Write 3x+4y=12 in slope intercept form
cestrela7 [59]
Ok, let’s take it step by step.
In order to write an equation in slope intercept form, solve for y.
3x+4y=12
First, subtract 3x from both sides.
4y=-3x+12
Now, divide both sides by 4.
y=-3/4x+3.

So, 3x+4y=12 written in slope intercept form is y=-3/4x+3.

Jo jo has a total amount of $12.45 in quarters and dimes in his pocket. he has a total of 60 coins. how many quarters and dimes
baherus [9]

Given:

Total number of coins (Quarters and dimes) = 60

Total amount = $12.45

To find:

The number of quarters and dimes.

Solution:

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

We know that,

1 quarter = 0.25 dollar

1 dime = 0.10 dollar

Total coins: x+y=60               ...(i)

Total amount: 0.25x+0.10y=12.45             ...(ii)

From (i), we get

y=60-x          ...(iii)

Putting this value in (ii), we get

0.25x+0.10(60-x)=12.45

0.25x+6-0.10x=12.45

0.25x-0.10x=12.45-6

0.15x=6.45

Divide both sides by 0.15.

x=\dfrac{6.45}{0.15}

x=43

Putting x=43 in (iii), we get

y=60-43

y=17

So, the number of quarters is 43 and the number of dimes is 17.

Therefore, the correct option is b.
