Answer:
One cup of coffee is $3.25
Step-by-step explanation:
Create a system of equations where c is the cost of a cup of coffee and d is the cost of a donut
2c + 4d = 10.5
c + 5d = 8.25
Solve by elimination by multiplying the top equation by -5 and the bottom equation by 4
-10c - 20d = -52.5
4c + 20d = 33
Add them together and solve for c
-6c = -19.5
c = 3.25
So, a cup of coffee is $3.25
Answer:
try the 3rd one
Step-by-step explanation:
if it's not right then i'm sorry
16-4=12
12x5=60
I'm putting together assumptions as this isn't really clear to me, I apologize.
Isosceles right triangles are half squares, and if the length of one side is 6cm, that is the length of the other side since both segments are equal. Take the formula to find the area of a square (base times height), apply the side measurement of the triangle (6cm) and divide it in half to find the area of half of it (therefore, finding the area of the isosceles triangle.)
(6x6) / 2
6x6 = 36
36 / 2 = 18
The area of the isosceles triangle is 18 square centimeters.
Ur answer will be - A≈69.65cm².
