So,
Let Mercado's age be m and his daughter's age be d.
Our first equation: m = 37
Our second equation: m = 5 + 4d
Substitute 37 for m
37 = 5 + 4d
Subtract 5 from both sides
32 = 4d
Divide both sides by 4
8 = d
His daughter is 8 years old.
Answer:
x = 8
Step-by-step explanation:
log(5x-4)-log(x+1)=log 4
log [ (5x - 4) / (x+ 1) ] = log 4
[ log (a/b) = loga - logb]
(5x - 4 ) / ( x + 1) = 4
(5x - 4) = 4x + 4
5x - 4x = 4 + 4
x = 8
Hope it will help :)❤
Circle equation
(x-h)^2 + (y-k)^2 = r^2
where (h.k) is the center and r is the radius
(x -7)^2 + (y+10)^2 = 4
Answer:
C
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
A hexagon has 6 sides, so n = 6
sum = 180° × (6 - 2) = 180° × 4 = 720° → C
