solve each system of equations
5x- 2y = 3
2x + 5y = 7 Ordered pair
Answer:
(1, 1)
Step-by-step explanation:
Solve the System of Equations
5x − 2y = 3
2x + 5y = 7
Solve for x in the first equation.
x = 3/5 + 2y /5
2x + 5y = 7
Replace all occurrences of x with 3/5 +2y /5 in each equation.
Replace all occurrences of x in 2x + 5y = 7 with 3/5 + 2y/5
2 ( (3/5) + (2y/5))+ 5y = 7
x = 3/5 + 2y /5
Simplify 2((3/5)+(2y/5)) +5
6 + 29y = 7 ⋅(5)
x = (3/5)+(2y/5)
Solve for y in the first equation.
Multiply both sides of the equation by 5.
6 + 29y = 7 ⋅ (5)
x = (3/5)+(2y/5)
Remove parentheses.
6 + 29y = 7 ⋅ (5)
x = (3/5)+(2y/5)
Multiply 7 by 5.
6 + 29y = 35
x = (3/5)+(2y/5)
Move all terms not containing y to the right side of the equation.
Subtract 6 from both sides of the equation.
29y = 35 − 6
x = (3/5)+(2y/5)
Subtract 6 from 35.
29y = 29
x = (3/5)+(2y/5)
Divide each term by 29 and simplify.
Divide each term in 29y = 29 by 29.
29y/29 = 29/29
x = (3/5)+(2y/5)
Cancel the common factor of 29.
y = 29 /29
x = (3/5)+(2y/5)
Divide 29 by 29.
y = 1
x = (3/5)+(2y/5)
Replace all occurrences of y with 1 in each equation.
Replace all occurrences of y in x = (3/5)+(2y/5) with 1.
x = (3/5)+(2(1)/5)3
y = 1
Simplify
x = (3/5)+(2(1)/5)3
y = 1
x = 1
y = 1
The solution to the system is the complete set of ordered pairs that are valid solutions.
(1, 1)
The result can be shown in multiple forms.
Point Form:
(1, 1)
Equation Form:
x = 1, y = 1
Answer:
(1, 1)
Step-by-step explanation:
We can solve each system of equations by using the elimination method for the first variable and then substituting for the second variable.
To eliminate, we must make one the same by multiplying the equation by a constant. Let's make x the same by multiplying the first equation with 2 and the second equation with 5. Both should get 10x.
10x - 4y = 6
10x + 25y = 35
Now we can eliminate x by subtracting these equations (this works since 10x - 10x = 0). So:
-4y - 25y = 6 - 35
-29y = -29
y = 1
Now that we have y, we can substitute it into either equation and solve for x.
5x - 2(1) = 3
5x = 5
x = 1

The Ladybugs have a 30cm by 10cm rectangle for pumpkins. Each pumpkin needs exactly 25 square centimeters of space. How many pumpkins can they plant?
Answer:
They can plant 12 pumpkins.
Step-by-step explanation:
First we calculate the area of the rectangle for pumpkins:
Area = side * side
Area = 30 cm * 10 cm
Area = 300 cm²
Then we divide that area by the space required by one pumpkin, to calculate how many pumpkins they can plant:
300 cm² / 25 cm² = 12
So the Ladybugs can plant 12 pumpkins.

We have: I = P × R × T / 100
Here, I = 980
P = 7000
T = 8
Substitute their values into the expression:
980 = 7000 × R × 8 / 100
R = 980 × 100 / 7000 × 8
R = 98000 / 56000
R = 1.75%
In short, Your Answer would be 1.75%

Figure ABCD is similar to figure WXYZ
Answer:
1. ∠A = ∠W
2. ∠B = ∠X
3. ∠C = ∠Y
4. ∠D = ∠Z
Step-by-step explanation:
This is actually a lot more simple than you think!
In order to solve this you must be able to distinguish both of the points from each figure shown in the picture!
In this case, we can see that Figure WXYZ is faced in a upright manner!
While Figure ABCD is in a regular position!
What you want to do is turn either Figure ABCD or WXYZ in to the same position and you will see that the shape, points, and position will be same!
For example:
(This is two separate lines that are in different positions)
A
|
B
C ------ D
If you are to change either in the same position, in this case I'll change
line AB to the same position as CD:
A ------ B
C ------ D
You can see that which points will be corresponding to each other!
(Corresponding means two that are similar or same to each other in characteristics)
So the answer to the example would be:
Point A = Point C
&
Point B = Point D
Back to the original problem, it works the same way:
If you turn figure WXYZ in the same position as ABCD, you will get the answers:
1. ∠A = ∠W (Answer choice: B)
2 ∠B = ∠X (Answer choice: C)
3. ∠C = ∠Y (Answer choice: D)
4. ∠D = ∠Z (Answer choice: A)
You can also see this when they say:
'Figure ABCD is similar to Figure WXYZ'
In means of angles it would look like:
(Figure) ABCD = (Figure) WXYZ
And if you were to separate each letter with the one it corresponds to on the other side, you will see that you will get:
A = W
B = X
C = Y
D = Z

Which letter has rotational symmetry? I, J, K, L?
The letter I has rotational symmetry from the given letters I, J, K and L.
Rotational symmetry refers to the property of an object that remains unchanged or looks the same after being rotated by a certain angle around a fixed point.
The letter "I" has rotational symmetry because it looks the same when rotated by 180 degrees (half a turn) around its center.
So the letter I has rotational symmetry.

x intercept =
Answer:
x = -15
y = -10
Step-by-step explanation:
To find the x intercept, we have to substitute 0 into y
4x + 6(0) + 60 = 0
4x + 0 + 60 = 0
4x + 60 = 0
4x = -60
x = -15
To find the y intercept, we have to subsitute 0 into x
4(0) + 6y + 60 = 0
6y + 60 = 0
6y = -60
y = -10
