Three years ago , Ahmed was one third of his sister's age. In a years time ,Ahmed's age doubled will match his sisters age. How old is Ahmed now.


Help the due is tomorrow

Answers

Answer 1
let the age of ahmed three years ago be x years old. since 3 years ago ahmed as one third of his sister's age, his sister would be 3x years old 3 years ago.

in a year's time, ahmed would be x+4 years old and his sister would be 3x+4. we also know that in a year's time ahmed's age doubled will match his sister's age. hence 2(x+4)=3x+4
2x+8=3x+4
4=x
x is the age of ahmed three years ago. hence, now ahmed is 7 years old.

Sean wants to spend (example) $100 on clothing and he wants to purchase
6 additional items for his wardrobe. Each pair of pants costs $20 and each shirt costs $15.
Show the solution graphically.

Point (2, 4)

Answers

Answer:

Step-by-step explanation:

Let x be the number of pants and y be the number of shirts

x + y = 6

20x + 15y = 100

multiply the first equation by -20

-20x -20y = -120

20x + 15y = 100

subtract the equations

-5y = -20

y = 4

replace y in equation 1

x + 4 = 6

x = 2

Suppose that you need to buy some chicken for dinner tonight. You found an ad showing that a store across town has chicken on sale for $2.99 per pound. Your usual neighborhood store sells the same chicken for $3.79 per pound. You are considering whether it is worth the drive to purchase the chicken from the store across town. Information you will need:________
A. You need to purchase 3 pounds of chicken
B. Your neighborhood store is 2.1 miles away and takes about 8 minutes to get there
C. The store across town is 8.6 miles away and takes about 24 minutes to get there
D. Your car averages about 22 miles per gallon in the city Gas is $3.05 per gallon

Answers

Answer:

C). The store across town is 8.6 miles away and takes about 24 minutes to get there.

D). Your car averages about 22 miles per gallon in the city Gas is $3.05 per gallon.

Step-by-step explanation:

The information regarding the distance of the store across town from the house, the time required to reach there, the average of the car, and the cost of gas per gallon would assist in calculating if the extra drive is worth buying chicken from the city store.

Cost of chicken in the city store - $2.99 per pound

Average of the car in 1 gallon = 22miles

so, the average of the car in 1 mile = 1/22

Cost of traveling 8.6miles = 8/22 * $3.05

                                           = 24.40/22

Additional cost = $ 1.109

Total cost of buying chicken from the city store = $2.99 + $1.10

                                                                                = $4.09

Hence, it is not worth to buy the chicken from the store across the town as it is costlier in comparison to $3.79 in nearby store.

Step-by-step explanation:

Denote the smallest integer as "x"; hence the next integer will be "x + 2", and the third will be "x + 4".

Using the information, set up an equation:

x + x + 2 + x + 4 = 66

Simplify

x + x + 2 + x + 4 = 66

3x + 6 = 66

Inverse operations

3x + 6 = 66

b) [tex]4^{3x}[/tex] = [tex]2^{x+1}[/tex]

(include steps pleez)

Answers

Answer:

Question a)

[tex]9^{3x+4}=27^{4x+3}[/tex]

[tex]x=-0.166[/tex]

Question b)

[tex]4^{3x}=2^{x+1}[/tex]

[tex]x=0.2[/tex]

Step-by-step explanation:

Question a)

Given the expression

[tex]9^{3x+4}=27^{4x+3}[/tex]

Taking log on both sides

[tex]log\left(9^{3x+4}\right)=log\left(27^{4x+3}\right)[/tex]

[tex]\left(3x+4\right)\cdot \left(log\left(9\right)\right)\:=\left(4x+3\right)\cdot \left(log\left(27\right)\right)[/tex]

[tex]3x+4=\left(\frac{log\left(27\right)}{log\left(9\right)}\right)\cdot \left(4x+3\right)[/tex]

[tex]3x+4=1.5\times \left(4x+3\right)[/tex]

[tex]3x+4=6x+4.5[/tex]

[tex]3x=6x+0.5[/tex]

[tex]\frac{-3x}{-3}=\frac{0.5}{-3}[/tex]

[tex]x=-0.166[/tex]

Therefore, the value of x:

[tex]x=-0.166[/tex]

Question b)

Similarly, we can solve the 'b' expression

Given the expression

[tex]4^{3x}=2^{x+1}[/tex]

Taking log on both sides

[tex]log\left(4^{3x}\right)=log\left(2^{x+1}\right)[/tex]

[tex]3x\cdot \left(log\left(4\right)\right)=\left(x+1\right)\cdot \left(log\left(2\right)\right)[/tex]

[tex]3x=\left(\frac{log\left(2\right)}{log\left(4\right)}\right)\cdot \left(x+1\right)[/tex]

[tex]3x=0.5\times \left(x+1\right)[/tex]

[tex]3x=0.5x+0.5[/tex]

[tex]2.5x=0.5[/tex]

Divide both sides by 2.5

[tex]\frac{2.5x}{2.5}=\frac{0.5}{2.5}[/tex]

[tex]x=0.2[/tex]

Therefore, the value of x = 0.2
