The answer is x= -17
hope this helps
Henrys design would result in a larger flower bed because its area would be 2500 square feet
The answers are n = 49, x = 59 and y = 9.
<u>Step-by-step explanation</u>:
Keep the unknown terms on one side and constant terms on other side to solve the given expressions.
1) Solve 67=n +18
n = 18 - 67
n = 49
2) Solve x-16=43
x = 43 + 16
x = 59
3) Solve 54=6y
6y = 54
y = 54/6
y = 9
(3,3) is where the lines intersect. a is the answer
Answer:
a) All dogs have fleas.
X the set of all animals
D(y)=y is a dog
F(y)=y has fleas
∀X ( D(x) → F(x) )
¬∃X ( D(x) ^ F(x) )
b) There exists a horse that can add.
X the set of all animals
H(y)=y is a horse
A(y)=y can add
∃X ( H(x) ^ A(x) )
∀X ( H(x) → ¬A(x) )
c) Every koala can climb.
X the set of all animals
K(y)=y is a koala
C(y)=y can climb
∀X ( K(x) → C(x) )
¬∃X ( K(x) ^ C(x) )
d) No monkey can speak French.
X the set of all animals
M(y)=y is a Monkey
F(y)=y can speak French
∀X ( M(x) → ¬F(x) )
∃X ( M(x) ^ F(x) )
e) There exists a pig that can swim and catch fish.
X the set of all animals
P(y)=y is a pig
S(y)=y can swim
C(y)=y can catch fish
∃X ( P(x) ^ ( S(x) ^ C(x) )
∀X ( P(x) → ( ¬S(x) v ¬C(x) ) )
