A. x = 37
B. x = 6
C. 37x = 6
D. 376x=37
E. 112x+23x=37
Using operations with fractions, it is found that the possible steps are:
B. [tex]x = 6[/tex].D. [tex]\frac{37x}{6} = 37[/tex]E. [tex]\frac{11}{2}x + \frac{2}{3}x = 37[/tex]The equation given is:
[tex]5\frac{1}{2}x + \frac{2}{3}x = 37[/tex]
The improper fraction can be written as:
[tex]5\frac{1}{2} = \frac{5\times 1 + 2}{2} = \frac{11}{2}[/tex]
Then:
[tex]\frac{11}{2}x + \frac{2}{3}x = 37[/tex]
Applying the least common multiple:
[tex]\frac{33x + 4x}{6} = 37[/tex]
[tex]\frac{37x}{6} = 37[/tex]
[tex]37x = 37 \times 6[/tex]
[tex]x = \frac{37 \times 6}{37}[/tex]
[tex]x = 6[/tex]
Hence, options B, D and E are correct.

Answer:
5 cups
Step-by-step explanation:
hi! to find the sum of the soup mix, we have to add all the fractions together.
7/4 + 1/2 + 5/3 + 1/3 +1/4 + 1/2
we have to find a common denominator for each, which is the LCM of the denominators. this would be 12. let's change the fractions so we can add them up.
21/12 + 6/12 + 20/12 + 4/12 + 3/12 + 6/12
add the numerators and keep the denominators the same.
(21+6+20+4+3+6)/12
60/12
this simplifies to 5.
the total amount of soup mix is 5 cups.
Answer:
5 cups of soup mix
Step-by-step explanation:
Make all the denominators equal. The lowest common denominator is 12 so multiple the denominators with 4 by 3, 2 by 6, and 3 by 4.
[tex]\frac{7}{4} *3=\frac{21}{12}[/tex]
[tex]\frac{1}{2} *6=\frac{6}{12}[/tex]
[tex]\frac{5}{3} *4=\frac{20}{12}[/tex]
[tex]\frac{1}{3} *4=\frac{4}{12}[/tex]
[tex]\frac{1}{4} *3=\frac{3}{12}[/tex]
[tex]\frac{1}{2} *6=\frac{6}{12}[/tex]
Now that all the fractions have the same denominator you can add them all together.
[tex]\frac{21}{12} +\frac{6}{12} +\frac{20}{12} +\frac{4}{12} +\frac{3}{12} +\frac{6}{12}=\frac{60}{12}[/tex]
Then simplify the fraction to find out how many total cups of soup mix you have.
[tex]\frac{60}{12} =5[/tex]
5 cups of soup mix

For each of these problems, remember SOH-CAH-TOA.
Sine = opposite/hypotenuse
Cosine = adjacent/hypotenuse
Tangent = opposite/adjacent
5) Here we are looking for the cosine of the 30 degree angle. Cosine uses the adjacent side to the angle over the hypotenuse. Therefore, cos(30) = 43/50.
6) We have an unknown side length, of which is adjacent to 22 degrees, and the length of the hypotenuse. Since we know the adjacent side and the hypotenuse, we should use Cosine. Therefore, our equation to find the missing side length is cos(22) = x / 15.
7) When finding an angle, we always use the inverse of the trigonometry function we originally used. Therefore, if sin(A) = 12/15, then the inverse of that would be sin^-1 (12/15) = A.
8) We are again using an inverse trigonometry function here. We know the hypotenuse, as well as the side adjacent to the angle. Therefore, we should use the inverse cosine function. Using the inverse cosine function gives us cos^-1 (9/13) = 46 degrees.

If cat food is sold in 20 lb bags, what is the least number of bags of cat food needed for one year at this shelter, if 10 lbs of cat food is consumed per week?
Answer:
26 weeks!
Step-by-step explanation:
Hello there!
There are 52 weeks in a year, believe it or not! So, if 1 bag of food was 10 lbs, then it would be 1 bag of 10lbs x 52 weeks, so it would be 52 bags. However, we are dealing with 20 lb bags, which will last twice as long as the 10 lb bag! So, if 1 bag will last 2 weeks, and there are 52 weeks in a year, then it is weeks divided by number of weeks it takes to consume 1 bag, 52 divided by 2. 52 divided by 2 is 26.
So in 1 year, the shelter will need 26 bags of 20 lb cat food!
Hope I helped!

