Divide the top number by the bottom number
129 degrees you just add DCE and ECF together
1/6p + (-4/5) is the equivalent expression. You have to add like terms, meaning constants are added to constants, variables are added to variables, etc. the result you get from adding like variables leaves you with 1/6p + (-4/5) or 1/6p - 4/5
C^2=a^2+b^2 we are given the hypotenuse of 19 units and one leg of 8 units so:
19^2=8^2+b^2
361=64+b^2
b^2=297
b=√297
b≈17.2 to the nearest tenth
Let’s designate the number of banana splits sold as x. That means the number of sundaes sold is x + 8.
Now if we put this into an equation, also keeping in mind their costs, we get:
3(x) + 2(x + 8) = 156
Now to solve for x:
3x + 2(x + 8) = 156
3x + 2x + 16 = 156
5x = 140
x = 28
That means you’ve sold 28 banana splits and 36 sundaes! :)
