Answer:
multiply one equation through by a constant value that will cause one of the variables to have the same coefficient
Step-by-step explanation:
Multiply the first equation by 3, Next, add the two equations, which means add like terms, and lastly pick either of the original equations and substitute in y
Answer:
The new organic coffee should be sold at grocery stores.
Average no. of locations chosen by per potential customer is 1.5 .
Step-by-step explanation:
As most of the customers (the no. is 20 from the data) voted for selling the new organic coffee at the grocery stores so, the product should be sold at grocery stores.
Total no. of locations chosen,
= (20 + 16 + 14 + 10)
= 60
Total no. of potential customers = 40
so, average no. of locations chosen per potential customer,
=
= 1.5
Answer:
x < -8
Step-by-step explanation:
3 - (2x - 5) < -4(x + 2)
3 - 2x + 5 < -4*x -4*2
-2x + 8 < -4x - 8
-2x + 4x < -8 -8
2x < -16
x < -16/2
x < -8
Answer:
B
Step-by-step explanation:
When solving equations, you need to isolate the variable on one side of the equal sign with the constants on the other. In order to do this, it is required to rearrange the equation using inverse operations. These operations can be done using the properties like addition property of equality, subtraction property of equality and multiplication property of equality. Each property states that the operation does not change the equality of the situation. This means both sides of the equation sign remain equal. Use the property when most to your advantage.
4x-28=2x-6 needs the variable x isolated. The best first move is to rearrange the constants by adding 28 to both sides. This is allowed by the addition property of equality.
Answer:
x+2=5
x+3=6
x^2 + 3x + 2 = 0
