Answer: -0.5
Step-by-step explanation:
-3b = 4-2.5
-3b = 1.5
(-3b)/-3 = 1.5/-3
b = -0.5
Answer:
should be - 0.5
Step-by-step explanation:
- 3b + 2.5 = 4
1.Turn the equation around
1. -3b = -2.5 + 4.
1. The reason why you turn the 2.5 into a negative is because you basically doing the oppisite if that makes sence.
2. Add -2.5 + 4
2. -2.5 + 4 = 1.5
2. I just added.
3. Plug 1.5 into the equation. Like so
3. -3b = 1.5
3. I just replaced -2.4 + 4 with the answer
4. Divied -3b = 1.5
4. -3b/-3b = 1.5/-3b = -0.5
4. What you do to one side you have to do to the other so -3b/-3b is 0 or it just is not there anymore next you take -3b and divide it by 1.5 and get - 0.5 BAM.
5. Plug -0.5 in for b.
5. -3(-0.5) + 2.5 = 4

Find the indicated term of each sequence by repeatedly multiplying the first term by the common ratio.
Enter your answer to 5 decimal places if necessary. Use a calculator.
-40, 20,-10, ...; 5th term
The 5th term of the sequence is
Answers
Answer: -2 1/2
Step-by-step explanation:
First term = a = -40
Common ratio = 2nd term / First term = 20 / -40 = -1/2
5th term = ar⁴
5th term = -40 × (-1/2)⁴
5th term = -40 × 1/16
5th term = -2 1/2
F(x)=3x+2, if you are asked to find f(4), what does this mean?

Kim spent $44 on eating utensils. Spoons cost $4 and forks cost $6. If she bought a total of 9 utensils then how many of each kind did she buy?
Answers
Answer:
3 spoons and 6 forks
Step-by-step explanation:
9 = x + y; x= 9-y
44 = 4x + 6y
44 = 4(9-y) + 6y
44 = 36 - 4y +6y
44 = 36 +2y
2y = 44-36 = 12
y = 12/2 =6
x= 9-y = 9-6 =3
Explanation: 4 x 4= 16 + 6 x 4 = 24 + 4 = $44 or 4 x 5 = 20

N a certain year, the amount A of garbage in pounds produced after t days by an average household is given by Aequals 7.5t.
Answers
Answer:
The answer is below
Step-by-step explanation:
In a certain year, the amount A of garbage in pounds produced after t days by an average household is given by A = 7.5t.
Plot a graph for t > 0
how many days it will take to get 200 pounds of garbage.
Solution:
a) Let the time in days (t) be on the x axis and the amount of garbage (A) in pounds be on the y axis. Therefore:
At t = 0; A = 7.5(0) = 0
At t = 10; A = 7.5(10) = 75
The graph was plotted using the geogebra online graphing tool.
b) number of days require to get 200 pounds of garbage can be gotten by finding the value t for which A = 200. Therefore:
A = 7.5t
t = A / 7.5 = 200 / 7.5
t = 26.67 days
