Given that Z is the centroid of a triangle RST. This means that Z is the point of intersection of the three medians of the triangle.
So,W is the midpoint of RSV is the midpoint of RTWe are given that:RV = 4x + 3 and VT = 2x + 9
Since V is the midpoint, then:RV = VT4x + 3 = 2x + 94x - 2x = 9 - 32x = 6x = 3
Now put the value of x in WS = 5x-1WS = 5x-1WS = 5(3) - 1 WS = 15 - 1 = 14WS = 14
Since W is the midpoint of RS, therefore RW = WSand WS = 14Therefore:
RW = 14
Answer:
The cost of an oil change for 1 truck was $42
Step-by-step explanation:
Let
x -----> the cost of an oil change for 1 truck
y -----> the cost of gas for 1 truck
z ----> the total bill
we know that
![z=11[x+y]](https://tex.z-dn.net/?f=z%3D11%5Bx%2By%5D)
we have
![z=\$694.32](https://tex.z-dn.net/?f=z%3D%5C%24694.32)
![y=(6)(3.52)=\$21.12](https://tex.z-dn.net/?f=y%3D%286%29%283.52%29%3D%5C%2421.12)
substitute and solve for x
![694.32=11[x+21.12]](https://tex.z-dn.net/?f=694.32%3D11%5Bx%2B21.12%5D)
![x=(694.32/11)-21.12](https://tex.z-dn.net/?f=x%3D%28694.32%2F11%29-21.12)
![x=\$42](https://tex.z-dn.net/?f=x%3D%5C%2442)
Answer:
A
Step-by-step explanation:
The degree of a polynomial is determined by the largest exponent in the terms of the polynomial. The leading coefficient is the coefficient of the term with the largest exponent.
Given
f(x) = 2x³ + 2x² - ![\frac{1}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Bx%7D)
The term -
means that f(x) is not a polynomial
Since terms with division by a variable are not allowed.
well, i believe the answer is each dollar= 1.6 pounds
