Answer:

x=-3,y=-2

Step-by-step explanation:

Given 2 expressions

S1: $3x-8y=7$

S2: $x+2y=-7$

Write one equation in terms of any variable (x or y)

Here I am writing S1 in terms of y

$3x-8y=7\\3x-7=8y\\y=\frac{3x-7}{8}$

Substitute this value of y as the value of y in S2

⇒ $x+2y=-7\\x+(\frac{3x-7}{8} )\times2=-7\\8x+6x-14=-56\\14x=-42\\x=-3$

Therefore $x=-3$

Substitute this value of x in any of the expressions S1 or S2

Here i am substituting in S2

⇒ $x+2y=-7\\-3+2y=-7\\2y=(-7+3)\\2y=-4\\y=-2$

Therefore x=-3 and y=-2

Answer:

0.4 or $\frac{2}{5}$

Step-by-step explanation:

James spun the arrow 30 times which means 30 is the total. In other words, it's your denominator ( $\frac{x}{30}$ ). It landed on the blue section 12 times which means 12 is the part of the whole. In other words, it's your numerator ( $\frac{12}{y}$ ). Plug in the entire fraction and you get $\frac{12}{30}$ . Divide 12 by 30 and you get 0.4 or if you divide both the numerator & denominator by 6, you get $\frac{2}{5}$ . Either one works, depending on what your question asks for.
