Answer:
102.85
Step-by-step explanation:
87% of 55=47.85
55+47.85=102.85
Answer:
240 units I think
Step-by-step explanation
20 by 2 equal 10 you now know the triangle length
then 4 X 10 equal 40 by 2 equal 20 by 2 equal 40. area of both triangles
20 X 10 equal 200 length of rectangle add both and equal 240.
The bike is now $28
(70 x 0.4 = 28)
Answer:
If each piece is 1 yard long then 16 /1=16 so she can cut 16 pieces
Step-by-step explanation:
The xy-value in the solution to the given system of linear equation shows that x = 2 and y = -4.
<h3>What is a system of linear equations?</h3>
Whenever two or more linear equations operate simultaneously, we create a System of Linear Equations. These equations must contain one or more similar variables in order to operate together.
When solving a system of linear equations, our objective is to simplify two equations having two variables to a single equation having one variable. Because each equation in the system includes two variables, substituting an expression for a variable is one technique to minimize the number of variables in an equation.
From the given information:
4x + 5y = -12 --- (1)
-2x + 3y = -16 ----- (2)
From equation (1)
4x+5y+(−5y) = −12 + (−5y) (Add -5y to both sides)
4x = −5y − 12
Divide both sides by 4


Replacing the value of x in
into equation (2); we have:


Simplifying both sides of the equation, we have:


Cross multiply
11y = -44
y = -4
Replace the value of y = -4 into 

x = 2
