Answer:

She have 40 coins in her purse

Step-by-step explanation:

1 dollar = 100 cents

14 dollar = 1400 cents

We are given that she has an equal number of each coin type

Let x be the no. of coins

Value of x coins of 5 cents = 5x

Value of x coins of 10 cents = 10x

Value of x coins of 20 cents = 20x

So, 5x+10x+20x=1400

35x=1400

x=\frac{1400}{35}

x=40

Hence  she have 40 coins in her purse

Find the equation of a line that is parallel to line g that contains (P, Q).
Fofino [41]

Correct option:

\boxed{x-y=P-Q}

<h2>Explanation:</h2>

Given that the line we are looking for is parallel to g, then the slope of that line and g is the same, therefore:

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\ \\ (x_{1},y_{1})=(-3,2) \\ \\ (x_{2},y_{2})=(0,5) \\ \\ \\ m=\frac{5-2}{0-(-3)}=1

So we can write the point-slope form of the equation of the line as follows:

y-y_{0}=m(x-x_{0}) \\ \\ (x_{0},y_{0})=(P,Q) \\ \\ \\ y-Q=1(x-P) \\ \\ y-Q=x-P \\ \\ \\ Arranging: \\ \\ P-Q=x-y \\ \\ \boxed{x-y=P-Q}

What is the value of the expression <br> 3<br> 6 - (- 11.5)?<br> 4
Digiron [165]

Answer: 31 hope this helped

Step-by-step explanation: I'm assuming your problem looks like this: 4+5*6-3 =? To solve this problem you need to use the order of operations. PEMDAS which stands for Parentheses, exponents, multiply and divide, and lastly add and subtract. You must multiply and divide before you add and subtract so you must do 5*6 first. You now get 4+30-3. Now all you have left is addition and subtraction so you now just go from right to left and do one at a time. So 4+30 = 34 , 34-3=31. Therefore your answer should be 31. Hope that helped!
