Answer:
a=b/4
Step-by-step explanation:
subtract 4b from both sides to end up with a=b-3a and then add 3a to both sides to get 4a=b, and divide both sides by 4 to get a=b/4.
Answer:
a + 4b + 5b - 3a can only be solved by a little.
Step-by-step explanation:
a + 3a =3a.
4b + 5b = 9b.
we can't solve 9b - 3a, since they have different functions, so 9b - 3a is the answer.

A tablet computer costs $356. Inez has saved $140 and hopes to save $12 per week until she can purchase a tablet computer. Which equation can be used to find the number of weeks, w, until Inez can purchase the tablet computer?
Answer:
D
12w + 140 = 356
Step-by-step explanation:
Her goal is to save up 356$. She already has 140$, and wants to save 12$ per week. We're trying to find how many weeks it would take.
You must multiply 12 by the number of weeks, which elimates the first two equations. We're also trying to add together 140 and the 12x because we want the total to ADD to 156.
Hopefully this makes sense, and ask any remaining questions about this in the comments. If you liked my explaination, feel free to give a Brainliest :P

In a recent survey of favorite sodas 7 students chose coke. If these students represent 17.5% of the students surveyed, how many students were surveyed in all?
Answer:
40
Step-by-step explanation:
7 = 17.5% × Y
STEP 2 7 =
17.5
100
× Y
Multiplying both sides by 100 and dividing both sides of the equation by 17.5 we will arrive at:
STEP 3 Y = 7 ×
100
17.5
STEP 4 Y = 7 × 100 ÷ 17.5
STEP 5 Y = 40

Answer:
C
Step-by-step explanation:
Consider functions fand g.
f(x) = -13
g(x) = |1/8x-1|
Answer:
We conclude that
(g o f) (4) = 9
Hence, option C is correct.
Step-by-step explanation:
Given
f(x) = -x³
g(x) = |1/8x - 1|
To determine
(g o f) (4) = ?
Using the formula
(g o f) (4) = g[(f(4)]
first we need to determine f(4)
so substituting x = 4 into f(x) = -x³
f(x) = -x³
f(4) = -(4)³ = -64
so
(g o f) (4) = g[(f(4)] = g(-64)
so substitute x = -64 in g(x) = |1/8x - 1|
[tex]g\left(x\right)=\left|\frac{1}{8}x-1\right|[/tex]
substitute x = -64
[tex]g\left(-64\right)=\left|\frac{1}{8}\left(-64\right)-1\right|[/tex]
[tex]=\left|-\frac{1}{8}\cdot \:64-1\right|[/tex]
[tex]=\left|-8-1\right|[/tex]
[tex]=\left|-9\right|[/tex]
Apply absolute rule: |-a| = a
[tex]=9[/tex]
Therefore, we conclude that
(g o f) (4) = 9
Hence, option C is correct.

from the height of a wall if a ladder 10 metre long place along the wall and its foot is 2 metre away from the wall.
Answer:
height of the wall = 9.79 m
Step-by-step explanation:
This form a right angled triangle.
Hypotenuse = length of the ladder = 10 m
Base = length from foot of ladder to wall.
Altitude = height of the wall
Pythagorean's theorem,
base² + altitude² = hypotenuse²
2² + altitude² = 10²
4 + altitude² = 100
altitude² = 100 - 4
altitude² = 96
altitude = √96 = 9.79 m
Find the area of the triangle.
Answer:
its 10k

Jason and Monica each need to put 1 gallon of water into a pot.Jason has a measuring cup that holds 1 cup.Monica has a measuring cup that holds 1 pint. How many more times does Jason need fill the measuring cup than Monica?
Answer:
8 more times than
Step-by-step explanation:
We are told in the above question that:
Jason and Monica each need to put 1 gallon of water into a pot.
It is important to note that:
1 liquid gallon = 16 cups
1 liquid gallon = 8 liquid pints
For Jason
Jason has a measuring cup that holds 1 cup.
1 liquid gallon = 16 cups
In order to fill the pot, Jason has to use the cup 16 times
For Monica
Monica has a measuring cup that holds 1 pint.
Monica has to fill the pot using her measuring cup 8 times
How many more times does Jason need fill the measuring cup than Monica?
This is calculated as:
16 times - 8 times
= 8 times
Therefore, Jason needs to fill the measuring cup 8 more times than Monica

If y = 8 when x
8 when x = 3, find y when x = 45.
Answer:
y = 120
Step-by-step explanation:
y = kx ur finding k
8 = k 3 get k alone by dividing both sides by 3 --> 8/3 = k
k = 8/3
Y = 8/3 45 now your finding Y when x is 45
Y = 120
to make sure do 120 = 8/3 45 should equal the same

Jorge pays $13 per month to join the track club. He pays $6.00 every time he rents a discus. The equation C = 13m 4- 6.00n. Represents the total cost of throwing at the club, where m is the number of months, and n is the number of practice sessions. What is the total cost per year for Jorge to go to the club 20 times?
Complete question :
Jorge pays $13 per month to join the track club. He pays $6.00 every time he rents a discus. The equation C = 13m + 6.00n. Represents the total cost of throwing at the club, where m is the number of months, and n is the number of practice sessions. What is the total cost per year for Jorge to go to the club 20
The 4- in the equation seems to be a typographical error and instead should have been something like this :
C = 13m + 6.00n
Answer:
$276
Step-by-step explanation:
Given :
Cost of throwing, C = 13m - 6n
m = Number of months ; n = number of practice sessions
n = 20 ; m = 1 year = 12 months
C = 13(12) + 6(20)
C = 156 + 120
C = $276
