Answer:
58 degrees
Step-by-step explanation:
If angle 1 + angle 2 = 90 degrees, then:
(3x - 4) + (4x+10) = 90
Combine like terms:
(3x+4x) + (10-4) = 90
7x + 6 = 90
Subtract 6 from both sides:
7x = 84
Divide both sides by 7:
x = 12
**Plug x back into angle 2 (This step is easy to forget!):
angle 2 = 4(12) + 10
angle 2 = 48 + 10
angle 2 = 58 degrees
Answer:
0.59 cents
Step-by-step explanation:
To find how much he paid for 1 pound, you divide $19.20 by 2 = $9.60

Answer:
2.66 days
Step-by-step explanation:
We know that a day has 24 hours, so if Roger sleeps 3/8 of a day that means that he sleeps 3/8 • 24 which equals to 9 hours.
Now we want to know how many days it takes Roger to sleep an equivalent of a day if he sleeps 9 hours a day. So:
24 h / 9 h = 2.66 days
Of course we can do it in an easier way, in fractions:
1 : 3/8 = 8/3
8/3 = 2.66 days
