Answer:
Step-by-step explanation:
A) We use this relation: Distance = time * speed ( speed or vitesse or rate)
So d= 3.4*t= 3.4t (miles)
B) If t= 5/8
then the distance d= 3.4* 5/8= 2.125 miles.
C) If the distance d= 5.44, we can find the time like:
d= 3.4*t, and we know d=5.44
so 5.44= 3.4*t or t = 5.44/3.4, t= 1.6 hours
Hope you understand it.
75 + x + 4x = 180
5x= 105
x = 21
< A = 21
< B = 84
3/4 is bigger then 3/10
Hint: Draw it out, and it will be a lot easier. They have different denominators:)
Product means multiply, so the product of 12 and 8 would be written as 12 x 8
Then you want 6 less than that so you need to subtract 6
The equation should look like (12 x 8) - 6
Answer:
rectangular equation, or an equation in rectangular form is an equation composed of variables like xx and yy which can be graphed on a regular Cartesian plane. For example y=4x+3y=4x+3 is a rectangular equation.
A curve in the plane is said to be parameterized if the set of coordinates on the curve, (x,y)(x,y) , are represented as functions of a variable tt .
x=f(t)y=g(t)x=f(t)y=g(t)
These equations may or may not be graphed on Cartesian plane.
