Answer:

x+7 =3(x-19)

Step-by-step explanation:

Given the statement:

Tim'S age in 7 years will be three times what it was 19 years ago.

Let the present age of Tim's age be x.

Tim's age in 7 years will be  = (x+7) years.

Tim's age was 19 years ago = (x-19) years.

"three times what it was 19 years ago" translated to 3 \times (x-19)

then, the equation we get;

x+7 =3(x-19)

We have to translate the given sentence into an equation.

Let the present age of Tim is x years.
His age in 7 years can be written as (x + 7) years
His age 19 years ago can be written as (x – 19) years

We are given that Tim’s age in 7 years will be 3 times his age 19 years ago.

So, we can write the equation as:

Tim’s age in 7 years = 3 x (Tim’s age 19 years ago)

x + 7 = 3 ( x – 19 )

Using this equation, the present age of Tim can be found.

Explain why please and make sure it is in full detail
Marysya12 [62]

Step-by-step explanation:

well,

(y - 7)² = (y - 7)(y - 7)

remember how to multiply 2 expressions ?

you have to multiply every term of one expression with every term of the other expression and sum the results all up (incl. considering their individual signs, of course).

so, when we do the multiplication, we get

(y - 7)(y - 7) = y×y - 7×y - 7×y + (-7)×(-7) =

= y² - 14y + 49

and that is clearly different to y² - 49

FYI

y² - 49 is the result of

(y - 7)(y + 7)

because

y×y + 7×y - 7×y + (-7)(7) = y² - 49

Answer:

<h2>             m∠ABC = 30°</h2>

Step-by-step explanation:

m∠BAD = 0.5m∠BCD = 0.5•126° = 63°

The  angles in quadriteral add to 360°, so:

m∠ABC + m∠BAC + m∠ACD + reflex m∠BCD = 360°

m∠ABC + 63° + 33° + (360° - 126°) = 360°

m∠ABC + 96° - 126° = 0

m∠ABC = 30°
