Answer: Create equations. Top length=Bottom length
Left side = right side.
Combine like terms and rewrite the equations.
Use the new equations to create a system of equations to solve for x and y.
Once you have x and y, you can substitute those in the expressions for the lengths of the parallelogram.
You should end up with top and bottom lengths of 10. The sides are 9.
Step-by-step explanation:
3x-5 = 18 -2y . Rewrite as 3x + 2y = 23
x+4 = 21 -3y Rewrite as x + 3y = 17
The system of equations is
3x + 2y = 23 and x + 3y = 17 . To solve by substitution, multiply the second equation by -3 It becomes -3x-9y= -51 Add the equations so the x terms cancel. Solve for y
3x + 2y = 23
-3x - 9y = -51
0 -7y = - 28 Divide both sides by -7. y = 4
Substitute 4 for y, solve for x
x + 3(4) = 17
x + 12 = 17 . Subtract 12 from both sides x = 5
Substitute the values of x and y in the expressions
Top: 3x-5 is 3(5) -5 becomes 10
Bottom: 18 -2y is 18 - 2(4) becomes 10
Left: x +4 is (5) + 4 becomes 9
Right: 21 - 3y is 12 -3(4) becomes 9

What is the intercept in the equation?In the equation intercept is the value of the linear function where either of the variables is zero.
Here,
To find the x-intercept, we need to find the point at which the graph intersects the x-axis. This occurs when the y-coordinate is zero.
The x-intercept is therefore (7, 0).

The sum of two numbers is 44 and the difference is 2 What are the numbers
Answers
Answer:
21 & 23
Step-by-step explanation:
44 ÷ 2 = 22
The two numbers are going to be close to 22.
21 + 23 = 44
32 - 21 = 2
Answer:
You can try to write two equation from the question
Call x a number and y the other.
The sum of them is 44: x + y = 44
The difference (substract) is 2: x - y = 2
System:
x+y=44
x-y = 2
You can just sum both equations, as the y disappear:
2x = 46
x =46/ 2 = 23
We replace in the equation:
23 - y = 2
y = 21
And we know the numbers are 21 and 23
9x - 4y= 19
4x + 4y= 20
Answers
Answer:
x=3 and y=2
Step-by-step explanation:
9x - 4y= 19
4x + 4y= 20
add both equations;
13x = 39
x= 3
using 4x + 4y= 20;
4(3) +4y=20
12+4y=20
4y= 20-12=8
y=8/4=2

Step-by-step explanation:

Hii!
__________________________________________________________
Answer:
3(x-10)
Step-by-step explanation:
Note that both terms, 3x and -30, have a 3 in common. This is called the greatest common factor, or g.c.f.
The g.c.f. of 3x and -30 is 3. So we divide both 3x and -30 by 3, and obtain
x-10
Put parentheses around x-10
(x-10)
Next, put 3 outside the parentheses
3(x-10)

Answers
Answer:
x=5
From the dashed lines on the two sides of this triangle, we can see that these two sides are congruent, or equal, to each other.
In geometry, if a triangle has two congruent sides, then we can call it a isosceles triangle.
In an isosceles triangle, the corners opposite the congruent sides are also congruent, meaning, that the angle measures of this triangle are: 88, 9x+1, and 9x+1.
We also know that angles in a triangle add up to 180 degrees.
So, we have: 88+(9x+1)+(9x+1) = 180
Simplifying: 18x + 2 = 92
Solving: 18x = 90, so x=5
