Answer:

Joshua is 11 and Mckay is 10.

Answer:

x=7

Step-by-step explanation:

Ok so first off, the x variable being in absolute value form will not change the outcome of the problem at all since there are no other x variables in the equation.

x-2=5

(add 2 on both sides)

x=7

Answer: 78

Explanation: Whenever we deal with an evaluation problem, make sure to always use parenthses when substituting numbers in for variables.

Notice that we have a set of parenthses in our original problem.

To avoid the confusion of having too many sets

of parenthses, let's change the parenthses to brackets.

So we have 2(3) [(5) + 8].

Simplifying from here, we have (6) [(13].

Multiplying, we get 78.

Answer:

( 5, 3/2 )

x = 5

y = 3/2

Step-by-step explanation:

5x - 4y = 19

x + 2y = 8

-------------------

2(x + 2y = 8) = 2x + 4y = 16

----------------------

5x - 4y = 19

2x + 4y = 16

7x = 35

÷7    ÷7

x = 5

-----------------------

x + 2y = 8

5 + 2y = 8

-5          -5

2y = 3

÷2   ÷2

y = ( 3/2 )

The true solution of the  [tex]\rm 3log2+log8=2log(4x)[/tex]  is 2.

It is given that the:

[tex]\rm 3log2+log8=2log(4x)[/tex]

It is required to find the value of [tex]\rm x[/tex].

It is another way to represent the power of numbers ie.

Answer:

D

Step-by-step explanation:

4x - 12 - x  ≥ 3

Add 12 to both sides.

4x - x ≥ 15

Subtract x (or 1x) from 4x

4x - x = 3x

3x ≥ 15

Divide both sides by 3.

x ≥ 5

Answer:

-2.8 or -14/5

Step-by-step explanation:

To divide one fraction by another, there is a really cool method called Keep Change Flip

Keep the first fraction

Change the division sign to multiplication

Flip the numbers on the last fraction

Let's try it out.

Keep the 1/5

Change the ÷ to a ×

Flip the -1/14 to a -14/1

1/5 × -14/1

Multiply the top numbers by each other first

1 × -14 = -14

Now the bottom numbers

5 × -1 = -5

The fraction we have now is -14/5

It can also be written as -2.8

The fraction which represent the number of sweaters Maggie knits in 8 days is 2/1 sweaters

Total number of sweaters Maggie knits = Sweaters Maggie knits per day × Number of days

= 1/4 × 8

= (1 × 8) / 4

= 8/4

= 2/1 sweaters

Answer:

x^3+2x+2+2/x

Step-by-step explanation:

Answer:

  42°, 48°

Step-by-step explanation:

Complementary angles have a sum of 90 degrees. This lets us write the relation ...

  x + (x +6) = 90 . . . . . where x represents the angle; x+6 is its complement

  2x = 84 . . . . . . . collect terms, subtract 6

  x = 42 . . . . . divide by 2

  x +6 = 48 . . . . find the complementary angle

The two angles are 42° and 48°.

Answer:

Supplementary angles

Step-by-step explanation:

The two angles shown are supplementary. You can see if the 3x+15 were to slide down to the next line, how the 3x+15 and 2x would make up a linear pair. Together they add up to 180°

Not sure if you need it, but to solve for x:

3x+15 + 2x = 180

combine like terms.

5x + 15 = 180

Subtract 15.

5x = 165

divide by 5

x = 33

Then you can find the measures of the angles.

3(33)+15

= 114°

2(33)

=66°

A 120° angle and the side lengths can form more than one unique triangles

Malik's claim about the triangle is true

From the question, we have Malik's claim to be:

A 120° angle and side lengths of 3 cm and 4 cm can form more than one unique triangle

The above claim is true;

This is so because, the 120 degrees angle can be between the side lengths of 3 cm and 4 cm and the angle can be located not between the side lengths

This means that there are at least two unique triangles that can be formed using the given parameters

Hence, Malik's claim about the triangle is true

Answer:

x = 7

y = 7√3

Step-by-step explanation:

Formulas : -

sin θ = opposite side / hypotenuse

When θ = 60,

Opposite side = y

Hypotenuse = 14

sin 60 = y / 14

√3 / 2 = y / 14

y = √3 x 14 / 2

= √3 x 7

y = 7√3

When θ = 30,

Opposite side = x

Hypotenuse = 14

sin 30 = x / 14

1 / 2 = y / 14

x = 1 x 14 / 2

= 1 x 7

x = 7

Note : -

The value of,

sin 30 = 1 / 2

cos 60 = 7√3

A train is moving at a uniform speed of 80 kilometre per hour.

a) how far will it travel in 15 minutes

b) find the time required to cover a distance of 250 km. { as per direct and inverse propositions}.

a)

Given that the train is moving at a uniform speed of 80 km/h.

Time taken = 15 minutes

First we will convert the time

[tex] \small \sf Time \: taken = 15 min = \dfrac{ \cancel{15}}{ \cancel{60}}hr = \dfrac{1}{4}hr [/tex]

Now we will calculate the distance

We know,

[tex] ✪ \: \small\boxed{ \frak{ {Distance }= {Speed} × Time }}[/tex]

Substituting the values in the given formula

[tex] \small\sf{ Distance = \cancel{ 80} \: \: 20 \: km/ \cancel{ hr} × \dfrac{1}{ \cancel{4}} \cancel{hr} =20km }[/tex]

Distance covered in 15 minutes = 20 km

[tex] \rule {40mm}{2pt}[/tex]

b)

Given that the train is moving at a uniform speed of 80 km/h.

Distance covered = 250 km

Calculating the time

We know,

[tex] ✪ \: \small\boxed{ \frak{ Time = \dfrac{Distance}{Speed}}}[/tex]

Substituting the values in the given formula

[tex] \small\sf{ Time = \dfrac{250 km}{80 km/hr} =3 \: hrs \: 20 \: mins }[/tex]
