How to show my daughter to do this and it needs to be changed to a mix number.

Solution 1 by separating parts

Rewriting our equation with parts separated

−5/6 −2−1/10

Solving the fraction parts

−5/6−1 1/0=?

Find the LCD of 5/6 and 1/10 and rewrite to solve with the equivalent fractions.

LCD = 30

−25/30−3/30= −28/30

Reducing the fraction part, 28/30,

−28/30= −14/15

Combining the whole and fraction parts

−2−14/15= −2 14/15

Solution by Formulas

converting mixed numbers to fractions, our initial equation becomes,

−5/6−21/10

Applying the fractions formula for subtraction,

=(−5×10)−(21×6)6×10

=(−50−126) / 60

= −176 / 60

Simplifying -176/60, the answer is

= −2 14/15

I hopes this helps!!! :)

25/4

step-by-step explanation:

call segment cd's length x. because dc and ab are parallel, angle acd and cab, so triangles adc and abc are similar and we can set up the equation x / ac = ac / ab, or x / 5 = 5 / 4 and x = 25/4.

answer: i would say b

step-by-step explanation:

with the way the question is worded, i believe b is the answer
