A + b = dr, solve for a

1 answer:

6 0

Hey there!

Since we don't have values for b, d, and r, we can't get a specific number for the value of a, if that makes sense. It'll be represented by these variables.

To solve, we need to make sure the equation looks like a = ? .

Subtract b from each side of the equation.

a = dr - b

Now we have solved for a.

Hope this helps!

Rob has $1.65 in nickels and dimes. He has 25 coins in all. How many of each kind of coin are there?

valentinak56 [21]

Answer:

The number of nickels is 17 and number of dimes is 8.

Step-by-step explanation:

Let the number of nickels be x and number of dimes be y.

Total number of coins is 25.

$x+y=25$ .... (1)

$\$1=100\text{ cents}$

$1\text{ nickel}=5\text{ cents}$

$1\text{ dimes}=10\text{ cents}$

$5x+10y=1.65\times100$

$5x+10y=165$ .... (2)

On solving (1) and (2), we get

$5x+10(25-x)=165$

$-5x+250=165$

$-5x=-85$

$x=17$

Put this value in equation 1.

$17+y=25$

$y=8$

Therefore the number of nickels is 17 and number of dimes is 8.

-18+(-29)+(-10) -24+(-16)+-28+-19 -151-253-34-17 Help me with these

olasank [31]

-18 +(-29) = -47 + (-10) = -57

-24 + (-16) = -40 + (-28) = -68 +(-19) = -87

-151 - 253 = -404 - 34 = -438 - 17 = -455
