Answer:
x = -11
Step-by-step explanation:
I'm going to assume 80 and 60 are vertical angles so:
x + 51 + 80 + 60 = 180
x + 191 = 180
x = -11
The volume of the rectangular prism is 90 cubic units.
Step-by-step explanation:
The volume of the cube is given by the product of length,width and height
v=l*w*h where v is volume in cubic units, l is length in units, w is width in units and h is height in units
In this case, l=6 units, w=3 units and h = 5 units
The volume will be;
v= l*w*h
v=6*3*5
v=90 cubic units

Answer:
not because you are rounding to the nearest tenth
Step-by-step explanation:
Here you have two unknowns, so you would need two equations (system of equations). By using w to represent walnuts and c to represent chocolate chips your equations would be 5w + 2c = 10 and 3w + 8c = 23, the coefficients being the amount of pounds of walnuts and chocolate chips and the right hand side of the equations being the total price. From there you can either solve for one variable in terms of the other and plug in to the other equation, or you could subtract one equation from the other ( I personally prefer solving for one variable in terms of the other and then plugging in to the other equation).
