Mr. Au went to eat at McDonald's this week. On Monday, he ate some hamburgers. On Tuesday, he ate nothing at McDonald's. On Wedn
rewona [7]

Answer: See explanation

Step-by-step explanation:

Let the number of hamburger he ate on Monday be represented by x.

Monday = x

Tuesday = 0

Wednesday = x + 4

Thursday = 0

Friday = 3(x + 4)

Total hamburgers ate = 26

To find the amount of hamburger ate each day we add the number of hamburger ate per day all together. This will be:

= x + 0 + x + 4 + 0 + 3(x+4) = 26

2x + 4 + 3x + 12 = 26

5x + 16 = 26

5x = 26 - 16

5x = 10

x = 10/5

x = 2

Monday = x = 2 hamburgers

Tuesday = 0

Wednesday = x + 4 = 2 + 4 = 6 hamburgers

Thursday = 0

Friday = 3(x + 4) = 3(2 + 4) = 18 hamburgers

For the rotation - 660°, find the coterminal angle from 0° &lt; 0 &lt; 360°, thequadrant and the reference angle.
guajiro [1.7K]

Given the angle:

-660°

Let's find the coterminal angle from 0≤θ≤360.

To find the coterminal angle, in the interval given, let's keep adding 360 degrees to the angle until we get the angle in the interval,

We have:

Coterminal angle = -660 + 360 = -300 + 360 = 60°

Therefore, the coterminal angle is 60°.

Since 60 degrees is between 0 to 90 degrees, is is quadrant I.

60 degrees lie in Quadrant I.

Also since it is in quadrant I, the reference angle is still 60 degrees.

ANSWER:

The coterminal angle is 60°, which lies in quadrant I, with a reference angle of 60°

Solve for x.<br> - 30 – 5x - 1) + 7 = - 110
ololo11 [35]

Answer:

x =  \frac{86}{5}   = 17 \frac{1}{5}  = 17.2

Step-by-step explanation:

( - 30 - 5x - 1) + 7 =  - 110

( - 31 - 5x) + 7 =  - 110

- 31 - 5x + 7 =  - 110

- 24 - 5x =  - 110

- 5x =  - 110 + 24

- 5x =  - 86

\boxed{\green{x =  \frac{86}{5}   = 17 \frac{1}{5}  = 17.2}}
