Answer:
A unit rate means a rate for one of something. We write this as a ratio with a denominator of one. For example, if you ran 70 yards in 10 seconds, you ran on average 7 yards in 1 second. Both of the ratios, 70 yards in 10 seconds and 7 yards in 1 second, are rates, but the 7 yards in 1 second is a unit rate.
Answer:
so 1- 2 is negative 3 so minus tha by 3 than 4x2

Answer:
Step-by-step explanation:
To write any polynomial in standard form, you look at the degree of each term. You then write each term in order of degree, from highest to lowest, left to write.
To add the polynomials you need to:
Remove parentheses
Group like terms
Add similar elements
-7 = 2x + 8
Solve for x. First subtract 8 to both sides.
-7 - (8) = 2x + 8 - (8)
-15 = 2x
Divide by 2.
-15/(2) = -2x/(2)
x = -15/2 = -7.5
