Assume Keesha has d dimes, so she has d + 10 quarters

Total money Keesha has is (d+10)*.25 + d*.1 = 11.25

or 0.35d + 2.5 = 11.25

Solving for d , d = 25

So Keesha has 25 dimes and 35 quarters, total of 60 coins

Answer:

x=1, y=-4. (1, -4).

Step-by-step explanation:

y=-7x+3

y=-x-3

Solving for Y

3x+y=2

y=2-3x

y=2-3x,x R

Solving for X

3x+y=2

3x=2-y

x= 2/3-1/3y

x=2/3-1/3y

Find the x-intercept

3x+y=2

3x+0=2

3x=2

x=2/3

Find the y-intercept

3x+y=2

3 times 0+y=2

y=2
