Jamila and Akiko had the same amount of money to spend. After Jamila spent $33 and Akiko spent$42, Jamila had 4 times as much money left as Akiko. How much money did each of them have in
the beginning?

Answers

Answer: $45

Step-by-step explanation: Let the amount of money be x ,

Then , after Jamila spent $33 , the remaining money is x-33,

Also , after Akiko spent $42 , the remaining money is x- 42,

since Jamila is now having 4 times as much money left as Akiko, we have

x - 33 = 4 ( x - 42)

x - 33 = 4x - 168

-33+168 = 4x - x

135 = 3x

Therefore ,

x = 45

How to find the derivative of this?

Answers

I cant see all the question but this is how you find the derivative of your function using the product rule.

Here you use the extension of the product rule to 3 factors which we'll write as:-

f(x), g(x) and h(x):-

Derivative = f'(x) g(x) h(x) + f(x) g'(x) h(x) + f(x) g(x) h'(x)

(3x - 1)(x + 4)(2x - 1)

derivative = 3(x + 4)(2x - 1) + (3x + 1)(1)(2x - 1) + (3x - 1)(x + 4)(2)

= 3(x + 4)(2x - 1) + (3x + 1)(2x - 1) + 2(3x - 1)(x + 4)

What is the area of a parallelogram that has a base of 12 3/4 in. and a height of 2 1/2 in.?

Answers

To find the area of a parallelogram you use the formula A=bh. The base of your parallelogram is 12.75 and your height is 2.5. Just plug the numbers into the formula. A=12.75(2.5) Your final answer is: A=31.875 or 31 875/1000 in fraction form

A=LxW
12.75x2.5=31.875 squared inches
