You're just changing the given rate into a unit rate: follow along and do the division shown and fill in the blanks. 320 ÷16 = 20

So the unit rate is \frac{20mi}{1gal}

Do 320/16 and that will equal 20 and don’t pay attention to the denominators because they already put a 1 for you.

Simplify 2x(5x + 3) + 7(5x + 3)
zubka84 [21]
Use distributive property to solve.
2x(5x+3) + 7(5x+3)
1. distribute

2x•5x = 10x^2
2x•3= 6x

10x^2+6x

7•5x = 35x
7•3= 21

35x+21

2. combine like terms

10x^2+6x+35x+21

10x^+ 41x +21 [final answer]

SOMEONE HELP! I know the answer I just need to show the work.
gayaneshka [121]

okay so

117° + angle a = 180° (supplementary angle)

angle a = 180 - 117

= 63°

then angle a + angle b + 81° = 180° ( angle sum property)

so... 63° + angle b + 81° = 180

144 + angle b = 180°

angle b = 180 - 144

= 36°

hope this helps.
