3 - 4 = 64-4 = 60
This is < 120 so try x = 5:
5^3 - 5 = 125 - 5 = 120.
So one solution is x = 5.
