Answer:
150 miles
Step-by-step explanation:
Find the unit rate (MPH) by dividing miles travlled by hours.
300/6 = 50 MPH
250/5 = 50 MPH
Multiply the hours on day 3 (3) by 50 MPH
3*50 = 150 miles
6x+5= 9x-4
9=3x
3=x
To find RS you need to substitute x back into the equation
9(3)-4
27-4
23
23 is the answer
Showing fractions with models is giving a visual and sometimes can be easier to process.They also can be in picture form or other.Ex. A piece of pizza cut into fourths.
Showing fractions on a number line is also giving a visual but still allows you to add and subtract using numbers if that makes sense.Ex.

brainly.com/question/10192511Knowing that 1+2i is a root, you also know that 1-2i is a root, so one quadratic factor is
(x -1)² -(2i)² = x^2 -2x +5
Long division of the given polynomial by this quadratic gives a quotient of
x² +9
which has roots ±3i.
Then all
the roots are {-3i, 3i, 1-2i, 1+2i}.
