What is the x value in the soe?
x - 5y = 0
2x - 3y =7

I will solve your system by substitution.x−5y=0;2x−3y=7Solve x−5y=0 for x:x−5y+5y=0+5y (Add 5y to both sides)x=5ySubstitute 5y for x in 2x−3y=7:2x−3y=725y−3y=77y=7 (Simplify both sides of the equation)7y7=77 (Divide both sides by 7)y=1Step: Substitute 1 for y in x=5y:x=5yx=(5)(1)x=5(Simplify both sides of the equation)
Your 5 is the value of X and Y is the value of 1

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
