Answer:
24
Step-by-step explanation:
4x + 6 = 102
-6. -6
4x= 96
x=24
Sum of all angles of triangle=180°
So, 102 + 4x + 6 + x = 180
or 5x + 108 = 180
or 5x = 180 - 108
or 5x = 72
or x = 72/5
or x = 14.5
So, x = 14.5°
please help me with this IXL i only have an hour like i said on my last question and please tell me how to get the answer so i can do the IXL on my own plz!
Answer:
y=2x-6
Step-by-step explanation:
The slope of a line shows the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.

Step-by-step explanation:
Isabelle takes the bus to work. The bus ride to work costs her $2.50 each time. She could buy a bus pass for a one-time fee of $15.00 and would then only pay $1.00 each time to ride the bus. How many times would she have to take the bus for the cost to be the same?
y = total cost
x = amount of times she takes the bus
Let's create two equations to model the data in the problem above.
y = $2.50x
y = $1x + $15
Now, let's set them equal to each other and solve for x.
$2.50x = $1x + $15
Subtract $1x from both sides.
$1.50x = $15
Divide both sides by $1.50
x = 10
She would have to ride the bus 10 times for the cost to be equal.
Answer:
10 Trips
Step-by-step explanation:
Create 2 algebraic Equations, X is the number of trips and y is the total cost. y=2.5x, and y=x+15. Set them equal to eachother and solve for X. 2.5X=X+15. Subtract X from both sides to get 1.5X=15. Divide by 1.5 to get 10. X=10, 10 Trips!

Answer: The slope is 6.
Step-by-step explanation:
One way to see the slope is to look at the graph and find places where the graphed line crosses the corners formed by the grid lines. Then count the number from top to bottom and divide that number by the number of blocks left to right (IF the scale is the same for both the x-axis and y-axis!) Then divide up-down number by left-right number. If it is the same, the slope is 1.
Here the line crosses the y axis at -1 exactly: (0, -1) The next place where it crosses the corner exactly is at (1, 5). Counting blocks: 6 from top to bottom, only 1 left to right 6/1
Or do it with the numbers: Find the difference in y-values, them divide by the difference in x-values, Using Coordinates (0,-1) and (1,5) the difference in y-values is 5-(-1) = 5+1 = 6 The difference in x-values is 1 - 0 = 1 6÷1 = 6

i need to find the inequality and make an equation to graph out of this : Carlos and Clarita want to sell T-shirts with dogs and cats on them. They’ve found two local t-shirt companies. Shirts R Us will charge them a one-time set up fee of $20 and $15/t-shirt. The second company, Tee4U, has a $50 set up fee and charges $12/t-shirt.
(I mean no need to waste points)
Answer:
Shirts R Us: 15t+20; Tee4U: 12t+50
If you're making a graph, shirts r us will start at (0,20) and will increase by 1 across and 15 up. tee4u will start at (0,50) and increase by 1 across and 12 up.

How do the different processes of the rock cycle, including tectonic forces, change one rock type into another?
Answer:
The three processes that change one rock to another are crystallization, metamorphism, and erosion and sedimentation. Any rock can transform into any other rock by passing through one or more of these processes. This creates the rock cycle.
1. The relationship between a distance in yards (y) and the same distance in miles (m) is
described by the equation y = 1760m.
a. Find measurements in yards and miles for distances by filling in the table.
distance measured in miles
distance measured in yards
1
5
3,520
17,600
b. Is there a proportional relationship between a measurement in yards and a
measurement in miles for the same distance? Explain why or why not.
Therefore, the ratio of yards to miles is always constant, making it a proportional relationship.
What is equation?An equation is a mathematical statement that shows the equality between two expressions. It typically includes one or more variables, which are unknowns that can take on different values. An equation can be solved by finding the value or values of the variable(s) that make both sides of the equation equal.
Here,
a. Using the equation y = 1760m, we can fill in the table as follows:
distance measured in miles distance measured in yards
1 1,760
5 8,800
3.520 6,195.2
17,600 30,800,000
b. Yes, there is a proportional relationship between a measurement in yards and a measurement in miles for the same distance. The equation y = 1760m shows that the number of yards is always 1760 times greater than the number of miles. This means that if you double the number of miles, the number of yards will also double, and if you triple the number of miles, the number of yards will triple, and so on.
