X=numerator
y=denominator
the sum of numerator and denominator=x+y
we suggest this system of equations:
y=x-3
(x+5) / (y+5)=5/6
we solve this system of equation by substitution method.
(x+5) / (x-3+5)=5/6
(x+5) / (x+2)=5/6
6(x+5)=5(x+2)
6x+30=5x+10
6x-5x=10-30
x=-20
y=x-3=-20-3=-23
Teh sum of the numerator an denominator=-20+(-23)=-43
Answer: -43
X jumpers at <span>£15 each. Total = 15*x = </span><span>£15x
</span>
y shirts at £12 each. Total = 12*y = <span>£12y
Total cost = </span><span>£15x + </span><span>£12y
Total cost = </span><span><span>£(15x + 12y)</span></span>
C
4 times the square root of 2 is 5.65... which rounds to 5.7
"b" represents the population of bobcats.
1) "t" represents the number of years after 2008.
2) The domain (t) starts at 0 (which is the year 2008) ⇒ t ≥ 0
3) The range (b) starts when t = 0. b =-0.32(0)² + 2.7(0) + 253 ⇒ b ≥ 253
4) The graph is discrete because the population must be in whole numbers.
Answer:
OPTION B - 41
Step-by-step explanation:
An expression is given and the corresponding values for the expression are also given. We have to substitute the given values to arrive at the answer.
The given expression is: x + 3y + z.
Also given: x = 4, y = 5, z = 22.
Substitute these values in the above expression, we get:
4 + 3(5) + 22 = 4 + 15 + 22 = 41.
∴ x + 3y + z = 41
