Answer:
Q.1. x=8-5

Q.2. -3x=16-7
-3x=9
x=-9/3
x=-6
Q.3. 3p=6*7
3p=42
p=42/3
p=16
Q.4. 2(x+5)=24
2x+10=24
2x=24-10
2x=14
x=14/2
x=7
Step-by-step explanation:
For Q1.
1. x + 5 = 8
x = 8 - 5
x = 3
2. -3x + 7 = 16
-3x = 16 - 7
-3x = 9
x = 9/-3
x = -3
3. 3P/7 = 6
3P = 6*7
3P = 42
P = 42/3
P = 14
4. 2(x + 5) = 24
2x + 10 = 24
2x = 24 - 10
x = 14/2
x = 7
5. x/5 - 8 = 9
x/5 = 9 - 8
x = 5
For Q.2:
1. 12 + 4(x + 3(x + 4)) = 108
12 + 4(x + 3x + 12) = 108
12 + 4x + 12x + 48 = 108
60 + 16x = 108
6x = 108 - 60
x = 48/6
x = 8
2. 5x + 7(4 - (x + 3)) = 31
5x + 28 - x + 3 = 31
6x + 31 = 31
6x = 0
x = 0
3. 2(3y - 2(y + 5) + 3) = -4
2(3y - 2y + 10 + 3) = -4
2(y + 13) = -4
2y + 26 = -4
2y = 30
y = 15
4. 20 - 2(2x -(2 - x) + 10) = -44
20 - 2(2x - 2 + x + 10) = -44
20 - 2(3x + 8) = -44
20 - 6x - 16 = -44
4 - 6x = -44
-6x = -44 - 4
-6x = -48
x = -48/-6
x = 8
5. 5(3x - 4(x + 2) + 5(2x + 1)) = 60
5(3x - 4x - 8 + 10x + 5) = 60
5(3x - 4x + 10x - 8 + 5) = 60
5(9x - 3) = 60
45x -15 = 60
45x = 60 + 15
x = 75/45
x = 1.67
For Q.3:
1. x/2 + x/3 = 10
(3x + 2x)/6 = 10
5x/6 = 10
5x = 60
x = 12
2. 1/3(2x/7 - 1) = 3
1/3(2x - 7/7) = 3
2x - 7/7 = 3/(1/3)
2x - 7/7 = 1
2x - 7 = 7
2x = 14
x = 7
3. (P + 2/2) + ( 2P - 6/4) = 5
(2P + 4 + 2P - 6)/4 = 5
(4P - 2)/4 = 5
4P - 2 = 20
4P = 22
P = 5.5
4. x/3 - (2x + 1)/3 - (x - 3)/5
(x - 2x + 1)/3 - (x - 3)/5
(1 - x)/3 - (x - 3)/5
(5 - 5x - 3x - 9)/15
(-8x - 4)/15
5. (y - 2)/3 + (2y + 5)/5 - (y + 7)/3
5/3 + (2y + 5)/5
(25 + 6y + 15)/15
(40 + 6y)/15

Answers
Answer:
12 gamesStep-by-step explanation:
Let the number of games is g
Total cost at Mar Vista:
3.5g + 2Total cost at Pinz:
3.25g + 5Since same amount spent in both places, we have:
3.5g + 2 = 3.25g + 53.5g - 3.25 = 5 - 20.25g = 3g = 3/0.25g = 12Answer:
12
Step-by-step explanation:
Let the game be x
3.5x + 2 = 3.25x + 5
3.5x - 3.25x = 5 - 2
0.25x = 3
x = 3/0.25
x = 300/25
x = 12

What is sum of two numbers?In mathematics, summation exists the addition of a series of any kind of numbers, named addends or summands; the result is their sum or total.
A sum exists as the result of an addition. For example, adding 1, 2, 3, and 4 provides the sum of 10, written. (1) The numbers being summed are named addends, or sometimes summands.
A summation, also named a sum, is the outcome of arithmetically adding numbers or quantities. A summation always includes a whole numeral of terms. There can be as irregular as two terms, or as many as a hundred, a thousand, or a million. Some summations include infinitely many terms.

5. Use your answers to questions 3 and 4 to write an expression for how many times greater organism B's population is than organism A's population after 8 days. Simplify your expression, then write it as a number that is not in exponential form. Show your process. Write your answer in the space below. My answer
Answers
Population growth represents the rate at which the population changes
The expression for the number of times the population of B is greater than A is: [tex]2^6[/tex]The expression that is not in exponential form is: 64Given that:
[tex]r_1 = 2[/tex] ----- i.e. when the population doubles
[tex]r_2 = \frac{1}{2}[/tex] ----- i.e. when the population cut in halves
Population growth is represented as: [tex]A_n = ar^{n}[/tex]
Organism A
For the first 5 days (when it doubles) is:
[tex]A_5 = ar_1^{5[/tex]
Substitute [tex]r_1 = 2[/tex]
[tex]A_5 = a\times 2^{5[/tex]
For the next 3 days (when it cut in halves) is:
[tex]A = A_5 \times r_2^3[/tex]
Substitute [tex]A_5 = a\times 2^{5[/tex] and [tex]r_2 = \frac{1}{2}[/tex]
[tex]A= a \times 2^5 \times (\frac{1}{2})^3[/tex]
Apply law of indices
[tex]A = a \times 2^5 \times 2^{-3[/tex]
[tex]A = a \times 2^{5-3[/tex]
[tex]A = a \times 2^{2[/tex]
So, the growth factor of organism A is:
[tex]A = a \times 2^{2[/tex]
Organism B
For the 8 days, we have:
[tex]B=ar_1^8[/tex]
[tex]B=a\times 2^8[/tex]
The expression (n) for the number of times the population of B is greater than A is:
[tex]n = \frac BA[/tex]
This gives:
[tex]n = \frac{a \times 2^8}{a \times 2^2}[/tex]
[tex]n = \frac{2^8}{2^2}[/tex]
Apply law of indices
[tex]n = 2^{8-2}[/tex]
[tex]n = 2^{6}[/tex]
The expression that is not in exponential form is:
[tex]n = 2 \times 2\times 2\times 2 \times 2\times 2[/tex]
[tex]n = 64[/tex]
Hence:
The expression for the number of times the population of B is greater than A is: [tex]2^6[/tex]The expression that is not in exponential form is: 64Read more about population growth at:
