Answer:

The value of  \frac{4b}{a}   is   240

Step-by-step explanation:

We were given the equation: a x 60 = b

To find the value of 4b/a, we are going to follow the following step;

First, divide both-side of the equation by a, thus our equation becomes:

 a x 60/a   =  b/a

On the left-hand side of the equation, 'a' at the numerator will cancel-out 'a' at the denominator. Our equation becomes;

60 = b/a

Then, the next step is to multiply 4 to both-side of the equation, our equation becomes

4 x 60 = 4 x b/a

240 = \frac{4b}{a}

\frac{4b}{a}  =240

Therefore, the value of  \frac{4b}{a} is 240

Answer:

240

Step-by-step explanation:

Given

60a = b ( divide both sides by a )

60 = \frac{b}{a} ( multiply both sides by 4 )

240 = \frac{4b}{a}

Find all x ∈ Z satisfying each of the following equations.3x = 2 (mod 7)
Vlada [557]

Answer:

7x−3=7k,x=7k+3,k∈ℤ

Step-by-step explanation:

3x ≡ 2 (mod 7)

3 is a solution, since 3×3−2=7.

All solutions are 3+7ℤ

y=3x−2/7=3(x−3)+7/7=3(x−3)/7+1

7x−3=7k,x=7k+3,k∈ℤ

ACME insurance company estimates that the probability of the owners’ of a house worth between $120,000 to $170,000 making a clai
olchik [2.2K]

The expected value of this policy to the insurance company is $285.00.

Using this formula

Policy expected value=Insurance policy charges-[(Probability × Claim)+(Probability × Claim)]

Let plug in the formula

Policy expected value=$1,300-{(.0041)($150,000)+(.08)($5,000)]

Policy expected value=$1,300-($615+$$400)

Policy expected value=$1,300-$1,015

Policy expected value=$285.00

Inconclusion the expected value of this policy to the insurance company is $285.00

Determine whether the congruence is true or false.<br> 12 ≡ 10 mod 5
dolphi86 [110]

Answer:

The given congruence is false.

Step-by-step explanation:

Given : Expression 12 \equiv 10 \mod 5

To find : Determine whether the congruence is true or false ?

Solution :

The congruence is in the form x\mod y\equiv r

where, x is the dividend

y is divisor

r is the remainder

So, We find  10 \mod 5

We know, 10 is completely divide by 5 and we get quotient is 2 and remainder is 0.

10 \mod 5=0

As 0\neq 12

Therefore, The given congruence is false.
