true or false, to be a solution to a system of equations, the solution must satisfy all of the equations in the system.
Answer:
True
Step-by-step explanation:
Answer: To find the unique solution to a system of linear equations, we must find a numerical value for each variable in the system that will satisfy all of the system's equations at the same time. ... Both of these statements are true, so (4,7) is indeed a solution to the system of equations.

The cost of renting a bowling alley for a party is $110, plus $5 a person for food. Which equation can be used to find the total cost, C, of a party at a bowling alley for x friends?
Answer:
c=110+5x
Step-by-step explanation:
The equation that represents the total cost is C = 5x + 110.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
The expense of leasing a bowling alley for a party is $110, in addition to $5 an individual for food.
Let 'C' be the total cost and 'x' be the number of friends. Then the equation is written as,
C = 5x + 110
The equation that represents the total cost is C = 5x + 110.

Answer:
As
parts per million can be calculated by applying formula Ppm=(mass of solute/mass of solution)×1,000,000
In given condition
Mass of solute which is NaCl is 284g
Mass of solution which is watervis 100g
Ppm=284/100×1,000,000
=284000ppm

Find the value of 2. 128° xº 820 40° to E
Please help me
Answer:
110 degrees
Step-by-step explanation:
Ok so in a quadrilateral, the sum of the interior angles have to add up to 360 degrees*.
This means that x + 128 + 82 + 40 = 360, so you can solve this as an equation:
x + 128 + 82 + 40 = 360
x + 250 = 360
x = 110 degrees
*The reason the interior angles of a quadrilateral add up to 360 degrees is because the formula for the sum of the interior angles in a polygon is
180 * (n - 2) where n is the number of sides, so since this polygon has 4 sides it would be:
180 * (4 - 2)
180 * 2
360 degrees
Hope that makes sense!

How do I find x in this question?
Answer:
x = 8
Step-by-step explanation:
By Basic Proportionality Theorem:
[tex] \frac{3}{x - 2} = \frac{x}{x + 8} \\ \\ x(x - 2) = 3(x + 8) \\ \\ {x}^{2} - 2x = 3x + 24 \\ \\ {x}^{2} - 2x - 3x - 24 = 0 \\ \\ {x}^{2} - 5x - 24 = 0 \\ \\ {x}^{2} - 8x + 3x - 24 = 0 \\ \\ x (x - 8) + 3(x - 8) = 0 \\ \\ (x - 8)(x + 3) = 0 \\ \\ x - 8 = 0 \: \: or \: \: x + 3 = 0 \\ \\ x = 8 \: \: or \: \: x = - 3 \\ \\ \because \: length \: can \: not \: be \: - ve \\ \\ \implies \: x \neq - 3 \\ \\ \implies \: x = 8[/tex]
