forsale [732]4 years ago
5 0

Answer:

<u>Yes</u>

  • (2 · x) + (2 · 7) = 36
  • x + 7 = 18
  • 2x + 14 = 36

<u>No</u>

  • 2x + 7 = 36
  • 2(x + 7) = 72
  • x + 14 = 36

Step-by-step explanation:

It is appropriate to eliminate parentheses as a first step. This can be done using the distributive property, resulting in either of ...

  • 2x +2·7 = 36
  • 2x +14 = 36 . . . . . 2·7 evaluated mentally

or by dividing the equation by the factor outside parentheses, resulting in ...

  • x + 7 = 18

___

Any of the equations other than these represent violations of the equal sign. Something has been done to one side of the equation without the same thing being done to the other side.

Parallelogram ABCD is given. Draw line EF so that it goes through the vertex A. Point E lies on the side BC and point F lies on
tresset_1 [31]

Answer:

The proof is explained step-wise below :

Step-by-step explanation :

For better understanding of the solution see the attached figure :

Given : ABCD is a Parallelogram ⇒ AB ║ DC and AD ║ BC

Now, F lies on the extension of DC. So, AB ║ DF

To Prove : ΔABE is similar to ΔFCE

Proof :

Now, in ΔABE and ΔFCE

∠ABE = ∠FCE ( alternate angles are equal )

∠AEB = ∠FEC ( Vertically opposite angles )

So, by using AA postulate of similarity of triangles

ΔABE is similar to ΔFCE

Hence Proved.

Kesia knows that 1/4 = 0.25. Explain how she could use this fact to determine the decimal equivalent of 5/8.
guapka [62]
Well if you split 1/4 in half then that will give 1/8. You must also split 0.25 in half which gives 0.125
\frac{1}{8} = 0.125
Now you can multiply that by 5 which gives 5/8. But also the fraction
\frac{1}{8} \times 5 = 0.125 \times 5 \\&#10;\frac{5}{8} = 0.625
Now we know that 5/8 = 0.625
