PLEASE HELP Rob wants to buy a new canoe that will cost $720. How many months will it take him to save enough money to buy it if his cash inflows average about $420 a month and his current cash outflows are $360 a month?
Answer:
12 months
Step-by-step explanation:
if the amount of money rob makes a month is $420 and the amount he spends a month is $360 then subtract the two. if you do this you should get 60 and the you find 60 times what = $720
Rewrite equation in slope intercept form, if necessary. Then determine whether the lines are parallel. Explain. 23. Y = -x + 6 24. Y - 7x = 6 25. 3x + 4y = 12 26. 2x + 5y = -1 x + y = 20 y + 7x = 8 6x + 2 = 6 10y = -4x - 20
Answer:
Step-by-step explanation:
Slope intercept form
[tex]y= mx + c[/tex]
m=slope
c= intercept
1) y= -x + 6
2) y=7x + 6
3) y= -3/4x + + 3
4) y= -2/5x - 1/5
5) y= -x + 20
6) y= -7x + 8
7) y= -3x + 3
8) y= -2/5x -2
Line 1 and 5 are parallel because both have the same slope of -1
line 4 and 8 are also parallel as the their slopes are -2/5
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]

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.

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).

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
x²+x-90=0 using completing the square method
Answer:
x = - 10, x = 9
Step-by-step explanation:
Given
x² + x - 90 = 0 ( add 90 to both sides )
x² + x = 90
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2([tex]\frac{1}{2}[/tex] )x + [tex]\frac{1}{4}[/tex] = 90 + [tex]\frac{1}{4}[/tex]
(x + [tex]\frac{1}{2}[/tex] )² = [tex]\frac{361}{4}[/tex] ( take the square root of both sides )
x + [tex]\frac{1}{2}[/tex] = ± [tex]\sqrt{\frac{361}{4} }[/tex] = ± [tex]\frac{19}{2}[/tex] ( subtract [tex]\frac{1}{2}[/tex] from both sides )
x = - [tex]\frac{1}{2}[/tex] ± [tex]\frac{19}{2}[/tex] , thus
x = - [tex]\frac{1}{2}[/tex] - [tex]\frac{19}{2}[/tex] = [tex]\frac{-20}{2}[/tex] = - 10
x = - [tex]\frac{1}{2}[/tex] + [tex]\frac{19}{2}[/tex] = [tex]\frac{18}{2}[/tex] = 9

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.

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).
