Total number of slices = 12
No. of slices eaten by Kesh = 2
No. of slices eaten by Jorge = 3
No. of slices left
= Total number of slices - (No. of slices eaten by Kesh + No. of slices eaten by Jorge)
= 12 - (2 + 3)
= 12 - 5
= 7
Fraction of the pizza left
= No. of slices left/Total number of slices
= 7/12
Four point one
Or
Four and one tenths
Y=3x-1
y=3(-1) - 1
y= -3-1
y=-4
the answer is B.-4
So, you have to have your equation in terms of dimes. What you said about what he has: four more nickels than dimes in his pocket. Will help with our equation.
We know what a nickel and dime is worth. A nickel is .05 and a dime is .1
We don't know how many dimes are in his pocket, since we're trying to solve it.
.1x+(4+x).05=1.25;
In the parenthesis, it shows how there are four more nickels. Let's solve it now.
.1x + (4+x).05=1.25
.1x + .2+ .05x = 1.25; Let's add like terms.
.15x + .2 = 1.25; Subtract .2 from both sides.
.15x= 1.05
1.05÷.15= 7 =x
There are 7 dimes in his pocket, let's check our answer.
We now know there are 11 nickels, since there are four more nickels than dimes.
11(.05) +.1(7) = 1.25
.55+ .7 = 1.25
Now that we've tried it, we know there are 7 dimes in his pocket.

It is given in the question that
Ben has a collection of 812 stamps. He gives his brother 345 stamps.
And we have to find how many stamps does Ben have left .
Let x stamps are left.
So we have
Subtracting 345 from both sides
Therefore after giving 345 stamps to his brother, 467 stamps are left .
