Answer/Step-by-step explanation:

The following shows the reasons for each step taken in proving that x = \frac{61}{9}:

Step 1:

9(x - 2) + 32 = 75 => R1: Given

Step 2: apply the subtraction property of equality by subtracting 32 from each side of the equation.

9(x - 2) + 32 - 32 = 75 -32

9(x - 2) = 43 => R2: Subtraction property of equality

Step 3: Eliminate the parentheses by applying the distributive property of multiplication

9x - 18 = 43 => R3: distributive property of multiplication

Step 4: Apply the addition property of equality by adding 18 to each side.

9x - 18 + 18 = 43 + 18

9x = 61 => R4: Addition property of equality

Step 5: Apply the division property if equality by dividing both sides by 9.

\frac{9x}{9} = \frac{61}{9}

x = \frac{61}{9} => R5: Division property of equality

Claire is painting some doors that are all the same size. She used 2 liters of paint to cobe 1 3/5 doors. How many liters of pai
Deffense [45]

Answer:

1 \dfrac{1}{4} \ liters

Step-by-step explanation:

Given that:

Claire uses 2 liters of paint to cover 1 3/5 doors

Then in order for her to paint 1 door, She will need:

2 L = 1 3/5 door

x L = 1 door

x (L) = \dfrac{2 L \times 1 door }{ 1 \dfrac{3}{5}   \ door}

x (L) = \dfrac{2 L  }{ 1 \dfrac{3}{5}  }

x (L) = \dfrac{2 L  }{  \dfrac{8}{5}  }

x (L) = \dfrac{2 L\times 5  }{  8  }

x (L) = \dfrac{10 \ L }{  8  }

x(L) =1 \dfrac{1}{4} \  L

44. Express each of these system specifications using predicates, quantifiers, and logical connectives. a) Every user has access
DENIUS [597]

Answer:

a. ∀x (User(x) → (∃y (Mailbox(y) ∧ Access(x, y))))

b. FileSystemLocked → ∀x Access(x, SystemMailbox)

c. ∀x ∀y ((Firewall(x) ∧ Diagnostic(x)) → (ProxyServer(y) → Diagnostic(y))

d. ∀x (ThroughputNormal ∧(ProxyServer(x)∧ ¬Diagnostic(x))) → (∃y Router(y)∧Functioning(y))

Step-by-step explanation:

a)  

Let the domain be users and mailboxes. Let User(x) be “x is a user”, let Mailbox(y) be “y is a mailbox”, and let Access(x, y) be “x has access to y”.  

∀x (User(x) → (∃y (Mailbox(y) ∧ Access(x, y))))  

(b)

Let the domain be people in the group. Let Access(x, y) be “x has access to y”. Let FileSystemLocked be the proposition “the file system is locked.” Let System Mailbox be the constant that is the system mailbox.  

FileSystemLocked → ∀x Access(x, SystemMailbox)  

(c)  

Let the domain be all applications. Let Firewall(x) be “x is the firewall”, and let ProxyServer(x) be “x is the proxy server.” Let Diagnostic(x) be “x is in a diagnostic state”.  

∀x ∀y ((Firewall(x) ∧ Diagnostic(x)) → (ProxyServer(y) → Diagnostic(y))  

(d)

Let the domain be all applications and routers. Let Router(x) be “x is a router”, and let ProxyServer(x) be “x is the proxy server.” Let Diagnostic(x) be “x is in a diagnostic state”. Let ThroughputNormal be “the throughput is between 100kbps and 500 kbps”. Let Functioning(y) be “y is functioning normally”.  

∀x (ThroughputNormal ∧(ProxyServer(x)∧ ¬Diagnostic(x))) → (∃y Router(y)∧Functioning(y))

At the market 8 apples cost $4 how much do 9 apples cost ?
castortr0y [4]
If 8 apples cost $ 4, then (4/8) = 1/2 (or 0.50)....so each apple is 0.50 (or 50 cents)

so if u want 9 apples, u will have to pay : 9 * 0.50 = $ 4.50 <=
