Answer:

(3,1)

value x is 3

value y is 1

Answer:

w = 18

Step-by-step explanation:

w+6 = 2(w-6)

w+6 = 2w-12

2w-w = 6+12

w = 18

hope it helps

Answer:

[tex] \huge \boxed {w = 18}[/tex]

Step-by-step explanation:

Distribute 2 in the bracket.

[tex]w + 6 = 2w - 12[/tex]

A constant and variable cannot add up or subtract each others. Therefore, move the same term to the same side.

[tex]12 + 6 = 2w - w \\ 18 = w[/tex]

Answer Check

Substitute w = 18 in the equation.

[tex]18 + 6 = 2(18) - 12 \\ 24 = 36 - 12 \\ 24 = 24[/tex]

Therefore w = 18 is the correct answer.

Answer:

There are 8 males in the class and 42 females.

Step-by-step explanation:

This question can be solved using a system of equations.

I am going to say that:

x is the number of females.

y is the number of males.

Class of 50 students

This means that [tex]x + y = 50[/tex]

The number of females is 2 more than 5 times the number of males.

This means that [tex]x = 5y + 2[/tex]

So, finding y, the number of males:

[tex]x + y = 50[/tex]

[tex]5y + 2 + y = 50[/tex]

[tex]6y = 48[/tex]

[tex]y = \frac{48}{6}[/tex]

[tex]y = 8[/tex]

Females:

[tex]x = 5y + 2 = 5*8 + 2 = 42[/tex]

There are 8 males in the class and 42 females.

[tex] \huge \blue{solution}[/tex]

[tex] \bold \red{ \frac{x}{3} - \frac{x}{4} = \frac{x}{6} }[/tex]

[tex] \bold \red{ \frac{4x + 3( - x)}{3 {2}^{2} } = \frac{x}{6} }[/tex]

Answer:

4.2 cm

Step-by-step explanation:

Given

Area of parallelogram (A) = 4.2 cm²

base (b) = 1.75 cm

Height (h) = ?

We know

A = b * h

4.2 = 1.75 * h

h = 4.2 / 1.75

H = 2.4 cm

Answer:

= 56.7 miles per hour

Step-by-step explanation:

Step-by-step explanation:

To find the average speed for the entire journey, we need to find the entire distance   and the  total time

Entire distance = 210 miles + 130 miles = 340 miles

Total time = 3.5 hours and 2.5 hours = 6 hours

Average speed = distance/ time = 340 miles/ 6 hours

                           = 56.66666666666 miles per hour

Rounding to the nearest tenth

                             = 56.7 miles per hour

Answer:

60 miles

Step-by-step explanation:

210=3.5

x =1

3.5×x= 210×1

3.5x=210

3.5x/3.5=210/3.5

x=60

Answer= 60 miles

m=0-4/ -2-0

m=-4/-2

m=2

Answer:

C) 70

Step-by-step explanation:

Since they can only spend a maximum of $600, we can fill that in for c. Now, we can solve the equation for n.

600 = 8n + 40

~Subtract 40 to both sides

560 = 8n

~Divide 8 to both sides

70 = n

Best of Luck!

Answer:

The answer is 6

Step-by-step explanation:

First nothing us negative, so multiply 8/4 times 9/3,which is 72/12=6, 6×12 is 72.The reason why it is 9/3 instead of 3/9 is because you are dividing so KCF, keep change flip.

Answer:

Positive 6

Step-by-step explanation:

What you do is:

8 x 9 = 72

-4 x (-3) = 12

72 / 12 = 6

Answer:

point - slope form

 y - 1 = 3 (x-0)

Step-by-step explanation:

step(i):-

Given points are (0,1) and (2,7)

The slope of the line

     [tex]m = \frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]

    [tex]m = \frac{y_{2}-y_{1} }{x_{2} -x_{1} } = \frac{7-1}{2-0} = \frac{6}{2} = 3[/tex]

  m =3

Step(ii):-

point -slope form

   y - y₁ = m(x-x₁)

Equation of the straight line passing through the point (0,1) and having slope 'm' = 3

   y - 1 = 3 (x-0)

  y -1 = 3x

 3x - y +1=0

Equation of the straight line passing through the point (0,1) and having slope 'm' = 3 is 3x -y +1=0
