How do I expand this? 3(2y-5)

Answers

Answer:

Given the expression $3 (2y-5)$ ......[1]

Distributive property of multiplication states that when a number is multiplied by the sum of two numbers, then the first number can be distributed to both of those numbers and multiplied by each of them separately. i.e,

$a \cdot (b+c) =a\cdot b +a \cdot c$

then, by using distributive property in equation [1]

$3(2y-5) = 3 \cdot 2y - 3\cdot 5$

= $6y-15$

Therefore, the expanded form of 3(2y-5) is; 6y-15

$3\cdot(2y-5)=3\cdot2y-3\cdot5=6y-15$

What is 7 7/8- 31/4 simplified

Answers

$7(7)/(8)-(31)/(4)=7(7)/(8)-(28+3)/(4)=7(7)/(8)-7(3)/(4)=7(7)/(8)-7(3\cdot2)/(4\cdot2)=7(7)/(8)-7(6)/(8)=\boxed{(1)/(8)}$

7 7/8 = 63/ 8 ;
31/ 4 = 62/ 8 ;
63 / 8 - 62 / 8 = 1 / 8 .

Is 63% a real number?

One month Tammy rented 3
movies and
2
video games for a total of
$20
. The next month she rented
8
movies and
4
video games for a total of
$45
. Find the rental cost for each movie and each video game.

Answers

$3x + 2y = 20$
$8x + 4y = 45$
$where x = # of movies$ and $y = # of video games$

In order to solve this systems of equations problem, you need to use the elimination method.

You can multiply the top equation, $3x + 2y = 20$ , by -2 in order to eliminate the $y$ values.

$(3x + 2y = 20) *-2$ will turn into $-6x - 4y = -40$

From there, we can eliminate.

$-6x - 4y = -40$
$8x + 4y = 45$

Since $4y$ and $-4y$ are opposites in sign and equal in coefficients, we can remove them from our equations and add the rest of the terms together.

$-6x - 4y = -40$
$8x + 4y = 45$
will turn into -->
$2x = 5$

So, x = $(5)/(2)$ , which means 1 movie costs $2.50. Then, we can solve for the video game price, $y$ , by substituting our x back into one of the equations.

$3x + 2y = 20$
$3*<span>(5)/(2) </span>+ 2y = 20$
$y = (25)/(4)$

Each movie costs $2.50 and each video game costs $6.25.

A local bowling alley charges $3 per game, plus $5 to rent a pair of shoes. Write an algebraic expression that models the cost of renting one pair shoes and bowling g games.

Answers

Answer:

5+3g

Step-by-step explanation:

This is because you pay $5 for shoes and $3 per game. Since the amount of games is unknown you put g.
