Set up a linear system and solve.

Karo-lina-s [1.5K]

Answer: The smaller integer is 12, while larger integer is 23

Step-by-step explanation:

The sum of two positive integer;

a + b = 35, when smaller integer is subtracted from twice the larger integer we have, 2a - b = 34 assuming b as the smaller integer, so your equation goes this way.

a + b = 35........(1)

2a - b = 34.......(2). To solve by elimination method add both equation. We have;

3a + 0 = 69

3a = 69, divide both sides by 3.

3a/3 = 69/3 so we have;

a = 23

To know the value of b, substitute 23 for the value of a in any of the equations, let's go with (1). From one we have;

a + b = 35 if a = 23 we have;

23 + b = 35

b = 35 - 23

b = 12.

Check: a + b = 35

23 + 12 = 35

35 = 35

The answer is correct.

Sam has a jar contain 80 coins, all of which are either quarters or nickels. The total value of the coins is $14.60. How many of

DENIUS [597]

Answer:

She have 53 type of quarters and 27 type of nickels.

Step-by-step explanation:

Given:

Sam has a jar contain 80 coins, all of which are either quarters or nickels.

The total value of quarters and nickels is $14.60.

Now, to get each type of coin she have.

Let the number of quarters be $x.$

And let the number of nickels be $y.$

So, total number of coins:

$x+y=80$

$y=80-x\ \ \ ....(1)$

Now, the total value of coins:

$0.25(x)+0.05(y)=14.60$

Substituting the value of $y$ from equation (1):

$0.25(x)+0.05(80-x)=14.60$

$0.25x+4-0.05x=14.60$

$0.20x+4=14.60$

Subtracting both sides by 4 we get:

$0.20x=10.60$

Dividing both sides by 0.20 we get:

$x=53.$

The number of quarters = 53.

Now, to get the number of nickels by substituting the value of $x$ in equation (1):

$y=80-x\\\\y=80-53\\\\y=27.$

The number of nickels = 27.

Therefore, she have 53 type of quarters and 27 type of nickels.
