Answer:

Width = 7 cm.

Step-by-step explanation:

Create your equation. 2x + 2(2x + 17) = 76

Distribute 2 to 2x and 17. 2x + 4x + 34

Combine like terms. 6x + 34 = 76

Subtract 34 from both sides.

6x = 42

Divide both sides by 6.

x = 7

Is -6.175 is an irrational number?
kipiarov [429]
No.

Any number you can write completely is a rational number.
Any number with a repeating decimal fraction is also a rational number.
___
Any number that goes on forever without repeating is an irrational number. These are usually represented symbolically (because they cannot be written "exactly" any other way). These include such numbers as √2, π, e, ∛(-4), and an infinite number of others.

The equation of line A is y = 7x + 12. Line B is perpendicular to line A and passes through the point . What would be the soluti
max2010maxim [7]
Since B is perpendicular to A. We can say that the gradient of B will be -1/7 (product of the gradients of 2 perpendicular lines has to be -1).
Now we know that the equation for B is y=-(1/7)x + c with c being the y intercept.
Since the point isnt specified in the question, we could leave the equation like this.
But if there is a given point that B passes through, just plug in the x and y values into their respective places and solve to find c. That should give you the equation for b.
Now, to find the solution of x, we have 2 equations:
1) y=7x+12
2)y=-(1/7)x+c

In this simultaneous equation we see that y is equal to both the expressions. So,
7x+12=-(1/7)x+c

Now, since the value of c is not found, we cannot actually find the value of x, but if we would find c, we could also find x since it would only be a matter of rearranging the equation.
And there you go, that is your solution :)

A pentagon has an 80° angle and 100° angle. The remaining three angels have a ratio of 2:3:4. The measure of the largest angle,
Genrish500 [490]

Answer:

140,150

Step-by-step explanation:

The sum of the angles in a polygon is

180(n−3)

For a pentagon, this equals 540. Since the first 3 angles add up to 240, the remaining 2 angles must add up to 540−240=300∘
