Miles that alex can drive is 100
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.
The calculation is as follows;
Number of days alex rents a car = 1 day
The charge for the car = $18 plus $0.12 per mile
Alex wants to spend; $30
The number of miles he will drive can be calculated as follows
= $30 - $18
= $12
= 12÷0.12
= 100
Therefore, if Alex spends $30 he will drive for 100 miles

find the smallest number by which 339 must be multiplied so that the product is a perfect cube. also find the cube root of the perfect cube so obtained
Answer:
The smallest number is 114921 and the cube root of the result is 339
Step-by-step explanation:
The number 339 can be factored as:
339 = 3 * 113
Both factors are prime, thus to produce a perfect cube, we must multiply by each factor to the power of 2, that is:
3^2*113^2=114921
When we multiply 339 by 114921 we get 38958219, a perfect cube which cube root is 339.
Thus, the smallest number is 114921 and the cube root of the result is 339

I'm confused on this problem 2/3x-1=5
Answer:
x=9
Step-by-step explanation:
2/3x-1=5
Add 1 to each side
2/3x-1+1= 5+1
2/3x = 6
Multiply each side by 3/2
2/3x*3/2 = 6*3/2
x = 9
Answer:
x=9
Step-by-step explanation:
You add one to both sides, multiply 3 to both sides (to further isolate x), and then divide by 2 on both sides. When you substitute back in, both sides of the equation are equal to each other.

Determine if the two fraction are equivalent, 65/4, 13/2
Answer:
The fractions are not equivalent. If you cross multiply 65 x 2 = 130 and 4 x 13 = 52. 130 > 52. Set them as a proportion. [tex]\frac{65}{4} = \frac{13}{2}[/tex]
They are not equal.
For 65/4 you cannot divide it by 2 and then get 13/2. You would get 32.5/2.
32.5/2 is not equal to 13/2

what is the value of n for the equation 1/3n=9
Answer: n = 27
Step-by-step explanation: n in (-oo:+oo)
(1/3)*n = 9 // - 9
(1/3)*n-9 = 0
1/3*n-9 = 0 // + 9
1/3*n = 9 // : 1/3
n = 9/1/3

Gregoria borrowed $2,450, to be paid back at 3.5% simple interest. She spent $3221.75 in all to repay the loan. How many years did Georgia take to repay the loan?
Answer: 9 years
Step-by-step explanation:
Simple interest = PRT/100
where
P = principal = $2450
R = rate = 3.5%
T = time = unknown
Interest = $3221.75 - $2450 = $771.75
Simple interest = PRT/100
$771.5 = ($2450 × 3.5 × T)/100
$771.5 = $8575T/100
8575T = 771.5 × 100
8575T = 77150
T = 77150/8575
Time = 8.99 years = 9 years
solve -8(n+5)=-44-8n
Answer:
there are no solutions
Step-by-step explanation:
HERE ARE THE STEPS IN CASE U NEED EM :)
Step 1: Simplify both sides of the equation.
−8(n+5)=−44−8n
(−8)(n)+(−8)(5)=−44+−8n(Distribute)
−8n+−40=−44+−8n
−8n−40=−8n−44
Step 2: Add 8n to both sides.
−8n−40+8n=−8n−44+8n
−40=−44
Step 3: Add 40 to both sides.
−40+40=−44+40
0=−4

Find the measure of this angle, and explain your answer.
Answer:
50
Step-by-step explanation:
180 - 90+40 = 50
Answer:
Answer: 50 degrees
Step-by-step explanation:
important things to know:the square in the bottom right means 90°all angles in a triangle add up to 180°using this knowledge, you can make the following equation:
90 + 40 + x = 180
130 + x = 180
now subtract 130 from both sides.
x = 180 - 130
x = 50°

What products are defined for these matrices?
Drag the operation to the boxes to correctly complete the table.
Answer:
Product is defined [tex]{}[/tex]
(ML, MP, NM, PQ, PL, LP, MQ, LQ)
Product is not defined
(LM, PM, MN, QP, QM, NQ, QN, NL, LN, NP, PN, QL)
Step-by-step explanation:
During multiplication of matrices, the number of columns of the first matrix must be equal to the number of rows of the second matrix it is multiplying.
Therefore, we can only multiply a m×n matrix to a n×c matrix as follows;
We can only multiply (m×n)·(n×c) → Product is defined
We can not multiply (n×c)·(m×n) →∞ Product is not defined.

what is the slope or the line going through (0,0) (6,8) A: -6/8 B: -3/4 C: 3/4 D: 8/6
Start at (0,0). To get to the other point, you must move up 8 units and move to the right 6 units.
slope = rise/run = (change in y)/(change in x) = 8/6
Or you could use the slope formula
m = (y2-y1)/(x2-x1)
m = (8-0)/(6-0)
m = 8/6
Normally I would reduce, but your teacher has decided not to.
8/6 reduces to 4/3 when you divide both parts by 2.
David watches Maria and Alma race electric trains around a track. Maria's train goes around the track in 10 seconds. Alma's train goes around the track in 12 seconds.
How long will it take for both trains to cross the finish line together the first time?
A
30 seconds
B
60 seconds
C
72 seconds
D
120 seconds
Answer:
60 seconds.
Step-by-step explanation:
We have been given that Maria train can go around the track in 10 seconds. Alma train can go around the track in 12 seconds.
To find the number of seconds after which both trains will cross the finish line together the first time we will find LCM of 10 and 12. LCM will give us the smallest positive integer that is divisible by both 10 and 12.
Multiples of 10 are: 10, 20, 30, 40, 50, 60, 70,...
Multiples of 12 are: 12, 24, 36, 48, 60, 72, 84,..
We can see that least common multiple of 10 and 12 is 60, therefore, it will take 60 seconds for both trains to cross the finish line together the first time.
