Answer:
C
Step-by-step explanation:
x + y = 2
Subtract x from both sides;
y = -x + 2
3x - 4y = 27
Substitute y;
3x - 4(-x + 2) = 27
Distribute;
3x + 4x - 8 = 27
7x - 8 = 27
Add 8 to both sides;
7x = 35
Divide both sides by 7;
x = 5

What is Equivalent?
Is it possible for two things to look different but be equal
to one another? Think about $10... is a $10 bill the only
way you can have $10? Give an example of money that
is equivalent to a $10 bill.
Answer:
Equivalent is when two things contain the same total value. For example, you could give two 5 dollar bills instead of one 10 dollar bill and they would be equivalent as they would both total to be 10 dollars.
Step-by-step explanation:
$10 = 2 * x
$10/2 = $5
x = $5

For a science experiment, Marcia dissolved 1.0 kilogram of salt in 3.0 liters of water. For a different experiment, Bobby dissolved 2.0 pounds of salt in 7.0 pints of water. Which person made a more concentrated salt solution? Explain. Use 1 L = 2.11 pints. Round your answer to the nearest hundredth.
Step-by-step explanation:
The concentration of Marcia's solution is:
1.0 kg / 3.0 L = 0.33 kg/L
The concentration of Bobby's solution is:
(2.0 lb × 1 kg / 2.2 lb) / (7.0 pints × 1 L / 2.11 pints) = 0.27 kg/L
Therefore, Marcia's solution is more concentrated.

L 1. Andrew's hobby is mountaineering. He
started his hike at 250 feet above sea level.
When he reached the peak of the mountain
he was at 1700 feet above sea level. How
many feet did Jake hike up the mountain?
Answer:1700
Step-by-step explanation:
In total, he traveled 1700 feet. He had to get to the 250ft starting point somehow, so you would count that as the overall total distance traveled.

Additive Identity Property: The sum of any number and zero is the original number. For example 5 + 0 = 5.
Which letter represents the first number in an ordered pair?
Step-by-step explanation:
Example: (5,2)
On a graph, the 5 goes on the x-axis and the 2 goes on the y-axis.
Also, in the world of variables, and the alphabet, x is before y.
So x represents the first number in an ordered pair.

Which expression is equivalent to 3.7 x + (0.5-6y)+0.8-(1.7x+1-2.3y)?
Answer:
2.0x-8.3y+2.3Step-by-step explanation:
Give the expression 3.7 x + (0.5-6y)+0.8-(1.7x+1-2.3y), to get the equivalent expression we will follow thw steps;
open the parenthesis
3.7 x + 0.5-6y+0.8-1.7x+1-2.3y
collect like terms
= 3.7 x -1.7x -6y-2.3y+0.5+0.8+1
= 2.0x-8.3y+1.3+1
= 2.0x-8.3y+2.3
Hence the equivalent expression is 2.0x-8.3y+2.3

2 times the square root of 25 plus the square root of negative 16
Answer:
10 + 4 i
fnjeob cbjkocbhv bjwokjnb jnokemnef
Answer:
10+4i
Step-by-step explanation:
2*√25 + √-16.
Given
2*5+4i
Simplify the sqrts. If you are wondering where I got "i" from, "i" is √-1. "i" is short for imaginary number because there is no real number that can be a square root of a negative number. I got the 4 because it is the square root of -16
10+4i
I multiplied the 2 and the 5. This is the simplest form because you cannot add imaginary and real numbers together.
I need someone to explain functions and functional symmetry to me. This is very important, so if you do not have a legit answer, you will get reported.
Symmetrical functions can be about the x and y axis. Essentially, if we reflect the graph across the y or x axis, we get the same graph. Some other graphs can be reflected across both the x and y axis at the same time and be symmetrical. These can be classified as odd and even functions. You can test this by replacing x and y with -x and -y and simplify the equation. If the results comes out to be the same as the original, it is symmetrical across the origin.
Best of Luck!
Answer:
a shape that has reflective symmetry either x or y axis of origin.
in other words... it's a mirror image.
