Answer:
the sum of the given matrices is
-7 -2
4 -15
We are given with the combination ratio of ostrich eggs and duck eggs to produce a scramble and equivalently another ratio to make one. In this case, the algebraic expression would be:
2 + 14 x = 5
14x = 3
x = 3/14
The ratio thus of duck egg to ostrich egg is 3 duck eggs/14 ostrich eggs
0.21 duck eggs per ostrich egg
Answer:
11.05$
Step-by-step explanation:
Given the wholesale price of pillow is $6.50
Price in department store is 70% more than whole sale =1.7 times the wholesale
Price in department store =1.7*6.5=$11.05

Answer:
x =70
Step-by-step explanation:
The variation model we'll need here is y = kxz, where k is the constant of proportionality. We are told that when y = 105, x = 2 and z = 9. This gives us enough info with which to calculate k:
9 = k(2)(9), or 1 = 2k, or k = 1/2.
Then the governing equation is
y = (1/2)xz.
If y = 105 when z = 3, then we have 105 = (1/2)(x)(3).
To solve this for x, first multiply both sides by 2, obtaining 210 = 3x.
Finally, we divide both sides by 3, obtaining the final result x = 70
