Suppose you have a pocketful of change. You have some pennies (p) and some quarters (q). One expression could be used to describ

faltersainse [42]

Answer:

1.57

Step-by-step explanation:

So we have two equations regarding the number of quarters q and the number of pennies p:

$p+q$

Which represents the total amount of coins and

$0.01p+0.25q$

Which represents the total amount of money in dollars.

So we are asked to evaluation each expression for the situation in which we have 6 quarters and 7 pennies. Thus, plug 6 in for q and 7 in for p:

$p+q\\(7)+(6)=13$

This tells us that we have 16 coins in total.

$0.01(7)+0.25(6)\\=0.07+1.50\\=1.57$

This tells us that we have a total amount of $1.57.

Can someone help plz

olchik [2.2K]

Answer:

A.) 2x - 9x - 30 = -6

Step-by-step explanation:

hello !

to solve this system of equations, first, we substitute the equation $y = 3x + 10$ to the y variable in the equation $2x-3y = -6$ . Therefore, we get:

$2x - 3(3x+10)=-6$

now, we simplify by multiplying -3 to the variables inside the parenthesis, which, in short, is also called the distributive property. thus, we get:

$2x - 9x - 30 = -6$

Nick's Printing Press promptly sold 5-cent pencils and 10-cent pens to the public. It sold 1000 writing utensils and took $74.50

galben [10]

Answer:

490 pens
510 pencils

Step-by-step explanation:

Let p represent the number of pens Nick sold. Then the revenue is ...

0.10p +0.05(1000 -p) = 74.50

0.05p = 24.50 . . . . . . eliminate parentheses, subtract 50

p = 490 . . . . . . . . . . . . multiply by 20

The number of pencils sold is then ...

pencils = 1000 -490 = 510

Nick's Printing Press sold 490 pens and 510 pencils.
