Quarters (Q): $0.25

Nickels (N): $0.05

Quantity:  Q   +    N   = 27          →   -.05(Q + N = 27)        →   -.05Q  - .05N  = -1.35

Worth:   .25Q + .05N = 2.75      → 1(.25Q + .05N = 2.75)   →   <u>.25Q  + .05N = 2.75</u>

                                                                                                  .20Q              = 1.40

                                                                                                        Q             = 7  

Answer: 7 quarters

What value of x makes the equation true?<br><br> 16 + (18 + 10) = (x + 18) + 10<br><br> x = ?
choli [55]

Answer:

  See below

Step-by-step explanation:

16 + (18 + 10) = (x + 18) + 10x

16 + 28 = (x + 18) + 10x        Add like terms in the parentheses

44 = (x + 10x) + 18               Use the community property to regroup like

                                            terms

44 = 11x + 18                         Simply

<u>-18 =        -18</u>                         Substract 18 from both side

26  = 11x                               Simply

<u>26</u>  =  <u>11x</u>                              Divide by 11

11        11

2\frac{4}{11} = x                               Reduce

If f(x)=x²-6 x+2 and g(x)=-2x, find the following composition. (g ° f)(5)<br> (g ° f)(5)=
Elan Coil [88]

What the composite function in the question is actually trying to explain is;

  • (gof)(x)=g(f(5))

First of all, in the function F(x), we will find a result by writing 5 where we see the letter x.

  • F(5)=5^2-6(5)+2=-3

We will write this result in the G(x) function where we see the letter x and we will get the result.

  • G(-3)=-2(-3)=6
