4)

12/16=21/b

multiply both sides by b
(12/16)b=21

now multiple both sides by (16/12)
b = 21 (16/12) =28

5)
rate is distance / time or time/distance

train travels 279 km per 1.5 hr =270/1.5
or
1.5 hr per 270 =1.5/27p

answer choice a and c matches that.
looking at choice C...270km/1.5hr=5hr/270km

looking at choice A.. 1.5hr/270km=5hr/k km

the units don't match for choice C so the

right answer is A

6)

1.5/270=5/k

multiply both sides by k
(1.5/270)k=21

now multiple both sides by (270/1.5)
k = (270/1.5)21= 900

7) 75 points per 6 game

75 points / 6 games

75/6=P/20

multiply both sides by 20
(75/6)20=P

P=250

Find the value of x that will make A||B
Arturiano [62]

Answer:

x=20

Step-by-step explanation:

Both Angles have the same value, as they are opposite angels.

Set your formula up as

5x+20=3x+60

5x=3x+60-20

2x=40

x=40/2

x=20

Two airplanes are flying to the same airport. Their positions are shown in the graph. Write a system of linear equations that re
wariber [46]

Answer:

Airplane #1 equation: y=5/13x+42/13

Airplane #2 equation: y=1/3x+14

Step-by-step explanation:

So to find the slope of each airplane, you use the formula y2-y1/x2-x1. That means, for airplane#1 the equation will be 9-4/15-2. Simplify this and get 5/13. Then, for airplane#2, the equation will be 12-9/6-15. Simplify this and get 3/-9 and divide each side by 3 to get 1/-3 or -1/3. Next, use point slope formula to find the system of linear equations. Point slope formula is y-y1=m(x-x1). M is the slope. Use any point from the line. In this case, I will use (2,4). Tat means the first airplane's equation would be y-4=5/13(x-2). Then y-4=5/13x-10/13. Then, convert four into a fraction with a denominator of 13. This means, you have to multiply 4 by 13 to get 52/13. Add 52/13 to -10/13 to get 42/13. That means the first equation will be y=5/13x+42/13. The second equation point will be (6,12). This means the equation will be y-12=-1/3(x-6). Simplify this to get y-12=-1/3x+2. Simplify this to get y=1/3x+14. Therefore, Airplane#1 equation will be y=5/13x+42/13 and airplane #2 equation will be  y=1/3x+14.

Hope this helps
