True or false 5.020=5.20 please help

Answer:

The value of x is 12.

Step-by-step explanation:

Given that perimeter is found when all sides are added together. So we can assume that all side lengths add together will give you 134 imches :

[tex]x + 2x + 5 + 6x - 17 + 3x + 2 = 134[/tex]

[tex]12x - 10 = 134[/tex]

[tex]12x = 134 + 10[/tex]

[tex]12x = 144[/tex]

[tex]x = 144 \div 12[/tex]

[tex]x = 12[/tex]

Answer:

X=12

Step-by-step explanation:

x+2x+5+6x-17+3x+2=134

12x-10=134

12x=144

x=12

Answer:

5.0587

Step-by-step explanation:

First, you have to count to the fourth number after the decimal;

That number is 7, the number after it is the one that will help you round.

Since that number is 0 you round down to 7.

Answer:

5.0587

Step-by-step explanation:

So we look at 5.05870

we count to four after the decimal place and land on the seven, next we look at the digit behind to seven to determine if we can round (remember 5 or more round the score, four or less let it rest).

Answer: If the center of rotation is changed, the pentagon maps back onto itself only one time, when the value of a is 360 degrees that is, when the pentagon completes a full rotation.  (just a heads up if your going to copy and paste, change it up a bit because this is word for word :) hope it helped!)

Answer:

If the center of rotation is changed, the pentagon maps back onto itself only one time, when the value of α is 360°—that is, when the pentagon completes a full rotation.

Answer:

- 1

Step-by-step explanation:

Step 1:

3 ( x - 2 ) + 4 = 2x - 1        Equation

Step 2:

3x - 6 + 4 = 2x - 1      Multiply

Step 3:

3x - 2 = 2x - 1     Combine Like Terms

Step 4:

3x = 2x - 1 + 2   Add 2 on both sides

Step 5:

3x = 2x - 1    Combine Like Terms

Step 6:

x = - 1     Subract 2x on both sides

Answer:

x = - 1

Answer:

a) (-3/2,0), (0,-10)

Step-by-step explanation:

y = mx + b

Change the equation to y intercept form.

-3x - 2y = 20

Isolate -2y by adding 3x on both sides.

-2y = 3x +20

Divide everything by -2

y = [tex]-\frac{3}{2}x[/tex] - 10

If you have a ti 84 plus calculator put it in the calculator:

go to y =

then press 2nd graph

then press graph

you will be at the (x,y) table  

look at what (x,y) value match your choices.

Another way to solve this equation is to substitute.

a) is the correct choice

Answer:

x = [tex]\frac{7}{2}[/tex]

Step-by-step explanation:

Given

[tex]\frac{5}{4}[/tex] + [tex]\frac{x}{2}[/tex] = 3 ( multiply through by 4 to clear the fractions )

5 + 2x = 12 ( subtract 5 from both sides )

2x = 7 ( divide both sides by 2 )

x = [tex]\frac{7}{2}[/tex]

Answer:

equation 0.8C+1=C

4 liters of orange juice

Step-by-step explanation:

C for can

0.8 as 80%

1 for liters of water

0.8C+1=C

subtract 0.8C

1=0.2C

if 1 liter=20% of a can then 80% is 4 liters

Answer: natural; whole; integer; rational; real

Step-by-step explanation:

16/4=4

Natural: numbers that are greater than 0.

4 is greater than 0

Whole: numbers that are equal or greater than 0

4 is equal or greater than 0

Integer: numbers that have no decimal points

4 has no decimal points

Rational: numbers that can be written as fraction

4=16/4 which is fraction

It is already rational, so it will not be irrational.

Real: all number you can name are real number

4 is four

Step-by-step explanation:

We can use the expression (22 x 40) + (22 x 6).

Answer: 8 hundred thousands

Answer:

The value is 800,000

Step-by-step explanation

the 2 is in the thousands spot so that would make the 4 in the ten thousands and the 8 in the hundred thousands.

Answer:

  108°

Step-by-step explanation:

The two given angle are vertical angles, which means they are congruent.

  (x +81)° = 4x°

  81 = 3x . . . . . . . subtract x, divide by °

  27 = x . . . . . . . . divide by 3

  (27 +81)° = 108° . . . . find the angle measure

The two marked angles have measures of 108°.

