$-4x + 5 \left(\dfrac{20}{11}\right) =-4\\\\\implies \dfrac{100}{11} = -4+4x\\\\\implies 100 = -44+44x\\\\\implies 44x = 100 +44 = 144\\\\\implies x = \dfrac{144}{44} = \dfrac{36}{11}$

In this figure, AB⎯⎯⎯⎯⎯∥CD⎯⎯⎯⎯⎯⎯ and m∠3=120°.

AfilCa [17]

Answer:

60°

Step-by-step explanation:

∠3 and ∠6 are called same-side interior angles. This is because they are inside the parallel lines and on the same side of the transversal.

Same-side interior angles are supplementary; this means their sum is 180°. Since m∠3 = 120°, this means that m∠6 = 180-120 = 60°

andrey2020 [161]

Answer:

After using distributive property to remove the parentheses $10(u-2)$ we get $10u-20$

Step-by-step explanation:

We need to use distributive property to remove the parentheses 10(u-2)

According to distributive property of multiplication over subtraction: $a(b-c)=ab-ac$

Using the above distributive property to solve the question. Multiply 10 with terms inside the bracket and solving:

$10(u-2)\\=10u-10*2\\=10u-20$

So, After using distributive property to remove the parentheses $10(u-2)$ we get $10u-20$
