Answer:
Step-by-step explanation:
To solve the system using elimination, first multiply the bottom equation by 2. Write the new system of equations. (1 point)
5x + 2y = 7
6x –2y = 4
Why is this multiplication allowed? (1 point)
Because the entire equation was multiplied by the same number, the equation remains the same.
What variable will be eliminated when the equations are combined after the multiplication? (1 point)
The Y variable
Next, add the equations together. Your answer should be a single equation with one variable. (1 point)
11x = 11
Solve the equation for x. (1 point)
X = 1
What is the solution to the system of equations? (1 point)
X = 1 and Y = 1 so the answer is (1, 1)
(If you solve this again, but eliminate the X variable, you will still receive that answer 1, so Y = 1)

A right triangle has sides of length 3, 4, and x. Find x if it is one of the legs.
HELP ON THIS ONE????
Answer:
C) 2.6
Work Shown:
a = x, b = 3, c = 4
a^2 + b^2 = c^2 ... pythagorean theorem
x^2 + (3)^2 = (4)^2
x^2 + 9 = 16
x^2 = 16 - 9
x^2 = 7
x = sqrt(7)
x = 2.64575131106459
x = 2.6

The expression that represents the number of tulips Pia planted is option A. x/2 + 4.
What are Expressions?Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.
Given that,
Number of daisies planted is represented by x.
Number of tulips planted is 4 more than half the number of daisies.
Half the number of daisies is x/2.
4 more than half the number of daisies is x/2 + 4.
Hence the number of tulips planted is given by the expression x/2 + 4.

The original price is $70.00
The problem states that $59.50 is the discounted price, this means that it is not the 100% price of the aquarium. Since 15% is the discount, the remaining price is equivalent to 85% of the original price, which amount to $59.50.
100% - 15% = 85%
100% - 15% = $59.50
To get original price, we must divide the discounted price by its corresponding percentage.
$59.50 / 85% = original price
$59.50 / 0.85 = $70
To check, we must get the 15% equivalent amount from the original price.
$70 x 15% = $10.50 discount value
$70 - $10.50 = $59.50 discounted price

Answer:
x y
4/3 2
8/3 10/3
22/3 24/3
Step-by-step explanation:
Substitute y with 2 for the first problem
2=x+2/3
Subtract 2/3 on both sides:
4/3
Thus:
x y
4/3 2
Now Substitute x with 8/3 for the second problem
y=8/3+2/3
Add:
y=10/3
Thus:
x y
8/3 10/3
Now Substitute x with 8/3 for the third problem
y=22/3+2/3
Add:
y=24/3
Thus:
x y
22/3 24/3
Thus the Full equation is:
x y
4/3 2
8/3 10/3
22/3 24/3
Hope this helps!
Answer:
x y
4/3 2
8/3 10/3
22/3 8
Step-by-step explanation:
y=x+2/3
2=x+2/3
2-2/3=x+2/3-2/3
6/3-2/3=x
4/3=x
y=x+2/3
y=8/3+2/3
y=10/3
y=x+2/3
y=22/3+2/3
y=24/3

Answer:
-1/2x-2
Step-by-step explanation:
Distribute the negative sign from the right side to make the equation positive
1/4x - 7 + (-1)(3/4x) + (-1)(-5)
(basically multiplying -1 to 3/4x and -5 to eliminate it)
1/4x - 7 + -3/4x+ 5
Make the equation similar
(1/4x + -3/4x) + (-7 + 5)
combine like terms
1/4x + -3/4x = -2/4x --> Simplifies to -1/2x
Do the other integers
-7 + 5 = -2
Put it together
-1/2x-2
