Answer:

7.27

Step-by-step explanation:

To make it easier to divide fractions, you multiply them by switching the second fraction around: 6/7 => 7/6

Then you switch the division symbol to a multiplication symbol.

Then you multiply the top numbers of the fractions first:

2 x 7 = 14

Then the bottom numbers:

9 x 6 = 54

So the fraction you end up with is 14/54.

Then you reduce by finding the GCF and dividing both numbers by that number. (The GCF is the greatest common factor that both numbers have, which is the highest number that is divisible by both numbers - an example would be the GCF of 6 and 9, which would be 3.)

The GCF of 14 and 54 is 2. Therefore, we divide 14 by 2 which would be 7. Then we divide 54 by 2, which would be 27. Since 7 and 27 do not have a GCF;

<u><em>7/27 is the reduced form</em></u>

Daniel wants to prove that the interior angles of any triangle sum to 180°. He draws a line through one vertex parallel to the o
Serggg [28]

Alternate interior angles theorem.

<u>Step-by-step explanation:</u>

By using the definition of Alternate Interior Angles theorem, we can say that If a transversal cuts any two parallel lines, then those pairs of alternate interior angles are seems to be  congruent.

So in the given triangle,

∠4 ≅ ∠2

∠5 ≅ ∠3

Sum of all the angles in a triangle = 180°

∠1 + ∠2 + ∠3 = 180°

Since from the above congruence, we can write that

∠1 + ∠4 + ∠5 = 180°

Hence proved.

Which of the following expressions are equivalent to 7.2 ÷ -8.1 ÷ -3.7?
Inessa05 [86]

Step-by-step explanation:

7.2 / (-8.1) / (-3.7) = Positive

A = (-7.2) / (-8.1) / (-3.7) = Negative

B = (-7.2) / (8.1) / (3.7) = Negative

Hence the answer is C, none of the above.

the width of a rectangle is 8 feet and the diagnal length of the rectangle is 13 feet which measurement is closest to the length
____ [38]

Answer:

Well the whole answer is 10.246950 smth smth but I don’t have the multiple choices so your gonna have to round yourself

Step-by-step explanation:

Okay so you have a weigh of 8 and a diagonal of 13.

If you look, theres a triangle there. One side has 8 and the diagonal that was cut forms a 13. So we have a leg and a hypotnuse. To find the other leg (length) just follow the Pythagorean theroum and solve for b or a.

Pythagorean theroum: a^2+b^2=c^2

Now subsitute c for 13 since its the hypotnuse and a or b as 8 but only one.

In this case I’m substituting a for 8.

8^2+b^2=13^2

Solve the squares

64+b^2= 169

Isolate the b

b^2=105

Now square root 105

√105 will give the answer above on a normal calculator but if you have to round, I don’t know what place but you can round.

Evaluate the expression 4(2x + 3) + 2(x + 1)-7
Svetlanka [38]
4 (2x + 3) + 2 (x + 1) - 7

8x + 12 + 2x +  2 - 7

10x + 7

10x = -7
10x/10 = -7/10

x = -7/10

hope this helps
