[((2 / 75.5) - 3) * 2]3 (make 3 an exponent.)
Answer:
6x^7.
Step-by-step explanation:
The exponent property for this would be that
x^a * x^b = x^a + b.
So x^2 * x^5 = x^2 + 5 or x^7.
The other part is just multiplying the coefficients 3 and 2, which is 6.
Put these together and you get your answer 6x^7.
A=number of seats in section A
B=number of seats in section B
C=number of seats in section C
We can suggest this system of equations:
A+B+C=55,000
A=B+C ⇒A-B-C=0
28A+16B+12C=1,158,000
We solve this system of equations by Gauss Method.
1 1 1 55,000
1 -1 -1 0
28 16 12 1,158,000
1 1 1 55,000
0 -2 -2 -55,000 (R₂-R₁)
0 12 16 382,000 (28R₁-R₂)
1 1 1 55,000
0 -2 -2 -55,000
0 0 4 52,000 (6R₂+R₃)
Therefore:
4C=52,000
C=52,000/4
C=13,000
-2B-2(13,000)=-55,000
-2B-26,000=-55,000
-2B=-55,000+26,000
-2B=-29,000
B=-29,000 / -2
B=14,500.
A + 14,500+13,000=55,000
A+27,500=55,000
A=55,000-27,500
A=27,500.
Answer: there are 27,500 seats in section A, 14,500 seats in section B and 13,000 seats in section C.
2 years is 24 months
24/4=6
Barb will eat 6 times more in 2 years than in four months.
Six times six equals 36
