4.05 in a mixed number is 4 1/2
2 ways: Easy and hard
Hard=A
Easy=B
A: 1/2x+4
work from there so we do fun stuff with it
make something that can be simplified so
1/2x+4 times (2/2)=x+8
now square the whole thing and put the result in a square root thingie
(x+8)^2=x^2+16x+64

multiply the whole thing by 4/4 and put
![\sqrt{16} [\tex] on top so then [tex] \sqrt{x^2+16x+64}](https://tex.z-dn.net/?f=%20%5Csqrt%7B16%7D%20%5B%5Ctex%5D%20on%20top%20so%20then%20%0A%5Btex%5D%20%5Csqrt%7Bx%5E2%2B16x%2B64%7D%20)
times

=

=

to solve it, factor out the 16 in the square root and then square root 16 to get 4
then it will be (4 times square root of equation)/4=square root of equatio
factor square root of equation and square root it and get x+8
divide by 2 to get 1/2x+4
B: 1/2x+4
put stuff that cancels out
1/2x+3x-3x+4+56-56
move them around
3 and 1/2x-3x+60-56
or
2x-3x+1 and 1/2x+30-20+30-36
then just add like terms to solve
Answer:
<em>T </em><em>=</em><em> </em><em>1</em><em>6</em>
Step-by-step explanation:
As triangles are similar
AB/DE = BC/EF = AC/DF
13.5/18 = 6/4 = 12/T
3/4 = 3/4 = 12/T
3/4 = 12/T
T = 12×4/3
T = 16
Answer:
216 gallon
Step-by-step explanation:
We are given that
Milk in gallon probability week
200 3/30 3
205 4/30 4
210 6/30 6
215 5/30 5
220 4/30 4
225 3/30 3
230 2/30 2
235 2/30 2
240 1/30 1
Total weeks=30
We have to find the average number of gallons of milk consumed per week
The average number of gallons of milk consumed per week
=Total number of gallons of milk/total weeks
Using the formula
The average number of gallons of milk consumed per week
=
=
=
gallons/week
Hence, the average number of gallons of milk consumed per week= 216 gallon
Answer:The maximum number of visits a member of the history museum can make for a total cost of $40 is 17
Step-by-step explanation:
Let x represent the number if visits that visits the person makes to the museum.
Let y represent the cost of x visits
A person can pay $6 for a membership to the history museum and then go to the museum for just $2 per visit. It means that the total cost, y for x visits will be
y = 2x + 6
For a total cost of $40, y = 40. So
40 = 2x + 6
2x = 40 - 6
2x = 34
x = 34/2 = 17
