7+4=11 * -9= -99 hope this helped
Step-by-step explanation:
let E be weight of expensive nuts, C be cheaper nuts
E*8+C*5=10*6 value equation
E+C=10 mass equation
Solve it by any method, I will do determinants
Det: 8-5=3
E= (60-50)/3=10/3 =3.33 lb
C= 80-60 /3=20/3 =6.66 lb
Answer:
7/10
Step-by-step explanation:
You will have to use trial and error in order to find the values for x and y.
Just keep plugging values until you get 7.
I found x is equal to 2 and y is equal to 5.
3(2) + (1/5)5 = 7
6 + 5/5 = 7
6 + 1 = 7
7 = 7
Answer:
330
Step-by-step explanation:
The prism is a triangular prism
9 * (12 + 5 + 13) + (2 * 30)= 330
30 being the base area
