can someone help me with these questions?
Answer:
1. 2:5
2. 110 (the total degree of a triangle is 180 so it would be 40+30+x=180)
3. 37 (It's a right angle, 90 degrees so it would be 90-53=x)
solve the system of linear equations by graphing y=x-1 and y=-x+3
Is this what u wanted?

Im trying to do IXL and I dont understand the way my teacher teaches (ironic right?)
Can you please help?
the points (-9,-3) and (-2,r) fall on a line with a slope of 1/7. What is the value of r?
If its not right im gonna report you
Answer:
R = -2
Step-by-step explanation
-9, -3 is the first point.
A slope of 1/7 means that for every one unit that "rises" it will have a "run" of 7 units.
-9 - 7 = -2
-3 - 1 = -2 (r)
with a slope of 1/7, (-9, -3) connects to (-2, -2)

Please help me with this! Also, if you can, what are prime numbers? I need to understand! 0-0
Answer:
9
Step-by-step explanation:
So a prime number is any number that can only be divided by 1 and itself. 7, 3, and 13 are all prime numbers.
Hope i could help you
Answer: 9
Step-by-step explanation:
a prime number is a number which has factors as one and itself.
All the numbers when multipled by 1 give the same number and no other two numbers hanging multiply it.
But for 9,1*9 gives 9 and 3*3 gives 9

Use a system of equations to find two numbers with a difference of 2 and a sum of -8. Show your work.
Answer:
-3 & -5
Step-by-step explanation:
let the two numbers be x and y
x + y = -8. sum of the numbers is -8
x - y = 2. difference(-) of the numbers is 2
now we add the two equations
x + x + y - y= -8 + 2
2x = -6
x = -6/2. = -3
substitute value of x in second equation to get y
-3 - y = 2
-y = 2 + 3
-y = 5
y = -5
Why do equivalent ratios form a straight line when graphed?
The vertical distance between points is constant, and the horizontal distance between points increases with each point.
The ratio of the change in y-values to the change in x-values is equivalent for any two points in a graph of equivalent ratios.
The horizontal distance between points is constant, and the vertical distance between points increases with each point.
The y-values of equivalent ratios increase at a constant rate, and the x-values decrease at a constant rate.
Answer:
D-The y-values of equivalent ratios increase at a constant rate, and the x-values decrease at a constant rate.

Write the equation for the word problem
Devon became a waiter at a fancy restaurant. He makes $9 per hour. One night he made $150 in tips. How many hours did he work if he made a total of $226.50.
Answer:
9x + 150 = 226.50
Step-by-step explanation:
Devon makes $9 per hour. So, that signalizes "9x" (x representing the amount of hours he worked)
$150 represents how much he made one night, so you would add that to 9x. (9x + 150)
Finally, it gives you the total amount: 226.50
In conclusion, your equation should be: 9x + 150 = 226.50
Please answer the question over probability. Please explain the best that you can. Explain what you would do for question one and for question two. Solve and answer both and explain what you did to determine the answer. DO NOT JUST SOLVE
Problem 1 : You roll a spinner that is numbered 1-6. What is the probability of landing on a number greater than 4 and then landing on a 2? (determine the answer and explain your process for doing so)
Problem 2: You roll a six-sided die and you want to know the probabilty of rolling a 2 or a 4. What is the probability? (fraction and simplest reduced form)
Answer:
Problem 1: 1/18 (1/3 probability of greater than 4, then a 1/6 probability of landing on 2)
Problem 2: 1/3 (Chance of landing on 2 numbers out of 6)

Hailey used 2 2/3 liters of cola to completely fill 2 bottles. If the bottles are all the same size, how many liters of cola does each bottle hold? Enter your answer below
Answer:
they each hold 1 1/3 litters of cola
Step-by-step explanation:
Because if there is 2 2/3 liters of cola
then you either divide it by 2
or you can look at it and see what would add evenly to make that number
in this case it would be 1 1/3
1 1/3 +1 1/3= 2 2/3

What is the measure of
Answer:
x = 100 degrees

x = 180 - 80 = 100 degrees, because x and 80 are supplemental angles (They add up to 180 degrees)
pls help it should be ez for u guys
Answer: 950.3
Step-by-step explanation:
so the formula for the volume of a sphere is 4/3*pi*r^3
so plugging your information into the formula, you would get 4/3(pi)(6.1)^3
6.1^3 is the same as
(6.1) times (6.1) times (6.1)
this equals 226.981
now you have 4/3(pi)(226.981)
now you do 226.981/3 which equals 75.660333
multiply that by 4➡️ 302.6413333333333
now you have to multiply by pi (3.14)
302.6413333333333*3.14=
950.2937866666667
you have to round to the 10ths place
so your answer is 950.3 m cubed.

Pls help me. I'm begging TwT
Answer:
the answer is 46
Step-by-step explanation:
4×28/ 7×1 = 112/7
In this case, our new fraction can actually be simplified down further. To do that, we need to find the greatest common factor of both numbers.
We already did that, and the GCF of 112 and 7 is 7.
We can now divide both the new numerator and the denominator by 7 to simplify this fraction down to its lowest terms.
112/7 = 16
and do the same for 3/4 out of 16 then add ur answers
The angle measures of a triangle are shown in the diagram below. What is the value of x?
Answer:
30°, see explanation below!
Step-by-step explanation:
Hewo Again!
And for your question.
All of the inside angles of a triangle added together equals 180°!
So:
2x+2x+2x=180
6x=180
x=30°
Answer:
30
Step-by-step explanation:
i believe it is 60 because an equilater triangle like that has its angles as 60° and 60 ÷ 2 is 30.
