Answer:
you would evaluate the factions
Step-by-step explanation:by dividing
Answer:
7)
Step-by-step explanation:
The pattern is: add two more than you did before: starting from 2.
It would be:
1, 3, 7, 13, 21, 31, 43, 57
+2 +4 +6 +8 +10 +12 +14
Now use this to answer the questions.
Hope this helped!
Have a nice day!
(it would be nice if you gave me brainliest)
Thx :)
The speed of the current is 25 kilometers per hour.
<h3>What is the speed of the current?</h3>
According to the statement, Naira traveled first with the current and later against the current, both in the same amount of time. We assume that both the speed of the current and the speed of the vehicle are constant. Hence, the travel time can be expanded to the following expression:
s₁ / (v + v') = s₂ / (v - v')
Where:
- s₁ - Distance traveled with the current, in kilometers.
- s₂ - Distance traveled against the current, in kilometers.
- v - Speed of the current, in kilometers per hour.
- v' - Speed of the vehicle relative to the current, in kilometers per hour.
If we know that s₁ = 4.5 km, s₂ = 3 km, v' = 5 km /h, then the speed of the current is:
4.5 / (v + 5) = 3 / (v - 5)
4.5 · (v - 5) = 3 · (v + 5)
4.5 · v - 22.5 = 3 · v + 15
1.5 · v = 37.5
v = 25
The speed of the current is 25 kilometers per hour.

Answer: X=1/72
Step-by-step explanation:
3/8x-17=10
We move all terms to the left:
3/8x-17-(10)=0
Domain of the equation: 8x!=0
x!=0/8
x!=0
x∈R
We add all the numbers together, and all the variables
3/8x-27=0
We multiply all the terms by the denominator
-27*8x+3=0
Wy multiply elements
-216x+3=0
We move all terms containing x to the left, all other terms to the right
-216x=-3
x=-3/-216
x=1/72
Length of the mid-segment = (long base + short base) / 219 = (27 + short base) / 219 - (27 / 2) = short base / 2Multiplying both sides by 238 -27 = short baseshort base = 11
