Me asap ! give me the perimeter and with ! !

if the triangle is equilateral,

AB=AC

4x-3=2x+11

=>x=7

side length=4(7)-3=25

perimeter=3×side length=75

6 mangoes

0.38 or 38p

Step-by-step explanation:

Apparently the value of the mango is £ 0.77, which means that to get the number of mangoes you can buy, you must divide this value to the amount of money you have, that is, £ 5

5 / 0.77 = 6.49

which means that it is enough for 6 mangoes.

To know the change, multiply the value of one by 6 and subtract it with £ 5, it would be the change.

6 * 0.77 = 4.62

5 - 4.62 = 0.38

That is, the change is £ 0.38 or 38p
