Y + -4 = 9 (this means y plus negative 4 equals 9)
y -4 = 9
+4 +4
y = 13
X = 89
41 + 50 = 91 which is 89 away from 180
Step-by-step explanation:
1. 42m below the sea level.
2. you withdrawn 42 dollars from 100.
3. -14°C or -14°F or -14K.
4. your height increased from 242inches to 245 inches. your height increased by 3 inches !
hope this helps you.
<em><u>The system of equations that represents this situation are:</u></em>
q + p = 2
4q + 5p = 8
<em><u>Solution:</u></em>
Let q be the number of hours it took Courtney to walk from her house to the beach
Let p be the number of hours it took her to walk from the beach to the park
<em><u>The entire walk took 2 hours</u></em>
Therefore,
q + p = 2 ------- eqn 1
<em><u>The total distance Courtney walked was 8 kilometers</u></em>
Total distance = 8 km
Courtney walked from her house to the beach at a constant speed of 4 kilometers per hour
Then walked from the beach to the park at a constant speed of 5 kilometers per hour
<em><u>Distance is given as:</u></em>
<em><u>From her house to the beach:</u></em>
<em><u>From the beach to the park:</u></em>
We know that,
Total distance = 8 km
Therefore,
4q + 5p = 8 ------ eqn 2
<em><u>Thus the system of equations that represents this situation are:</u></em>
q + p = 2
4q + 5p = 8
4πr2
= 4×π×42
= 64π
= 201.06192982975 inches2
The answer should be the last one
