Construct a truth that shows (~Pv~Q)→(P^~Q)

P : {T, T, F, F}

Q : {T, F, T, F}

~P : {F, F, T, T}

~Q : {F, T, F, T}

~P ∨ ~Q : {F, T, T, T}

P ∧ ~Q : {F, T, F, F}

(~P ∨ ~Q) => (P ∧ ~Q) : {T, T, F, F}

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
