Julie borrowed $12,000 from her aunt and $9000 from her uncle

Note the formula for simple interest = principal x time x interest rate

This question would be solved using simultaneous equation.

Two equations can be derived from the question

a - b = 3000 equation 1

(0.022 x 3 x a) + (0.045 x 3 x b) = 2007

0.066a + 0.135b = 2007 equation 2

where

a = amount borrowed from aunt

b = amount borrowed from uncle

Multiply equation 1 by 0.066

0.066a - 0.066b = 198 equation 3

subtract equation 3 from 2

0.201b = 1809

divide both sides of the equation by 0.201

b = 9000

Substitute for b in equation 1

a - 9000 = 3000

a = 9000 + 3000

a = 12,000

Answer:

$

725.40

Step-by-step explanation:

Since, every day she works from 6:15am to 4:15pm

this will put her working to 10 hrs a day and subtracting 1 hr break, the total working period would be 9 hrs a day.

And, total working hours per week would be (9*5) hrs = 45 hrs

thus, her total salary per week would be $(45*16.12) = $725.40

Answer:

[tex]\frac{43}{100}[/tex]

Step-by-step explanation:

We just convert 0.43 to [tex]\frac{43}{100}[/tex] since it's 0.43 and not any other decimal (e.g. 1.43 would be [tex]\frac{143}{100}[/tex] if you get what I mean).

Answer:

Answer: y = (2k -pw)/p

Step-by-step explanation:

[tex]k = \frac{p}{2} (y + w)[/tex]

multiply 2 on both sides:

[tex]k \times 2 = 2 \times \frac{p}{2} (y + w) \\ \\ 2k = p(y + w)[/tex]

open the bracket:

[tex]2k = py + pw[/tex]

subtract pw from both sides:

[tex]2k - pw = (py + pw) - pw \\ 2k - pw = py[/tex]

divide p on both sides:

[tex] \frac{2k - pw}{p} = \frac{py}{p} \\ \\ y = \frac{2k - pw}{p} [/tex]

Answer:

[tex]\pi {y}^{ \alpha \: so \: y = k} [/tex]

Answer: 430-8d

Step-by-step explanation:

you start with 430 dollars and you spend 8 a day. you multiply 8 by the number of days and subtract that from 430.

The algebraic expression that describes the situation is 430 - 8d.

Given,

You have $430 but you are spending $8 each day.

We need to find the algebraic expression that describes this situation where d represents the number of days.

An algebraic expression is an expression which is made up of variables and constants.

Find the algebraic expression.

Total amount = $430

Amount spend each day = $8

Let the number of days be denoted by: d

If $8 is spent daily then 8d represents the amount spent for d days.

Now,

$430 is the amount from which the money has to be spent so,

430 - 8d is the required algebraic expression.

Thus the algebraic expression that describes the situation is 430 - 8d.

Answer:

f(-10) = 6

Step-by-step explanation:

f(x) is simply just the name of the function. x will be your dependent variable that you'll use to plug into the equation.

Since they want you to find f(-10), you'll then plug -10 in where x was and solve.

f(-10) = -2((-10)+7)

f(-10) = -2(-3)

f(-10) = 6

Answer:

[tex]→f(x) = - 2(x + 7) \\ f( - 10) = - 2( - 10 + 7) \\ f( - 10) =( - 2) \times ( - 3) \\ \boxed{f( - 10) = 6}✓[/tex]
