Answer:
41 empty chairs.
Step-by-step explanation:
Banquet has (22)(4) tables and (15)(6) tables, subtracted by 3.
22 x 4 = 88
15 x 6 = 90
178 - 3
175 chairs.
Subtract 175 by 134 and you have the amount of empty chairs.
41 chairs.
A = # of adults = 3
s = # of students = 5
9(3) + 6(5) =
27 + 30 =
57

Step-by-step explanation:
<u>Division of Rational Expressions</u>
When dividing two rational expressions like f(c) / g(c), it's usually easier to multiply the numerator by the reciprocal of the denominator: f(c) * (1/g(c)). The reciprocal is just flipping the numerator and the denominator.
Let's find the following division:
First, we factor the polynomials where possible.
Substituting:
Multiplying by the reciprocal of the denominator:
Simplifying by (c+8)(3c+2)(c-8):
Answer:
Make this on form of a simultaneous equation:
assume jelly beans is J and trail mix is T
8J+4T=21
3J+2T=9
then solve
multiply the first equation by 3 and second equation by 8(SO THE J CAN DISAPPEAR[ELIMINATION METHOD])
24J+12T=63
24J+16T=72
Subtract
-4T=-9
T=0.44
then substitute the T to any one of the equation
3J+2(0.44)=9
3J+0.88=9
3J=8.12
J=2.71
therefore, jelly beans= $2.71 and trail mix=$0.44
Answer:
2(x^2)-1
Step-by-step explanation:
The square of a number is just the number squared. We don't know what the number is so I will just say it is x. So we have 2 times x^2. Then we have to minus 1 from that. So 2(x^2)-1.
Hope this helps! :D
