Answer:
x=12
33 calls
Step-by-step explanation:
For 3/7 = x/28
Cross multiply. 3•28 = 7x
Seriously just use a calculator. But if you're not allowed to, then go ahead and do the next step which is divide by 7.
(3•28)/7 = x
The 28/7 is just 4.
You still have the 3.
3•4 = x
12 = x
SECONDLY,
Compare
calls/hour= calls/hour
18/6 = c/11
18/6 can be simplified. It is 3/1.
3/1 = c/11
Crossmultiply.
3•11 = 1c
33 = c
The call center will get 33 calls in 11 hours.

Answer:
84
Step-by-step explanation:
f(x) = 3x^2 + 2x – 1
Let x=5
f(5) = 3(5)^2+2(5) -1
= 3*25 +10-1
= 75+10 -1
= 85 -1
= 4⁰×-⁹
= 4⁰
= -4⁹ײ
= -4¹⁸
=( -4)¹⁸
= 4-³ × -³
= 4⁹
= 4⁶ × -³
= 4-¹⁸
= 1/4¹⁸
