Answer:
x= −47/18
Step-by-step explanation:
Step 1. solve inside the parenthesis and distribute the 9
72+2=−18x+27
(72+2)=−18x+27(Combine Like Terms)
74=−18x+27
Step 2: Flip the equation.
−18x+27=74
Step 3: Subtract 27 from both sides.
−18x+27−27=74−27
−18x=47
Step 4: Divide both sides by -18.
x= −47/18
In March, Terell weighed 104 1/3 pounds.
In June, he weighed 109 1/2 pounds.
How much weight did Terell gain
between March and June?
Answer:
Terell gained 5 and 1/6 pounds between March and June
Step-by-step explanation:
1. 109 - 104 = 5
2. Convert 1/3
1/3 = 2/6
3. Convert 1/2
1/2 = 3/6
4. Subtract them
3/6 - 2/6 = 1/6
(Full equation: 109 and 1/2 - 104 and 1/3 = 5 and 1/6 pounds)

how do you solve it and how do you explain?
Answer:
so the answer is 30
now to find the answer we just need to do this...
step 1: we need to simplify the equations from both sides.
[tex]\frac{-2}{5} x = -12[/tex]
then we multiply on both sides by [tex]\frac{5}{-2}[/tex]
[tex](\frac{5}{-2}) *(\frac{-2}{5}x )= (\frac{5}{-2} )*(-12)[/tex]
which equals x= 30

5x^2-22x+8=0
can you find the roots?
Step-by-step explanation:
Answer:
x = [tex]\frac{2}{5}[/tex], x = 4
Step-by-step explanation:
Given
5x² - 22x + 8 = 0
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 5 × 8 = + 40 and sum = - 22
The factors are - 20 and - 2
Use these factors to split the x- term
5x² - 20x - 2x + 8 = 0 ( factor the first/second and third/fourth terms )
5x(x - 4) - 2(x - 4) = 0 ← factor out (x - 4) from each term
(x - 4)(5x - 2) = 0
Equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
5x - 2 = 0 ⇒ 5x = 2 ⇒ x = [tex]\frac{2}{5}[/tex]

Answer: -16/3
Step-by-step explanation:
-2 (8/3)
(-2/1)(8/3)
((-2)(8))=-16
1(3)=3
-16/3
Answer:
-2 x 8/3 = -16/3
Step-by-step explanation:
When multiplying fractions, you multiply the numerators (numbers above the fraction line) and the denominators (numbers below the fraction line) with each other. If one of the numbers is not visibly a fraction, remember that all numbers are actually fractions - you must simply write in the denominator of 1. In this case, you'd write [tex]-\frac{2}{1} * \frac{8}{3}[/tex], which would then give you the result of [tex]-\frac{16}{3}[/tex] (-2 x 8 = -16, 1 x 3 = 3).

Maddie, Jaeahna, Chelsea and Onella swam in the relay for Colyton at district . If the complete lap times added to 137.009 seconds. What was the average lap time for each swimmer?
Answer:
34.25 seconds
Step-by-step explanation:
Given that :
Summation of the complete lap time of each of the four swimmers = 137.009 seconds
The average lap time for each of the four swimmers will be :
The average of the total lap time ;
Total lap time / number of swimmers
= 137.009 / 4
= 34.25225 seconds
Hence, each swimmer has an average lap time of 34.25 seconds

Which ordered pair is a solution to the system of equations?
y=4x
y= 3x + 2
The solution of the system of equations will be (2, 8).
What is substitution method?
To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.
Given that;
The system of equations are,
y = 4x
And, y = 3x + 2
Now,
Solve the linear equations as;
The system of equations are,
y = 4x .... (i)
y = 3x + 2 .. (ii)
Substitute y = 4x in equation (ii) as;
y = 3x + 2
4x = 3x + 2
4x - 3x = 2
x = 2
And, y = 4x
y = 4 × 2
y = 8
Thus, The solution of the system of equations will be (2, 8).

John is 4 years younger than twice Michael's age. Michael is John's younger brother. John is 18 years old. How old is Michael? Choose the equation that represents the situation.
Answer:
18=2m-4
Step-by-step explanation:
18 is the age of John. M represents the age of Michael. John is older than Michael so instead of 18=4-2m it is 18=2m-4. If you do 8=4-2m it will be inccorect because it will give you a negative. Michael is 11 years old.
The cost of 24 caps is $150. Find the cost of each cap.
Answer:
6.25
Step-by-step explanation:
Divide 150 $ to 24 caps on your calculator
If the cost of 24 caps is $150, then the cost of each cap is $6.25.
What is unitary method?We know that a single unit's value can be determined from the values of multiple units, and multiple units' values can be determined from the values of single units using the unitary method. We typically use this technique for math calculations. We are able to locate the missing value using the unitary method.
How to solve it?Given that the cost of 24 caps is $150.
Then the cost of 1 cap is 150/24 = $6.25
Therefore we can conclude that If the cost of 24 caps is $150, then the cost of each cap is $6.25.

Two ice cream shops in the mall sell sundaes. Let x equal the number of scoops of ice cream. Larry's Ice Cream Shop's price is represented by the expression 1.2x + 1. Ice Cream World's price is represented by the expression 0.4(0.3x + 1) . Which statement is true?
Choose the correct answer below.
A.
The two shops charge the same price for a 3-scoop sundae.
B.
The two shops charge the same price for a 2-scoop sundae.
C.
The two shops never charge the same price for sundaes with the same number of scoops.
D.
The two shops always charge the same price for sundaes with the same number of scoops.
Answer:
the answer is D.
Step-by-step explanation:
this is because if you distribute 0.4 times 0.3 you get 0.12.

A car salesman gets paid $3,750 each month plus 8.5% commission on his total sales. This month he sold 5 cars for a total of $138,000. What are his monthly total earnings?
The car salesman total earnings if he sold 5 cars for a total of $138,000 is $15480.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
A variable can either be dependent or independent. A dependent variable depend on other variable while an independent variable does not depend on other variables.
Let y represent the total money the salesman earns for selling a total of $x sales. Hence:
y = 0.085x + 3750
If the salesman makes a total of $138000, hence:
y = 0.085(138000) + 3750
y = 15480
The car salesman total earnings if he sold 5 cars for a total of $138,000 is $15480.
