A person has a bag containing dimes and nickels. There are a total of 120 coins in the bag, and the total value of the coins is
telo118 [61]

Answer:

There are 65 dimes. There are 55 nickels.

Step-by-step explanation:

This question can be solved using a system of equations.

I am going to say that:

x is the number of dimes

y is the number of nickels.

There are a total of 120 coins in the bag

This means that x + y = 120.

The total value of the coins is $9.25.

The dime is worth $0.10 and the nickel is worth $0.05. So

0.1x + 0.05y = 9.25

System:

x + y = 120

0.1x + 0.05y = 9.25

From the first equation:

y = 120 - x

Replacing in the second:

0.1x + 0.05y = 9.25

0.1x + 0.05(120 - x) = 9.25

0.1x + 6 - 0.05x = 9.25

0.05x = 3.25

x = \frac{3.25}{0.05}

x = 65

y = 120 - x = 120 - 65 = 55

There are 65 dimes. There are 55 nickels.

Okay so you plug in 6.7 to M because that’s how far you are.
You are looking for T because it says seconds after.
So 6.7=t/4.6
then you multiply both sides by 4.6.
6.7x4.6=30.82.
So your answer is 30.82

Find the equation of the line with a slope of 12 that passes through the point (3, -1)
Anon25 [30]

Answer:

y = 12x - 37

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = 12, thus

y = 12x + c ← is the partial equation

To find c substitute (3, - 1) into the partial equation

- 1 = 36 + c ⇒ c = - 1 - 36 = - 37

y = 12x - 37 ← is the equation of the line
