First of all, the identity property of multiplication (which is what this is I'm assuming) is that the number 1 multiplied by any other number is that number itself. (An example would be 2 multiplied by 1, which would be two) So in this problem, this rule applies too, since 2/3 multiplied by 1 would be 2/3!

Hope this helped :)

Solve the following equation, answer as a reduced, mixed number. Then place the correct number in the box provided. 4(3 - 2x) =
valentinak56 [21]

Answer:

x = -3/8

Step-by-step explanation:

4(3 - 2x) = 15

Distribute

12 -8x = 15

Subtract 12 from each side

12-8x-12 =15-12

-8x =3

Divide by -8

-8x/-8 = 3/-8

x = -3/8

17. Classify Each Angle Pair then find the value of X
IRISSAK [1]

<u>Given</u> -

  • If l || m, m∠1 = (13x + 24)°, and m∠2 = (5x-6)°,

<u>To find</u> -

  • m∠2.

<u>Concept</u> -

Whenever two parallel lines are cut by a transversal, an interesting relationship exists between the two interior angles on the same side of the transversal. These two interior angles are supplementary angles. Hence, according to the figure l and m are two parallel lines and t is the transversal intersecting them then ∠1 + ∠2 = 180°.

<u>Solution</u> -

\rightarrow\sf{(13x+24)^{ \circ}+(5x-6)^{ \circ}=180^{ \circ}}

\rightarrow\sf{13x+5x+24-6=180}

\rightarrow\sf{18x+18=180}

\rightarrow\sf{18x+18=180}

\rightarrow\sf{18(x+1)=180}

\rightarrow\sf{x+1=\frac{180}{18}}

\rightarrow\sf{x+1=10}

\rightarrow\sf{x=10-1}

\rightarrow\boxed{\bf{x=9}}

m∠2 = (5x-6)° = {5(9) - 6}° = {45 - 6}°= 39°

Henceforth, m∠2 = 39°

Before beginning a vigorous aerobic exercise routine all adults should
Roman55 [17]
You should probably warm up with a stretching routine and a light job, because all your muscles (including your heart) cannot remain healthy and will be overworked if you dive into a vigorous aerobic routine without a proper warm up.
