A system of equation is shown.
5x+2y=245
y=x+6
Enter a numeric value to complete the solution of the system.
Answer:
y = 245 / 7, x = 29
Step-by-step explanation:
make both into ax + by = c format which is
Math:
5x + 2y = 245
-5x + 5y = 30 <== 5 (- x + y = 6) to cancel out the x since it has a negative already.
[(Side Note) if both were positive then you would need to do
EX: - 5 (- x + y = 6)]
Continued:
7y = 275 ==> 7y/7 = 245/7
y = 245 / 7
Plug it in the most convenient one which has the equation y = x + 6
and tweak it a bit
x = y - 6
x = 245 / 7 - 6 ==> 245 / 7 - 42 / 7
x = 203 / 7 ==> 29

[tex]9^{x}[/tex] = 9 (With x as 1) [tex]3^{x}[/tex] = 3 (With x as 1) [tex]x^{3}[/tex] = 1 (With x as 1)Step-by-step explanation:
With x = 1, we can substitute the value 'x' as the exponent. Answers are below.
=> [tex]9^{x}[/tex] = [tex]9^{1}[/tex] = 9=> [tex]3^{x}[/tex] = [tex]3^{1}[/tex] = 3=> [tex]x^{3}[/tex] = [tex]1^{3}[/tex] = 1Please answer all of them i need this ASAP

A car factory had an inventory of 327 car radios in stock. Then the company installed a radio in each of 243 cars and delivered those cars. Write and then evaluate an addition expression for the remaining inventory of radios.
Enter the correct answers in the boxes.
Answer:
Equation: 243+x=327
Answer to the equation: x=84
Step-by-step explanation:
First, subtract 243 from both sides of the equation, which would leave you with x=84, which is your answer.

HELP PLZ ND THX U?!?!?!?!?!?!?!?!?!
Answer:
U = 1
Answer = 6
Step-by-step explanation:
We can do really any number. But in this case, we are gonna do 1. So, it would look like (7 x 1) - 1. It would look like that because we know that 7u is equal to 7 times U or in this case, 7 times 1. So, we know 7 x 1 is 7. Now, we do 7 - 1 since U = 1, and we get our answer of 6.
Please answer the picture
Answer:
B. not equivalent

Last week, Byron bought 5 containers of yogurt and spent $12.88 on other groceries.
This week Cassandra bought 3 containers of the same yogurt and spent $11.50 on other
groceries. How much more money did Byron spend than Cassadra.
1. Let c represent the cost of one container of yogurt. Write
expressions to represent the amount spent by Byron and the
amount spent by Cassandra.
2. Write an expression to represent the difference by subtracting theamount that Cassandra spent from the amount that Byron spent.
Then complete the steps to simplify the expression
3. What expression represents how much more money Byron spent
than Cassandra?
Will Mark Brainlest
Answer: 5c$12.88 - 3c$11.50=C
Step-by step explanation:
Byron=5c + $12.88
Cassandra=3c + $11.50
So then, 5c$12.88 - 3c$11.50=C

A bank pays 7% interest on 3-year certificates of deposit. What is the value of a $500 certificate after one year? Give your answer to the nearest cent.
The value after one year will be $535.
What is interest?Interest, in its most simple form, is calculated as a percent of the principal. For example, if you borrowed $100 from a friend and agree to repay it with 5% interest, then the amount of interest you would pay would just be 5% of 100: $100(0.05) = $5.
Interest is most often reflected as an annual percentage of the amount of a loan. This percentage is known as the interest rate on the loan. For example, a bank will pay you interest when you deposit your money in a high-yield savings account.
given:
amount= $500
interest rate = 7% on 3-year certificates of deposit.
So, after one year the value will be
=500 x 7% + 500
=500 x 0.07 + 500
= 35 + 500
= $535
Hence, the value will be $535.

Describe in detail how you would create a number line with the following points: 4, 1.25, the opposite of 3, and – (–2fraction of one-half). Please be sure to describe on which tick marks each point is plotted and how many tick marks are between each integer. It may help for you to draw this number line by hand on a sheet of paper first. brainleist for right answere if u dont answer propoly i will report!
Answer:
Given : points 4 , 1 ,25 , opposite of 3 , -1/2
To Find : draw on Number Line
Solution :
Numbers with a negative sign are less than zero
Right of zero represented by ‘+’ sign and to the left of zero represented by ‘–’ sign.
+ sign numbers can be denoted as simply numbers
On a number line the number increases as we move to the right and decreases as we move to the left.
1 : Draw a line and mark some points at equal distance on it as shown in the figure below Mark a point as zero on it. Points to the right of zero are positive integers and are marked simply 1, 2, 3 and so on , while points to the left of zero are negative integers and are marked – 1, – 2, – 3 and so on
2. Go 4 unit on right sides from Zero to show 4
3. Go 3 units on Left from zero to show opposite of 3
4. Divide number line between 1 & 2 in 4 Equal parts and go 1 part right of 1
5. Divide number line between 0 & -1 in 2 Equal parts and go 1 part left of 0

Define a variable, set up an equation, then solve.
Sean and Evan are selling rolls of wrappign paper to raise money for new football uniforms. Evan has sold seven more than one-half the number of rolls that Sean has. If they have sold a total of 121 rolls, how many has Evan sold?
x - Rolls sold by Evan
Let x be the number of rolls sold by Sean.
We are given that Evan has sold 7 more that one-half the number of rolls that Sean sold.
Evan has sold 1/2x + 7 rolls.
Therefore, we have:
x + (0.5x + 7) = 121
1.5x = 121 - 7
x = 114/1.5
x = 76

Step-by-step explanation:
Given the graph of a negative-sloped function:
In order to determine the value of a function given that x = 2, simply locate the x-coordinate of 2 in the graph, and find its corresponding y-coodinate. Doing so will provide you the corresponding output value of y = -3. Therefore, the value of the function at x = 2 is f(x) = -3, or f(2) = -3.

3x + 5y + 10
5x - 3y = -6
Answer:
3x + 5y + 10= 3
5x - 3y = -6
Step-by-step explanation:
1. m=-3/5
2. Simplifying
5x + -3y = 6
Solving
5x + -3y = 6
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3y' to each side of the equation.
5x + -3y + 3y = 6 + 3y
Combine like terms: -3y + 3y = 0
5x + 0 = 6 + 3y
5x = 6 + 3y
Divide each side by '5'.
x = 1.2 + 0.6y
Simplifying
x = 1.2 + 0.6y

Answer:
2. yes; the equation can be written as y = kx; k = 1
Step-by-step explanation:
x-y = 0
That means x and y have to be the same value.
If you multiply a number by 1, you get the same thing.
If you multiply x by one, you get y (the same value).
