Answer:

$t = 2.5 \\ j = 3.75$

Step-by-step explanation:

$5t + 6j = 35 \\ 3t + 2j = 15 = > 2j = 15 - 3t \\ \\ 5t + 3(15 - 3t) = 35 \\ 5t + 45 - 9t = 35 \\ - 4t + 45 = 35 \\ - 4t = - 10 \\ 4t = 10 \\ t = 2.5 \\ \\ 3(2.5) + 2j = 15 \\ 7.5 + 2j = 15 \\ 2j = 7.5 \\ j = 3.75$

Check:

$5t + 6j = 35 \\5(2.5) + 6(3.75) = 35 \\ 12.5 + 22.5 = 35 \\ 35 = 35 \\ \\ 3t + 2j = 15 \\ 3(2.5) + 2(3.75) = 15 \\ 7.5 + 7.5 = 15 \\ 15 = 15$

What is the value of y?

Amiraneli [1.4K]

Answer:

$\boxed{D. \: 40\degree}$

Step-by-step explanation:

Angle sum property of triangle states that the sum of interior angles of a triangle is 180°

So,

$= > 2y \degree + (y + 10)\degree + 50\degree = 180\degree \\ \\ = > 2y\degree + y\degree + 10\degree + 50\degree = 180\degree \\ \\ = > 3y\degree + 60\degree = 180\degree \\ \\ = > 3y\degree = 180\degree - 60\degree \\ \\ = > 3y\degree = 120\degree \\ \\ = > y = \frac{120\degree}{3\degree} \\ \\ = > y = 40\degree$
