Answer:
D
Step-by-step explanation:
There are 187 nickels and 66 dimes in the jar.
Step-by-step explanation:
Given,
Total coins = 253
Value of coins = $15.95 = 15.95*100 = 1595 cents
Value of each nickel = 5 cents
Value of each dime = 10 cents
According to given statement;
x+y=253 Eqn 1
5x+10y=1595 Eqn 2
Multiplying Eqn 1 by 5

Subtracting Eqn 3 from Eqn 2

Dividing both sides by 5

Putting y=66 in Eqn 1

There are 187 nickels and 66 dimes in the jar.

Answer:
Slope: 1/5
Step-by-step explanation:
-1,2
4,3
-1 - 2 = -1
-1 - 4 = -5
-1/-5 = 1/5
Since EF=FG, you can set 6x - 10 = to 3x + 11

Then add like terms

so,

Now you can divide by 3 to get

:)
then put it back into


so,
I believe that x=20 from the math i did hopefully its helpful.
