Answer:
It was a 16.7% discount
Step-by-step explanation:
You have to get the discount and divide it by the original price and it would be 0.16753 and so the percent becomes 16.7%

WRITE EQUATIONS....
f = k÷ g (inversely proportional....)
∴ if f= 40 and g= 5 K= (40×5) =200
now that u have k... and given g = 10...u can substitute to find f
f= 200÷10 =20
so f = 20
Answer:
18.61
Step-by-step explanation:
Principle = £4500
Time = 6yrs
Rate = n%
Simple interest = £5025
n = ?
We know,
SI =PTR/100
£5025 = £4500*6*n/100
£502500 = £27000*n
n = 18.61
Answer:
They are vertical angles
x = 5
The mesure of the angles are 35, 35, 145, and 145
Step-by-step explanation:
vertical angles are derectly acrost from each other.
the equations 3x+20 and 10x-15, put into the equation 3x+20=10x-15 will solve for x.
20 = 10x − 15 − 3x
20 = 7x - 15
20 + 15 = 7x
35 = 7x
35/7 = x
5 = x
x = 5
The equations solved are 3 x 5 + 20 = 35 and 10 x 5 - 15 = 35
The sum of all the angles is 360, therefore 35 + 35 = 70
360 - 70 = 290
290/2 = 145
The last two angles are 145 degrees
