Answer:
x + y = 15
0.5x + 0.65y = 9
Step-by-step explanation:
x = number of oranges
y = number of apples
total of apples and oranges is 15 so x + y = 15
total cost of apples and oranges is $9 so 0.5x + 0.65y = 9
Calculation
y = 15 - x
0.5x + 0.65(15-x) = 9
0.5x - 0.65x + 9.75 = 9
-0.15x = - 0.75
x = 5
y = 15 - x = 15 - 5 = 10
So the number of pencils bought can be represented by an equation:
, where n is the number of notebooks bought. Since Helen bought 5 notebooks, simply plug 5 into n:
. So Helen bought 12 pencils.
Angle B equals angle D
angle A equals angle C
so △ABE =△CDE
i think thats the answer