Step-by-step explanation:
hi! if the leading term is 8x^9, this means that this is the term with the highest power. therefore, its degree is 9.
The degree of the given polynomial is 9
What is a polynomial expression?Polynomial is made up of two terms, namely Poly (meaning “many”) and Nominal (meaning “terms.”). A polynomial is an expression composed of variables, constants, and exponents, combined using mathematical operations such as addition, subtraction, multiplication, and division (No division operation by a variable). Based on the number of terms present in the expression, it is classified as monomial, binomial, and trinomial. For example P(x) = x2-5x+11
Given here; a polynomial function with leading term 8x⁹
Now The Degree of a Polynomial is the largest of the degrees of the individual terms. The degree of an individual term of a polynomial is the exponent of its variable and the highest degree of the terms given in the expression is the degree. And thus the expression with leading term 8x⁹ is 9
Hence, The degree of the given polynomial is 9

A truckload of plastic soda bottles was finely shredded at a recycling center. The plastic shreds were placed into 55-liter drums. What it the mass of the plastic shreds inside one of the drums in kg? Assume lowest density within the range.
Answer:
75,900 g
Step-by-step explanation:
m=d×v
(1.38g/cm^3) × (55,000)
The mass of the drum is 75.9 kg.
What is the mass of the drum?The mass of the drum is the product of the volume and density of the drum.
What are Arithmetic operations?Arithmetic operations can also be specified by the addition, subtract, divide, and multiply built-in functions.
+ Addition operation: Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
We have been given that the plastic shreds were placed into 55-liter drums.
We have to determine the mass of the plastic shreds inside one of the drums in kg.
Here density of the drum = 1.38g/cm³ and the volume of the drum = 55,000
The mass of the drum = (1.38g/cm³) × (55,000)
The mass of the drum = 75,900 g
The mass of the drum = 75.9 kg

A. The value of (4) is 20, and it represents the number of hours of work remaining for the month after working for 4 days.
B. The value of ? (4) is 20, and it represents the number of hours spent working over 4 days
C. The value of }(4) is 60, and it represents the number of hours of work remaining for the month after working for 4 days
D. The value of (4) is 60, and it represents the number of hours spent working over 4 days.
**pls help ASAP taking a test .
Answer:
C. The value of f (4) is 60, and it represents the number of hours of work remaining for the month after working for 4 days
Step-by-step explanation:
So 5 time 4 equals 20...!
80 minus 20= 60
The value of f (4) is 60, and it represents the number of hours of work remaining for the month after working for 4 days, which is the correct answer would be option (C).
What is a numerical expression?A numerical expression is algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.
A student works 80 hours per month and plans to work 5 hours each day, but only on days when work is planned. After working for d days, the function / (d) - 80 — 5d shows the number of hours of work remaining for the month.
⇒ f (d) = 80 - 5d ....(i)
According to option (C),
Substitute the value of d = 4 in equation (i),
⇒ f (4) = 80 - 5(4)
⇒ f (4) = 80 - 20
⇒ f (4) = 60
Thus, the value of f (4) is 60, and it represents the number of hours of work remaining for the month after working for 4 days

3(x – 10) = -9
Answer:
The answer is x = 7
Step-by-step explanation:
Divide each term by 3 and simplify. Move all terms not containing x to the right side of the equation.
Answer:
[tex]\huge\boxed{x=7}[/tex]
Step-by-step explanation:
In order to solve for x, our goal is to isolate it on one side of the equation. We can do this by reversing the equation.
Let's apply the distributive property on the left side:
[tex](3 \cdot x) + (3 \cdot -10) = -9\\\\3x-30=-9[/tex]
Add 30 to both sides:
[tex]3x - 30 + 30 = -9 + 30\\\\3x = 21[/tex]
Divide both sides by 3:
[tex]3x \div 3 = 21 \div 3\\\\x = 7[/tex]
So x = 7.
