Answer:
infinite solutions
Step-by-step explanation:
-3f + 3f = 0
0=0
This is always true so there are infinite solutions
Answer:
All Real Numbers (infinite Solutions)
Step-by-step explanation:
When you cancel out the -3f and the +3f you get [tex]0=0[/tex] and since that is true you get all real numbers

If you have 9/10 of a pound of granola how many 1/5 pound bags can you fill ?
Answer:
4
Step-by-step explanation:
1/5 is the same as 2/10. How many 2's can you put in 9? You can put 4.5 2's in a 9. However, filling half a bag does not fill the entire bag, so the answer would be 4. You can fill 4 full 1/5 pound bags with 9/10 pounds of granola.
Ericka is also in Mr. Whittaker’s science class and she recorded the variation in water level at a different part of the river. She observed that the water level there fell 2.2 millimeters per year over a period of 6.2 years This data is compared to the average annual trend, which shows the water level rising 1.8 mm/year. Which of the decimals in the problem should be represented as a negative rate? Which two factors should Ericka multiply to find the total variation in water level?
Answer:
first one is 2.2mm/year and second is 6.2years and -2.2mm/year
Step-by-step explanation:
plz trust me i just did it
The decimals in the problem should be represented as a negative rate is -2.2mm/year

Chase was asked to simplify the expression (-3) ^ 4 * (-3) ^ 9 equals is shown was work below do you agree or disagree with Chase's War explain your reasoning chases work (-3) to the power of 4 * (-3) ^ 9 equals (-3) ^ 36
Answer:
Step-by-step explanation:
Given the expression chase was asked to simplify as [tex](-3) ^ 4 * (-3) ^ 9[/tex], lets first solve and compare our solution with chases's
Using the law of indices [tex](a) ^ m * (a) ^ n = a^{m+n}[/tex]
[tex]= (-3) ^ 4 * (-3) ^ 9 \\\\= (-3)^{4+9}\\\\= (-3)^{13}[/tex]
Chases reasoning is wrong according to his answer [tex](-3) ^ 4 * (-3) ^ 9 = (-3)^ {36}[/tex]. What chase's did was to multiply the power of -3 together instead of adding. In indices when the bases are equal and we are multiplying, the powers of the bases will be added not multiplies=d as chase's did.

Answer:
g= −6/13o5
Step-by-step explanation:
Let's solve for g.
−3−(−8)−(−2)=x0−13ogo3o
Step 1: Flip the equation.
−13go5+1=7
Step 2: Add -1 to both sides.
−13go5+1+−1=7+−1
−13go5=6
Step 3: Divide both sides by -13o^5.
−13go5
−13o5
=6−13o5
g=−6/13o5

To convert from feet to inches, we multiply by 12. For example, the number of inches in 2 feet is 12(2) inches.
If one board has length of (x+3) feet and a second board had a length of (2x-3) inches, express their total length in inches as an algebraic expression
Answer:
L = (14x+33) inches.
Step-by-step explanation:
We know that,
1 feet = 12 inches
For example,
2 feet = 12(2) inches
Now, the length of one board is (x+3) feet
The length of second board is (2x-3) inches
We can convert length into inches as follows :
l = (x+3) feet
l= (x+3)(12) inches
l = 12x+36 inches
It means, total length,
L = 12x+36 inches + (2x-3) inches
L = (14x+33) inches.

6(m - 1) = 3(3m + 2)What to do?
We have to solve for m[tex].[/tex]Solution:
The equation has only one variable i.e. m. For finding m we need to isolate it any one side of the equation. Before that, let's expand the parentheses,
⇒ 6(m - 1) = 3(3m + 2)
⇒ 6m - 6 = 9m + 6
Now moving m to the left hand side and constant terms to the right hand side,
⇒ 6m - 9m = 6 + 6
⇒ -3m = 12
Dividing the Equation by -3,
⇒ m = 12 / -3
⇒ m = -4
Thus, the required value of m is -4.
A Chinese restaurant has the family special shown at right. What is the original average cost of the entrees if the discount is 52 per entree? ANY FOUR ENTREES FOR $20
This question was not written properly
Complete Question
A Chinese restaurant has the family special shown at right. What is the original average cost of the entrees if the discount is $2 per entree? ANY FOUR ENTREES FOR $20
Answer:
$7
Step-by-step explanation:
From the question we are told that :
Any 4 entrees = $20,
And there is a discount of $2 per entree.
Let us represent the original average cost of entrees as = a
Hence, we have the algebraic expression
4(a - 2) = 20
4a - 8 = 20
4a = 20 + 8
4a = 28
Divide both sides by 4
4a/4 = 28/4
a = 7
Therefore, the original average cost of the entrees if the discount is $2 per entree is $7.
Find the sum of the series.
[infinity] ln(1 − 1/n2) n = 2
Answer:
The sum is -1/2
Step-by-step explanation:
Your question is not too clear to me but if I reframe it, it will turn to this;
Find the sum of In{1 - (1/n^2)} for n >= 2
£n>=2 = In{1 - (1/2^2)} + In{1 - (1/3^2)} + In{1 - (1/4^2)} + ......
£n>=2 = In{1 - (1/4)} + In{1 - (1/9)} + In{1 - (1/16)}
£n>=2 = In(3/4) + In(8/9) + In(15/16)
£n>=2 = -0.287 + -0.117 + -.064 = −0.468
£n>=2 = -0.5 by approximation
£n>=2 = -1/2 is the sum and by evaluation it converge.

Bill Granger is a parts clerk. He worked a total of 46.25 hours from Monday to Friday this week. If his regular pay is $12.75 per hour, how much overtime pay did Bill earn?
Answer:
His extra pay would be of $79.69
