Answer:
The solution to the system of equations be:
Step-by-step explanation:
Given the system of equations
Let us solve the system by the elimination method
Arrange equation variables for elimination
subtracting the equations
so the system of equations becomes
solve 5x for x
Divide both sides by 5
Add 6 to both sides
Therefore, the solution to the system of equations be:
Answer:
◻️B. The value of the mode is the least value of the data.
Step-by-step explanation:
The mode is the data value that appears most often
5,7,9,5,18,6,8,5
Arranging the data from smallest to largest
5,5,5,6,7,8,9,18
The number that appears most often is 5
This is the smallest value of the data
Capacity = volume
capacity = 420 cm3

Answer:
B) 10x + 8y ≥ 210
Step-by-step explanation:
We know that we have to sit at least 210 people which means that we can fit more than 210, but no less than 210. This gives us a first step in solving since we know that the equation must be greater than or equal ( ≥) 210
This rules out C & D immediately.
Now we know that circular tables can sit 10 people and are represented by the variable x which means that each circular table will be equal to 10x and that rectangular tables are denoted by y and can sit 8 people making it recognizable by 8y. We know that the people sitting at all of the tables will be added up to give us a number of either 210 or more.
The only answer that gives us the tables and how many people they seat accurately is B since it is 10x and 8y. We also see that these two numbers are added together to make it greater than or equal to 210.
Answer:
x=10 x=-2
Step-by-step explanation:
(x − 3)(x − 5) = 35
FOIL
x^2 -5x-3x+15 = 35
Combine like terms
x^2 -8x+15 = 35
Subtract 35 from each side
x^2 -8x+15-35 = 35-35
x^2 -8x-20 =0
Factor
What 2 numbers multiply to -20 and add to -8
-10*2 = -20
-10 +2 = -8
(x-10)(x+2) =0
Using the zero product property
x-10 =0 x+2 = 0
x=10 x=-2
