Answer:

14.5

Step-by-step explanation:

2x=7*5-6 will be 14.5

Answer:

One solution.

Step-by-step explanation:

Since the right side of the equation is a constant, there can only be one solution:

[tex]2x+6=7*5[/tex]

[tex]2x+6=35[/tex]

[tex]2x=35-6[/tex]

[tex]2x=29[/tex]

[tex]x=14.5[/tex]

14.5 is the only answer.

Answer:

x=4

y= 1/2

Step-by-step explanation:

The easiest way to solve this is to subtract the two equation from each other

wee have

  4x+2y=17

-  3x+2y=13

___________

x=4

Now that we know what x is we can solve for y

4(4)+2y=17

16+2y=17

2y=1

y= .5

Answer:

answer is 175 miles, have a good day <3

Answer:

x=1

Step-by-step explanation:

you have to put x on one side. send -10 to the other side. Add 10 on both sides to delete 10.

7x-10+10=3x-6+10

now it leaves you with 7x=3x+4

Now you have to send 3x to the other side because you are solving for x. subtract both sides by 3x to delete 3x on the other side.

7x-3x=3x-3x+4

how it leaves you with 4x=4

now you divide both sides by 4

4/4x=4/4

Hence, x=1

Answer:

standard form: 4x - 4 = 0

factorisation: 4(x - 1) = 0

solutions: x = 4/4 = 1

therefore, x is 1

Answer:

-28m+8

Step-by-step explanation:

Combine like terms

(-m + -9m + -8m + -10m) + (8)

Answer:

29 feet

Imagine you are on an open plane.

you walk 11 feet forward and your friend 10 feet. you are now 21 feet apart. now put imaginary walls that stopped both of you at that 21 feet.

now, you go 12 feet to your right, and your friend 8 feet to their right. imagine you are pushing a wall in front of you.

at that point the side walls are 20 feet apart.

you and your friend are at opposite corners of a 20 by 21 foot room.

at that point it's just a matter if applying the Pythagorium theory.

Answer:

the radius of each cylinder is 1 cm, 2 cm and 3 cm respectively

Step-by-step explanation:

The computation of the radius of each cylinder is shown below:

As we know that

The Volume of the cylinder = πr^2h

The radius would be

[tex]=\sqrt{ \frac{V}{\pi h} }[/tex]

For cylinder A

[tex]=\sqrt{\frac{2826}{3.14\times 900} }[/tex]

= 1 cm

For cylinder B

[tex]=\sqrt{\frac{2826}{3.14\times 225} }[/tex]

= 2 cm

For cylinder C

[tex]=\sqrt{\frac{2826}{3.14\times 100} }[/tex]

= 3 cm

Hence, the radius of each cylinder is 1 cm, 2 cm and 3 cm respectively

Answer:

f(x)=320(1.16)^x

Step-by-step explanation:

This is an exponential equation with an initial population at x=0 of 320 (because 1.16^0=1, and 320*1=320) After the first year, there are 371 bunnies. After two years, there are 431, etc etc.

Answer:

f(x)=320(1.16)^x

This is an exponential equation with an initial population at x=0 of 320 (because 1.16^0=1, and 320*1=320) After the first year, there are 371 bunnies. After two years, there are 431, etc etc.

Answer:

[tex]\sin C=\frac{28}{35}[/tex]

Step-by-step explanation:

In a right triangle, [tex]\sin\theta =\frac{\text{opp}}{\text{hyp}}[/tex]. In this case, the side opposite to angle [tex]C[/tex] is 28 and the hypotenuse is 35. Therefore, the exact value of [tex]\sin C[/tex] is [tex]\boxed{\frac{28}{35}}[/tex].

Answer:

Step-by-step explanation:

B = 35      {Alternate interior angles}

C = 75      {Corresponding angles}

D + 75 =  180 {Linear pair}

     D = 180 - 75

     D = 105

A = C   {Corresponding angles}

A = 75

E = A   {Alternate interior angles}

E = 75

Answer:

Nathanial will charge $12

Step-by-step explanation:

If he charges $3 per 15 minutes, one hour is 60 minutes. And 60 divided by 15 is 4 so you do 3x4 because he charges $3 per 15 minutes.

Answer:

s< -7/11

Step-by-step explanation:

Given:

In triangle DEF, HG is parallel to DF.

To find:

The value of x.

Solution:

In triangles DEF and GEH,

[tex]\angle DE F\cong \angle GEH[/tex]          (Common angle)

[tex]\angle EDF\cong \angle EGH[/tex]          (Corresponding angle)

[tex]\Delta DE F\sim \Delta GEH[/tex]             (By AA property of similarity)

We know that corresponding sides of similar triangle are proportional.

[tex]\dfrac{DE}{GE}=\dfrac{DF}{GH}[/tex]

[tex]\dfrac{9+(x+5)}{x+5}=\dfrac{12}{6}[/tex]

[tex]\dfrac{x+14}{x+5}=2[/tex]

[tex]x+14=2(x+5)[/tex]

[tex]x+14=2x+10[/tex]

Isolating variable terms, we get

[tex]x-2x=-14+10[/tex]

[tex]-x=-4[/tex]

[tex]x=4[/tex]

Therefore, the value of x is equal to 4.

Answer:  6:5 ; 18:15 ; 36:30

Step-by-step explanation:

6/5 = x/15

5x = 6(15)            use cross multiply

5x = 90

x = 18

6/5 = 36/x

6x = 5(36)            use cross multiply

6x = 180

x = 30

Answer:

Answer below

Step-by-step explanation:

For every 6 taxis, there are 5 busses

if there are 15 busses, thats 3 sets of 5

6x3 is 18. so for every 15 busses, there are 18 taxis

If there are 36 taxis, thats 6 sets of 6

since there are 5 busses for every 5 taxis

5x6 is 40

for every 30 busses, there are 36 taxis

Answer:

90

Step-by-step explanation:

Divide 72 by 4 you get 18 which is how many Ling baked with one scoop of flour. Then just add 18 to 72 and you get 90

Answer: The speed of the current is 3 miles per hour.

Step-by-step explanation:

Let x = speed of boat , y= speed of current.

Given:

x-y=10         (Upstream)       ...(i)

x+y= 16   (Downstream)       ...(ii)

Adding (i) and (ii), we get

2x=26

⇒ x= 13

Put x=13 in (i), we get

13-y=10

⇒ y=13-10

⇒ y=3

Hence, the speed of the current is 3 miles per hour.
