Genuilly I think you’re correct

sorry if it wrong

but, it looks correct and I think it’s correct

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:

[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:

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:

7:9 = x:4878

4878/9 times 7

3794 would be your answer

Answer:

3,794 rupees

Step-by-step explanation:

Johny got 7 parts of the benefit while Rahul got 9. This can be represented as a fraction: 7/9

To solve this problem, we can use cross multiplication, where x represents the amount of rupees Johny got:

[tex]\frac{7}{9}[/tex] = [tex]\frac{x}{4878}[/tex]

Multiply 7 by 4,878: 34,146

Multiply 9 by x: 9x

Now the equation looks like this:

9x = 34,146

Divide both sides of the equation by 9 to isolate the x:

9x/9 = 34,146/9

x = 3,794

Johny got 3,794 rupees.

Answer:

Step-by-step explanation:

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:

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

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:

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 .

please dont count on me but 0.23856062736

Answer:

y = 9x

Step-by-step explanation:

You can set up linear equations like this: y = mx + b, where m is the slope or rate, and b is the y-intercept.

9 would be the slope, since he has to pay $9 per gift.

The y-intercept is when x = 0, but if he doesn't buy any gifts, he won't have to pay anything, so b = 0. You don't have to include it since it's 0.

So, it's just y = 9x

Hope that helps! :D

Answer:

easy

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:

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:

12

Step-by-step explanation:

MARK BRAINLIEST plz

I would have put C. Because if you look at the triangle it makes then do the math with squared numbers then you should get c.
