Answer:
Therefore the required resulting equation is
![6x-15y=-63\\-15x+15y=90](https://tex.z-dn.net/?f=6x-15y%3D-63%5C%5C-15x%2B15y%3D90)
6 x minus 15 y = negative 63.
Negative 15 x + 15 y = 90
Step-by-step explanation:
Given:
......................Equation ( 1 )
......................Equation ( 2 )
To Find:
Expression after multiplying to eliminate y term,
Solution:
So to eliminate 'y' term we need to multiply equation 1 by a constant 3 and equation 2 by a constant -5, such that equations becomes
.....( 1 )
.....( 2 )
so now by adding new equation one and two we can eliminate y term that means -15y and +15y will get cancel,
Therefore the required resulting equation is
![6x-15y=-63\\-15x+15y=90](https://tex.z-dn.net/?f=6x-15y%3D-63%5C%5C-15x%2B15y%3D90)
6 x minus 15 y = negative 63.
Negative 15 x + 15 y = 90
Answer:
x>8
Step-by-step explanation:
4+3x>24
-4 -4
3x > 24
/3 /3
x > 8
Answer:
0.4 is left in the box
Step-by-step explanation:
1.00 = jumbo box of cereal
1.00-60%= 1-0.6=0.4
Set up a proportion:
3/4/24 = 1/x
Cross multiply:
3/4x = 24
Divide 3/4 to both sides or multiply by its reciprocal, 4/3:
x = 24 * 4/3
x = 96/3
x = 32
So you had a total of 32 muffins, now subtract this from the amount that blew away to find out how many you have left:
32 - 24 = 8
So you have 8 muffins left.
Answer:
143 square meters
Step-by-step explanation:
The surface has a width of 11 meters and a length of 13 meters.
