Answer:

[tex]x=1[/tex]

Step-by-step explanation:

Step 1:  Cross-Multiply

What cross multiply basically means is that you take both sides of the equation and you multiply my the opposite sides.  So you take the top of the left fraction and multiply it by the bottom of the right fraction.  You then have an equal sign and then have the bottom of the left fraction multiplied by the top of the right fraction.

[tex]\frac{2}{7}=\frac{6x}{4x+17}[/tex]

[tex]2(4x+17)=7(6x)[/tex]

Step 2:  Distribute

[tex]2(4x+17)=7(6x)[/tex]

[tex](2*4x)+(2*17)=(7*6x)[/tex]

[tex]8x+34=42x[/tex]

Step 3:  Subtract 8x from both sides

[tex]8x + 34- 8x = 42x - 8x[/tex]

[tex]34=34x[/tex]

Step 4:  Divide both sides by 34

[tex]34/34 = 34x/34[/tex]

[tex]1=x[/tex]

Answer:  [tex]x=1[/tex]

Answer:

[tex]\frac{14}{27}[/tex]

Step-by-step explanation:

[tex]\frac{3}{2}[/tex]×[tex]\frac{9}{7}[/tex] = [tex]\frac{27}{14}[/tex]

Reciprocal of [tex]\frac{27}{14}[/tex] = [tex]\frac{14}{27}[/tex]

For finding reciprocals of fractions, simply flip the numerators and denominators.

Answer:

14/27

Step-by-step explanation:

[tex](3 \div 2 \times 9 \div 7 )\\ 27 \div 14 \\ reciprocal = 14 \div 27[/tex]

Answer:

Y = 50 + 65w

Step-by-step explanation:

Answer:

3x +y = 13

Or, x=13-y/3......eqn(i)

Now putting the value of x

2x - y = - 1

Or, 2(13-y/3) - y = - 1

Or, 26 - 2y /3 - y = -1

Or, 26 - 2y - 3y = - 3

Or, 26 - 5y = - 3

Or, - 5y = - 3 - 26

Or,y = - 39/ (- 5)

Or, y = 7.8~

Answer:

x = 17.7

Step-by-step explanation:

[tex]a^{2} + b^{2} = c^{2}[/tex]

[tex]7.5^{2} + 16^{2} = x^{2}[/tex]

[tex]56.25 + 256 = x^{2}[/tex]

[tex]312.25 = x^{2}[/tex]

[tex]\sqrt{312.25} = x[/tex]

[tex]17.7 = x[/tex]

Answer: Yes it is

Step-by-step explanation:

A linear relationship simply put, is a relationship between variables that when constructed, forms a straight line. This happens when y changes at a constant rate if x changes by a constant rate as well for instance, 1.

From this question, assume x is minutes and y is the total number of pieces put together. This means that every time x (minutes) increases by 1, y increases by 5 pieces.

The formula would look like this;

y = 5x + 253

This is a formula for a straight line so indeed, this relationship is linear.

Answer:

A) 6

Step-by-step explanation:

x + 8 > 15

x > 15 - 8

x > 7

8, 10, and 12 are all greater than 7. 6 is NOT

Answer: is A because 6+8=14 when the rest of the choices are bigger then 15

Answer:15

Step-by-step explanation:

Answer:

The domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes. (In grammar school, you probably called the domain the replacement set and the range the solution set.

Step-by-step explanation:

Answer:

a) 3x + y = -5 & b) y = 1/3 ( 21- 9x )

Step-by-step explanation:

a)

3x + y = -5

y = -3x -5

b)

y = 1/3 ( 21 - 9x)

y = -3x + 7

y = 3x + 2.5

the slop is to be same in the parallel lines. slop means m in ( y = mx + c )

so a) & b) are parallel lines. since their m is -3 .

Answer:

1/3 and 5/15

Step-by-step explanation:

Solution:

It is given that :

Area of old crate = 8 square feet

Area of the new crate = 12 square feet

Therefore difference in the area = 12 - 8

                                                     = 4 square feet

Now the percentage increase in the area of the crate is given by :

[tex]$=\frac{\text{difference in the area of crate}}{\text{original area of crate}} \times 100$[/tex]

[tex]$=\frac{4}{8} \times 100$[/tex]

= 50%

So the percentage increase in space is 50%

Answer:

111

Step-by-step explanation:

You know the angle missing in the triangle is 69 (180-75-36). The angle on a line is 180. So 180-69=111.

OR

Add the two given angles to get 111 as 75+36+(180-x)=180 so if you subract (180-x) it leaves 75+36.

Answer:

Sin^2A-sin^2B

Step-by-step explanation:

(sin A + sin B) (sin A-sin B)

=SinA(sinA-sinB)+SinB(sinA-sinB)

=Sin^2A-sinAsinB+sinBSinA-sin^2B

=Sin^2A-sin^2B
