Without using mathematical tables,find 6log(x+4)=log64

Answer:

UW = 67

Step-by-step explanation:

In order to find UW, we need to add UV and VW because them together makes the entire line, also known in this problem as UW. This is our equation:

UV + UV = UW

This is the equation if you plug the numbers:

19 + 4x - 20 = 6x - 35

Combine like terms to make it easier to do the math:

4x - 1 = 6x - 35

Then do the math:

(4x - 4x) -1 = (6x - 4x) - 35

-1 = 2x - 35

(-1 + 35) = 2x (- 35 + 35)

34 = 2x

34/2 = 2x/2

x = 17

Then you plug in x for the UW expression:

6x - 35

6(17) - 35

102 - 35

67

UW = 67

Answer:

7.3

Step-by-step explanation:

The length of AB is found using the distance formula

We need to know the coordinates of A and B

A = (-5,-4) and B = (-3,3)

The distance is

d = sqrt ( (y2-y1)^2 + (x2-x1)^2)

   = sqrt( (3 - -4)^2 +(-3 - -5)^2)

   = sqrt( (3+4)^2 +(-3+5)^2)

   = sqrt(7^2+2^2)

   = sqrt(49+4)

  = sqrt(53)

  =7.280109889

To the nearest hundredth

 =7.3

Step-by-step explanation:

AB is the hypotenuse of the right triangle

sin34 = opp/hyp = 29/hyp

hyp = 29/sin34 = 51.860457849...

Answer:

[tex]let \: |ab| \: be \: x \\ \\ \frac{ \sin(90) }{x} = \frac{ \sin(34) }{29} \\ x \sin(34) = 29 \sin(90) \\ x = \frac{29 \sin(90) }{ \sin(34) } \\ x = 51.86(2.d.p) \\ |ab| = 51.86[/tex]

Answer: to the nearest tenth i believe, 6.8

Step-by-step explanation:

The round off should be ones place.

Rounding off means a number is made simpler by keeping its value intact but closer to the next number. It is done for whole numbers, and for decimals at various places of hundreds, tens, tenths, etc.

Given:

20÷3

The resulting value is 6.666666667.

So, divide the money it should be round off to ones place to get a whole number which can make it easy to divide.

Hence, the round off should be ones place = 7

Answer:

36

Step-by-step explanation:

Replace the 2b with 10 and then do the parenthesis, so 10-4=6

now multiply it with the 6 outside the parenthesis and you get 36

Hi! I'm happy to help!

First of all, we need to substitute b into the expression.

6(2b-4)

6((2×5)-4)

Now we use the order of operations, or PEMDAS (Parenthesis, Exponents, Multiplication or Division, and Addition or Subtraction) to finish simplifying.

We see that 2×5 is inside two sets of parenthesis, so we solve that first

6((2×5)-4)

6((10)-4)

We cam remove the extra set of parenthesis because there isn't an expression inside of it any more.

6(10-4)

Now, we look inside of the parenthesis again and we see 10-4

6(10-4)

6(6)

The six next to the parenthesis has no sign next to it, which means to multiply.

6×(6)

Now we can remove the parenthesis.

6×6

Now, we just simply multiply.

6×6

36

To sum it up: The value of 6 (2b-4) When b=5 is 36

Answer:

The 70% mixture makes up 0.7 liters of the solution whereas the 60% mixture makes up 2.8 liters of the solution.

Step-by-step explanation:

Let us have x liters of the .7 mixture and y liters of the .6 mixture.

We want total liters to be 3.5 which means we need x+y=3.5 . I don't like the decimal in the equation so I'm going to multiply both sides by 10: 10x+10y=35

We also need the .7x+.6y=.62(3.5) . I hate the decimal business going on in this question so I'm going to multiply by 1000 which gives 700x+600y=62(35) .

So we have the system

700x+600y=62(35)

10x+10y=35

I'm going to setup this up for linear combination/elimination.

Multiply bottom equation by 60.

700x+600y=62(35)

600x+600y=60(35)

Subtract equations (bottom from top):

(700-600)x+(600-600)y=35(62-60)

Simplify:

100x+0y=35(2)

100x=70

Divide both sides by 100:

x=70/100

x=7/10

Going back to x+y=3.5 along with x=7/10 or .7 liters to find y.

y=3.5-x with x=.7

y=3.5-0.7

y=2.8

The 70% mixture makes up 0.7 liters of the solution whereas the 60% mixture makes up 2.8 liters of the solution.

Pic added.

Another way to do problem:

.7x+.6(3.5-x)=.62(3.5)

Multiply and distribute:

.7x+2.1-.6x=2.17

Combine like terms on left:

.1x+2.1=2.17

Subtract 2.1 on both sides:

.1x=.07

Multiply both sides by 10:

x=0.7 liters

Now the other acid solution is 3.5-0.7 which is 2.8 litera.

B. -4/6

Step-by-step explanation:

5x+x=-4

6x=-4

x=-4/6

Answer:

Step-by-step explanation:

If you are solving for x then you should get something like this

A 5x-2+x=x- 4 B. 5x+x=x-4

6x-2=-4. 6x=x-4

6x-2-x=-4. 6x-x=-4

5x-2+2=-4+2. 5x=-4

5x/5=-2/5. 5x/5=-4/5

x=-2/5. x=-4/5
