Amanda increased the amount of protein she eats every day from 48g to 54g. By what percentage did Amanda increase the amount of protein she eats?
Answer:
Explanation:
The formula for calculating the percent change is:
p=N−OO⋅100
Where:
p is the percent change - what we are looking for
N is the New Value - 54g for this problem
O is the Old Value - 48g for this problem
Substituting and calculating p gives:
p=54−4848⋅100
p=648⋅100
p=60048
p=12.5

In 2000 jonesville had a population of 15,000. In 2001 the population was 16,250 and in 2002 the population was 17,500 in the population grew at the same constant rate each year which model describes the population growth for n years after 2000?
Answer:
15000+1250x
Step-by-step explanation:
Since the initial population is 15,000, we want to know how many people are going to Jonesville each year. Assuming that in 2001 and in 2002, each year adds 1,250 people and that it is constant. The equation is 15000+1250x in which 15,000 represents the initial number and 1250 is the amount of people added each year followed by x which is the number in years.
x/-9 =3
I dont understand this.
Answer:
x = -27
Step-by-step explanation:
x / 9 =3
multiply both sides by -9
x = -27
Hope this helps!!
Happy Holidays!!
Final Answer: [tex]x = -27[/tex]
Steps/Equations:
Question: [tex]\frac{x}{-9} = 3[/tex]
Step 1: Move the negative sign to the left side.
[tex]-\frac{x}{9} = 3[/tex]
Step 2: Multiply both sides by [tex]3[/tex].
[tex]-x = 3 * 9[/tex]
Step 3: Simplify [tex]3 * 9[/tex] to [tex]27[/tex].
[tex]-x = 27[/tex]
Step 4: Multiply both sides by [tex]-1[/tex].
[tex]x = -27[/tex]

Tannis’s first machine could throw a car 27 meters. She stufied her first machine and built a better one. her second machine could throw a car 7 times as far. How far does the second machine throw a car?
The second machine is capable of throwing a car a distance of 189 meters. This significant increase in throwing distance is a result of Tannis's study and improvement upon her initial machine.
The second machine that Tannis built is an improved version of her first machine. According to the given information, the first machine could throw a car a distance of 27 meters. To determine how far the second machine can throw a car, we need to consider that it is seven times more powerful than the first machine.
If the first machine's distance is multiplied by seven, we get:
27 meters * 7 = 189 meters.
Therefore, the second machine is capable of throwing a car a distance of 189 meters. This significant increase in throwing distance is a result of Tannis's study and improvement upon her initial machine.

what’s x?
Answer: x equals forty one over five
Step-by-step explanation: Add the numbers 18x-15+3x-11+4x+1=180 18x-25+3x+4x=180 then you combine like terms and you get, 18x-25+3x+4x=180 25x-25=180 then you add 5 to both sides of the equation 25x-25=180. 25x-25+25=180+25 then you simplify then you add the numbers 25x=205 then you divide both sides of the equation by the same term 25x=205 25x/25 = 205/25 then you simplify, you cancel terms that are in both the numerator and denominator then you divide the numbers and you get, x equals forty one over five.

) A fraction becomes 4
5
if 1 is added to both numerator and denominator.
If, however, 5 is subtracted from both numerator and denominator, the fraction becomes 1by2
.
Answer:
?????????????????????????
Answer:
original fraction = [tex]\frac{7}{9}[/tex]
Step-by-step explanation:
let x be the numerator and y be the denominator of the original fraction, then
[tex]\frac{x+1}{y+1}[/tex] = [tex]\frac{4}{5}[/tex] ( cross- multiply )
5(x + 1) = 4(y + 1) ← distribute parenthesis on both sides
5x + 5 = 4y + 4 ( subtract 4y from both sides )
5x - 4y + 5 = 4 ( subtract 5 from both sides )
5x - 4y = - 1 → (1)
Also
[tex]\frac{x-5}{y-5}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
2(x - 5) = y - 5
2x - 10 = y - 5 ( subtract y from both sides )
2x - y - 10 = - 5 ( add 10 to both sides )
2x - y = 5 → (2)
Solve the 2 equations simultaneously for x and y
Multiply (2) by - 4
- 8x + 4y = - 20 → (3)
Add (1) and (3) term by term to eliminate y , that is
- 3x = - 21 ( divide both sides by - 3 )
x = 7
Substitute x = 7 into either of the 2 equations and solve for y
Substituting into (1)
5(7) - 4y = - 1
35 - 4y = - 1 ( subtract 35 from both sides )
- 4y = - 36 ( divide both sides by - 4 )
y = 9
Thus the original fraction = [tex]\frac{7}{9}[/tex]
