Answer: a₁₁ = -11 a₁₂ = -16 a₁₃ = 6 a₁₄ = -10
<u>Step-by-step explanation:</u>
"A" represents the following matrix of unknown values [a₁₁ a₁₂ a₁₃ a₁₄]
[a₁₁ a₁₂ a₁₃ a₁₄] + [11 17 -8 13] = [0 1 -2 3]
a₁₁ + 11 = 0 --> a₁₁ = 0 - 11 = -11
a₁₂ + 17 = 1 --> a₁₂ = 1 - 17 = -16
a₁₃ + -8 = -2 --> a₁₃ = -2 + 8 = 6
a₁₄ + 13 = 3 --> a₁₄ = 3 - 13 = -10
Answer:
in total she would spend 27.90 so she should bring C i got this by doing 7.80 x 3 because she is buying 3 medium pizzas then i did 0.75 x 6 and got 27.90 so at least bring 25-30 dollars with her

Answer:
(38.8%...7/10), than (47%...8/17) I didnt know if u needrd it in fraction or percent.
Step-by-step explanation:
You want to first add up everyone. So in total there are 18 people.
There is than a 38.8% chance that a independent will be picked first. 7/18.
But since one person was picked already you have to subtract 1 person from the total, so now its out of 17.
There is now a 47% chance that a democrat will be picked next. 8/17.
Answer:
(5/3 x - k)/c =b
Step-by-step explanation:
x = 3 / 5 (cb+k)
Multiply each side by 5/3
5/3x =5/3* 3 / 5 (cb+k)
5/3x = (cb+k)
Subtract k
5/3 x - k = cb +k-k
5/3 x - k = cb
Divide by c
(5/3 x - k)/c = cb/c
(5/3 x - k)/c =b
