Answer:

Eight less than four times a number is equal to two times the difference of double that same number decreased by three.

Step-by-step explanation:

The given equation is:

4x−8=2(2x−3)

We will try to translate the given equation in English.

We can see that the variable used is only one. On the left hand side of the equation 8 is being subtracted from 4 times of the variable and on the right hand side 3 is being subtracted from 2 times of variable and then being multiplied by two.

From the given option, correct answer is:

Eight less than four times a number is equal to two times the difference of double that same number decreased by three.

Answer:

price of 50 kg rice rupees 7650 find the price of 1 kg rice

so 50kg: 7650r

divide both sides by 50 to get 1

1kg=153 rupees

Answer:

50kg of rice --> 7650 rupees

7650/50 = 153

1kg of rice --> 153 rupees

the answer is a i believe

Step-by-step explanation:

The solution is Option A.

The total time it took to travel from the house to Gurnee Mills is given by the equation A = 2 hours

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total time to travel from the house to Gurnee Mills be A

Now , the equation will be

The time it took to travel to Gurnee Mills without waiting = 1 hour

The waiting time before travel = 1 hour

So , the total time to travel from the house to Gurnee Mills A = time it took to travel to Gurnee Mills without waiting + waiting time before travel

Substituting the values in the equation , we get

The total time to travel from the house to Gurnee Mills A = 1 + 1

On simplifying the equation , we get

The total time to travel from the house to Gurnee Mills A = 2 hours

Therefore , the value of A is 2 hours

Hence , the the total time is 2 hours

< - 6, 9 > + < 5, - 3 >

If r= (2,3) s= (5,-3) t= (-8,6) then (7,0)+(-8,6) ,(2,3)+(-3,3) and (-6,9)+(5,-3) are equal to (r+s)+t

Vector is a quantity with magnitude and direction .

Given vectors in component form are

r=(2,3) ,s=(5-3) , t =(-8,6)

We can calculate (r+s) as

(2,3)+(5,-3)

=(2+5,3-3)

=(7,0)

Now we can calculate (r+s)+t as

(7,0)+(-8,6)

(7-8,0+6)

(-1,6)

(a)

(0,7)+(-8,6)

=(-8,1)

Not equal to (r+s)+t

(b)

(7,0)+(-8,6)

=(-1,6)

equal to (r+s)+t

(c)

(2,3)+(-3,3)

=(-1,6)

equal to (r+s)+t

(d)

(2,3)+(3,-3)

=(5,0)

Not equal to (r+s)+t

(e)

(-6,9)+(5,-3)

=(-1,6)

equal to (r+s)+t

If r= (2,3) s= (5,-3) t= (-8,6) then (7,0)+(-8,6) ,(2,3)+(-3,3) and (-6,9)+(5,-3) are equal to (r+s)+t

Answer:

B

Step-by-step explanation:

Answer: The given expression "2 divided by the quantity of 2 plus 5i" can be translated as 2/(2+5i). Simplifying expressions aim is to simplify it into its simplest form. Since i = √-1 substitute it into the expression.

2/(2+5√-1)

then multiply it by 2-5√-1 on the numerator and denominator and we have

[2(2 - 5√-1)] / [4 - 25(1)]

(4-10√-1)/(-21)

Step-by-step explanation:

Answer:

(x + 8)² = 36

Step-by-step explanation:

When you are trying to complete the square and the equation already has a constant, you add or subtract that value to the other side of the equation so you can cancel it out.

x² + 16x + 28 = 0

x² + 16x + 28 - 28 = 0 -28

x² + 16x = -28

Now, you find ([tex]\frac{b}{2}[/tex])² (divide b by 2 and raise the quotient to the second power). Half of 16 is 8, and 8² is 64. Add 64 to both sides.

x² + 16x + 64 = -28 + 64

x² + 16x + 64 = 36

Now, you just factor the equation on the left. To factor it, you will always use the number you got to make the constant, which in this case is 8.

(x + 8)² = 36

convert to exponential form

8^x=512=8^3

x=3

The logarithm of 512 to the base 8=3

Answer:

41

Step-by-step explanation:

4x +5 = 7x -22

5 = 3x -22

27 = 3x

x = 27/3

x = 9

4(9) + 5 = RS

36+ 5 = RS

RS = 41

Answer:

RS=41

Step-by-step explanation:

Because RT intersects the midpoint of QS, from doing some geometry we know that QRT and SRT are congruent triangles. Thus, RS=RQ because of cpctc

so, we can make the equation:

4x+5=7x-22

simplify

3x=27

x=9

now, plug that into 4x+5, and we get 36+5, or 41. RS=41

Answer:

Step-by-step explanation:

Step one:

given data

we are told that the initial bill is $74

thereafter they gave a tip worth 18% of the bill

let us compute what 18% of $74 will amount to

Step two:

=18/100*74

=0.18*74

=$13.32

The added expenses is $13.32

Hence the total cost is

the initial bill plus the tip

=74+13.32

=$87.32

Answer:

Step-by-step explanation:

Given ratio of boys and girls in the class =7:5

No of boys is 8more than the girls

So

Let no of boys in the class =7x

No of girls in the class=5x

7x=5x+8

2x=8

X=8/2

X=4.

Total strength =no of boys + no of girls

=7x+5x

=7×4+5×4

= 28+20

=48.

Total strength in the class is 48.

Answer:

Total class strength = 48

Step-by-step explanation:

Boys : Girls = 7 : 5

Number of boys  = 7x

Number of girls = 5x

7x - 5x = 8

      2x = 8      

       x = 8/2

       x = 4

Total strength = 7x + 5x = 12x = 12*4  = 48
