2x +9 = 3x - 1

2x - 3x = -9 -1

-x = -10

x = 10

2(10) + 9 = 29

so angles 1 and 3 measure 29 degrees

360 - 2(29) = 302 degrees

302/2 = 151 degrees

so angles 1 and 3 measure 151 degrees

2x + 9 = 3x - 1

9 + 1 = 3x - 2x

10 = x

2(10) + 9 = 29

angle 1 and 3 is 29°

180 - angle 3 = angle 4

180 - 29 = 151

angle 4 and 2 is 151°

Answer:

y = 6 when x = 18

Step-by-step explanation:

The appropriate formula for this direct proportion is y = kx, where k is the constant of proportionality.

We know y = 3 when x = 9: 3 = k(9)

This yields k = 3/9, or k = 1/3

Then the formula is y = (1/3)x

and when x = 18, y = (1/3)(18) = 6

y = 6 when x = 18

T divided by 5/12 =-3/10<br><br><br> t=____

damaskus [11]

Answer:

Step-by-step explanation:

t ÷ 5/12 = -3/10

t * 12/5 = -5/10

$t=\frac{-3*5}{10*12}\\\\t=\frac{-1*1}{2*4}\\\\t=\frac{-1}{8}$

Two balls A and B rotate along a circular track. Ball A makes 4 full rotations in 120 seconds. Ball B makes 3 full rotation in 6

lara [203]

Find the rate in which both balls make one full rotation around the track.

Ball A:

$120 / 4 = 30$

It takes 30 seconds for Ball A to make a full rotation.

Ball B:

$60 / 3 = 20$

It takes 20 seconds for Ball B to make a full rotation.

Find the least common multiple of 20 and 30 to find the time at which they'll meet.

Multiples of 20: {20,40,60}
Multiples of 30: {30,60}

60 is the least common multiple of both 20 and 30.

The balls will meet again at 60 seconds.
