X/2 -5=20 please give details
Answer: x=50
how?
[tex]\frac{x}{2}[/tex] - 5= 20 (first ADD 5 with 20 whatever you do on one side you have to do it to the other) so that gives us:
[tex]\frac{x}{2}[/tex]=25 (we see that 2 is being divided by x and we want X alone so the inverse of division is MULTIPLICATION)
25 x 2= 50
therefor the x=50
Please help me solve this
Answer:
Step-by-step explanation:
This number is much larger than 1. You need to start at the decimal and move left (that's how scientific notation works for numbers larger than 1.)
So the answer is 1.0054 * 10 ^7
The person doing this started at the 1 and moved right until he/she hit the decimal. Wrong direction.

Jane invests £300 at a simple interest rate of 4.5% per year. At the end of each year, Jane gives the interest to a charity Work out the least number of years it will take for the total amount given to the charity to be greater than £50. Show your workings.
Answer:
At least 4 years
Step-by-step explanation:
Simple interest is given by
I = Prt
so here, one year's interest is
I = 300(.045) = 13.5
Divide 50 by 13.5 and get 3.7 years...thus
she will need four years to donate 50...
Step-by-step explanation:
Interest Rate = (Simple Interest × 100)/(Principal × Time).
given
Principal(P) = 300
Interest Rate(I.R) = 4.5%
Simple Interest(S.I) = 50
required
Time(T)
I.R = (S.I × 100)
(P ×T)
T × I.R = (S.I × 100) ×T
I.R (P × T) × I.R
T = (S.I × 100)
(P × I.R)
= (50 × 100)
(300 × 4.5)
= 5000

In a river, a trout passed beneath a woman who was swimming at 1,800 centimeters per minute. The trout swam 8,000centimeters directly upstream at a constant velocity. It swam that distance in 0.8minutes. What was the trout's velocity?
Write your answer as a whole number.
centimeters per minute upstream
Answer:
It would approximately be 3.73 m/h
Step-by-step explanation:
0.8 mins is 48 seconds
I then divided 8000 by 48 seconds to see how many cm it traveled per second.
It traveled 166.666666667 cm per second
I then converted cm to feet
so it was 5.468066491699474 feet per second
I then converted feet to miles, so it was 0.0010356186537309611598 miles per second.
Then I multiplied it by 60 so it was 0.06213711922 miles per minute.
Finally I multiplied it by 60 again to make it 3.72822715343 miles per hour.
I rounded it to the nearest hundredth making it 3.73 m/h
Stephen was thinking of a number. Stephen divides by 5 then adds 1 to get an answer of 21. Form an equation with
x
from the information.
Answer:
x/5 +1 = 21
Step-by-step explanation:
x is your variable. first step is divided by 5, so you put x/5. then it says add 1 so simply add it on to the equation x/5 + 1. the entire equation equals to 21 so you put the equal sign after x/5 +1 =21

What is the value of W in a exterior angle theorem
Answer:
26
Step-by-step explanation:
The sum of two interior angles in a triangle is equal to an exterior angle that is supplementary to the third interior angle.
so:
30 + 2w - 8 = w + 48
22 + 2w = w + 48 export like terms to the same side of the equation
2w - w = 48 - 22 subtract
w = 26

please help me solve x please
Answer:
x = 5
Step-by-step explanation:
The exterior angle theorem states that the measure of each exterior angle of a triangle is equal to the sum of the opposite and non-adjacent interior angles.
In the given problem, the exterior angle is < B, and the non-adjacent interior angles are < D and < C.
Given that:
< B = 12x + 8
< D = 8x + 8
< C = 20°
Set up the following formula to solve for x:
(8x + 8) + 20 = 12x + 8
Combine like terms:
8x + 28 = 12x + 8
Subtract 8 from both sides:
8x + 28 - 8 = 12x + 8 - 8
8x + 20 = 12x
Subtract 8x from both sides:
8x - 8x + 20 = 12x - 8x
20 = 4x
Divide both sides by 4 to solve for x:
20/4 = 4x/4
5 = x
Therefore, x = 5.
