Answer:
24
Step-by-step explanation:
since these are fairly small numbers it's easier to figure out. for each number just think of the 2 closest perfect square, for 10, the 2 closest perfect squares are 9 & 16, which means square root of 10 is more than 3 but less than 4,
14 also has the same perfect squares as 10, so 10&14 aren't possibilities
the closest perfect squares to 24 are 16 and 25
the square root of 16 is 4 and the square root of 25 is 5
that means root 24 is between 4 and 5
if you're confused just ask me & i'll try to explain it a different way ♡
Find attached solution.
With Rough Work by the right hand side.
Note that when you carry out the division, you then multiply out with the divisor, (y-3)
I hope this helps.

x-intercept(s): (6,0)
Answer:
Carl has 35 dimes and 90 quarters
Step-by-step explanation:
Let the number of quarters be q and the number of dimes be d
Total number of coins is 125;
Hence;
q + d = 125 •••••••••(i)
The total value of quarters present = q * 0.25 = 0.25q
The total value of dimes present = d * 0.1 = 0.1d
Adding both gives the total
0.25q + 0.1d =26 ••••••••(ii)
So we need to solve both equations simultaneously;
From i,
q = 125 - d
Substitute this into ii
0.25(125-d) + 0.1d = 26
31.25 -0.25d + 0.1d = 26
31.25 -26 = 0.25d -0.1d
5.25 = 0.15d
d = 5.25/0.15
d = 35
Recall; q = 125 - d = 125 -35 = 90
