Answer:

<h2>x > 1.8</h2>

Step-by-step explanation:

\dfrac{2}{3}x-\dfrac{1}{5}>1\qquad\text{multiply both sides by 15}\\\\15\!\!\!\!\!\diagup^5\cdot\dfrac{2}{3\!\!\!\!\diagup_1}x-15\!\!\!\!\!\diagup^3\cdot\dfrac{1}{5\!\!\!\!\diagup_1}>15\cdot1\\\\(5)(2x)-3>15\qquad\text{add 3 to both sides}\\\\10x>18\qquad\text{divide both sides by 10}\\\\\boxed{x>1.8}

1. Jane saved up 20 coins, all nickels and
kompoz [17]

Answer:

10 nickels and 10 quarters

Step-by-step explanation:

Given

Number of coins: 20

Vaiue of coins = $3.00

Required

Number of Nickels and Quarters;

<em>Let N =Nickels and Q =Quarters</em>

The total coins is represented as:

N + Q = 20

1 nickel is equivalent to $0.05 and 1 quarter is equivalent to $0.25; So

0.05N + 0.25Q = 3

Make N the subject of formula in the first equation

N = 20 - Q

Substitute this in the second equation

0.05(20 - Q) + 0.25Q = 3

1 - 0.05Q + 0.25Q = 3

Collect like terms

-0.05Q + 0.25Q = 3 - 1

0.2Q = 2

Multiply both sides by 5

5 * 0.2Q = 2 * 5

Q = 10

Recall that N = 20 - Q

N = 20 - 10

N = 10

15/40 in lowest term I need it so bad now
Vesnalui [34]

In order to reduce ANY fraction to lowest terms, find any common factors
of the numerator and denominator, and divide them both by it.  If they still
have a common factor, then divide them by it again.  Eventually, they won't
have any common factor except ' 1 ', and then you'll know that the fraction is
in lowest terms.

Do  15  and  40  have any common factors ?
Let's see . . .

The factors of  15  are  1,  3,  <em>5</em>, and  15 .
The factors of  40  are  1,  2,  4,<em>  5</em>,  8,  10,  20, and  40 .

Ah hah !  Do you see that ' <em>5</em> ' on both lists ?  That's a common factor.

So  15/40  is NOT in lowest terms.

Divide the numerator and denominator both by  5 :

       15 / 40  =<em>  3 / 8</em>

3  and  8  don't have any common factor except ' 1 '. 
So  3/8  is the same number as  15/40, but in lowest terms.
