Answer:
8 photos is the max number; correct answer is "8 or fewer photos."
Step-by-step explanation:
Write a formula for the photographer's total charges and use the operator "≤" to link this formula to $50:
$15 + ($4/photo)x ≤ $50.
Solve this for x, the number of photographs that can be purchased:
Subtracting $15 from both sides yields:
$15 + ($4/photo)x ≤ $50 => ($4/photo)x ≤ $35, or
x ≤ $35/($4/photo) = 8.75
Since we're interested onlyl in whole photos, we round this result down to 8. That's the number of photos that can be purchased for $50 or less.
we know,
where,
- a = 2 cm
- b = 5 cm
- area = 28 cm²
So,
so, missing lenght = 8 cm

Answer:
The son is 4years old
Step-by-step explanation:
Let the son's age=x
the father's age=8x
IN 10YEARS,
Son's age=x+10
father's age=8x+10
Equate them
8x+10=3(x+10)
8x+10=3x+30
5x=20
x=4
