Answer: For you : 100+5x=200

For Josh : 50+10x=200

Step-by-step explanation:

Given : Cost of video game.= $200

Money you have = $100

Money you add each week = $5

Let x be the number of week, the money( in $) you have after x weeks = 100+5x

Josh has $50 in save $10 each week , then money( in $) Josh has after x weeks = 50+10x

Required equations :

For you : 100+5x=200

For Josh : 50+10x=200

Which of the following equations is equivalent to x - y = 5?
Masja [62]

Answer:

6x-6y=30

Step-by-step explanation:

<u><em>The complete options are</em></u>

a) x - 2y = 30

b) 4x - 3y = 30

c) 3x - 4y = 30

d) 6x - 6y = 30

The given equation is

x-y=5

<u>Verify option d</u>

we have

6x-6y=30

Divide by 6 both sides

(6x-6y)/6=30/6

\frac{6x}{6}-\frac{6y}{6}=\frac{30}{6}

x-y=5

therefore

x-y=5  and 6x-6y=30 are equivalent

Use a system of linear equations with two variables and two equations to solve. A number is 9 more than another number. Twice
Troyanec [42]

9514 1404 393

Answer:

  (x, y) = (3, 12)

Step-by-step explanation:

Using the given variable definitions, we can write the equations ...

  y = x + 9

  2(x +y) = 30

__

Solving the second equation for y, we have ...

  y = 15 -x

Substituting this into the first equation gives ...

  15 -x = x +9

  6 = 2x . . . . . . . . . add x-9

  3 = x . . . . . . . . . . divide by 2

  y = 3+9 = 12 . . . . substitute into the first equation

The numbers are (x, y) = (3, 12).

A is 60% of B , B is 30% of C, what percentage of C is A
zaharov [31]
A is 30% more than B. So, A = B + 30% of B = B + 30/100 *B = B + 3/10 *B = 13/10 *B. B is 60% less than C. So, B = C - 60% of C = C - 60/100 *C = C - 3/5 *C = 2/5 *C.
