Answer:
x=17
Step-by-step explanation:
the two segements equal each other, so make teh equations equal eachother and solve for x ,2x-10=x+7
Answer:
28
Step-by-step explanation:
So this means to replace the r you see in 4r^2-8 with 3.
Let's do that:
4(3)^2-8
Now to simplify this just use pemdas or a calculator:
4(9)-8 since 3^2 means 3*3=9
36-8
28
Answer:
4500 meters.
Step-by-step explanation:
1 meter = 1000 millimeters so just do the number of meters (in this case 4.5) times 1000.
Divide both sides by 4:
3:5
Step-by-step explanation:
A linear equation in two variables can be described as a linear relationship between x and y, that is, two variables in which the value of one of them (usually y) depends on the value of the other one (usually x). In this case, x is the independent variable, and y depends on it, so y is called the dependent variable
