How do you solve 2/7k - 3/8 = -19/8

1 answer:

8 0

Alright, start with simplifying both sides
$\frac{2}{7} k+ \frac{-3}{8} = \frac{-19}{8}$
Than add $\frac{3}{8}$ to both sides.
$\frac{2}{7}k + \frac{-3}{8} + \frac{3}{8} =\frac{-19}{8} + \frac{3}{8}$
which is $\frac{2}{7} k=-2$

After this, multiply each side by $\frac{7}{2}$
$( \frac{7}{2})* \frac{2}{7} k= ( \frac{7}{2})*(-2)$
So, your final answer is K=-7

Answer:

Option d. PQ = YZ

Step-by-step explanation:

The question in English is

Choose the most appropriate answer. The PQR triangle and the XYZ triangle are two congruent triangles. The angle P = the angle Y and PR = YX. Side pairs of the same length are ... a. PQ = XZ b. QR = YZ c. QR = XY d. PQ = YZ

we know that

If two triangles are congruent, then its corresponding sides and its corresponding angles are congruent

Corresponding sides are named using pairs of letters in the same position on either side of the congruence statement

we have that

$m\angle P=m\angle Y$
