17. A man can row at 8 km/hr in still water. If the
river is running at 2 km/hr, it takes him 48
minutes to row to a place and coming back. How
far is the place ?
(a) 1 km
(b) 2 km en
(c) 3 km
(d) 4 km
Answer:
(c) 3 km
Step-by-step explanation:
Speed in still water: 8 km/h
Speed of river: 2 km/h
Speed downstream: 8 km/h + 2 km/y = 10 km/h
Speed upstream: 8 km/h - 2 km/h = 6 km/h
total time both ways: 48 minutes = 48/60 hour = 0.8 hour
time to go upstream: t
time to go downstream: 0.8 - t
speed = distance/time
s = d/t
d = st
Upstream:
d = st
d = 6t
Downstream:
d = st
d = 10(0.8 - t)
The distance upstream and downstream is the same.
6t = 10(0.8 - t)
6t = 8 - 10t
16t = 8
t = 0.5
d = 6t = 6(0.5)
d = 3
Answer: (c) 3 km

7(x + 1) = 21
Answer:
x = 2
Step-by-step explanation:
Given
7(x + 1) = 21 ( divide both sides by 7 )
x + 1 = 3 ( subtract 1 from both sides )
x = 2
Answer:
x=2
Step-by-step explanation:
7×(x +1)=21
7x +7 =21
7x =21 - 7
7x =14
x=14 :7
x=2
7 ×(2 +1)=21

What equation can Janet use to calculate the principal amount? (and please don't just answer try to solve it someone ripped me off, the last time i asked by just typing)
Answer:
t = [tex]\frac{l}{pr}[/tex]
Step-by-step explanation:
Formula or literal equation used to calculate the simple interest is,
l = prt
where 'l' = Simple interest
p = principle amount invested
r = rate of interest
t = time or duration of the investment
If we have to calculate the time of investment form the given formula,
l = prt
By the division property of equality,
[tex]\frac{l}{pr}=\frac{prt}{pr}[/tex]
[tex]t=\frac{l}{pr}[/tex]
Therefore, formula to be used is, [tex]t=\frac{l}{pr}[/tex]

Solve for x.
[tex]3x - 5 = \frac{12 + 4x}{2} [/tex]
x = [?]
Answer:
x= 11
Step-by-step explanation:
[tex]3x - 5 = \frac{12 + 4x}{2} [/tex]
Multiply both sides by 2:
2(3x -5)= 12 +4x
Expand:
2(3x) +2(-5)= 12 +4x
6x -10= 12 +4x
Bring all x terms to 1 side, constant to the other:
6x -4x= 10 +12
2x= 22
Divide by 2 on both sides:
x= 22 ÷2
x= 11

If x represents a number then write an expression for a number that is three more than one third the value of x
Answer:
1/3x+3
It is asking for 1/3 of x which is 1/3x
three more essentially means add 3
So 1/3x+3 is the answer
The expression is,
y = 1/3x+3
Where, y is number write with the help of x
And, x is a number.
Here,
We have to write an expression for a number that is three more than one third the value of x.
What is Number system?
A system of writing to express the number is called Number system.
Now,
x represents a number.
Let a number y which is written as, three more than one third the value of x.
One third of x = 1/3 x
Then, more than 3 means to add 3, we get
y = 1/3 x + 3
Hence, The expression is,
y = 1/3x+3
Where, y is number write with the help of x
And, x is a number.
