Answer:

The resulting equation is 2y-8 + 5y - 10 = 0

Step-by-step explanation:

For the following system, use the second equation to make a substitution for x in the first equation.

x + 5y - 10 = 0 first equation

x = 2y - 8  second equation

Now substitute the second equation in first equation

Replace x with 2y-8 in first equation

x + 5y - 10 = 0

2y-8 + 5y - 10 = 0

The resulting equation is 2y-8 + 5y - 10 = 0

What is the answer to this question about dividing fractions5 5⁄6 ÷ 3 2⁄4=
Lady_Fox [76]

[~Answer~] (4.):
<em>Hello there! I'm Avery, and I'm here to help you! I mostly believe the answer </em><em>is 1 2/3


+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
</em>

[~Answer Explanation~]:

First:

Convert any mixed numbers to fractions.

Reduce fractions where possible.

Then your initial equation becomes:

356÷72

Applying the fractions formula for division,

=35×26×7

=70/42

Simplifying 70/42, the answer is

=1 2/3

Based on the information given say whether or not △ABC∼△FED. Explain your reasoning.
GalinKa [24]

Answer:

Yes, △ABC ∼ △FED by AA postulate.

Step-by-step explanation:

Given:

Two triangles ABC and FED.

m∠A = m∠B

m∠C = m∠A + 30°

m∠E = m∠F = x

m∠D = 2x-20°.

Now, let m∠A = m∠B = y

So, m∠C = m∠A + 30° = y+30

Now, sum of all interior angles of a triangle is 180°. Therefore,

m∠A + m∠B +  m∠C = 180

y+y+y+30=180\\3y=180-30\\3y=150\\y=\frac{150}{3}=50

Therefore, m∠A = 50°, m∠B = 50° and m∠C =  m∠A + 30° = 50 + 30 = 80°.

Now, consider triangle FED,

m∠D+ m∠E + m∠F = 180

2x-20+x+x=180\\4x=180+20\\4x=200\\x=\frac{200}{4}=50

Therefore,  m∠F = 50°  

m∠E = 50° and  

m∠D =  2x-20=2(50)-20=100-20=80\°

So, both the triangles have congruent corresponding angle measures.

m∠A = m∠F = 50°

m∠B = m∠E = 50°

m∠C = m∠D = 80°

Therefore, the two triangles are similar by AA postulate.
