V = 19

First step : -76 + 4v = 4 × ( v - 19)

Second step: solve: 4 = 0

Second part 2: v - 19 = 0

Add 19 from both sides of the equation:

So, that's how I came up with "v" equaling to '19"

Find the slope of the line with equation 4x-5=20.(hint: Finding some points on the line first -perhaps the x-and y-intercepts-ma

Hunter-Best [27]

That's not the equation of a line. It just says that x=6.25 .

Since there's no line here, there's no slop or intercept involved.

John has four more quarters than dimes. If he has $5.20 in quarters and dimes, how many of each type coin does he have?

Airida [17]

Answer:

John has 16 quarters and 12 dimes

Step-by-step explanation:

Quarters are worth $0.25 each and Dimes are worth $0.10 each.

Let number of dimes John has be $d$ and number of quarters he has be $q$

Given in the problem, "John has four more quarters than dimes". This means:

$q-4=d$

This is Equation 1.

Given in the problem, "If he has $5.20 in quarters and dimes". This means:

$0.25q+0.1d=5.20$

This is Equation 2.

Now, substituting Equation 1 into Equation 2 and solving for q gives us:

$0.25q+0.1(q-4)=5.20\\0.25q+0.1q-0.4=5.20\\0.35q=5.20+0.4\\0.35q=5.60\\q=16$

There are 16 quarters.

Now using this fact, we use this value in Equation 1 to get the number of dimes.

$q-4=d\\16-4=d\\12=d$

There are 12 dimes.

Hence, John has 16 quarters and 12 dimes.
