Step-by-step explanation:

6x - 3 + 3x = 60 + 2x

Combine like terms:

6x - 3 + 3x = 60 + 2x

9x - 3 = 60 + 2x

-2x                -2x

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

    7x - 3 = 60

Answer:

9

Step-by-step explanation:

to solve this equation you first have to group the like terms

6x-3+3x=60+2x

6x+3x-2x=60+3

7x=63

then you divide both sides by 7 inorder to remain with the variable x on one side

7x/7=63/7

x=9

Answer:

AB = 4

Step-by-step explanation:

AB + BC = AC

Substitute the line segments for their given values:

AB + 38 = 42

Subtract both sides by 38:

AB = 42 - 38

AB = 4

Check your work:

4 + 38 = 42

42 = 42

Correct!

Answer:

square both sides

I.e,tan²0=3

from,tan²0 +sec²0 = 1

so,tan²0=1-sec²0

1 - sec²0=3

sec²0 = 1 - 3

sec²0=-2

square root both sides

Step-by-step explanation:

Bottom triangle

Area = b * height

b = 4 + 4 = 8 cm

h = 5.75

Area = 1/2 * 5.75 * 8

Area = 23 cm^2

Trapezoid

b1 = 8

b2 = 4

h = 2

Area = (b1 + b2)*h/ 2

Area = (8 + 4)*2 /2

Area = 12

Total area = 23 + 12

Total area = 35

We have that the total length of paper needed to cover all the tables is

[tex]X=288.5ft[/tex]

From the question we are told that:

Number of tables [tex]n=36[/tex]

Length of table[tex]l=8[/tex]

Extension [tex]e=3 inch =>0.25feet[/tex]

Generally, the equation for the Total length  tables is mathematically given by

[tex]l_t=n*l\\\\l_t=36*8[/tex]

[tex]l_t=288ft[/tex]

Therefore with an extension of 0.25ft at both end we have the Total length of  tablecloths to be

[tex]X=l_t+2(e)\\\\X=288ft+2(0.25)[/tex]

[tex]X=288.5ft[/tex]

In conclusion

The total length of paper needed to cover all the tables is

[tex]X=288.5ft[/tex]

6

brainliest is appreciated

If x = 2y then, 5y - x in terms of y is equal to 3y and when y = 2, the value of 5y - x is 6.

To solve 5y - x in terms of y, we need to substitute the value of x in terms of y. Given that x = 2y, we can replace x with 2y in the expression 5y - x:

5y - x = 5y - (2y)

Now we simplify the expression by subtracting 2y from 5y:

5y - (2y) = 3y

Therefore, 5y - x in terms of y is equal to 3y.

To find the value of the expression when y = 2, we substitute y = 2 into the expression:

3y = 3 * 2 = 6

Thus, when y = 2, the value of 5y - x is 6.

Answer:

Step-by-step explanation:

Given information

x = 2

Given expression

2y - 5x + 10 = 0

Substitute values into the expression

2y - 5(2) + 10 = 0

Simplify by multiplication

2y - 10 + 10 = 0

2y = 0

Divide 2 on both sides

2y / 2 = 0 / 2

[tex]\boxed{y=0}[/tex]

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

Given information

y = 5

Given expression

2y - 5x + 10 = 0

Substitute values into the expression

2(5) - 5x + 10 = 0

Simplify by multiplication

10 - 5x + 10 = 0

20 - 5x = 0

Add 5x on both sides

20 - 5x + 5x = 0 + 5x

20 = 5x

Divide 5 on both sides

20 / 5 = 5x / 5

Please let me know if you have any questions

Answer:

(i) x = 2

Substituting value in the equation,

2y - 5(2) + 10 = 0

2y - 10 + 10 = 0

2y = 0

y = 0

(ii) y = 5

Substituting value in the equation,

2(5) - 5x + 10 = 0

10 - 5x + 10 = 0

20 - 5x = 0

20 = 5x

5x = 20

x = 20/5

Bisectors are lines that divide an angle into two equal parts. The value of x of OQ is equal to PO is 8

Bisectors are lines that divide an angle into two equal parts. If RS is the segment bisector and given the following parameters:

OQ = 32

PO = 4x,

This shows that OQ = PO that is:

32 = 4x

Swap

4x = 32
x = 8

Hence the value of x of OQ is equal to PO is 8

Answer:

[tex]y=2x-5[/tex]

Step-by-step explanation:

Hi there!

Slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)

We're given that the slope is 2. Plug this into [tex]y=mx+b[/tex] as m:

[tex]y=2x+b[/tex]

Now, to solve for the b, plug in the point (4,3):

[tex]3=2(4)+b\\3=8+b\\3-8=b\\-5=b[/tex]

Therefore, the y-intercept is -5. Plug this back into [tex]y=2x+b[/tex] as b:

[tex]y=2x+(-5)\\y=2x-5[/tex]

I hope this helps!

(x,y) = (4,3)

m = 2

We know that

y = 2x + b

3 = 2(4) + b

3 = 8 + b

3 - 8 = b

-5 = b

Now

We need to find the equation

Equation = y = 2x + b

We have

x = x

y = ?

b = -5

y = 2(x) + (-5)

y = 2(x) - 5

y = 2x - 5

Option C is exactly correct.

We are given,

[tex] \longrightarrow 0.2(10 - 5c) = 5c - 16 [/tex]

Solving the parenthesis

[tex]{ \longrightarrow 0.2 \times 10 - 0.2 \times 5c = 5c - 16 }[/tex]

[tex]{ \longrightarrow 2 - 1c = 5c - 16 }[/tex]

[tex]{ \longrightarrow 2 + 16 = 5c + 1c }[/tex]

[tex]{ \longrightarrow 18 = 6c }[/tex]

Dividing both sides by 6

[tex]{ \longrightarrow 3 = c }[/tex]

Hence c = 3.
