-113.2 °F
Step-by-step explanation:
Well assign the coldest place on earth on the day as having <em>x</em> temperature
Therefore based on the statement;
2x – 53.6 = -280
2x = -280 + 53.6
2x = - 226.4
X = -113.2

Hanna bought 85 candies and ate 20 of them. How many candies are left?
Answer:
10/13 ≤ x < 18/13
Step-by-step explanation:
-1 ≤ 13x - 11 < 7
If a ≤ u < b then a ≤ u and u < b
⇒ -1 ≤ 13x - 11 and 13x - 11 < 7
-1 ≤ 13x - 11
Add 11 to both sides: 10 ≤ 13x
Divide both sides by 13: 10/13 ≤ x
13x - 11 < 7
Add 11 to both sides: 13x < 18
Divide both sides by 13: x < 18/13
Combine the intervals
10/13 ≤ x < 18/13
Answer:
67
Step-by-step explanation:
Complementary angles add to 90 degrees
<A + <B = 90
x+10 + 3x+28 = 90
Combine like terms
4x+38 =90
Subtract 38 from each side
4x+38-38 = 90-38
4x = 52
Divide by 4
4x/4 = 52/4
x = 13
We want to find <B
<B = 3x+28
= 3(13) +28
= 39+28
=67
