Answer:
x = 13
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
= 
, substitute values
= 
( cross- multiply )
78(11x - 13) = 10140 ( divide both sides by 78 )
11x - 13 = 130 ( add 13 to both sides )
11x = 143 ( divide both sides by 11 )
x = 13

Answer: x>7
Step-by-step explanation:
Because 2 tons of ore in an hour
It says that the government purchase 4 tons, and 10 tons are sold to the mineral extractor
4+10=14
14÷2=7
14>7
Answer:
For the given linear equation in two variables, the solution to the system of equations is (-2, -6).
Given :
y = x - 4 ---- (1)
y = 4x + 2----- (2)
Linear equations are nothing but yet another subset of "equations". Any linear calculations requiring more than one variable can be done with the help of linear equations.
The standard form of a linear equation in two variables is of the form. Here, x and y are variables, and a, b and c are constants.
From equations (1) and (2) we get,
x-4 = 4x + 2
x = - 2
Now, from equation (1) we get,
y = -2 -4
y = - 6
The solution to the system of equations is (-2, -6).
