Step-by-step explanation:
It depends in the type on interest
Simple Interest
PxRxT
£240 x 0.07x 3 = £50.4
£240 + £50.4 = £290.4
Compound Interest
Px(1+R)^T
£290.4 x (1 + 0.07)³ = £355.7524872= €355.76

<h3>
<em><u>x=3 or x=-10</u></em> is the right answer.</h3>
Answer:
A = 110 degrees.
Step-by-step explanation:
< A and < B are same side angles so their values add up to 180 degrees, so:
5x + 20 + 9x - 92 = 180
14x - 72 = 180
14x = 252
x = 18.
So m A = 5(18) + 20
= 110 DEGREES.
Answer:
-4=x
Step-by-step explanation:
1) 1-2x=-x-3 (letter's to the left)
2) then you get 1-x=-3
3) then you subtract 1 on both sides
4) then you dived the -1
5)answer -4=x
