Answer:
(x, y) = (4, 1)
Step-by-step explanation:
Step 1. Look for an equation that has a coefficient of 1 or -1 for one of the variables. Here, that is the first equation, which has a y-coefficient of -1.
Step 2. If you found such an equation, solve for the variable.
y = 2x -7
Step 3. Use that expression for the variable to substitute into the other equation.
3x -2(2x -7) = 10
Step 4. Solve the resulting equation in the usual way.
3x -4x +14 = 10 . . . . . eliminate parentheses
-x +14 = 10 . . . . . . . collect terms
4 = x . . . . . . . . . separate variable terms and constant terms. Here, we added x-10 to both sides.
If the variable has a coefficient that is not 1, divide both sides by that coefficient.
Now, you can use this value in the expression for y that we found above.
y = 2(4) -7 = 1
The solution is (x, y) = (4, 1).

Answer:
The sector for 126 rubies would measure 126 degrees.
Step-by-step explanation:
First, a pie-chart is a circle, and there are 360 degrees in a circle. Because there are 320 total gemstones, 1 gemstone maps to 1.125 degrees. That is, 1.125 degrees per gemstone.
[tex]360\div320=1.125[/tex]
Knowing that, you can calculate the degrees in the pie-chart for any given number of gemstones. Just multiply the gemstones by 1.125.
[tex]112\times1.125=126[/tex]
The sector for 112 rubies would measure 126 degrees.
If you want to be extra sure, you can calculate that for all types of gemstones and add them up:
[tex]32\times1.125=36\\112\times1.125=126\\96\times1.125=108\\64\times1.125=72\\16\times1.125=18\\36+126+108+72+18=360[/tex]
That confirms they all add up to 360 degrees.

y = x -4
y = -x + 6
What is the solution for this system of equations?
(1,5)
(6, – 4)
(-4, 6)
(5, 1)
Step-by-step explanation:
y = x - 4
y = -x + 6
x - 4 = -x + 6
x + x = 6 + 4
2x = 10
x = 10/2 = 5
y = x - 4
y = 5 - 4
y = 1
Solution = (5,1)

Stephen can deliver 16 newspapers in 20 minutes. How long will it take him to deliver 64 papers? How long will it take to deliver 140 papers? How many papers can you deliver in 195 minutes?
Answer/Step-by-step explanation:
Given:
16 newspapers in 20 minutes
To Find:
How long will it take him to deliver 64 papers?
How long will it take to deliver 140 papers?
How many papers can you deliver in 195 minutes?
Note:
First Find deliver for newspaper in 1 minutes..
20/16=1.25
16/20=0.8
Solution:
How long will it take him to deliver 64 papers?
1.25x64=80
Therefore, 80 minutes to deliver 64 papers.
How long will it take to deliver 140 papers?
1.25x140= 175
Therefore, 175 minutes to deliver 140 papers.
How many papers can you deliver in 195 minutes?
0.8x195=156
Therefore, 156 papers is deliver in 195 minutes.

One moving company charges 100$ plus 10$ per hour. Another company charges $50 plus $15 per hour. At what number of hours will the charge by both companies be the same?
The answer is ten hours because 10*10=100+100=200 so if 15*10=150+50=200 they are the same so the answer is 10 hours

what is the answer to 5a+3b=c
Answer:
a = -0.6b + 0.2c
Step-by-step explanation:
Simplifying
5a + 3b = c
Solving
5a + 3b = c
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-3b' to each side of the equation.
5a + 3b + -3b = -3b + c
Combine like terms: 3b + -3b = 0
5a + 0 = -3b + c
5a = -3b + c
Divide each side by '5'.
a = -0.6b + 0.2c

the diagonals of a rhombus are 16 cm and 12cm. find its length
Answer:
l=10 cm
Step-by-step explanation:
In a rhombus, the diagonals are cut into identical lines at the intersection.
This way, I found the measures of the halves of the diagonals in a right triangle, knowing that the diagonals of the rhombus are perpendicular on each other.
I calculated that AO = AC/2= 8, and that BO=BD/2= 6, and then I applied pytagora's theorem in a quarter of the rhombus, which is the right triangle AOB, to find the length of a side

what are the zeros of the polynomial function ? f(x) = 2x (x-2) (1-x)
Answer:
The zeros are 0 ,2, and 1
Step-by-step explanation:
f (x) = 2x (x - 2) (1 - x)
set f(x) equal to y
y = 2x (x - 2) (1 - x)
solve when y is 0 because when y is 0 then it is an x-intercept
0 = 2x (x - 2) (1 - x)
separate all of the equations out
0 = 2x
0 = (x - 2)
0 = (1 - x)
solve for x for each equation
0 = 2x
divide both sides by 20/2 = 0 and 2x/2 = x0 = xx = 00 = (x - 2)
add 2 to both sides0 + 2 = 2 and (x - 2) + 2 = x2 = xx = 20 = (1 - x)
subtract 1 from both sides0 - 1 = -1 and (1 - x) - 1 = -x-1 = - xmultiply both sides by -1-1 · -1 = 1 and -x · -1 = x1 = xx = 1
Ann works as a tutor for $9 an hour and as a waitress for $8 an hour. This month, she worked a combined total of 94 hours at her two jobs.
Lett be the number of hours Ann worked as a tutor this month. Write an expression for the combined total dollar amount she earned this month.
Answer:
Ann earned $752+x in a month
If you take t as hours he worked as tutor then ,
Money earned will be $752+t
Answer:
earnings = 752 +t
Step-by-step explanation:
If Ann worked t hours as a tutor, then she worked (94-t) hours as a waitress. Her total wages were ...
earnings = waitress wages + tutor wages
earnings = 8(94 -t) + 9(t)
earnings = 752 +t . . . . . . . simplify

Write a function that represents the relationship between X and y shown in the graph below
Answer:
y = 3x - 10
Step-by-step explanation:
Find the slope of the line by calculating the Rise/Run between any two points. I picked (-2,-16) and (4,2).
The Rise is = (2-(-16))=18
The Run is = (4 -(-2)) = 6
Rise/Run is 18/6 = 3. The slope is three:
y = 3x + b
b is the y-intercept, the value of y when x=0. b is - 10 in this graph.
y = 3x - 10 is the line of this graph.
as the x value increases, the y values stay the same.
