Answer:
y = -18
Step-by-step explanation:
Given that,
y+29 =11
We need to find the value of y.
Subtract 29 to both sides of the above equation.
y+29-29 =11-29
y = -18
So, the value of y is equal to -18.
Simply just divide 5 and 3/5:
5/(3/5)=25/3
Therefore, 5 cups of birdseeds will last 25/3 days.
Answer:
$10
Step-by-step explanation:
Let x be the amount the youngest sister gets
x + (x+5) + (x+10) + (x+15) + (x+20) = 100
5x + 50 = 100
5x = 50
x = 10
Answer: 29.7 pounds
Step-by-step explanation:
The expression in question is w/6.
If the weight of an object on earth is w, the weight of the object on the moon is w/2.
The weight of the space suit is therefore:
= 178.2/6
= 29.7 pounds
Answer:
x = -2/15.
Step-by-step explanation:
Finding the second derivative:
f'(x) = 15x^2 +4x - 3
f"(x) = 30x + 4
30x + 4 = 0 for a point of inflection
x = -4/30 = -2/15
So 30x + 4 is negative up to x = -2/15 and positive thereafter.
So the curve passes from concave downward to concave upward at x = -2/15.
