Answer:

x=5

Step-by-step explanation:

10/(10+14)=x/(x+2x-3)

10/24=x/(3x-3)

10(3x-3)=24(x)

30x-30=24x

6x-30=0

6x=30

x=5

Answer:

<h2>h = 18 cm</h2>

Step-by-step explanation:

A=\dfrac{bh}{2}\\\\A=117\ cm^2\\b=13\ cm

Substitute:

117=\dfrac{13h}{2}               <em>multiply both sides by 2</em>

234=13h            <em>divide both sides by 13</em>

18=h\to h=18\ cm

A cash register contains only five dollar and ten dollar bills. It contains three times as many five dollar bills as ten dollar
Finger [1]

Answer:

38

Step-by-step explanation:

Let x be the number of ten dollar

Number of five dollar=3x

Total amount of money in the cash register=$950

We have to find the number of ten dollar bill in the cash register.

According to question

5\times (3x)+10x=950

15x+10x=950

25x=950

x=\frac{950}{25}

x=38

Hence, number of  ten dollar bills  in the cash register=38
