Answer:
Tootsie Rolls = 13
Step-by-step explanation:
Given:
Milky Ways and Tootsie Rolls together were 15 more than the number of Reese's Cups.
There were 4 fewer Reese's Cups than Hershey Bars.
There were 12 Milky Ways and 14 Hershey Bars.
Solution
Milky Ways and Tootsie Rolls = Reese's Cups + 15
There were 4 fewer Reese's Cups than Hershey Bars.
Hershey Bars = 14
Then,
Reese's Cups = 14 - 4
= 10
Milky ways = 12
Hershey bars = 14
Reese's Cups = 10
Milky ways = 12
Milky Ways + Tootsie Rolls = Reese's Cups + 15
12 + Tootsie Rolls = 10 + 15
12 + Tootsie Rolls = 25
Subtract 12 from both sides
Tootsie Rolls = 25 - 12
= 13
Tootsie Rolls = 13
Answer:
No, he is incorrect because he forgot to multiple the negative by the x, and only multiplied 3 by x instead of -3 by x.

Answer:
= 8.9 units
Step-by-step explanation:
When a chord intersects with a tangent outside a circle then we use the relationship;
X ² = AO × BO, Where A and are the points of intersection of the chord an the circle, while O is the point of intersection between the chord and the tangent.
Therefore;
x² = 4 × 20 or 8 × 10
x² = 80
x = √80
= 8.944
≈ 8.9
