Answer:
f(g(2))=84
Step-by-step explanation:
Step one:
Given data
f(x)= x*2 +3
g(x) = 4x + 1
Step two
Let us find g(2) first then we proceed to find f(g(2))
g(2)=4(2) +1
g(2)=8+1
g(2)=9
Since g(2)=9
f(g(2))=x*2 +3
f(g(2))=9*2 +3
f(g(2))=81+3
f(g(2))=84
Answer:
x=-3.875
y=1.625
x+y=5.5
Step-by-step explanation:
Given:
9(1-x)=27y
x-y=-11/2
then:
x=y-11/2 OR 5.5
substitute:
9(1-[y-5.5])=27y
9-9[y-5.5]=27y
9-9y+49.5=27y
simplifying:
36y=58.5
y=1.625
x=1.625-5.5=-3.875
Proof:
x-y=5.5 then -3.875-1.625=-5.5 =-11/2
9(1-x)=27y then 9(1-(-3.875))=27(1.625) then simplified
9(4.875)=43.875 or 43.875=43.875

Answer
67
Step-by-step explanation
66, 51, 77, 68, 60, 75, 54, 80
rearrange the numbers
51, 54, 60, 66, 68, 75, 77, 80
66 and 68 are middle numbers so add it and divide by 2
66+68/2
134/2
=67

Answer:
X = 1.2
Step-by-step explanation:
-2(3x + 7) = -2(1 + 8x)
-6x - 14 = -2 - 16x
+16x +16x
10x - 14 = -2
+14 +14
10x = 12
10 = 10 = 1.2
(x = 1.2)
Answer:
1
Step-by-step explanation:
74/2 = 37/x so u have to cross multipy these two so 74*x = 2*37
then 74x =74 so x=74/74 which is 1 :)
There are 24 minutes in 40 percent of an hour.
The percentage is defined as a ratio expressed as a fraction of 100.
For example, If Misha obtained a score of 67% on her exam, that corresponds to 67 out of 100. It is expressed as 67/100 in fractional form and as 67:100 in ratio form.
We know that there are 60 minutes in one hour
So 1 hour = 60 minutes,
We have to evaluate 40 percent of an hour
⇒ 40% of 1 hour
⇒ 40% of 60 minutes
⇒ 0.4 × 60 minutes
Apply the multiplication operation, and we get
⇒ 24 minutes
There are 24 minutes in 40 percent of an hour.
