Y is 3.5
19 - 5 is 14
14/4 is 3.5
Answer:
5x+9 = 109
3x+11 =71
Step-by-step explanation:
A linear pair adds to 180
5x+9 + 3x+11 =180
Combine like terms
8x + 20 =180
Subtract 20 from each side
8x +20-20 = 180-20
8x = 160
Divide each side by 8
8x/8 = 160/8
x=20
5x+9 = 5*20+9 = 100+9 = 109
3x+11 = 3*20+11 = 60+11=71
Answer:
$1,920
Step-by-step explanation:
you multiply 12 by 40. then, assuming a typical month is 4 weeks, you multiply that number by 4.
Answer:
Step-by-step explanation:
12 yd : 20 yd
both has yd on both sides, this means 12:20 = 12/20
12/20 simplified: 3/5
If is the distance the runner travels between first and second base, then the distance between him and home plate satisfies
(where the 90 here refers to the distance between first base and home)
Differentiating both sides with respect to time gives
The runner's speed is . When he is away from first base, he is
away from home plate. So he is moving away from home plate at a rate of
