Answer:
9
Step-by-step explanation:
We can set up a systems of equations to find the value of the third side.
Let's assume that [tex]x[/tex] is the length of both sides 1 and 2. Let's also assume that [tex]y[/tex] is the length of the third side.
We know that [tex]x + x + y = 23[/tex], and looking at the first clue we can make the equation [tex]y = 2x-5[/tex].
We can substitute y into the equation [tex]x + x + y = 23[/tex].
[tex]x + x + (2x-5) = 23\\\\2x + 2x-5 = 23\\4x-5 = 23\\4x = 28\\x = 7[/tex]
So the length of the side that is the same as the second is 7.
Now we can plug this into the equation [tex]y = 2x-5[/tex] to find [tex]y[/tex].
[tex]y = 2(7) - 5\\\\y = 14-5\\\\y = 9[/tex]
Hope this helped!
Answer:
9 cm
Step-by-step explanation:
Let's say that the length of the 2 equal sides is x.
That means:
Side 1 = x
Side 2 = x
We know that the third side is 5 less than twice the length of the 2 equal sides, or 2x-5
Side 3 = 2x-5
The perimeter is all sides together.
Side 1 + Side 2 + Side 3
We know the length of each side, so let's put that in instead.
x + x + 2x-5
Let's simplify this expression:
x + x + 2x - 5
2x + 2x - 5
4x - 5
We know the perimeter, 4x-5, is 23 cm.
4x - 5 = 23
4x = 28
x = 7
The third side is 2x-5. If x is 7...
2*7 - 5 = 14-5 = 9
Answer: 9 cm

2x-15=3(2x+3)
It’s multi step equations
Answer:
x = -6
Step-by-step explanation:
Hello!
2x - 15 = 3(2x + 3)
Distribute the 3
3 * 2x = 6x
3 * 3 = 9
2x - 15 = 6x + 9
Subtract 2x from both sides
-15 = 4x + 9
Subtract 9 from both sides
-24 = 4x
Divide both sides by 4
-6 = x

13. Choose the correct option: If 5 p + 6 = 7, then p = ? 2 a) p = 7 ×2−6 b) p = ( 7−6)×5 c) p = ( 7−6)×2 5 2 5
Answer:
p = (7 - 6)/5Step-by-step explanation:
Given the expression 5 p + 6 = 7, to know the value of variable p. we need to make p the subject of the formula as shown;
Given 5 p + 6 = 7
Step 1: Subtract 6 from both sides
5p+6-6 = 7-6
5p = 7-6
Step 2: We will then divide both sides by the coefficient of p i.e 5 to have;
5p/5 = (7 - 6)/5
p = (7 - 6)/5
Hence, the correct expression of variable p is p = (7 - 6)/5

Given that f(x)=2x+1 and g(x)=-5x+2 slove for f(g(x)) when x=3
Answer:
The answer is - 91
Step-by-step explanation:
f(x)=2x+1
g(x)=-5x+2
To find f(g(3)) first find f(g(x))
To find f(g(x)) multiply f(x) by g(x)
that's
f(g(x)) = (2x + 1)( - 5x + 2)
f(g(x)) = - 10x² + 4x - 5x + 2
f(g(x)) = - 10x² - x + 2
To find f(g(x)) when x = 3 substitute 3 into
f(g(x))
That's
f(g(3)) = -10(3)² - 3 + 2
f(g(3)) = -90 - 3 + 2
We have the final answer as
f(g(3)) = - 91Hope this helps you
What is the value of x
Answer:4,24
Step-by-step explanation:
2(4x+x)=60
10x=60
x=6
4*6=24
Answer:
Step-by-step explanation:
Perimeter of a rectangle = 2 ( l + b ) = 60
here,
l = 4x
b = x
so,
2 ( l + b ) = 60
2 ( 4x + x ) = 60
2 ( 5x ) = 60
5x = 60 / 2
5x = 30
x = 30 / 5
x = 6
so l = 4x = 4 × 6 = 24
b = x = 6
you can also recheck it by
2 ( l + b )
2 ( 24 + 6 )
= 2 × 30
= 60
Which is equal to the perimeter.

Urgent Help. The circle shown above has a radius of 5 units
Area enclosed in [tex] 2\pi[/tex] radians =$\pi r^2$
so area enclosed in $\theta$ radians=$\theta \times \frac{\pi r^2}{2\pi}= \frac{1}2\theta r^2$
does this answer your question?
===================================================
Explanation:
2pi radians is equal to 360 degrees.
The shaded region has a central angle 2pi/5 radians
Divide 2pi/5 over 2pi to end up with 1/5. The "2pi" terms cancel.
The shaded region is 1/5 of the full circle.
The full circle area is pi*r^2 = pi*5^2 = 25pi square units
Taking 1/5 of that leads to (1/5)*25pi = 5pi which is the area of the shaded region.

What is the value of m in the equation 1/2m - 3/4n = 16, when n = 8?
Answer: m= 44
Step-by-step explanation:
1/2m - 3/4n = 16 when n is 8 put it into the equation and solve for m.
1/2m - 3/4(8) = 16
1/2m - 6 = 16
+6 +6
1/2m = 22
m = 44
Answer:
44
Step-by-step explanation:
● (1/2 )× m - (3/4) × n = 16
Replace n by 8 and the fraction by decimal numbers (1/2 = 0.4 and 3/4 =0.75)
● 0.5 × m - 0.75 × 8 = 16
● 0.5m - 6 = 16
Add 6 to both sides
● 0.5 m - 6 + 6 = 16+ 6
● 0.5 m = 22
Multiply both sides by 2
● 0.5m × 2 = 22 × 2
● m = 44

The coordinates of B″ if polygon ABCD rotates 270° counterclockwise to create A″B″C″D″ is at (4, 2)
Step-by-step explanation:
A transformation is the movement of a point from its initial position to a new position. If a shape is transformed, all its points are also transformed. Types of transformation are reflection, rotation, dilation and translation.
Given Polygon ABCD is defined by the points A(-4, 2), B(-2, 4), C(1, 3), and D(2, 2).
If a point X(x, y) is rotated 90° counterclockwise, the new location X' is at (-y, x)

Jason wants to cut a rope that is 60 feet long into several equal pieces with nothing left over. How many pieces will he have if the length of each piece is the greatest integer possible? A)2 B)4 C)6 D)10
Answer:
A
Step-by-step explanation:
In order for the length of the pieces to be as great as possible, the number of pieces must be as small as possible. Jason can't keep the rope in one piece, that doesn't count as cutting the rope into pieces because he hasn't cut the rope. If there were 2 equal pieces, each piece would be 60 / 2 = 30 feet, and since 30 is an integer, the answer is 2.

Answer:
[tex]\boxed{y = 3x - 4}[/tex]
Step-by-step explanation:
Hey there!
Well let's start with slope,
The slope is 3x because the rise is 3 and the run is 1 so the slope is 3x.
Slope = 3
Now the y intercept is -4 because that's where the line touches the y axis.
Equation: y = 3x - 4
