When subtracting fractions with the same denominator, you only have to subtract the numerators. Therefore, 7/16 - 3/16 = 4/16, which can be simplified to 1/4 if you divide the numerator and denominator by 4.
I believe its A, if you’re unsure just google how to prove a conjecture to be true
Answer:
61
Step-by-step explanation:
let the number be x then twice the number is 2x, hence
42 + 2x = 164 ( subtract 42 from both sides of the equation )
2x = 122 ( divide both sides by 2 )
x = 61
Hence the number is 61

Answer:
(- 2, 4 )
Step-by-step explanation:
y = 2x + 8 → (1)
y = - 2x → (2)
substitute y = 2x + 8 into (2)
2x + 8 = - 2x ( add 2x to both sides )
4x + 8 = 0 ( subtract 8 from both sides )
4x = - 8 ( divide both sides by 4 )
x = - 2
substitute x = - 2 into (2)
y = - 2(- 2) = 4
solution is (- 2, 4 )
