6/10
because if u divide 6 by 2, u get 3
and divide 10 by 2 to get 5
so 6/10 is equivalent

Answer:

6/10

Step-by-step explanation:

6/10 is equal to 3/5 because you can multiply 3/5 times 2. So multiply the numerator(3) times 2, which is 6, then multiply the denominator(5) times 2 as well, which is 10.

Hope this helped!

P.S (in case you don't know the definition of numerator or denominator)

Nominator- the top number of a fraction.

If 6^4x = 82, what is the value of x?
Round your answer to three places.

Answers

Answer:

[tex]x=0.61485921[/tex]

Step-by-step explanation:

The given equation is in exponential form:

[tex]6^{4x} =82[/tex]

To find [tex]x[/tex] we need to write it in logarithmic form:

[tex]b^{a} =n[/tex] ⇒ [tex]log_{b} n=a[/tex]

[tex]6^{4x} =82[/tex] ⇒ [tex]log_{ 6 } 82=4x[/tex]

           [tex]2.45943684 = 4x[/tex]

              [tex]\frac{2.45943684}{4} = x[/tex]

           [tex]0.61485921 =x[/tex]

To prove this, we can substitute the value into the given equation

             [tex]6^{4x} =82[/tex]

[tex]6^{4(0.61485921)} =82[/tex]

               [tex]82=82[/tex]

Therefore, the answer is [tex]x=0.61485921[/tex]

Do not factor by grouping. Solve 2(x-2)^1/3=x+2

Answers

Step-by-step explanation:

2(x-2)⅓=x+2

so we first cube each side,such that...

(2(x-2))⅓•³=(x+2)³

we get...

2(x-2)=(x+2)³

expanding...

2x-4=x³+6x²+12x+8

grouping....

x³+6x²+12x+8-2x+4=0

solving...

x³+6x²+10x+12=0

now you can use you calculator to solve for the possible values of x

The baker's at a bakery can make 160 bagels in 4 hours how many bagesl can they bake in 16 hours? What is that rate per hour. "Explanation"

Answers

Answer:

640 bagels

Rate: 40bagels/hour

Step-by-step explanation:

If the baker's at a bakery can make 160 bagels in 4 hours, then;

160 bagels = 4 hours

To calculate the amount the baker can bake in 16hours, we can write;

x bagels = 16hours

Divide both expressions

160/x = 4/16

160/x = 1/4

Cross multiply

x* 1= 160 * 4

x = 640

Hence the baker can bake 640 bagels in 16hours

To know the rate per hour, we can write;

x bagel = 1hr

Recall that; 160bagels = 4 hours

Cross multiply

x * 4 = 1 * 160

4x = 160

x = 160/4

x = 40

Hence the rate per hour is 40bagels/hour

Movies charges a $12
membership and $2 per
movie. How many movies
must be rented before the
price is the same at both
stores? What is the cost?

Answers

Answer:

4 movies, $20

Step-by-step explanation:

Given data

Family Video

charges $10 for a monthly membership and

$2.50 per movie

let the number of movies be x

and the charge for x movies be y

y= 10+2.5x----------1

Babe's  Movies

charges a $12

membership and $2 per

movie.

let the number of movies be x

and the charge for x movies be y

y= 12+2x----------2

equate 1 and 2

10+2.5x= 12+2x

collect like terms

12-10= 2.5x-2x

2= 0.5x

x= 2/0.5

x= 4 movies

put x= 4 in equation 1 or 2

y= 12+2x----------2

y= 12+2*4

y= 12+8

y= $20
