Answer:

{2}

Step-by-step explanation:

Testing out all values:

$3(2)+5=11\\\\6+5=11\\\\\boxed{11=11}$

The value of 2 works for the equation given.

All other values do not work, as we will result in a contradiction.

$3(3)+5=11\\\\9+5=11\\\\14\neq 11\\\\\\3(6)+5=11\\\\18+5=11\\\\23\neq 11\\\\\\3(7)+5=11\\\\21+5=11\\\\26\neq 11$

Hope this helps you.

GalinKa [24]

Answer:

1/2

Step-by-step explanation:

Both fractions can be expressed using a denominator of 10. The sum can be reduced by removing a common factor of 5 from numerator and denominator.

$\dfrac{3}{10}+\dfrac{1}{5}=\dfrac{3}{10}+\dfrac{2}{10}\\\\=\dfrac{3+2}{10}=\dfrac{5\cdot 1}{5\cdot 2}=\dfrac{1}{2}$

Step-by-step explanation:

<u>Linear Modeling</u>

It consist is setting up a linear relationship between two variables, given some experimental data. Only 2 points are needed to set up the equation of a line, but if more than 2 points are used, then the result should use statistical approaches like linear regression to find the best-fit line.

For the question at hand, Marty practices his piano lessons 11 minutes the week #1. It provides the first point (1,11). He practices 25 minutes per day on the third week. It gives us another point (3,25). This is enough to find the equation of a line. The general formula for a line, having two points (m1,w1) (m2,w2) is

$\displaystyle m-m_1=\frac{m_2-m_1}{w_2-w_1}(w-w_1)$
