Answer:

x = 2.4

I'm not sure how the answer is 4.5 but I'm pretty sure this is right unless I'm missing something

Step-by-step explanation:

So we need to find how much shorter is the short line compared to the longer one. Basically we need a scale factor, for this we can use the side lengths already given to us, 10 and 15. So u can choose either enlarge the short line or shorten the longer one.

If u want to enlarge the short line then do 15/10 which is 3/2 which u will then multiply the shorter line's equation with it, if u want to shorten the longer line then do 10/15 which is 2/3 and multiply the longer lines equation with it.

I'll be using the 3/2 one cause why not:

3/2(x + 6) = 4x + 3

3/2x + 18/2 = 4x + 3

multiply the entire equation with 2 to make 3/2 no longer a fraction

(3/2x + 18/2 = 4x + 3)2

6/2x + 18 = 8x + 6

3x + 18 = 8x + 6

subtract 18 from both sides

3x = 8x - 12

subtract 8x from both sides

-5x = - 12

divide -5 from both sides

x = 2.4

U can input x into the equation to check:

3/2(2.4 + 6) = 4(2.4) + 3

12.6 = 12.6, it's right

Answer:

-5x > 10

Step-by-step explanation:

1. We know that when -14 thrown to the right hand side, it will turn to +14

2. +14 -4 = +10

3. Left hand side will remain -5x

4. Hence, -5x > 10

5. and the equation divided by -5, the > sign will change to <

6. x< -2

7. Since you're finding the missing step so it's -5x > 10

Answer:

A liter of milk cost $0.75 and a loaf of bread cost $1.75

Step-by-step explanation:

Let the liters of milk by represented by m

Let the loaves of bread by represented by b

Bhavik bought 3 liters of milk and 5 loaves of bread for a total of $11

3m + 5b = 11...... Equation 1

A month later, he bought 4 liters of milk and 4 loaves of bread at the same prices, for a total of $10

4m + 4b = 10.... Equation 2

Combining the Equations

3m + 5b = 11...... Equation 1

4m + 4b = 10.... Equation 2

We solve using the Elimination method

Multiply Equation 1 by 4 and Equation 2 by 3 to eliminate m

12m + 20b = 44..... Equation 3

12m + 12b = 30....... Equation 4

Substract Equation 4 from Equation 3

8b = 14

b = 14/8

b = $1.75

Solving for m

3m + 5b = 11...... Equation 1

3m + 5($1.75) = 11

3m + $8.75 = $11

3m = $11 -$ 8.75

3m =$ 2.25

m =$ 2.25/3

m = $0.75

Therefore,

a liter of milk cost $0.75 and a loaf of bread cost $1.75

Answer:

80%

Step-by-step explanation:

home work = 10%

project grade = 50%

final exam = 40%

so

homework  = 72

100=10

72=?      cross multiply and get 7.2%

project grade = 80

100 = 50

80 = ?   cross multiply and get 40%

final exam = 82

100 = 40

82 = ?     cross multiply and get 32.8%

then add them altogether getting a total of 80%.

Answer:

BCE= 115    ECD=65

Step-by-step explanation:

(5x+10)+(3x+2)=180

8x+12=180

8x=168

x=21

5(21)+10=115

3(21)+2=65

Answer:

<BCE=115°

<ECD=65°

And their sum is 180°

Step-by-step explanation:

< BCE + <ECD =180° ( Being sum of supplementary angle which is formed in the given diagram is 180°)

(5x + 10)° + (3x + 2)°= 180°

5x + 10 + 3x + 2 = 180°

5x + 3x + 10 +2 = 180°

8x + 12= 180°

8x = 180°-12°

8x = 168

x= 168/8

x=21°

Now,

<BCE = 5x+10

= 5*21+10

=105+10

=115

<ECD

= 3x+2

= 3*21+2

=65

i looked this up and this is what i got

Answer:

48.5 km/h

Step-by-step explanation:

speed = distance/time

distance =56km

time = 1814h - 1722h

time = 52 min = 52/60h =13/15h

speed = 56*13/15

speed = 48.53

into 1dp= 48.5 km/h

Answer =

So first remember the formula:

Distance/Time= Speed.

Now you see how many minutes it is from 17:22 to 18:14.

17:22 > 18.14 = 52 minutes, 1 Hour = 60 minutes. Hence, 52/60.

Then you get your calculator and do, 56 km/ 52/60

So what I mean is basically 56 km *fraction line* 52 *another fraction line* and then 60 in your calculator. Then you will get a fraction then press SD in your calculator.

You should get 64.6153....

Now the final step is to round it to the 1st decimal place, so

64.6|153 after 64.6 is the first decimal place which is (1) and 1 is below 5 so it will not go up and therefore stay the same so, your Answer is: 64.6 km/h.

Hope it helped!

The quotient to describe the rate of change in the squirrel’s height above the ground is 27.619 feet per seconds to the nearest hundredth.

Given data

height below ground = 45 feet

height above the ground = 100 feet

time of travel = 5.25 seconds

Rate of change calculation

total distance moved by the squirrel = height below ground + height above the ground

= 45 feet + 100 feet

= 145 feet

rate of change = total distance / time of travel

= 145 feet / 5.25 seconds

= 27.619 feet per seconds

Given:

The value is tan(195°).

To find:

The exact value of tan(195°).

Solution:

We have,

[tex]\tan (195^\circ)=\tan (180^\circ+15^\circ)[/tex]

[tex]\tan (195^\circ)=\tan (15^\circ)[/tex]      [tex][\because \tan (180^\circ-\theta)=\tan \theta][/tex]

It can be written as

[tex]\tan (195^\circ)=\tan (45^\circ-30^\circ)[/tex]

[tex]\tan (195^\circ)=\dfrac{\tan (45^\circ)-\tan (30^\circ)}{1+\tan (45^\circ)\tan (30^\circ)}[/tex]      [tex][\because \tan (A-B)=\dfrac{\tan A-\tan B}{1+\tan A\tan B}][/tex]

[tex]\tan (195^\circ)=\dfrac{1-\dfrac{1}{\sqrt{3}}}{1+(1)(\dfrac{1}{\sqrt{3}})}[/tex]

[tex]\tan (195^\circ)=\dfrac{\dfrac{\sqrt{3}-1}{\sqrt{3}}}{1+\dfrac{1}{\sqrt{3}}}[/tex]

[tex]\tan (195^\circ)=\dfrac{\dfrac{\sqrt{3}-1}{\sqrt{3}}}{\dfrac{\sqrt{3}+1}{\sqrt{3}}}[/tex]

[tex]\tan (195^\circ)=\dfrac{\sqrt{3}-1}{\sqrt{3}+1}[/tex]

Therefore, the exact value of tan(195°) is [tex]\dfrac{\sqrt{3}-1}{\sqrt{3}+1}[/tex].
