The line with equation ax+by=20 passes through the points(-2,10) and (1,5)<br>find a and b
Doss [256]
ax+by=20 \\ \\(-2,10) \\ \\ a*(-2)+b*10 = 20 \\ \\-2a +10b = 20 \\ \\ (1,5)\\ \\ a*1+b*5 = 20 \\ \\ a +5b = 20
 
\begin{cases} -2a+10b =20\\ a+5b =20 \ /*2\end{cases} \\ \\\begin{cases} -2a+10b =20\\ 2a+10b =40 \end{cases}\\--------\\ 20b=60 \ / :20 \\ \\b=\frac{60}{20} =3

-2a+10b=20 \\ \\-2a +10*3=20 \\ \\-2a +30=20\\ \\-2a=20-30\\ \\-2a=-10 \ /: (-2)

a=\frac{10}{2}=5\\ \\\begin{cases} a= 5 \\b=3\end{cases}

Beatrice makes a jar of dry soup mix. The ingredients are: 1 ¾ cups of uncooked rice
Lapatulllka [165]

Answer:

5 cups of soup mix

Step-by-step explanation:

3. You can make the addition easier by finding a common denominator 12.

7/4 + 1/2 + 5/3 + 1/3 + 1/4 + 1/2  --> 21/12 + 6/12 + 20/12 + 4/12 + 3/12 + 6/12

To do this you need to multiply every numerator and denominator by the same number until the denominator is equal to 12. When it is 12 you can add up all the fractions to get 5.

I hope this helps!