Answer:

-30%

Step-by-step explanation:

currently, the perimeter is: 4 + 6 + 4 + 6 = 20 in.

when the width of 4 in is decreased by 3 in, the new width become (4-3) in = 1 in

therefore, the new perimeter is: 1 + 6 + 1 + 6 = 14 in

the change in perimeter is: 20 in - 14 in = 6 in

now, the percent of change in perimeter will be:

[tex]\frac{change- in -perimeter}{original -perimeter} *100 = \frac{6}{20}*100 = 30[/tex]%

BUT because this change is a DECREASE, you have to put a NEGATIVE sign before the value to inducate that it's a decrease, so

change in perimeter = -30%

Answer:

f^-1 (x) = x/2 - 1

Step-by-step explanation:

Sprints = $39.99 +&0.45

Verizon= $44.99+$0.40

Step 1: Equate the values

[tex]39.99 + 0.45m = 44.99 + 0.40m[/tex]

Step 2 :Collect like terms and simplify

[tex]0.45m - 0.40m = 44.99 - 39.99 \\ 0.05m = 5[/tex]

Step 3 :Divide both sides of the equation by 0.05

[tex] \frac{0.05m}{0.05} = \frac{5}{0.05} [/tex]

Step 4 :Simplify

Answer: 20.442 seconds

Step-by-step explanation:

From the question, we are informed that Amy ran a race in 20.7 seconds and that Katie finished the race 0.258 second before Amy.

To know how long it took Katie to run the race, we subtract 0.258 seconds from 20.7 seconds. This will be:

= 20.7 - 0.258

= 20.442 seconds

Answer:

-2,-1

Step-by-step explanation:

Solve the following system:

{y = 3 x + 5 | (equation 1)

x = -2 y - 4 | (equation 2)

Express the system in standard form:

{-(3 x) + y = 5 | (equation 1)

x + 2 y = -4 | (equation 2)

Add 1/3 × (equation 1) to equation 2:

{-(3 x) + y = 5 | (equation 1)

0 x+(7 y)/3 = -7/3 | (equation 2)

Multiply equation 2 by 3/7:

{-(3 x) + y = 5 | (equation 1)

0 x+y = -1 | (equation 2)

Subtract equation 2 from equation 1:

{-(3 x)+0 y = 6 | (equation 1)

0 x+y = -1 | (equation 2)

Divide equation 1 by -3:

{x+0 y = -2 | (equation 1)

0 x+y = -1 | (equation 2)

Collect results:

Answer: {x = -2 , y = -1

Answer:

number of baskets would be 3 dollars each from what I see 5 x 3= 15 7x3= 21 9x3=27 Ect

Step-by-step explanation:

Step-by-step explanation:

tan30° = Height of person / (Distance away from river bank + river's width) = 1/√3.

Therefore 1.6m / (2m + x) = 1/√3

By cross multiplication, 1.6√3 = 2 + x.

Hence, x ≈ 0.77m.

Answer:

7[tex]x^{5}[/tex] + 18x³ + 8x

Step-by-step explanation:

Each term in the second factor is multiplied by each term in the first factor, that is

7x³(x² + 2) + 4x(x² + 2) ← distribute both parenthesis

= 7[tex]x^{5}[/tex] + 14x³ + 4x³ + 8x ← collect like terms

= 7[tex]x^{5}[/tex] + 18x³ + 8x

Answer:

3. x = 17

4. a. m<NMP = 48°

b. m<NMP = 60°

Step-by-step explanation:

3. Given that <BAM = right angle, and

m<BAM = 4x + 22, set 90° equal to 4x + 22 to find x.

4x + 22 = 90

Subtract 22 from both sides

4x + 22 - 22 = 90 - 22

4x = 68

Divide both sides by 4

4x/4 = 68/4

x = 17

4. a. m<NMQ = right angle (given)

m<PMQ = 42° (given)

m<PMQ + m<NMP = m<NMQ (angle addition postulate)

42 + m<NMP = 90 (substitution)

m<NMP = 90 - 42 (subtracting 42 from each side)

m<NMP = 48°

b. m<NMQ = right angle (given)

m<NMP = 2*m<PMQ

Let m<PMQ = x

m<NMP = 2*x = 2x

2x + x = 90° (Angle addition postulate)

3x = 90

x = 30 (dividing both sides by 3)

m<PMQ = x = 30°

m<NMP = 2*m<PMQ = 2*30

m<NMP = 60°
