Add 0.2x to both sides
1.2x+0.7= 1
1.2x=.3
x=.3/1.2
x=.25
option #2
subtract .7 on both sides
x=1-.7-.2x
x=.3-.2x
1.2x=.3
x=.25
Your answer would 72.6 inches. The way you solved the answer is by adding all the numbers up, then dividing by how many ever numbers you have. Then, you’ll have your answer.
Answer: h = 9
Step-by-step explanation: A system of linear equations is consistent when it has at least one solution.
The matrix given is:
Transform this matrix in a row-echelon form:
For this row-echelon form to have solutions:
-9 + h = 0
h = 9
For this system to be consistent: h = 9.
Answer:
x = pi/2..only
Step-by-step explanation:
The equation states that...,
tan^2x.sin x = tan^2x
;we simplify the equation by dividing both sides by tan^2x...which then leaves our equation as,
; sin x = 1
; x = sin^-1 (1)
; Hence x = pi/2
