Step-by-step explanation:
Anya's current age is 30 years and Cole current age is 27 years
Let x represent Anya current age and y represent Cole current age.
Anya is three years older than her brother, Cole. Hence:
x = y + 3
x - y = 3 (1)
In 11 years, the sum of their ages will be 79. Hence:
(x + 11) + (y + 11) = 79
x + y = 57 (2)
Solving equations 1 and 2 simultaneously gives:
x = 30, y = 27
Anya's current age is 30 years and Cole current age is 27 years

Answer:
<em>x = 5/3 </em>or<em> x = -3</em>
Step-by-step explanation:
3x² + 4x - 15 = 0
Factor left side.
(3x - 5)(x + 3) = 0
Set factors equal to 0.
3x - 5 = 0
3x = 5
x = 5/3
x + 3 = 0
x = -3

Answer:
7/24 Is The Answer!
Step-by-step explanation:
Division of fractions is equivalent to multiplication by the reciprocal of the second fraction:
1/4 Divided by 6/7 = 1/4 ₓ 7/6
Once rearranged, multiply all of the numerators by each other. Do the same with the denominators and form a new fraction with these values:
1/4 times 7/6 = 7/24
The result Is
1/4 divided by 6/7 = 7/24
