+
b
i
.
In this example,
a
=
0

Answer:
4 in. wide
Step-by-step explanation:
20/5=4
4x=16
4x/4=16/4
x=4
The answer is 29 flies.
x is the number of weeks. We have 2 weeks, so x = 3
1. Calculate the population of flies after 3 weeks: p(3) = ?
2. Calculate how much flies are eaten by the spider after 3 weeks: s(3) = ?
3. Subtract the number of flies after 3 weeks and eaten flies after three weeks: p(3) - s(3) = ?
1. p(x) = 5 · 2ˣ
p(3) = 5 · 2³ = 5 · 8 = 40
2. s(x) = 3x + 2
s(3) = 3 · 3 + 2 = 9 + 2 = 11
3. p(3) - s(3) = 40 - 11 = 29
Answer:
Use the Triangle Sum Theorem (all three angles inside a triangle add up to 180 degrees)
A is 27, C is 90 degrees (right angle) , B is unknown.
Now add. 117+B=180
B is 63 degrees.
D is 31 degrees, E is 90 degrees. F is unknown.
Add.
31+90+F=180
121+F=180
F is 59.
Step-by-step explanation:
To get a common denominator, I turned 7/8 into 35/40 and 3/10 into 12/40. I then divided 35 by 12 to get 2 11/40 servings
