He can make 25 scarves from 15 balls of yarn.

Step-by-step explanation:

Given,

Yarn used for one scarf = \frac{3}{5} of a ball

Yarn purchased = 15 balls

Let,

x be the number of scarves.

Yarn used for one scarf*number of scarves = Yarn purchased

\frac{3}{5}x=15

Multiplying both sides by \frac{5}{3}

\frac{5}{3}*\frac{3}{5}x=15*\frac{5}{3}\\x=\frac{75}{3}\\x=25

He can make 25 scarves from 15 balls of yarn.

4/10x - 2x + 8/5 = 4/5
mamaluj [8]

\large\displaystyle\text{$\begin{gathered}\sf \left(\frac{4}{10}\times x\right)-(2 \times x)+\frac{8}{5}=\frac{4}{5}    \end{gathered}$}

Reduce the fraction 4/10, to its minimum expression, extracting and canceling 2.

  • \large\displaystyle\text{$\begin{gathered}\sf \frac{2}{5}x-2x+\frac{8}{5}=\frac{4}{5}    \end{gathered}$}

Combine \bf{\frac{2}{5}x } and -2x to get \bf{-\frac{8}{5}x}.

  • \large\displaystyle\text{$\begin{gathered}\sf -\frac{8}{5}x+\frac{8}{5}=\frac{4}{5} \     \end{gathered}$}

Subtract 8/5 from both sides.

  • \large\displaystyle\text{$\begin{gathered}\sf -\frac{8}{5}x=\frac{4}{5}-\frac{8}{5} \ \    \end{gathered}$}

Since 4/5 and 5/8 have the same denominator, join their numerators to subtract them.

  • \large\displaystyle\text{$\begin{gathered}\sf -\frac{8}{5}x=\frac{4-8}{5}   \end{gathered}$}

Subtract 8 from 4 to get -4.

  • \large\displaystyle\text{$\begin{gathered}\sf -\frac{8}{5}x=-\frac{4}{5}   \end{gathered}$}

Multiply both sides by \bf{-\frac{5}{8}}, the reciprocal of \bf{-\frac{5}{8}}.

  • \large\displaystyle\text{$\begin{gathered}\sf x=-\frac{4}{5}\left(-\frac{5}{8}\right)   \end{gathered}$}

Multiply -4/5 by -5/8 (to do this, multiply the numerator by the numerator and the denominator by the denominator).

  • \large\displaystyle\text{$\begin{gathered}\sf x=\frac{-4(-5)}{5\times8} \ \to \ \ Multiply  \end{gathered}$}
  • \large\displaystyle\text{$\begin{gathered}\sf x=\frac{20}{40}  \end{gathered}$}

Reduce the fraction 20/40 to its lowest expression by extracting and canceling 20.

  • \boxed{\large\displaystyle\text{$\begin{gathered}\sf x=\frac{1}{2}  \end{gathered}$}}

Please help me solve this #algebra #algebra1
Vesna [10]

Answer:

h = 430

Step-by-step explanation:

1290 = h/10 + h/5             Make h/5 into something that is something / 10

1290 = h/10 + 2h/(5*2)     Clean up the brackets.

1290 = h/10 + 2h/10         Add the right.

1290 = 3h/10                    Multiply both sides by 10

1290*10 = 10(3h/10)          

12900 = 3h                       Divide both sides by 3

h = 430
